WASHINGTON-<\/strong> Airlines operating Boeing 787 jets<\/a> from the US Hubs are being asked to replace mode control panels (MCP) following reports of uncommanded altitude changes.<\/p>\n\n\n\n

The Federal Aviation Administration (FAA)<\/a> has proposed critical safety directives affecting Boeing 787 aircraft operating in the United States. The directive is aimed at preventing potential controlled flight incidents.<\/p>\n\n\n\n

FAA Proposes 787 Safety Fixes<\/h2>\n\n\n\n

Boeing 787s that are being operated from hubs such as Seattle-Tacoma International Airport (SEA) and Boston Logan International Airport (BOS)<\/a> are one aircraft types to have received the directives.<\/p>\n\n\n\n

The FAA\u2019s proposed airworthiness directive for the Boeing 787 covers all U.S.-registered variants, including -8, -9, and -10 models, totaling 165 aircraft, reported Flight Global. <\/p>\n\n\n\n

Reports indicate the MCP, manufactured by Honeywell, can cause uncommanded changes to the selected altitude due to software malfunctions and electrical power irregularities.<\/p>\n\n\n\n

Operators are required to follow Boeing\u2019s April service bulletin to replace the faulty panels. Failure to comply could result in controlled flight into terrain or traffic conflicts. <\/p>\n\n\n\n

The FAA estimates the replacement cost at $405,000<\/strong> per aircraft, although Honeywell may cover part of this expense under warranty. Public feedback on the proposal is open for 45 days following 17 November.<\/p>\n\n\n\n

777 Landing Gear Recall<\/h2>\n\n\n\n

Similarly, Boeing 777 operators must replace main landing gear pumps after a wheel well fire raised safety concerns.<\/p>\n\n\n\n

The Boeing 777 fleet, comprising 340 U.S.-registered jets, faces a separate FAA directive after a wheel well fire caused by an overheating alternating current motor pump (ACMP). <\/p>\n\n\n\n

Investigations revealed a missing lock washer and nut in the electrical load control unit, which allowed two-phase power to reach the pump, leading to overheating and hydraulic fluid leakage.<\/p>\n\n\n\n

Boeing issued a service bulletin on 11 September recommending operators inspect records and replace ACMPs with modified pumps that include fusible links to prevent future overheating. <\/p>\n\n\n\n

The FAA requires airlines to follow these procedures to ensure flight safety. Comments on this proposed rule are also being accepted from the public.<\/p>\n\n\n\n

Industry Impact<\/h2>\n\n\n\n

These directives reflect growing attention to both electronic and mechanical safety systems in commercial aviation. <\/p>\n\n\n\n

Airlines must act swiftly to implement repairs to avoid potential incidents and comply with regulatory requirements. <\/p>\n\n\n\n

While costs are significant, the directives aim to protect passengers, crews, and the broader aviation network from preventable hazards.<\/p>\n\n\n\n

Bottom Line<\/h2>\n\n\n\n

The FAA\u2019s twin directives targeting the Boeing 787 and 777 fleets highlight the importance of proactive maintenance and regulatory oversight. <\/p>\n\n\n\n

By replacing faulty MCPs and ACMPs, operators reduce risks of altitude errors and wheel well fires, enhancing overall flight safety. <\/p>\n\n\n\n

Both directives remain open for public comment, giving industry stakeholders a chance to provide input before final rules are enacted.<\/p>\n\n\n\n
