Examining the Docket
You may examine the airworthiness directive (AD) docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647-5227) is located on the plaza level of the Nassif Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Airbus Model A310 airplanes. That NPRM was published in the Federal Register on October 3, 2006 (71 FR 58320). That NPRM proposed to require doing repetitive inspections for any missing, damaged, or incorrectly installed wiper rings in the splined couplings of the flap transmissions shafts; inspections for any missing, damaged, or incorrectly installed rubber gaiters and straps on the sliding bearing/plunging joints of the flap transmission; and corrective action if necessary.
Comments
We provided the public the opportunity to participate in the development of this AD. We have considered the comments received.
Request To Revise Inspection Type
Airbus requests that the type of inspection specified in paragraph (f) of the NPRM be revised from general visual inspection to detailed inspection. The commenter states that calling the inspection a detailed inspection would be more relevant because cleaning of the work area is specified in the service bulletin referenced in paragraph (f) of the NPRM.
We agree with the commenter. We have revised this final rule to clarify that our intent is to require a detailed inspection. Additionally, we have added a note to the final rule to define that inspection.
Request To Incorporate Service Information
The Modification and Replacement of Parts Association (MARPA) states that typically airworthiness directives are based onservice information originating with the type certificate holder or its suppliers. MARPA also states that manufacturer's service documents are privately authored instruments generally enjoying copyright protection against duplication and distribution. MARPA contends that 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. MARPA explains that 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. MARPA states that public laws by definition must be public which means they cannot rely for compliance upon private writings. MARPA is concerned that failure to incorporate essential service information could result in a court decision invalidating the airworthiness directive.
MARPA also states that incorporation by reference service documents should be made available to the public by publication in the Docket Management System (DMS) keyed to the action that incorporates them. MARPA explains that 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. MARPA notes that traditionally, "affected individuals'' has meant aircraft owners and operators who are generally provided service information by the manufacturer. However, MARPA states that 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. MARPA states that this new class includes maintenance and repair organizations, component servicing and repair shops, parts purveyors and distributors and organizations manufacturing or servicing alternatively certifiedparts under section 21.303 ("Replacement and modification parts'') of the Federal Aviation Regulations (14 CFR 21.303). Further, MARPA states that the concept of brevity is now nearly archaic as documents exist more frequently in electronic format than on paper.
We understand MARPA's comment concerning incorporation by reference. The Office of the Federal Register (OFR) requires that documents that are necessary to accomplish the requirements of the AD be incorporated by reference during the final rule phase of rulemaking. This final rule incorporates by reference the document necessary for the accomplishment of the requirements mandated by this AD. Further, we point out that while documents that are incorporated by reference do become public information, they do not lose their copyright protection. For that reason, we advise the public to contact the manufacturer to obtain copies of the referenced service information.
In regard to the commenter's request to post service bulletins on the Department of Transportation's DMS, we are currently in the process of reviewing issues surrounding the posting of service bulletins on the DMS as part of an AD docket. Once we have thoroughly examined all aspects of this issue and have made a final determination, we will consider whether our current practice needs to be revised. No change to the final rule is necessary in response to this comment.
Conclusion
We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, "General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory FindingsWe have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a "significant regulatory action'' under Executive Order 12866;
(2) Is not a "significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
