Airworthiness Directive · Amendment 39-17460 · Fuselage
Airbus Airplanes
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-605R, and B4-622R airplanes; certificated in any category; all serial numbers.
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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Before the accumulation of 42,500 total flight cycles or within 2,000 flight cycles after the effective date of this AD, whichever occurs later: Do the actions specified in paragraph (g)(1) or (g)(2) of this AD, as applicable.
(1) For Model A300 B4-622R airplanes: Reinforce the door frame shells of passenger doors 2 and 4 on both sides of the fuselage, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6170, dated May 16, 2011.
(2) For Model A300 B4-601, B4-603, B4-620, and B4-605R airplanes: Reinforce the door frame shells of passenger doors 2 and 4 on both sides of the fuselage, using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA) (or its delegated agent).
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
