2-1 CHAPTER 2. APPLICABILITY OF PART 125
2.1 Scope and Contents. This chapter provides guidance regarding the applicability of 14 CFR part 125 to certain large airplane operations in other than common carriage, and the exceptions to this applicability.
2.1.1 Types of Operations. According to 14 CFR part 375, § 375.40(b), an operator that holds itself out to the public, or to a particular class or segment, as willing to furnish transportation for hire is a common carrier. Part 125 provides for the operation of large airplanes that are not conducting operations in common carriage, including the following types of operations:
1. Non-common carriage for hire operations. This type of operation is allowed, but must be reviewed carefully to verify that the operation is not common carriage. Operators are not permitted to hold out to the public directly or indirectly.
2. Private carriage operations in which persons or cargo are transported without compensation or hire; for example, private or corporate operators carrying company personnel, property, and guests, including cost sharing under 14 CFR part 91, § 91.501(d).
3. Parachute, lease/sale agreements, or historic (museum or collection) flight operations.
4. Operations not involving the transportation of persons or cargo.
2.2 Applicability: Seating vs. Payload Capacity.
2.2.1 Determination of Applicability. The determination of applicability for part 125 is: Does the operator use an airplane with a seating capacity (configuration) for 20 or more passenger seats or a maximum payload capacity of 6,000 pounds or more?
2.2.2 Seating Capacity. If the airplane has 20 or more passenger seats, part 125 is applicable.
However, the operator could reconfigure the airplane (remove the seats) so that it has a passenger seating capacity of 19 or less. In this situation, part 125 would not be applicable, unless the calculated maximum payload capacity is 6,000 pounds or more.
2.2.3 Maximum Payload Capacity. Maximum payload capacity is defined in part 125, § 125.9.
If, through calculations in accordance with this definition, the maximum payload is determined to be 6,000 pounds or more, part 125 is applicable regardless of the number of seats.
2.2.4 Exceptions. Exceptions to the applicability of part 125 are discussed in paragraph 2.5.2.
2.3 Compensation Permitted. Part 125 is applicable to large airplane operations in other than common carriage. A person is considered to be engaged in common carriage when holding out to the general public or to a segment of the public as willing to furnish transportation within the limits of its facilities to any person who wants it. Advertising
2-2 through telephone yellow pages, billboards, television, radio, internet Web sites, social media, and individual ticketing are examples that have been legally found to be holding out. Section 125.11(b) prohibits part 125 certificate holders from conducting any operation which results directly or indirectly from holding out to the general public.
Further information regarding common carriage vs. private carriage can be found in the current edition of Advisory Circular (AC) 120-12, Private Carriage Versus Common Carriage of Persons or Property.
2.4 Definition of Terms. For the remainder of this AC, the following definitions of terms used will apply:
2.4.1 Maximum Payload Capacity. Refer to § 125.9, Definitions. If the maximum payload is determined to be 6,000 pounds or more, part 125 is applicable regardless of the number of seats.
2.4.2 Private Carriage. Private carriage is considered non-common carriage. Part 125 is applicable to large airplane operations in other than common carriage. Section 125.11(b) prohibits part 125 certificate holders from conducting any operation which results directly or indirectly from holding out to the general public.
2.4.3 Compensation or Hire. A term that originated with the regulation of ground transportation under the Interstate Commerce Act which was enacted in the late 1800s.
The test is presently contained in the definition of a “Commercial Operator” in 14 CFR part 1, § 1.1 and is essentially the same as the definition adopted in 1949 by the Civil Aeronautics Board.
2.4.4 Commercial Operator. Per § 1.1, a commercial operator is “a person who, for compensation or hire, engages in the carriage by aircraft in air commerce of persons or property, other than as an air carrier or foreign air carrier or under the authority of part 375 of this title. Where it is doubtful that an operation is for “compensation or hire,” the test applied is whether the carriage by air is merely incidental to the person’s other business or is, in itself, a major enterprise for profit.”
2.4.5 Common Carriage. A person is considered to be engaged in common carriage when holding out to the general public or to a segment of the public as willing to furnish transportation within the limits of its facilities to any person who wants it. Advertising through telephone yellow pages, billboards, television, radio, internet Web sites, social media, and individual ticketing are examples that have been legally found to be holding out.
2.4.6 Certificate Holders. One part 125 certificate shall be issued to any person. An operating certificate may not be held jointly by two or more persons. A partnership is considered a single person even though the partnership may consist of more than one individual or corporation. For example, where both a parent and a subsidiary corporation exist, only one of the two corporations may be the applicant for any one certificate and that certificate cannot be issued to, or in the name of, both corporations. Regardless of
2-3 common ownership, the parent and subsidiary corporation are considered by law as separate persons.
2.4.7 Deviations. At any point during certification, an applicant may request a deviation from any section of part 125 or an A125 Letter of Deviation Authority (LODA) authorizing a deviation from 14 CFR part 119, § 119.23(a)(3) and § 125.5 (the requirement to hold an operating certificate and operations specifications (OpSpecs)). (See Chapter 10 for further information.)
2.4.8 Applicant. An applicant is the entity applying for a part 125 operating certificate or any deviation authority. The applicant may be a part 125 certificate holder or an A125 LODA holder. An applicant may also be a person applying for a part 125 certificate or a person applying for a deviation from §§ 119.23(a)(3) and 125.5 (the requirement to hold an operating certificate and OpSpecs) hereafter to be identified as an A125 LODA holder.
2.4.9 A125 LODA Holder. An A125 LODA holder is a person/operator who is issued a LODA from §§ 119.23 and 125.5 (the requirement to hold an operating certificate and OpSpecs), and is identified in the Web-based Operations Safety System (WebOPSS) (referred to as “125M”) as an A125 LODA operator.
2.4.10 Letter of Deviation Authority (LODA). LODA is a formal authorization issued by the Federal Aviation Administration (FAA) certificate-holding district office (CHDO), authorizing a deviation from specified section(s) of part 125. The LODA is permitted by § 125.3. LODAs are issued to certificate holders and A125 LODA holders. LODAs are issued for operational uniqueness such as Special Flight Authorizations (SFA), intentional parachute operations, airplane museum operations, airplane leasing/manufacturer operations, and other individualized authorizations approved by the General Aviation and Commercial Division (AFS-800).
2.4.11 Special Flight Authorization (SFA). SFA is a LODA authorizing an operator to accomplish the following short-term operations (normally a maximum of 30 calendar-days) in accordance with part 91:
1. Sales demonstration flights when the operator is not certificated under part 119 or the holder of an A125 LODA.
2. Ferry flights when the operator is not certificated under part 119 or the holder of an A125 LODA.
3. Training flights conducted for certification under 14 CFR parts 61 and 63, associated with certification under part 119, or an applicant for an A125 LODA.
Note: SFAs (refer to § 91.715) are also issued to allow a foreign civil aircraft to be operated without a U.S. airworthiness certificate.
2.4.12 Standard Intentional Parachute Operations, Airplane Museum Operation, and Airplane Leasing/Manufacturer Operations Standard LODA. AFS-800 has considered the operational uniqueness of these operations and has determined that such operations,
2-4 conducted by airplanes with a seating configuration of 20 or more passengers or a maximum payload capacity of 6,000 pounds or more, should be authorized a deviation from § 125.1 applicability, and allowed to conduct all operations in accordance with part 91. AFS-800 has developed standard parachute, museum, and airplane leasing/manufacturer LODAs.
2.4.13 Special Flight Permits (SFP). SFPs are issued to the operator of an aircraft that may not currently meet the applicable airworthiness requirements but is capable of safe flight (refer to §§ 21.197 and § 21.199).
2.5 Is Part 125 Applicable to Your Operation?
2.5.1 Applicability. The applicability of this part is outlined in § 125.1.
2.5.2 Exceptions. The exceptions from applicability to part 125 are addressed in the following questions. Any person operating large airplanes who does not meet the criteria for one or more of the exceptions shown in the answers to these questions must make application for certification under part 125.
Note: The questions are arranged to correspond consecutively with those in the diagram in Figure 2-1, Test for Part 125 Applicability. Only the answers which result in exceptions to the applicability of part 125 are provided.
Question 1. Do you operate at least one civil airplane with a seating capacity of 20 or more passengers or a maximum payload capacity of 6,000 pounds or more?
If no, part 125 does not apply (refer to § 125.1(a)). If yes, move to question 2.
Question 2. Is your large airplane registered in the United States? If no, part 125 does not apply (refer to § 125.1(a)). If yes, move to question 3.
Question 3. Will your U.S.-registered, large airplane be operated in any portion of the United States or territory, commonwealth, or possession of the United States? If no, and you are not a U.S. citizen, you are only required to comply with the inspection program and maintenance requirements of § 125.247 (refer to § 125.1(c)). If yes, move to question 4. Foreign-based U.S. citizens also move to question 4.
Question 4. Is your U.S.-registered, large airplane operated on a restricted, limited, or provisional airworthiness certificate, SFP, or experimental certificate?
If yes, part 125 does not apply (refer to § 125.1(b)(2)). If no, move to question 5.
Question 5. Do you conduct intrastate common carriage as the holder of a commercial Air Carrier Certificate under the provisions of 14 CFR parts 121 or 135? The key is intrastate common carriage. If yes, then you must continue to operate under the commercial operator requirements of parts 121 or 135. If no, move to question 6.
2-5 Question 6. Do you presently hold an air carrier operating certificate issued under parts 121 or 135? If yes, then you are not eligible for a part 125 operating certificate (refer to § 125.11(a)). If no, move to question 7.
Question 7. Are your U.S.-registered, large airplane(s) presently required to be operated under parts 121, 135, or 137? If yes, part 125 does not apply (refer to § 125.1(b)(1)).

3-1 CHAPTER 3. PREPARING FOR CERTIFICATION
3.1 Scope and Contents. This chapter outlines the steps which should be considered in preparation for certification under 14 CFR part 125. It provides general guidance with references to other chapters in this advisory circular (AC) where more specific guidance is necessary. Examples of acceptable submissions are also referenced in this chapter.
3.2 Contacts with the FAA District Office. As the applicant, you are encouraged to make informal contact with your local Flight Standards District Office (FSDO) or International Field Office (IFO), as applicable, by telephone, email, or in person, after making a scheduled appointment, before proceeding with the development of the documents necessary for certification. It may be helpful to seek comments regarding the operations, maintenance, and avionics aspects of your operation at intermediate steps in the development of these documents. These informal contacts, and submissions of draft documents for their review, will assure the acceptability of the formal application and, in many cases, lessen the amount of time involved in the process of certification.
Note: References made to the FSDO in this document may also include the IFO, as applicable.
3.3 Time Constraints. Applicants are required to submit their complete formal application at least 60 calendar-days prior to the intended date of operation (refer to part 125, § 125.21).
This formal application must contain all items listed in paragraph 3.17.3. Your preparation of the formal application with its required attachments could, under normal circumstances, also take as much as 60 calendar-days. You should bear in mind the time involved for your preparation of the complete formal application package, and the 60-calendar-day period for FAA processing of that application, when planning the intended date for beginning operation under part 125.
3.4 Initial Informal Contact.
3.4.1 Contact the FAA. As soon as the decision is made to conduct operations with large airplanes and you have determined the planned operations will not fall under any of the exceptions to part 125 discussed in Chapter 2, paragraph 2.5.2, you should contact the local FSDO or IFO, as applicable. During this contact you will be able to discuss the scope of operations planned and get FAA input on the part 125 requirements that may be applicable to the planned operation.
3.4.2 FSDO/IFO Input. The district office or IFO, as applicable, will be able to give specific and timely input if you are prepared to supply in reasonable detail:
1. An outline of operations planned, including the number and type of airplane to be used;
2. A list of key management personnel who will represent the company during the certification process; and
3. An estimate of the dates on which you intend to make formal application for certification and plan to begin operations under part 125.
3-2
3.5 Timetable for Certification. At the initial informal meeting the FAA will review with you the steps necessary to develop the formal application and complete certification.
They will also assist you in determining the timetable you should meet in order to complete all aspects of preparing for, and completing, certification by the date you plan to begin operations under part 125.
3.6 Should You Submit a Request for Deviation Authority? After initial contact with the FSDO or IFO, as applicable, you should begin the process of deciding whether or not a deviation request from 14 CFR part 119, § 119.23(a)(3) and § 125.5 (the requirement to hold an operating certificate and operations specifications (OpSpecs)) will be required for your operation. You should consider early whether or not to submit a request for an A125 Letter of Deviation Authority (LODA) authority to deviate from certain sections of part 125. Chapter 10 outlines the procedures for making this request.
3.7 Determine How You Will Comply with Part 125.
3.7.1 Compliance Statement/Letter of Compliance. You will be required to submit a compliance statement/letter of compliance which summarizes, for each applicable part 125 section, how your organization intends to comply with part 125, and the applicable sections of 14 CFR parts 91 and 119.
3.7.2 Manual References. When developing the compliance statement/letter of compliance, a determination should be made of which sections of part 125 will be included in your Policy and Procedures Manual (PPM) to satisfy the type(s) of operations planned. In the compliance statement, your intentions should be specifically referenced as to the location in the manual of how you will otherwise assure compliance with the applicable sections.
3.8 Developing Company Manuals.
3.8.1 Manual’s Contents. After the operation planning has been completed, the next step would be the formulation of the policies and procedures that you want company personnel to follow in the performance of their duties. Part 125 requires these policies and procedures to be contained in a manual and specifies the required contents (refer to §§ 125.71,
125.73, and 125.249). Contents other than that required by the rule may be part of your PPM, as applicable to your operation.
3.8.2 Manual Formulation Guidance. Specific guidance on the formulation of this manual is included in Chapter 7 and Appendix A.
3.8.3 Approved Flight Manual. Section 125.75 requires that you have FAA-approved flight manuals for each airplane. Procedures should assure that these manuals are up-to-date and available to the crewmembers as required by § 125.71(e). Modifications to the operating procedures and performance data must be approved by the FAA (refer to § 125.75(b)).
3-3
3.9 Minimum Equipment List (MEL).
3.9.1 MEL Definition. An MEL is a method by which a part 125 holder can, under controlled conditions, operate an airplane with specified items of equipment inoperative until repairs are available or feasible. Authority for the use of an approved MEL is provided in § 125.201(a).
3.9.2 MEL Guidelines. Items of equipment required on an airplane may be dictated by the airplane type certificate, the operational requirements (e.g., part 125), or, in the case of optional equipment, by the operator. The MEL is developed by the operator from the Master Minimum Equipment List (MMEL). The MEL submitted by the operator may not be less restrictive than the MMEL from which it was developed, and provides for approval to deviate under controlled conditions from certain operational requirements.
These “controlled conditions” may be restrictions from flight during night, in instrument flight rules (IFR) or icing conditions, or by changes in in-flight operational procedures, temporary deactivation of components, or other procedures.
3.9.3 Approval of MEL. If you desire to use an MEL:
1. You should obtain a copy of the MMEL for your airplane. A copy of the MMEL can be obtained from the FAA’s Web site at http://fsims.faa.gov. If you do not have access to the internet, you can obtain a copy from your jurisdictional FSDO.
2. Section 125.201 authorizes flight with inoperative equipment under specific conditions.
3. An aviation safety inspector (ASI) may approve MELs for part 125 operators as part of the certification process.
4. You should submit your proposed MEL, as a separate document or as a section of your PPM, in your formal application for certification.
3.9.4 MEL Differences. Due to differences in operational factors (e.g., lack of maintenance bases), some options provided in the MMEL may not apply to part 125 certificate or A125 LODA holders. Each approved MEL will be tailored to the particular operator’s operations.
3.10 Maintenance Program.
3.10.1 Develop Maintenance Program. During your initial contacts with the FAA, and when developing the maintenance inspection program, you should follow the information provided in Chapter 9. It should be noted that a certificate holder under part 125 is not authorized by part 125 certification to perform preventive maintenance, rebuilding, or alteration. Such authority is not contained in part 43. This does not prevent an operator who holds a part 125 operating certificate from providing for its maintenance requirements by employing persons authorized to perform maintenance under part 43.
