This action adopts fuel efficiency requirements for certification of certain airplanes. These certification requirements implement the emissions standards adopted by the Environmental Protection Agency (EPA) to allow manufacturers to certificate their airplanes for fuel efficiency in the United States. This action also fulfills the FAA’s Clean Air Act obligations to enforce implementation of EPA’s aircraft emissions standards for greenhouse gas emissions.

NOTE: Inspectors assigned to process a Streamlined Part 91 Operational Approval Application should use the guidance in this section instead of the guidance typically used to process applications for individual Letters of Authorization (LOA). This guidance facilitates the streamlined process and enables inspectors of varying experience levels to issue the LOAs without policy division concurrence.

This notice announces changes to the requirements for issuing
operations specification (OpSpec) A050 and revises the templates for affected Title 14 of the
Code of Federal Regulations (14 CFR) part 135 operations, including part 135 operations
conducted under a combined 14 CFR part 121/135 certificate.

This notice announces a nonmandatory revision to operations
specification (OpSpec) A001 for Title 14 of the Code of Federal Regulations (14 CFR) part 129
to update the terminology used for the operations authorized. This notice also announces revised
Federal Aviation Administration (FAA) Order 8900.1 guidance for OpSpec A001.

This notice announces a revision to operations specification
(OpSpec) A001 for Title 14 of the Code of Federal Regulations (14 CFR) part 145 certificate
holders (CH) to accommodate multiple aviation safety agreements within the scope of this
OpSpec. It also simplifies the template language to provide verification of the safety agreements
in general by removing specific references to U.S./European Union (EU) aviation safety
agreements.

This notice provides information and guidance to principal
inspectors (PI) on reviewing and approving minimum equipment list (MEL) relief for added or
removed items due to a change to type design.

This memorandum addresses FAA compliance with Section 116(b) of the Aircraft
Certification, Safety, and Accountability Act, Pub. L. 116-260 (the Act). This
memorandum provides the framework and guidance for the FAA’s implementation of
Section 116(b) to Aircraft Certification Service staff involved in the certification of
transport category airplanes and transport rotorcraft.
This policy does not address compliance of specific aircraft models to Section 116(b).
Because every flightdeck design is different, assessments regarding compliance of
existing flightcrew alerting systems with Section 116(b) must be made on a case-by-case
basis as necessary during the design certification process for an amended type certificate.

This notice announces revisions to operations specifications
(OpSpecs), guidance, and training related to Title 14 of the Code of Federal Regulations
(14 CFR) part 147 certificated Aviation Maintenance Technician Schools (AMTS).
