This notice provides information and guidance regarding the
relocation of guidance and policy within Federal Aviation Administration (FAA) Order 8900.1.
Specifically, content related to Required Inspection Items (RII) found in Order 8900.1,
Volume 3, Chapter 43, Section 2, Evaluating the Required Inspection Program, has been revised
and relocated to the new Volume 20, Chapter 6, Section 1, Evaluating Required Inspection Item
(RII) Procedures.

EPA Proposed Rule on Particulate Matter Emission Standards

The U.S. Environmental Protection Agency’s (EPA) has issued a proposed rule for particulate matter (PM) emission standards and test procedures for civil aircraft engines.  The proposed standards would apply to new type design and in-production civil aircraft engines with rated output of greater than 26.7 kilonewtons.  The proposed standards would align with International Civil Aviation Organization (ICAO) PM standards and would take effect on January 1, 2023.

ED Decision 2022/001/R Regular update of AMC-20 — AMC-20 Amendment 23

The objective of this Decision is to provide state-of-the-art means for showing compliance with the applicable airworthiness requirements with regard to the following:

  • EASA AMC 20-136 Aircraft electrical and electronic system lightning protection;
  • EASA AMC 20-158 Aircraft electrical and electronic system high-intensity radiated fields (HIRF) protection; and
  • EASA AMC 20-193 Use of multi-core processors (MCPs).

These amendments to AMC-20 are expected to facilitate the certification process while maintaining an adequate level of safety. They will also improve harmonisation with the equivalent FAA ACs.
Overall, they would have an economic and safety benefit, without any environmental or social impacts.

FAA Notice N8900_606 Use of Air Carrier Pilots During Flight Standardization Board Evaluations for Transport Airplanes

This notice provides information and guidance to the Aircraft
Evaluation Division (AED) (AFS-100) regarding the use of domestic and foreign air carrier
pilots during Flight Standardization Board (FSB) operational evaluations. Based on the
implementation of Section 128 of the Aircraft Certification, Safety, and Accountability Act
of 2021 (ACSAA), the FSB’s procedures must now include the use of air carrier pilots of
varying levels of experience for transport airplane type certification projects.

EASA ED Decision 2021/016/R Rotorcraft chip detection systems and Rotorcraft occupant safety in the event of a bird strike

The objectives of this Decision are to:

  • improve rotorcraft safety by ensuring that the chip detection systems that are installed in rotorcraft rotor drive systems achieve an acceptable minimum level of effectiveness in detecting the incipient degradation or failure of components of the rotor drive system; and
  • improve rotorcraft occupant safety in the event of a bird strike.

This Decision amends:

  • the Certification Specifications, Acceptable Means of Compliance and Guidance Material for Small Rotorcraft (CS-27) and the Certification Specifications, Acceptable Means of Compliance and Guidance Material for Large Rotorcraft (CS-29) to introduce:
    • certification specifications (CSs) for the effectiveness demonstration of chip detection systems; and
    • related acceptable means of compliance (AMC) and guidance material (GM);
  • CS-27 to introduce:
    • a design CS (CS 27.631 ‘Bird strike’) to ensure safe landing after a bird strike on the windshield of rotorcraft with six or more passenger seats; and
    • the related AMC to support the application of that CS; and
  • CS-29 to:
    • improve the wording of CS 29.631 ‘Bird strike’; and
    • introduce related AMC to support the application of that CS.

The amendments are expected to:

  • increase the safety of rotorcraft rotor drive systems by improving their designs; and
  • increase the safety of newly designed small-rotorcraft (CS-27) operations.

The amendments will have no significant economic impact, and no environmental or social impacts.
