(b) Airworthiness Directives. Regardless of the type of airworthiness certificate being requested, you should review this block and indicate the aircraft is in compliance with all applicable ADs (refer to 14 CFR part 39, Airworthiness Directives, and 14 CFR § 21.99, Required design changes).

1 If all ADs are in compliance, you should check the box and then enter the latest AD biweekly supplement number published as of the date of application. You should use a four-digit year, a dash, and publication number format (for example, “2010-04”). As an example, if the day of your application is 11/28/2010, you would find 2010-24 as the latest supplement published on 11/23/2010. You would then enter “2010-24” in the block.

2 For a special airworthiness certificate in the light-sport category or the experimental category operating light-sport, you should list all applicable manufacturer safety directives available as of the date of application (for example, “SD-001”). If there are no manufacturer safety directives, “None” should be entered. This block should also contain the latest AD biweekly supplement and either the manufacturer’s list of safety directives or “None” (for example, “2010-04, SD-001, SD-002” or “2010-04, None”).

3 Each AD contains an applicability statement specifying the product (aircraft, aircraft engine, propeller, or appliance) to which it applies. Unless stated otherwise ADs only apply to type-certificated aircraft, including ADs issued for an engine, propeller, or appliance (refer to AC 39-7, Airworthiness Directives).

(c) Aircraft Listing. Older aircraft (predating TCDS) may have been originally certificated with aircraft specifications. This block should contain the page number of aircraft specification where the type or model is found. For example, a 1928 Travel Air 3000 has an aircraft specification of #31, where the aircraft type is listed on page 65 of that specification. If applicable, you should mark the box and enter the listing page number(s) as appropriate. If this block does not apply or there is no aircraft listing, you should leave the box unmarked and enter “N/A.”

(d) Supplemental Type Certificate. This block is applicable for all standard airworthiness certifications. This block is also applicable for special airworthiness certifications in the restricted, limited, provisional, and primary categories. When one or more STCs are installed, you should mark the box and complete the block with the required information. When no STCs are installed, you should leave the box unmarked and the block blank.

1 You should enter the STC number of each STC installed. If more space is needed, you should use an attachment. When using an attachment, you should list the STCs installed by STC number only. For aircraft involved in FAA STC projects, ensure the STC number for the completed project is listed in the block at the time of application.

2 For a special airworthiness certificate in the experimental or light-sport category, you should leave the box unmarked and enter “N/A” in the block.

(3) Item C, Aircraft Operation and Maintenance Records.

(a) Check if Records Are in Compliance with 14 CFR § 91.417, Maintenance Records. Your maintenance records must comply with 14 CFR § 91.417 and be in the English language. This block is applicable to all aircraft and should be marked to indicate the recordkeeping requirements of the regulation have been met.

1 Compliance to 14 CFR § 91.417(a)(2)(i) requires the total service time of the airframe, each engine, propeller, and rotor.

2 Compliance to 14 CFR § 91.417(a)(2)(ii) requires a maintenance record of the current status of life-limited parts of each airframe, engine, propeller, rotor, and appliance.

(b) Total Airframe Hours. You should enter into this block the aircraft’s total time in service measured in hours. Time in service should be determined from your aircraft and maintenance records.

(c) Experimental Only.

1 This block should only be completed when— (aa) You are submitting an application for a new or renewed special airworthiness certificate in the experimental category (experimental certificate), (bb) You are requesting a change from an experimental certificate back to a previously held standard airworthiness certificate, or (cc) You are requesting a change from an experimental certificate back to a previously held special airworthiness certificate in another category.

2 You should enter “0” if you are applying for an original issuance of an experimental certificate with zero hours flown.

3 If you are renewing an experimental certificate or making an application to change back a previously held certificate, you should enter in this block the number of hours the aircraft has flown since the issue of your current experimental certificate.

(4) Item D, Certification. You will need to read and verify the certification statement on the application before completing this item. There are three blocks to complete:

(a) Date of Application. You should enter the date that you attest to the certification statement in month/day/year format (for example, “02/09/2010”).

(c) Signature. The person whose name appears in the “Name and Title” block should sign the signature block.

d. Section IV, Inspection Agency Verification. You should only complete this section for standard airworthiness applications of used aircraft or surplus U.S. military aircraft.

To qualify for a standard airworthiness certificate, you must show the aircraft conforms to a type design approved under a TC or an STC. All applicable ADs must also be in compliance.

The aircraft must be inspected and found airworthy by one of four methods (refer to paragraph (1)(a) through (1)(d) of this section). Finally, the responsible person at the inspection agency will date and sign this block (refer to 14 CFR § 21.183(d), Used aircraft and surplus aircraft of the U.S. Armed Forces).

(1) Boxes. You should mark the applicable box and provide a certificate number or aircraft manufacturer name or firm in the corresponding block.

(a) 14 CFR part 121 Certificate Holder. You should mark this box and enter the certificate number (block 2) when the aircraft has been inspected and found airworthy by a part 121 certificate holder.

(b) Certificated Mechanic. You should mark this box and enter the certificate number (block 3) when the aircraft has been inspected and found airworthy by a certificated mechanic.

(c) Certificated Repair Station. You should mark this box and enter the certificate number (block 6) when the aircraft has been inspected and found airworthy by a mechanic at a certificated repair station. In the case of used aircraft and surplus aircraft of the U.S. Armed Forces, the FAA may accept a previously performed inspection in lieu of a 100-hour inspection. In this circumstance the applicant should list the foreign repair station name and number (if applicable) in block 6. Using permanent blue or black ink, the applicant should strike/draw a line through the title of block 5, initial the line-through, and provide a statement in block 5 that an equivalent inspection was performed.

(b) Type Certificate. You should mark this box if this aircraft was produced under a TC and not a PC.

(c) Other. This box should not be marked.

(3) Item C.

(a) Give Quantity of Certificates Required for Operating Needs. For manufacturers in serial production (except LSA manufacturers), you may request more than one certificate per application submitted. You should enter the quantity (in digits) of certificates needed for your operation. For example, entering “4” requests four certificates for use during production flight tests that can be transferred from one aircraft to another. However, for LSA production flight tests, permits are not transferable. Because each LSA is individually issued a special flight permit, you should enter “1” for one certificate.

(b) Date of Application. You should enter the current date as the special flight permit application date in the month/day/year format (for example, “02/09/2010”).

(c) Name and Title. You should either print or type the full name and title. A full name usually includes first name, a middle initial, and last name. Titles may include owner, president, director, or authorized agent. “John E. Doe, Owner” and “John Doe, Director of Quality Assurance” are some examples of a full name and title.

(d) Signature. The person whose name appears in the “Name and Title” block should sign this block.

g. Section VII, Special Flight Permit Purposes Other than Production Flight Test.

(1) Item A, Description of Aircraft. Entries in this section should match the data recorded on the aircraft’s registration certificate and the aircraft’s ID plate as applicable.

(c) To. You should enter the aircraft’s intended destination (for example, “Dallas, Texas”, or the airport identifier “DFW”).

(d) Via. This block should contain the name(s) of an airport or city at some intermediate point(s) in the flight. Entering “via” points provides a general direction of the flight route (refer to 14 CFR § 21.199(a)(2), Issue of special flight permits). For example, a flight from “Kansas City, Missouri” (or “MCI”), to “Dallas, Texas” (or “DFW”), may be flown via “Wichita, Kansas” (or “ICT”), and “Oklahoma City, Oklahoma” (or “OKC”). You should leave this block blank if there are no planned intermediate points.

(e) Departure Date. You should enter the date the flight is planned using month/day/year format (for example, “02/09/2010”).

(4) Item D, The Aircraft Does Not Meet the Applicable Airworthiness Requirements as Follows. In the space provided, you should detail the conditions where the aircraft does not comply with the applicable airworthiness requirements. You should keep in mind this is your basis for requesting a special flight permit and will need to be specific (refer to 14 CFR § 21.199(a)(4)).

(5) Item E, The Following Restrictions Are Considered Necessary for Safe Operation. In the space provided, you should write any restrictions you consider necessary for safe operation of the aircraft (for example, reduced airspeed, operating weight, turbulence avoidance, crew limitations, or qualifications). The application will be reviewed and additional conditions and/or limitations may be prescribed for safe operation (refer to 14 CFR § 21.199(a)(5) and (6)).

(6) Item F, Certification. If this section applies to your application, you should read the certification statement and verify that you meet the requirements before completing this item.

There are three blocks to complete:

(a) Date of Application. In this block, you should enter the current date using month/day/year format (for example, “02/09/2010”).
