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 failures of the emergency slide on the forward passenger door, which prevented the door from opening. This proposed AD would require repetitive re-packing of certain forward door escape slides. We are proposing this AD to prevent failure of the emergency slide, preventing the forward passenger door from opening, which could result in impeded emergency evacuation and possible subsequent injury to passengers and flightcrew.
