4-1 CHAPTER 4. CERTIFICATION

4.1 Scope and Contents. This chapter outlines the usual sequence of events in the certification process.

4.2 Application Acknowledgment Letter.

4.2.1 Receipt of Application Acknowledgment. Upon receipt of your Preapplication Statement of Intent (PASI), the Flight Standards District Office (FSDO) will issue a letter acknowledging receipt. In addition, the letter will notify you if they have the resources to start processing your request.

4.2.2 Application Processing Notification. If the FSDO cannot start processing your request normally within 60 calendar-days, you will be notified. When the FSDO is able to begin processing your request, a subsequent letter will be sent notifying you that the FSDO can begin processing your request.

4.3 Inspection Team. The district office will normally assign a team of inspectors from operations, airworthiness, and avionics specialties. This team is commonly referred to as the Certificate Management Team (CMT). The CMT will have a Certification Project Manager (CPM) assigned; usually this will be the operations specialist but could be an airworthiness or avionics specialist. The CPM will normally be the point of contact (POC) between the CMT and the applicant. The CMT will assist you during the certification process, and answer your questions. They will review your submitted documents and perform the required inspections. You will be responsible for submitting documentation, and being ready for the necessary inspections in accordance with your submitted Schedule of Events (SOE). If you are unable to consistently meet your SOE, or are unable to complete the certification process, your certification will be terminated and you will be notified by letter. You can re-apply at any time after termination; however, your application will be processed in the order in which it is received, and you will have to start the certification process again, from the beginning, starting with the PASI.

4.4 Certification Procedures. This section provides the procedures for certificating a part 125 operator. The process allows interaction between the applicant and the FAA from initial inquiry to certificate issuance or denial. It ensures that programs, systems, and intended methods of compliance are thoroughly reviewed, evaluated, and tested. The certification process consists of the following five phases:

• Preapplication Phase,

• Formal Application Phase,

• Document Compliance Phase,

• Demonstration and Inspection Phase, and

• Certification Phase.

4-2

4.5 Preapplication Phase.

4.5.1 Review the Regulations and Requirements. The submission of FAA Form 8400-6, Preapplication Statement of Intent (PASI), indicates intent by the applicant to continue the certification process. It also allows the FAA to plan activities and commit resources.

Therefore, a potential applicant submits a copy of the PASI after reviewing the appropriate regulations and advisory material and considering the personnel, facility, equipment, airplane, and document requirements for certification and operation.

4.5.2 Proposed Certification Review. The FSDO manager uses the PASI to evaluate the complexity of the proposed certification, and if it is appropriate for the office to conduct the certification. The office manager ensures that trained and experienced inspectors are available for the certification.

4.5.3 FSDO Resources. The FSDO will gather and summarize the PASI information and start the Certification Service Oversight Process (CSOP), if office resources are available.

4.5.4 Preapplication Meeting. The CPM shall contact the applicant to arrange a preapplication meeting. The applicant is advised that key management personnel, as shown on the PASI, should attend the meeting and be prepared to discuss specific aspects of the applicant’s proposed operation. During the preapplication meeting, the CPM should ensure the applicant is informed about the certification process. The CPM will also discuss the form, content, and documents required for formal application.

4.5.5 Documents and Manuals. The CMT will furnish guidance and advice for the preparation of required documents and manuals. It is the responsibility of the applicant to produce acceptable documents and manuals.

4.5.6 Submitting Required Items. The applicant may submit required items in draft form before submitting the formal package. Whenever a problem or change occurs in the proposed operation, the applicant should notify the CPM immediately.

4.5.7 SOE Development. The applicant will need to develop an SOE. The SOE is intended to encourage you to submit material well in advance of the date operations are proposed to begin. If, however, the application is submitted with only the minimum lead time required by the regulation, complete documents (such as, the Policy and Procedures Manual (PPM)) may be required at the time of formal application. The SOE will contain the dates and the events, associated with those dates, when the CMT can expect documents and material from you, and when you will be ready for inspection and demonstration events. The SOE, when accepted, represents a commitment on the part of the applicant.

4.5.8 Sequence of Events. When developing the SOE, the applicant must remember the correct sequence of events. For example, airplane conformity inspections must be completed before emergency evacuation demonstrations begin.

4.5.9 Events and Activities. The number and types of events and activities that occur during certification vary according to the operation proposed. The SOE must include a complete

4-3 listing of each document to be submitted, activity to be performed, and item to be inspected.

4.5.10 Certification Delays or Termination. Failure to accomplish an item or event in a satisfactory or timely manner in accordance with the SOE could delay or terminate certification. In addition, if deficiencies are detected during the review of manuals or other documents, they will be returned for amendment or correction, which also may delay final certification.

4.5.11 Deviation Petition. If the applicant plans to petition for deviation, processing time must be considered in developing the SOE. Part 125, § 125.3 requires that a petition for deviation must be submitted to the appropriate FSDO at least 60 calendar-days before the date of intended operation.

4.5.12 Proposed Schedule. When reviewing the SOE, the team must carefully consider the feasibility of the proposed schedule with respect to logic of sequence, timeliness of events, completeness of events, and inspector availability.

4.6 Formal Application Phase. The Formal Application Phase is described in Chapter 3, paragraph 3.17. In addition to the information in paragraph 3.17, the applicant may want to have all of their documentation ready for review at the time of formal application.

Although not necessary, completion of most or all the documentation at the formal application meeting will reinforce, to the FSDO, the applicants willingness and commitment to see the certification process through to certification.

4.7 Document Compliance Phase.

4.7.1 Document Review. In the Document Compliance Phase, the applicant’s compliance statement, manuals and other documents are thoroughly reviewed for compliance with applicable regulations and for conformity with safe operating practices. After review by the CMT, each document is accepted or approved, as applicable, or rejected.

4.7.2 Operations Specifications (OpSpecs). OpSpecs outline the specific operations which a part 125 certificate holder is allowed to conduct and any deviations the certificate holder has been granted. They also supplement the operating rules and contain limitations not addressed in the regulations. Often the regulations require that certain authorizations and limitations be written in the OpSpecs. For example, § 125.363(d) states that the minimum requirements for over water operations will be indicated in the OpSpecs. This could include additional requirements for emergency equipment or personnel required for that particular operation but not indicated in the regulation.

4.7.3 The Policy and Procedures Manual (PPM). Section 125.71 requires a part 125 air operator to prepare and keep current a manual which describes the operator’s procedures and policies. The manual is for use by all of the operator’s personnel and also indicates to the FAA how the operator intends to conduct its operation. The manual’s complexity depends upon the complexity of the operation. As a general rule, if the applicant submits the formal application only 60 calendar-days before operations are scheduled to begin

4-4 and draft documents were not previously submitted, the team may require that additional manual material be submitted at the time of formal application.

4.7.3.1 The CMT will review the company PPM to determine that it:

1. Contains adequate procedures and policies concerning all items listed in §§ 125.73 and 125.249, and similar information relating to §§ 125.401, 125.403, 125.405, 125.407, 125.409, and 125.411.

2. Contains any other procedures and policies necessary to meet any unique operations conducted by the company or authorized by the OpSpecs.

3. Does not contain procedures or policies contrary to the applicable CFRs or OpSpecs.

4.7.3.2 The operator will maintain a copy of this manual at their principal operations base (refer to § 125.7l (b)) and make copies available to ground and maintenance personnel and furnish copies to flightcrew members as outlined in § 125.7l (d).

4.7.3.3 Manuals not acceptable to the certification team will be returned to the applicant for revision and/or correction with a letter stating what the CMT found as unacceptable.

4.7.4 Management Positions. The position of Director of Operations (DO) is the only management position specified by § 125.25. The chief pilot’s position is only a suggested position. Additionally, § 125.25 states that management personnel be enough “to assure that its operations are conducted in accordance with the requirements of part 125”. The applicant may elect not to have any management positions other than director of operations, or the applicant may have more positions. In that case, qualifications are up to the judgment of the certification team, based on the type of management position and the complexity of the operation.

4.7.5 Acceptable Weight and Balance (W&B) Procedures. Acceptable W&B procedures may be found in the current edition of Advisory Circular (AC) 120-27, Aircraft Weight and Balance Control. Material from this publication, can be cited as a resource and adapted to the applicant or operator’s procedures, but reference to these publications as a means of compliance is not acceptable. Certain W&B procedures described in AC 120-27 require authorization.

4.7.6 Hazardous Materials (Hazmat) Program. Although a training program is not required by part 125, the operator should be encouraged to prepare a hazmat program for all flightcrew members and ground personnel. Whether or not an operator elects to transport hazmat, the company manual required by § 125.73 must include certain procedures and instructions relating to hazmat. Some form of training in this area should be addressed.

There are numerous all-cargo operators, with approved hazmat training programs, who could be contracted with to provide initial and recurrent training. (The inspector might consider keeping a current list of such operators as a resource.) If the operator uses a

4-5 training program, it should have provisions for regular testing of flightcrew members on the operator’s hazmat policies and procedures.

4.7.7 Initial Compliance Statement. An applicant may submit an initial compliance statement with the formal application package because methods of compliance may depend on actions by the FAA (i.e., approval of the manual). When the method of compliance is finally formalized, the description can be added to the list in preparation for the final compliance statement. However, the SOE must show when the final compliance statement will be submitted.

4.8 The Demonstration and Inspection Phase.

4.8.1 Inspection Teams. In the Demonstration and Inspection Phase the certification team determines that the applicant’s proposed procedures and programs are effective and that facilities and equipment are satisfactory. Inspection teams will visit your principal business office and operations base. Inspectors will review provisions you have made to satisfy the policies and procedures in your proposed OpSpecs and company manuals, such as flight release, W&B, flight locating, airplane checklists, passenger briefing, etc.

You must have adequate provisions to conduct operations.

4.8.2 Regulations and Safe Operating Practices. Emphasis is on compliance with regulations and safe operating practices. Throughout the Demonstration and Inspection Phase the CPM will ensure that each required demonstration is observed and approved or disapproved. If at any time during this phase the applicant does not meet the SOE or if an activity or item proves to be deficient, the CPM will take appropriate corrective action.

The CPM will schedule meetings with the applicant to review deficiencies in detail. Each deficiency and corrective action must be fully documented and placed in the certification file. If appropriate, the CPM will terminate the certification process, or agree to a modified SOE.

4.8.3 Airplane Inspections. All airplanes the operator intends to use in its operation will be inspected to:

1. Determine that they are properly registered and carry a registration certificate.

2. Determine that they are certificated and carry an appropriate airworthiness certificate.

3. Determine that the airplane empty weight and center of gravity (CG) have been calculated on the basis of an actual weighing within 36 calendar-months.

4. Ensure that the requirements of part 125 subpart E have been met.

5. Ensure that the requirements of part 125 subpart F, as appropriate to the operation to be conducted, have been met.

6. Determine that the engines conform to the maintenance program requirements for § 125.247(d).

4-6

7. Determine that all items on the airplane have been inspected in accordance with the inspection schedule established in the inspection program required by § 125.247.

8. Determine that an appropriate approved Airplane Flight Manual (AFM) is on board.

9. Determine conformity with the airplane type certificate data.

10. Ensure that it is in a condition for safe operation.

Note: The CMT will also review the AFM with emphasis on those portions which were modified to accommodate your particular operation (refer to § 125.75(b)).

4.8.4 The Emergency Evacuation Demonstration. Effective emergency evacuation procedures have significantly reduced the number of casualties in survivable airplane accidents. The FAA considers an applicant’s or operator’s ability to perform these procedures to be an extremely important aspect for aviation safety.

4.8.5 Aborted Takeoff Evacuation. Part 125 operators and applicants for a part 125 certificate must conduct a full-scale aborted takeoff evacuation demonstration for any airplane having a seating configuration of more than 44 passenger seats. The evacuation must be completed in 90 seconds or less (refer to § 125.189).

4.8.5.1 This demonstration is not required for certification if you have:

1. Previously conducted this test in the same airplane under 14 CFR part 121, § 121.291(b).

2. Previously demonstrated this evacuation using an airplane of the same type and configuration under part 125.

4.8.5.2 Specific instructions for preparing and conducting the emergency evacuation demonstration are found in part 125 appendix B.

4.8.6 Ditching Evacuation. All part 125 operators and applicants for a part 125 certificate must conduct a full-scale ditching evacuation demonstration for any land airplane intended for use by the operator in extended overwater operations.

4.8.7 Records. Part 125 subpart L indicates the types of records which must be maintained by a part 125 operator. Sections 125.403, 125.405, 125.407, 125.409, 125.411, and the operator’s manual contain details about the approval of procedures for flight release forms; disposition of the load manifest, flight release, and flight plans; airplane maintenance logs; reports of defects or un-airworthy conditions; and airworthiness release or maintenance record entries. The inspector should refer to those sources to check those records. Records should be kept in a manner easily accessible to inspectors.

The method of storage is, of course, the choice of the operator, but retrieval and review should not require an extended or complicated process.

4-7

4.8.8 Corrective Action Notification. After resolving any discrepancies with any of the documents or the inspections, the applicant must notify the CPM, in writing, detailing the corrective action taken. The demonstration and inspection phase should then be continued.

4.9 The Certification Phase.

4.9.1 Issued Certificates and OpSpecs. In the Certification Phase, the certificate and approved OpSpecs are issued after all unsatisfactory items are corrected. No certificate shall be issued until the team determines the applicant is fully capable of fulfilling responsibilities as charged by Title 49 of the United States Code (49 U.S.C.).

4.9.2 OpSpecs Review. The CMT will review the OpSpecs to determine that they:

1. Contain adequate provisions to meet all items listed in § 125.31(b).

2. Contain any other provisions applicable to your operations.

3. Do not contain information that is contrary to the applicable CFRs.

4. Contain reference to any deviations authorized.

4.9.3 Certificate Issuance. A certificate is issued to the applicant when the following criteria are met:

1. The certification process is completed.

2. Each unsatisfactory item has been corrected.

3. It is determined that the applicant has met all regulatory requirements and understands all responsibilities under the regulations.

4. It has been determined the applicant is capable of complying with the part 125 on a continuing basis.

5. The applicant’s ability to conduct operations in a safe manner has been demonstrated.

4.9.4 Amended Certificates. If a certificate is amended to reflect an address change or a change of the assigned district office, the date of original issuance shall be shown on the new certificate.

4.9.5 Legal Name Changes. A change of official name must be approached with care.

Whatever the complexity of the legal name change, it has the effect of a new certification; therefore, a new certificate and certificate number shall be issued. For this situation the issuance date of the new certificate will be entered in the space provided on the certificate.

4-8

4.10 Designation of a Check Airman.

4.10.1 Check Airman Qualifying Evaluations. If you request approval of a check airman and the FAA finds that this approval is warranted by operational factors and your nominee is acceptable, he/she must complete the qualifying evaluations.

4.10.2 Instrument Proficiency Test. He/she must complete the instrument proficiency test provided in § 125.291. He/she will conduct flight test(s) of other company flightcrew members while being observed by an FAA inspector. Assuming he/she successfully completes these tests, the company will be issued a letter of authorization (LOA) authorizing the use of a check airman.

Note: Further information regarding check airmen is contained in Chapter 3 and Chapter 8.

4.11 Testing of Crewmembers.

4.11.1 Records Review. The check airman or FAA inspector conducting the crewmember testing will review the company records required by § 125.401 for these crewmembers.

The flightcrew members will be requested to present their airman and medical certificates and logbooks for review.

4.11.2 Initial and Recurrent Pilot Testing. All pilot crewmembers must successfully complete the 12-month test required by § 125.287 before they can serve as a pilot. An FAA Form 8410-1, Airman Proficiency/Qualification Check, will be used to document the results of that test. A copy of the completed form should be maintained in the company records.

4.11.3 Electronic Testing System (ETS). An ETS may be used to satisfy the requirements of § 125.287(a)(1), with the exception that testing on OpSpecs and the manual of the certificate holder is a specific testing requirement for each individual operator and may not be applicable to a generic ETS system. If an ETS system is used to test OpSpecs and the manual of an individual operator, it must be applicable to the specific operator and cannot be used until approved by the principal operations inspector (POI). In addition, § 125.287(a)(4) through (9) may use an ETS system to satisfy the testing requirements, but must be approved by the POI prior to use. Minimum testing requirements using an ETS system will be established by the operator and approved by the POI. A minimum passing score of 70 percent corrected to 100 percent is recommended.

4.11.4 Instrument Proficiency Check (IPC). Pilots who will serve as a pilot in command (PIC) must successfully complete the IPC required by § 125.291. A letter of competency will be issued following the successful completion of the IPC. A copy of this document should be maintained in the company records.

4.11.5 Flight Attendant (F/A) Testing. The certificate holder is responsible for the testing of an F/A’s knowledge and competency per § 125.289.

Note: Further information regarding crewmember qualification is provided in Chapter 8.

4-9

4.12 Maintenance Considerations.

4.12.1 Part 125 Certificate Holders. The holder of a part 125 operating certificate is not authorized under that certificate to accomplish maintenance or return the airplane to service after maintenance. This does not preclude a certificate holder from employing certificated mechanics who can perform these functions on the authority of their certificates or providing the facilities necessary for the accomplishment of the maintenance. A part 125 certificate holder may also hold a certificate under 14 CFR part 145 for a repair station. In this case, airplane maintenance and return to service may be accomplished under the authority of the part 145 certificate holders, provided the repair station holds the appropriate ratings. Under part 125, the certificate holder is able to provide for maintenance through one of these methods, it will be necessary to provide for scheduled and/or routine maintenance through agreements with other organizations which have the appropriate authority and ratings to accomplish the maintenance.

4.12.2 Agreements and Provisions for Maintenance. During the certification process, the FAA will review your agreements with other organizations for maintenance, and any other provisions you have made for the accomplishment of maintenance, to assure that you have provided for all aspects of scheduled and unscheduled maintenance. If you have elected to provide the facilities for the maintenance of your airplanes, these facilities and the authority which will be used to perform the maintenance and return the airplane to service will be subject to review and inspection. All aspects of the facilities and personnel will be evaluated regarding understanding of your manual, personnel qualifications, experience, equipment, and the overall ability of the facility to produce a properly inspected and maintained airplane. This will also be true in respect to avionics functions.

Note: Additional information on airplane inspection programs is found in Chapter 9.

4.13 Issuance of Operating Certificate.

4.13.1 Successful Completion of Tests/Inspections. You will be issued a part 125 operating certificate upon successful completion of the tests and inspections discussed in this chapter (refer to § 125.27(a)).

4.13.2 Certificate Display. A copy of the certificate must be displayed in each airplane used for part 125 operations (refer to § 125.7(a)).

4.14 Approval of OpSpecs. The applicable OpSpecs will be processed in the FAA’s Web-based Operations Safety System (WebOPSS) and electronically signed by the operator, if the operator has made provisions for WebOPSS electronic signature, and the principal inspector (PI). If the operator does not have WebOPSS electronic signature authority then the designated company representative will hand sign each applicable OpSpecs. You should retain the original at your principal base of operations, and place a copy in your company’s PPM.

4.15 Final Certification. Upon receipt of the operating certificate, approved OpSpecs, and accepted company manual, certification is complete. You are now a part 125 certificate holder.

5-1 CHAPTER 5. FAA SURVEILLANCE AFTER CERTIFICATION

5.1 Scope and Contents. This chapter explains surveillance that the FAA conducts on 14 CFR part 125 certificate holders. The listed inspections are not an exhaustive list, but outline the major inspections you can expect as a part 125 certificate holder. Inspectors are authorized to conduct other inspections, as necessary, to ensure the operator is in compliance with the Federal aviation regulations, applicable to their operation.

5.2 Inspection Authority.

5.2.1 Administrator Authority. Part 125, § 125.45 states that each certificate holder shall allow the Administrator, at any time or place, to make any inspections or tests to determine an operator’s compliance with the Federal Aviation Act of 1958, the Federal Aviation Regulations, its operating certificate and operations specifications (OpSpecs), its Letter of Deviation Authority (LODA), or its eligibility to continue to hold its certificate or LODA.

5.2.2 Types of Inspections. In the course of exercising this inspection authority, FAA inspectors (operations and airworthiness) conduct facility (base) inspections, ramp inspections, airplane inspections, en route inspections, and other related surveillance.

5.3 Identification of Inspectors. All FAA inspectors authorized to conduct inspections have an inspector credential (FAA Form 110A, Aviation Safety Inspector’s Credential) which identifies them as an inspector. The certificate holder’s personnel may request to see this credential when approached by any aviation safety inspector (ASI) when that inspector is present to conduct any authorized inspection.

5.4 Facility (Base) Inspections. These inspections are conducted on a recurring basis to ascertain that the certificate holder’s facilities continue to meet the original certification standards.

5.5 Ramp Inspections. The FAA conducts announced or unannounced surveillance of airplanes which have just completed, or are about to engage in, flight operations. The major items reviewed in these inspections include, but are not limited to: flightcrew certification, flight and duty time limitations, instrument and equipment requirements, Weight and Balance (W&B) limitations and procedures, minimum equipment list (MEL) procedures (as applicable), flight locating requirements, or any other issues that may affect the safety of the flight.

5.6 En Route Inspections.

5.6.1 Flight Deck Inspection. During an en route inspection, the FAA inspector will ride on the flight deck and observe and evaluate crew performance during a part 125 operation.

Inspectors are authorized to make this inspection, on an announced or unannounced basis, provided they identify themselves by presenting their credentials and a copy of a completed FAA Form 8430-13, Request for Access to Aircraft, to the certificate holder or his/her representative (i.e., pilot in command (PIC)).

5-2 Note: In addition to a flight deck inspection, an FAA inspector may conduct a cabin en route inspection to verify that the cabin crew adheres to all applicable regulations and the applicable company policies and procedures.

5.6.2 Access to Flight Deck. Certificate holders should make their flightcrews aware of the requirements of §§ 125.315 and 125.317. An ASI who presents the proper credentials must be allowed free and uninterrupted access to the pilot compartment of the airplane.

Failure to allow this access, except in cases involving the invoking of the emergency authority of the PIC, may result in enforcement action against the pilot and/or certificate holder.

5.6.3 Inspection Briefing. Inspectors should brief the PIC of their findings at the termination of the flight and, as necessary, advise company management personnel.

5.7 Airplane Inspections. FAA airworthiness inspectors will conduct scheduled or nonscheduled inspections of airplanes operated under part 125 on a regular basis to determine that the airplanes continues to meet the original standards for certification.

5.8 Simulator Surveillance. FAA inspectors will conduct periodic surveillance of simulators and flight training devices (FTD), to ensure they meet the requirements of §§ 125.296 and 125.297. Principal operations inspectors (POI) may utilize the Training Center Program Manager (TCPM) to assist him/her in the surveillance of simulators used by a part 125 operator.

5.9 Check Pilot Surveillance. POIs are responsible for providing surveillance over all individuals assigned as check pilots/contract check pilots for their assigned air operators.

POIs will observe authorized check airmen conduct oral and flight tests, on an annual basis, to assure that applicable standards and procedures are being used. Contract check airman employed by an approved 14 CFR part 142 training center will be observed every 24 calendar-months. With regard to authorized contract check airman employed by approved part 142 training centers, the POI may ask TCPMs to assist them in the observation of contract check pilots assigned to their air operators.

5.10 Additional Information. Additional information can be found at the FAA’s Web site at http://fsims.faa.gov.

6-1 CHAPTER 6. OPERATIONAL CHANGES

6.1 Scope and Contents. This chapter outlines changes to your operation which will require that you inform, or receive the approval of, the FAA prior to implementation.

6.2 Change of Ownership.

6.2.1 Certificate Transfer. A 14 CFR part 125 operating certificate cannot be transferred from one person to another. Upon change of ownership, the FAA will suspend the operating certificate under the provisions of part 125, § 125.29. A determination will be made that the new owner’s operation meets the certification requirements of part 125.

6.2.2 Coordination Prior to Ownership Change. Purchasers of a company holding a part 125 operating certificate may avoid having the company’s operations interrupted through coordination with the Flight Standards District Office (FSDO) that issued the certificate prior to the transfer of ownership.

6.2.3 Certification Process and Requirements. The new purchaser may not have to complete all steps of the certification process if the FAA determines that no significant changes to the basis for original certification of the company or its operations under part 125 will occur as a result of the transfer of ownership. However, the jurisdictional FSDO may require the new owner to meet some or all of the requirements for a new certification, depending on the degree of change that occurs within the company as a result of new ownership. If significant changes occur as the result of a change of ownership, the jurisdictional FSDO will decide, based on those changes, what steps of the certification process will have to be completed by the new owners prior to part 125 operations.

6.3 Voluntary Surrender of Certificate and Operations Specifications (OpSpecs).

6.3.1 Cancellation Requests. Certificates and OpSpecs which are voluntarily surrendered for cancellation should be accepted. The certificate must be accompanied by a written request from the operator stating the reason for cancellation. The request must be signed by either a person authorized to act for the company, or by the owner. This request may not be conditional.

6.3.2 Lost or Destroyed Certificates and OpSpecs. If the operating certificate or OpSpecs have been lost or destroyed, a statement by the certificate holder to this effect should be included in the written request for cancellation.

6.4 Change of Business Name or Address.

6.4.1 Amendment Application. A part 125 operator may apply to amend either the operating certificate or the OpSpecs. The FAA may also amend the operating certificate or the OpSpec as the result of actions taken under Title 49 of the United States Code (49 U.S.C.) § 44709 and 14 CFR part 13.

6.4.2 Applications for Name or Address Changes. If the certificate holder wishes to change the legal name on a certificate or change the address of its principal business office or its
