In a Notice of availability and request for public comment published in the Federal Register on August 25, 2004, the FAA is seeking comments on its proposed revision to Order 8110.42, Parts Manufacturer Approval Procedures. A copy of the proposed order is available from the FAA online here. Order 8110.42 provides “procedures for the evaluation and approval of replacement and modification parts for use on type-certificated products”.
According to the FAA, “the draft order clarifies policy, language and simplifies format”. It is not intended to change policy. However, the draft order includes “examples, expands on the test and computation method and provides more guidance on reverse engineering”. It also contains new appendices relating to roles of Designated Engineering Representatives in the design approval process, appendices that list the varied uses of “critical” in the context of aircraft parts, and appendices that provide guidance on statistical sampling in a quality system.
Comments to the proposed order may be sent via U.S. Mail to: Federal Aviation Administration, Aircraft Certification Service, Aircraft Engineering Division, Room 815, 800 Independence Avenue, SW., Washington, DC 20591. ATTN: John Milewski, AIR-110; personally delivered to: Federal Aviation Administration, Room 815, 800 Independence Avenue, SW., Washington, DC, 20591; or sent electronically with the title of the document: “Comments FAA Order 8110.42, Parts Manufacturer Approval Procedures”.
