Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by reports of deficiencies in the flight control module (FCM) software. This proposed AD would require installing certain FCM software. We are proposing this AD to correct deficiencies in the FCM software, which, if not corrected, could prevent continued safe flight and landing.
