The Automatic Dependent Surveillance – Broadcast (ADS-B) Out rule takes effect on January 1,
2020. After this date, and unless otherwise authorized by ATC, no person may operate an
aircraft in Class A airspace or other airspace as listed in Title 14 Code ofFederal Regulations (14
CFR) part 91.225, unless the aircraft has equipment installed that meets the performance
requirements in TSO-C166b or TSO-C154c. The ADS-BOut equipment performance
requirement listed in 14 CFR 91.227(c)(1)(ii) states the aircraft’s Navigation Accuracy Category
for Velocity (NACv) must be less than 10 meters per second.
Guidance from AC 20-165B, Airworthiness Approval of Automatic Dependent Surveillance Broadcast
OUT (dated 1217/15), paragraph 3.3.3.7.3, states: A NACv = 3 or NACv = 4 should
not be set based on GNSS velocity accuracy unless you can demonstrate to the FAA that the
velocity accuracy actually meets the requirement. Furthermore, in Appendix B, paragraph
B.4.14.3, NACV = 3 or 4, states: No standard for performance has been developed to support
NACv = 3 or NACV = 4. A NACv = 3 or NACv = 4 should not be set based on GNSS velocity
accuracy unless you can demonstrate to the FAA that the error contributions have been
adequately modeled to meet those levels of performance.

This advisory circular (AC) provides information to Title 14 of the Code of Federal Regulations (14 CFR) fractional ownership program managers operating under 14 CFR part 91 subpart K (part 91K) and 14 CFR part 119 certificate holders operating under 14 CFR parts 121 and 135, seeking approval of Operations Specification (OpSpec)/Management Specification (MSpec) A063, Flightcrew Member Certificate Verification Plan. An approved certificate verification plan allows part 91K program managers and part 119 certificate holders operating under parts 121 and 135 to provide a temporary verification document to flightcrew members whose airman or medical certificates have been lost, stolen, or destroyed, or are otherwise missing. Please note that this AC is associated with the Sample OpSpec/MSpec A063 Templates document that is posted for review on the Draft OpSpecs/Management Specifications/Letters of Authorization page.

This policy statement identifies applicable structural requirements and acceptable means of
compliance for certification of external modifications, such as antennas, radomes, cameras, and
external stores, on transport category airplanes.

This order provides guidance to FAA personnel responsible for evaluating aircraft wreckage and
classifying an aircraft as destroyed or scrapped. This order also provides guidance related to
actions that are required to be taken when an aircraft is determined to be destroyed or scrapped.
Such actions include the disposition of aircraft identification plates, aircraft de-registration, and
compliance with aircraft recordkeeping requirements. It addresses the re-registration of aircraft
that may have previously been classified as destroyed or scrapped and describes the procedures a
person may use to dispute a determination that an aircraft has been destroyed or scrapped.
Many current FAA and National Transportation Safety Board (NTSB) forms classify aircraft
damage as minor, major, substantial, or indicate that an aircraft has been destroyed. Title 14 of
the Code of Federal Regulations (14 CFR) § 47.41a(2) specifies that an aircraft’s Certificate of
Registration, AC Form 8050-3, is no longer effective if the aircraft is “totally destroyed or
scrapped.” In this order, we consider the report of a “destroyed aircraft” the same as an aircraft
reported as “totally destroyed.”
This order provides instructions for FAA employees to assist aircraft owners in complying with
the requirements of 14 CFR §§ 45.13 and 47.41 by specifying what constitutes a destroyed or
scrapped aircraft and by establishing procedures to properly disposition aircraft wreckage.
This order also sets forth a process for a person to dispute a determination that an aircraft has been
destroyed or scrapped.
