 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. 2000-NM-104-AD; Amendment 39-11977; AD 2000-23-07]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule.
 SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300 and all Model A300-600 and A310 series airplanes, that currently requires performing a pitch trim system test to detect any continuity defect in the autotrim function, and follow-on corrective actions, if necessary. This amendment requires repetitive inspections of the autotrim function to detect such defects, and corrective actions, if necessary. This amendment also expands the applicability to include additional airplanes. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent a sudden change in pitch due to an out-of-trim condition combined with an autopilot disconnect, which could result in reduced controllability of the airplane.
 DATES: Effective December 20, 2000. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 20, 2000.
 ADDRESSES: The service information referenced in this AD may be obtained from Airbus Industrie, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France. This information may be examined at the Federal Aviation Administration (FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 2000-02-04, amendment 39-11522 (65 FR 3799, January 25, 2000), which is applicable to certain Airbus Model A300 and all Model A300-600 and A310 series airplanes, was published in the 
                    **Federal Register**
                     on June 12, 2000 (65 FR 36801). The action proposed to supersede AD 2000-02-04 to continue to require performing a pitch trim system test to detect any continuity defect in the autotrim function, and follow-on corrective actions, if necessary. The action also proposed to require repetitive inspections of the autotrim function to detect such defects, and corrective actions, if necessary. Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received. Request To Revise Applicability The manufacturer, Airbus, requests that the applicability of the proposed AD be revised to exclude Model A300-600 series airplanes on which Airbus Modification 12277 has been accomplished during production. In addition, since the issuance of the proposed AD, the Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, issued French airworthiness directive 2000-115-304(B) R2, dated July 12, 2000, as revised by Erratum, dated August 9, 2000, to exclude those airplanes from the applicability. The FAA concurs with the commenter's request, and has revised the applicability of this final rule accordingly. Request To Revise Reporting Requirement The Air Transport Association (ATA) of America, on behalf of one of its members, requests that the reporting requirement specified in the proposed AD be revised to require that inspection findings be reported to Airbus on a monthly basis, rather than 10 days following each inspection. The commenter states that since any necessary corrective actions would occur immediately as a result of the inspection findings, monthly reporting would not affect the safe operation of the airplane. For certain airlines, monthly reporting would greatly simplify the administrative tasks associated with ongoing reporting. The FAA concurs partially. The FAA agrees that corrective actions, if necessary, would be required prior to further flight; therefore, extension of the compliance time in question will not affect the safe operation of the airplane. However, the FAA considers that requiring report submittals on a monthly basis could lead to possible misinterpretation as to the specific deadline for submission of each report. In light of this, the FAA has revised the final rule to require submission of each report within 30 days after accomplishing each inspection (for inspections accomplished after the effective date of this AD), or within 30 days after the effective date of the AD (for inspections accomplished prior to the effective date of this AD). Operators are provided with additional time to 
                    ( print page 68877)
                    submit each report, and may choose to combine submittals of all reports for the past 30 days, which would reduce the administrative burden. Paragraph (b) of this AD has been revised accordingly. Conclusion After careful review of the available data, including the comments noted above, the FAA has determined that air safety and the public interest require the adoption of the rule with the changes previously described. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD. Interim Action This is considered to be interim action for Model A300-600 and A310 series airplanes. The manufacturer has advised that it currently is developing a modification that will positively address the unsafe condition addressed by this AD. Once this modification is developed, approved, and available, the FAA may consider additional rulemaking for these airplanes. Cost Impact There are approximately 120 airplanes of U.S. registry that will be affected by this AD. The inspection that is required by this AD will take approximately 1 work hour per airplane to accomplish, at an average labor rate of $60 per work hour. Based on these figures, the cost impact of the required action on U.S. operators is estimated to be $7,200, or $60 per airplane. The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. Regulatory Impact The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132. For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption
