## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain transport category airplanes. That AD currently requires modification of the reinforced flight deck door. This proposed AD would expand the applicability of the existing AD and require other actions related to the reinforced flight deck door. These other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. This proposed AD is prompted by reports of discrepancies with the reinforced flight deck door. We are proposing this AD to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke or shrapnel, any of which could result in injury to the airplane flightcrew. This proposed AD would also find and fix wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.
