This memorandum provides instructions on how ODA unit members must document compliance
to the 14 CFR part 23.

The FAAs temporary Limited Manufacturing Designated Airworthiness Representative (L-DARF)
program established by memos AIR-100-16-160-PM13 and AIR-600-17-6F0-PM01 will end
on September 30, 2018. In preparation for ending the program, this memorandum describes the
process by which existing L-DAR-F designees can be appointed with Function Code 19
delegation privileges as a Designated Airworthiness Representative – Manufacturing (DAR-F),
per FAA Order 8000.95, Designee Management Policy, Volume 1, Chapter 2, and Volume 8,
Chapter 2. This delegation will come with a specific limitation for issuing domestic
airworthiness approvals at their associated distributor location. DAR-F’s with function code 19
are not subject to the L-DAR-F date limitation that only allows Authorized Release Certificate,
FAA Form 8130-3, Airworthiness Approval Tags to be issued for new parts and articles that were
in the distributor’s inventory prior to November 1, 2016.

This deviation changes the initial training requirements required by FAA Order 8000.372A for new
appointments. Order 8000.372A, Chapter 7, paragraphs 701(a) and (b) refer to on-line training that
is no longer required. The required information in the two courses referenced is now included in
the UAS Certification Seminar required by paragraph 703. This seminar is scheduled through the
Manufacturing Inspection District Office.

This advisory circular (AC) provides information for certificated pilots who wish to maintain currency and flight instructors for flight reviews required by Title 14 of the Code of Federal Regulations (14 CFR) part 61, § 61.56 and the recent flight experience requirements of § 61.57.

This advisory circular (AC) provides guidance for developing and maintaining a reliability program as part of a Continuous Airworthiness Maintenance Program (CAMP). This AC incorporates the latest philosophy used by manufacturers when developing an aircraft’s initial maintenance schedule. An industry working group developed recommendations for a revised AC, which had not been updated since 1974. This AC revision addresses those recommendations.

This change updates and reorganizes the information in the advisory circular (AC) to provide procedures for the installation, maintenance, and inspection of emergency locator transmitter (ELT) systems. It also changes the title (formerly Operational and Maintenance Practices for Emergency Locator Transmitters and Receivers).

This AC describes an acceptable method, but not the only method, that may be used to demonstrate compliance to the propeller type certification requirements of Title 14, Code of Federal Regulations (14 CFR) 35.
