Airbus Model A300 B2 and B4 Series Airplanes - 2006-NM-027-AD

Comment on [Docket No. FAA-2006-25670; Directorate Identifier 2006-NM-027-AD]RIN 2120-AA64 This proposed action requires work be accomplished pursuant to certain OEM and/or manufacturer service documents. The Modification and Replacement Parts Association (MARPA) submits the following comment: Frequently airworthiness directives are based upon service information originating with the type certificate holder or its suppliers. Manufacturer service documents are privately authored instruments generally enjoying copyright protection against duplication and distribution. When a service document is incorporated by reference pursuant to 5 U.S.C. 552(a) and 1 CFR part 51 into a public document such as an airworthiness directive, it loses its private, protected status and becomes itself a public document. If a service document is used as a mandatory element of compliance it should not simply be referenced, but should be incorporated into the regulatory document. Public laws by definition must be public which means they cannot rely for compliance upon private writings. Since the interpretation of a document is a question of law and not of fact, a service document not incorporated by reference will not be considered in a legal finding of the meaning of an airworthiness directive. We are therefore concerned that failure to incorporate essential service information could result in a court decision invalidating the airworthiness directive. Incorporated by reference service documents should be made available to the public by publication in the Document Management System (DMS) keyed to the action that incorporates them. The stated purpose of the incorporation by reference method of the Federal Register is brevity; to keep from expanding the Federal Register needlessly by publishing documents already in the hands of the affected individuals. Traditionally, "affected individuals" has meant aircraft owners and operators who are generally provided service information by the manufacturer. However, a new class of affected individuals has emerged since the majority of aircraft maintenance is now performed by specialty shops instead of aircraft owners and operators. This new class includes maintenance and repair organizations (MRO), component servicing and repair shops, parts purveyors and distributors and organizations manufacturing or servicing alternatively certified parts under 14 CFR § 21.303 (PMA). Further, distribution to owners may, when the owner is a financing or leasing institution, not actually reach the persons responsible for accomplishment of the airworthiness directive. We therefore request that the service documents deemed essential to the accomplishment of this proposed action be (1) Incorporated by reference into the regulatory instrument, and (2) published in the DMS.
