ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of uncommanded altitude display changes in the mode control panel (MCP) altitude window. This AD requires replacing the existing MCP with a new MCP having a different part number. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 25, 2017. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 25, 2017.

SUPPLEMENTARY INFORMATION: [[Page 33783]] Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 777 airplanes. The NPRM published in the Federal Register on December 20, 2016 (81 FR 92740) (``the NPRM''). The NPRM was prompted by reports of uncommanded altitude display changes in the MCP altitude window. The NPRM proposed to require replacing the existing MCP with a new MCP having a different part number. We are issuing this AD to prevent uncommanded changes to the MCP selected at altitude; such uncommanded changes could result in incorrect spatial separation between airplanes, midair collision, or controlled flight into terrain. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Support for the NPRM Boeing and FedEx stated that they concur with the contents of the NPRM. Request To Reduce the Compliance Time Air Line Pilots Association, International (ALPA), indicated its support for the NPRM but requested that the compliance time in paragraph (g) of the proposed AD be reduced from 60 months to 50 months. The commenter did not provide justification for its request. We do not agree with the commenter's request to reduce the compliance time. In developing an appropriate compliance time, we considered the safety implications and the availability of required parts. In addition, we also received manufacturer concurrence for the 60-month compliance time. In consideration of all of these factors, we determined that the compliance time, as proposed, represents an appropriate interval in which the MCP parts can be replaced in a timely manner within the fleet, while still maintaining an adequate level of safety. For most ADs, operators are permitted to accomplish the requirements at a time earlier than the specified compliance time; for this AD, an operator may choose to replace the affected MCP at any time up to 60 months after the effective date of this AD. If additional data are presented that would justify a shorter compliance time, we might consider further rulemaking on this issue. We have not changed this AD in this regard. Request To Revise the Applicability United Airlines (UAL) requested that the applicability of the proposed AD be limited to only those MCP series parts on which the uncommanded changes in the speed/mach window occurred. The commenter noted that the NPRM did not indicate if the uncommanded changes were reported on all three MCP series parts (MCP-770, MCP-771, and MCP-770C) or only one MCP series part. The commenter suggested that if the uncommanded changes occurred only on one MCP series part, then the applicability of the proposed AD should be limited to that particular MCP series part. The commenter observed that this would reduce the number of MCP parts that need to be replaced or upgraded and reduce the compliance time needs. We agree that clarification is necessary regarding the affected MCP series parts. Based on the manufacturer's installation review, the unsafe condition has been identified to exist in all three MCP series parts. Therefore, no change to this AD is required regarding this issue. Request To Review the MCP Design One commenter, Geoffrey Barrance, noted that the FAA has issued AD 2016-25-01, Amendment 39-18727 (81 FR 94949, December 27, 2016), which addressed uncommanded autopilot engagement before takeoff. The commenter thought that there was a similarity in the root causes (malfunction of the MCP) of the unsafe conditions in AD 2016-25-01 and this final rule. The commenter recommended that the FAA initiate a review of the MCP design, including changes that might have been introduced over the life of these units, to identify if the design was initially susceptible to, or has been subsequently compromised in a way that could result in the unsafe conditions of both ADs. We infer the commenter may think the unsafe condition associated with AD 2016-25-01 resulted from a similar root cause as the unsafe condition addressed by this AD based on a statement in the Discussion section of the NPRM (80 FR 79735, December 23, 2015) associated with AD 2016-25-01. That statement noted that ``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.'' During the public comment period for the NPRM associated with AD 2016-25-01, Boeing stated that this statement was speculative and requested that the FAA remove it and replace it with a statement that possible failures in the autopilot flight director system can cause an uncommanded engagement of the autopilot. We agreed the replacement statement would be less speculative; however, because the Discussion section of an NPRM is not repeated in the final rule, AD 2016-25-01 was not revised. We do not agree with the commenter's request because we have determined that there is no similarity in the root cause of the unsafe condition of AD 2016-25-01 and this AD. The unsafe condition identified in AD 2016-25-01 is different from the unsafe condition identified in this final rule. AD 2016-25-01 addresses uncommanded autopilot engagement on the ground, potentially resulting in incorrect stabilizer trim adjustment during takeoff. This final rule addresses uncommanded altitude display changes in the MCP while the autopilot is engaged. We have not changed this AD regarding this issue. Requests To Revise the Estimated Costs of Compliance Cathay Pacific Airlines asked why operators are being charged for the parts and labor associated with compliance with the proposed AD if the unsafe condition is the result of a design flaw (the problematic MCP-770 part) that could not be detected during flight tests or the design phase. We infer that the commenter is requesting that either the estimated costs of the proposed AD be revised or the manufacturer's warranty coverage. We do not agree to revise the cost estimates. We do not control the manufacturer's warranty coverage. We have identified an unsafe condition that must be corrected to ensure that airplanes are operated in an airworthy condition, as required by the Federal Aviation Regulations. We have not changed this AD in regard to this issue. UAL requested a revision to the estimated costs of the proposed AD because the estimated costs provided are too low. UAL stated that only MCP-770C can be upgraded and all other MCP series parts would need to be replaced. UAL observed that its estimated fleet cost would exceed $8,000,000. We do not agree with the commenter's request. We acknowledge that the cost estimate does not include the cost of a new MCP. The estimated costs in the NPRM were based on data provided in Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016. The cost section of the NPRM indicated that we have received no definitive data regarding the cost of a new MCP. Although UAL provided a [[Page 33784]] cost estimate for its fleet, we still have not received a definitive cost estimate for a new MCP. We have not changed this AD regarding this issue. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016. The service information describes procedures for replacing the existing MCP part with a new MCP part having a different part number, in the glareshield in the flight compartment. 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. Costs of Compliance We estimate that this AD affects 203 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- Replacement.................. 2 work-hours x $85 Up to $5,800\1\. Up to $5,970... Up to $1,211,910.\1\ per hour = $170. ---------------------------------------------------------------------------------------------------------------- \1\ Since we have received no definitive data regarding the cost of a new MCP we have provided costs for the upgrade (modified part) only. 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 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), (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.
