[Federal Register Volume 63, Number 186 (Friday, September 25, 1998)] [Rules and Regulations] [Pages 51275-51277] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 98-25472] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. 97-NM-42-AD; Amendment 39-10796; AD 98-20-29] RIN 2120-AA64 Airworthiness Directives; Airbus Industrie Model A320 Series Airplanes AGENCY: Federal Aviation Administration, DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Industrie Model A320 series airplanes, that currently requires a revision to the Airplane Flight Manual (AFM) to prohibit automatic landings in configuration 3 (CONF 3). This amendment limits the applicability of the existing AD, and adds a new revision to the AFM to indicate that automatic landings in CONF 3 are prohibited and to specify an [[Page 51276]] increased minimum runway visual range for airplanes on which certain modifications have not been accomplished. This amendment also requires eventual replacement of the existing spoiler elevator computers with improved parts, and insertion of new pages into the AFM that correct landing distances required for automatic landings in CONF 3. 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 pitch-up of the airplane due to activation of the spoilers during an automatic landing, which, if not corrected, could result in tail strikes and structural damage to the airplane. DATES: Effective October 30, 1998. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of October 30, 1998. 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. FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-2110; fax (425) 227-1149. SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 92-19-13, amendment 39-8371 (57 FR 40601, September 4, 1992), which is applicable to all Airbus Industrie Model A320 series airplanes, was published in the Federal Register on July 23, 1998 (63 FR 39540). The action proposed to continue to require a revision to the Airplane Flight Manual (AFM) to prohibit automatic landings in configuration 3 (CONF 3). The action also proposed to limit the applicability of the existing AD, and add a new revision to the AFM to indicate that automatic landings in CONF 3 are prohibited and to specify an increased minimum runway visual range for airplanes on which certain modifications have not been accomplished. The action also proposed to require eventual replacement of the existing spoiler elevator computers with improved parts, and insertion of new pages into the AFM that correct landing distances required for automatic landings in CONF 3. 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. The commenters support the proposed rule. 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 as proposed. Cost Impact There are approximately 93 airplanes of U.S. registry that will be affected by this AD. The incorporation of the temporary revision into the AFM that is currently required by AD 92-19-13, and retained in this AD, takes 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 this requirement of this AD on U.S. operators is estimated to be $5,580, or $60 per airplane. The incorporation of the new temporary revision into the AFM that is required in 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 this requirement of this AD on U.S. operators is estimated to be $5,580, or $60 per airplane. The replacement of the spoiler elevator computers (SEC's) that is required in this AD action will take approximately 3 work hours per airplane to accomplish, at an average labor rate of $60 per work hour. Required parts will be provided by the manufacturer at no cost to the operators. Based on these figures, the cost impact of this requirement of this AD on U.S. operators is estimated to be $16,740, or $180 per airplane. The incorporation of AFM Section 5.06.00, pages 06 and 6A, into the AFM that is required in this AD action 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 this requirement of this AD on U.S. operators is estimated to be $5,580, or $60 per airplane. The cost impact figures discussed above are 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 substantial direct effects 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, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment. 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 ADDRESSES.
