FAA proposes AD to replace mode control panels on Boeing 787s after uncommanded altitude changes

The FAA has proposed an airworthiness directive requiring operators to replace the mode control panel on Boeing 787 Dreamliners after reports of uncommanded altitude changes linked to the component. The directive targets a potential flight‑safety hazard and will impose fleet‑wide maintenance and supply demands on carriers.

What Hype is tracking

The FAA action addresses an in‑flight control anomaly with direct safety implications; it follows other recent 787 systems interventions such as the DGCA’s order to reinspect Ram Air Turbine systems after an uncommanded RAT deployment (https://hype.aero/?story=06a88aef-aa25-4a2d-8bef-32776436ae9f).
A fleet‑wide replacement AD will create immediate maintenance workloads and parts demand for operators and MROs, comparable to prior FAA mandates that required inspections on specific groups of 787s (119 U.S.‑operated 787s for oxygen‑mask inspections) (https://hype.aero/?story=4fb05f94-939b-435f-8646-9ed929b8c8eb).
The proposal sits within broader regulatory scrutiny of avionics and certification practices, reinforcing industry moves to revalidate flight‑deck components and software after a string of 787 and 737 avionics issues (see work on verifying flight‑deck component configurations and Boeing’s avionics overhaul) (https://hype.aero/?story=578128bb-1ab8-4c3e-ad9f-0a3bc81a9930, https://hype.aero/?story=9cf2057d-ce1f-4b4d-8a0e-a575b1b5a594).
