Summary
We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This proposed AD was prompted by reports of the cockpit door falling off the hinges when it is being open or closed. This proposed AD would require replacing the striker and quick-release pin of the passive lock of the cockpit door, and replacing the upper and lower hinges of the cockpit door. We are proposing this AD to prevent the cockpit door from falling off the hinges, which could cause injury to airplane occupants.
