Airworthiness Directive · Amendment 39-16989 · Fuselage
Airbus Airplanes
This AD applies to Airbus Model A340-211, -212, -311, and -312 airplanes; certificated in any category; having manufacturer serial numbers (MSN) 0002, 0003, 0005 through 0009 inclusive, 0011, 0013, 0014, 0015, 0018 through 0023 inclusive, 0025, 0026, and 0027.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A340-211, -212, -311, and -312 airplanes. This AD requires repetitive inspections for cracking at the fastener hole area just above stringer 28, of both left- and right-hand fuselage frame 39.1, and repair if necessary. This AD was prompted by a determination that certain airplanes were not included in a certain airworthiness limitation item (ALI) task (inspections for cracking of the fuselage frame 39.1) and that the inspections must be done to address the identified unsafe condition. We are issuing this AD to detect and correct cracking in the fuselage that could result in reduced structural integrity of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the later of the times specified in paragraphs (g)(1) or (g)(2) of this AD: Do an ultrasonic inspection for cracking at the fastener hole area just above stringer 28, of both left- and right-hand fuselage frame 39.1, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A340-53-4184, excluding Appendices 01 and 02, dated October 5, 2010. Repeat the inspection thereafter at intervals not to exceed 7,850 flight cycles or 53,300 flight hours, whichever occurs first.
(1) Before the accumulation of 13,600 total flight cycles or 92,100 total flight hours since the first flight of the airplane, whichever occurs first; or
(2) Within 6 months after the effective date of this AD.
If any cracking is found during any inspection required by paragraph (g) of this AD, before further flight, repair the crack using a method approved by Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or European Aviation Safety Agency (EASA) (or its delegated agent).
