This advisory circular (AC) provides the means for conducting IFPV of satellite-enabled PBN instrument flight procedures for both fixed-wing and helicopter aircraft. It also addresses validation of helicopter Wide Area Augmentation System (WAAS) special IFPs. This AC describes ground validation, pre-flight validation (including simulator evaluation and obstacle assessment), and flight validation.
The contents of this document do not have the force and effect of law and are not meant to bind the public in any way. This document is intended only to provide clarity to the public regarding existing requirements under the law or agency policies. Please note that, non-FAA service providers are not required to perform IFPV of PBN IFPs. If a non-FAA service provider chooses to perform IFPV of PBN IFPs, however, this AC provides the directions for doing so.

This memorandum authorizes a deviation from FAA Order 8000.95, Designee
Management Policy, Volume 8, Table 8-1, Minimum Qualification Requirements.
In the Amateur-Built and Light-Sport Aircraft (LSA) Certification block (on pages 8-11
and 8-12), under “Light-Sport Category Specialized Experience (LSA)”, paragraph c,
experience as a Designated Airworthiness Representative (DAR) is now included in the
minimum qualification requirements.

This notice provides guidance and information to aviation safety
inspectors (ASI) responsible for Title 14 of the Code of Federal Regulations (14 CFR) part 135
certificate holders (CH) that operate passenger-carrying, single-engine aircraft under instrument
flight rules (IFR). The information contained in this notice will assist ASIs in determining if
single-engine aircraft comply with the gyroscopic-instrument energy-source requirements to
conduct IFR passenger-carrying operations under part 135, § 135.163(h).

This memorandum authorizes a deviation from FAA Order 8130.2J, Airworthiness
Certification of Aircraft, Chapter 2, paragraph 2-4(c), which prescribes the procedures for
the replacement of airworthiness certificates and certification package corrections.
This deviation authorizes changes to the procedures for a “replacement” airworthiness
certificate, due to inaccurate and/or erroneous information, and removes the requirement
to apply for a replacement certificate, under certain circumstances. If the previous
airworthiness certification file was submitted to the FAA Registry within a six-month
period, the FAA office or designee assigned to the certification activity may make the
necessary corrections, and resubmit to the Registry, as necessary

This memorandum authorizes a deviation from FAA Order 8150.1D, Technical Standard Order
Authorization, paragraph 7-4, Note 1. The purpose of this memorandum is to facilitate the
Compliance and Airworthiness Division (AIR-700) to reuse previously approved deviations to
technical standard order (TSO) minimum performance standards for new technical standard
order authorization (TSOA) applications from the same applicant.

This order amends and expands the prior designation of information
received by the Federal Aviation Administration (FAA) from an Aviation Safety Action Program
(ASAP) as protected from public disclosure in accordance with the provisions of Title 14 of the
Code of Federal Regulations (14 CFR) part 193.

The FAA has recently adopted the attached AD for turbocharged, reciprocating engine powered airplanes and helicopters and turbocharged reciprocating engines with a certain v-band coupling installed.  This AD was prompted by multiple failures of spot-welded, multi-segment v-band couplings at the tailpipe to the turbocharger exhaust housing flange.  This AD establishes a life limit for the spot-welded, multi-segment exhaust tailpipe v-band coupling and requires repetitively inspecting the spot-welded, multi-segment exhaust tailpipe v-band coupling.
