Purpose of This Notice. This notice decommissions Operations Specification
(OpSpec) C300, 14 CFR Part 97 NDB, NDB/DME, VOR, VOR/DME, and TACAN Instrument
Approach Procedures Using Substitute Means of Navigation, and creates new OpSpec C085
(same title). The purpose of this change is to establish this OpSpec as a standard authorization.
This is a mandatory change for Title 14 of the Code of Federal Regulations (14 CFR) parts 121
and 135 certificate holders, including part 121/135 combination certificates. All OpSpec C300
templates will be decommissioned and in its place, certificate holders should be issued
OpSpec C085.

Purpose of This Notice. This notice provides additional instructions and guidance related to
Notice N 8900.464, OpSpec/MSpec/LOA A002, Definitions and Abbreviations, which expired
on April 25, 2019. N 8900.464 announced a nonmandatory revision to operations specification
(OpSpec)/management specification (MSpec)/Letter of Authorization (LOA) A002 and directed
the reissuance of A002 for affected operators under Title 14 of the Code of Federal Regulations
(14 CFR) parts 91 subpart K (part 91K), 121, 125, and 135, and part 125 Letter of Deviation
Authority (LODA) holders. The revision added a definition for “cargo” in support of an air cargo
safety initiative and aligned the Federal Aviation Administration’s (FAA) definition with the
International Civil Aviation Organization’s (ICAO) definition. This notice reemphasizes the
requirement to reissue A002 to affected operators and provides guidance for determining
whether the cargo definition may also necessitate the reissuance of an operator’s
OpSpec/MSpec/LOA A003, Aircraft Authorization, or require a change to the Vitals in the
Safety Assurance System (SAS).

This memorandum corrects and clarifies paragraph two of memorandum AIR600-19-
6C0-DM113, dated May 01 2019, regarding the primary audience. The initial memo
inadvertently omitted AFS maintenance designees (DAR-T). The primary audience is to
include all Flight Standards Service (AFS) designees (DAR-F and DAR-T) that issue
Airworthiness Certificates.
This memorandum authorizes a deviation from FAA Order 8130.2, Airworthiness
Certification of Aircraft, paragraph 2-3, Common Procedures for Issuing an
Airworthiness Certificate, and announces the implementation and authorizes the use of
the Aviation Safety Knowledge Management Environment (ASKME) Segment II,
electronic Airworthiness Certification (AWC) application. This application automates
the application and issuance of Airworthiness Certificates.

This order provides information and guidance to aviation safety
inspectors (ASI) regarding the applicability and enforcement of Original Equipment
Manufacturer’s (OEM) data listed on the Federal Aviation Administration’s (FAA) Type
Certificate Data Sheet (TCDS). Information and guidance are also provided regarding OEM maintenance manual material; Service Letters (SL) and Service Bulletins (SB); and other maintenance or flight operations information, including any material that has been identified or labeled by an OEM as “Mandatory.”

This AC provides guidance for
towbar and towbarless movement of aircraft and applies to all operators under Title 14 of
the Code of Federal Regulations (14 CFR) parts 91, 91 subpart K (part 91K), 121, 125,
129, and 135. The term “certificate holder (CH)” will be used throughout this document
to represent “operators,” “air carriers,” and their agents. 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, and
the document is intended only to provide information to the public regarding existing
requirements under the law or agency policies.

This final rule amends certain airworthiness regulations applicable to cabin pressurization systems and oxygen dispensing equipment on transport category airplanes, to facilitate certification of those airplanes, systems, and equipment for operation at high elevation airports. This rule eliminates the need for certain equivalent level of safety findings and exemptions.

The FAA is amending its standards for pressurized compartment loads such that partitions located adjacent to a decompression hole need not be designed to withstand a certain decompression condition. This rulemaking is necessary because, in some cases, it is not practical to design partitions in certain airplane compartments to withstand this decompression condition if it occurs within that compartment.
