## Abstract

We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-601, B4-603, B4-620, B4-605R, and B4-622R airplanes. This AD was prompted by a report that the door frame shells of passenger doors 2 and 4 may not have sufficient structural strength to enable the airplane to operate safely. This AD requires reinforcing the door frame shells of passenger doors 2 and 4 on both sides of the fuselage. We are issuing this AD to prevent structural failure of the door frame shells, which could result in in-flight decompression of the airplane and consequent injury to passengers.
