[Federal Register Volume 80, Number 246 (Wednesday, December 23, 2015)] [Proposed Rules] [Pages 79735-79738] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-32055] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-7525; Directorate Identifier 2015-NM-064-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400D, and 747-400F series airplanes; Model 757 airplanes; and Model 767 airplanes. This proposed AD was prompted by reports of uncommanded autopilot engagement events resulting in incorrect stabilizer trim adjustment during takeoff. This proposed AD would require, depending on the model/configuration for Model 747 airplanes, installing an on-ground stabilizer autotrim inhibit system, doing routine functional testing of the automatic stabilizer trim inhibit system and corrective actions if necessary; for Model 757 airplanes and Model 767 airplanes, installing relays and related wiring to open and close the flight control computer (FCC) analog output that controls the stabilizer trim adjustment, doing routine functional testing of the automatic stabilizer trim inhibit system, and corrective actions if necessary; and for Model 767-300, and -300F series airplanes, installing new operational program software (OPS) into the FCCs. We are proposing this AD to prevent stabilizer mistrim, which could result in a high-speed rejected takeoff and runway overrun, or reduced controllability of the airplane after takeoff due to insufficient pitch control. DATES: We must receive comments on this proposed AD by February 8, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

[[Page 79736]] Discussion We have received reports of uncommanded autopilot engagement events resulting in incorrect stabilizer trim adjustment during takeoff. The current configuration of affected airplanes allows engagement of the autopilot while on the ground. This engagement can result in the stabilizer trim being positioned to a trim setting outside of the acceptable takeoff setting range. The root cause is unknown, but the erroneous autopilot engage request is believed to have come from the mode control panel (MCP) and to have been caused by contamination within the MCP. Incorrect stabilizer trim adjustment during takeoff, if not corrected, could result in a high-speed rejected takeoff and runway overrun, or reduced controllability of the airplane after takeoff due to insufficient pitch control. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. Boeing Special Attention Service Bulletin 747-22-2256, dated March 6, 2015. This service information describes procedures for installing an on-ground stabilizer autotrim inhibit system, and doing functional testing. Boeing Special Attention Service Bulletin 757-22-0096, dated March 23, 2015. This service information describes procedures for modifying relays and wiring to open and close the FCC analog output that controls the stabilizer trim adjustment, and doing functional testing. Boeing Special Attention Service Bulletin 767-22-0143, Revision 1, dated July 6, 2015. This service information describes procedures for modifying relays and wiring to open and close the FCC analog output that controls the stabilizer trim adjustment, and doing functional testing. Boeing Special Attention Service Bulletin 767-22-0146, Revision 1, dated June 25, 2015. This service information describes procedures for installing new OPS into the FCCs. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. FAA's Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously. For information on the procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2015- 7525. Differences Between This Proposed AD and the Service Information For Model 747 airplanes, this proposed AD would require doing post- modification routine functional testing of the automatic stabilizer trim inhibit system, and corrective actions if necessary, at intervals not to exceed 1,500 flight hours. The service information does not require these actions. Explanation of ``RC'' Steps in Service Information The FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner's/operator's understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The steps identified as Required for Compliance (RC) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. For service information that contains steps that are labeled as RC, the following provisions apply: (1) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD, and an AMOC is required for any deviations to RC steps, including substeps and identified figures; and (2) steps not labeled as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition. Costs of Compliance We estimate that this proposed AD affects 1,220 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Model 747 series airplane 123 work-hours x $85 $2,714 $13,169........... $1,790,984. modification (136 airplanes). per hour = $10,455. Model 747 series airplane 4 work-hours x $85 per 0 $340 per test..... $46,240 per test. functional test (136 hour = $340. airplanes). Model 757 series airplane 83 work-hours x $85 per 3,236 $10,291........... $6,977,298. modification (678 airplanes). hour = $7,055. Model 757 series airplane 3 work-hours x $85 per 0 $255 per test..... $172,890 per test. functional test (678 hour = $255 per test. airplanes). Model 767 series airplane 121 work-hours x $85 6,076 $16,361........... $6,642,566. modification (406 airplanes). per hour = $10,285. Model 767 series airplane 1 work-hour x $85 per 0 $85............... $1,955. software modification (23 hour = $85. airplanes). Model 767 series airplane 5 work-hours x $85 per 0 $425 per test..... $172,550 per test. functional test (406 hour = $425 per test. airplanes). ---------------------------------------------------------------------------------------------------------------- [[Page 79737]] According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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 Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and (4) 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
