This memorandum clarifies the process outlined in FAA Order 8040.5, Airworthiness
Directive Process for Mandatory Continuing Airworthiness Information. Specifically,
paragraph 5a(1)(d) instructs the aviation safety engineer (ASE) to complete a No
Airworthiness Directive Required (NAR) if they determine there is no unsafe condition.
Further, appendix 1 states that the ASE complete the NAR form when they have
evaluated the mandatory continuing airworthiness information (MCAI) and decided not
to issue an airworthiness directive (AD).

This memorandum clarifies our acceptance procedures for TSO articles based on reciprocal agreements between the FAA and certain foreign CAAs. These acceptance procedures will eliminate past duplicative processes, reduce costs, and save time for both industry and the authorities involved.
The acceptance procedures allow the importing authority to accept the exporting authority’s approval of a TSO article without further evaluation or validation as stated in the bilateral agreement. This means the FAA can accept the TSO article design approval from a foreign CAA without issuing a letter of TSO design approval (LODA) as required by previous validation procedures.

This advisory circular (AC) describes an acceptable means for demonstrating compliance with
the requirements of title 14, Code of Federal Regulations (14 CFR) 33.70, Engine Life-Limited
Parts

This advisory circular (AC) provides ways for pilots and airplane operators to identify,
understand, and manage the risks associated with the landing phase of flight. It also provides
information that both certificated and noncertificated operators may use to develop personal or
standard operating procedures (SOP) to mitigate a runway excursion

The Boston Aircraft Certification Office Branch (ACOB) requested a deviation to FAA Order
8110.56B, Restricted Category Type Certification and FAA Order 8110.48A, How to Establish
the Certification Basis for Changed Aeronautical Products, for the Sikorsky S-70M, a derivative
of the U.S. Army UH-60M. The Boston ACOB requested relief from the requirement detailed in
Order 8110.56B, chapter 4, paragraph 9(b) and Order 8110.48A, paragraph 4-8.d, which state,
“The baseline certification basis for modifications is the 14 CFR regulations applicable to the
aircraft (i.e., part 23, part 25, part 27, part 29, or CARs, as appropriate) that were in effect on the
date that the first aircraft of the particular military model (i.e., MDS) was accepted for
operational use by the U.S. Armed Forces.” This memo corrects the deviation memo dated
3/28/23, from number AIR-620-23-DM02 to AIR-600-DM02.
