Airworthiness Directive · Amendment 39-18457 · Nacelles/pylons
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2019-14-03. Comply with the one in force.
This AD applies to Airbus Model A318-111 and -112, airplanes; Model A319-111, -112, -113, -114, and -115 airplanes; Model A320-211, -212, and -214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes; certificated in any category; all manufacturer serial numbers on which Airbus Modification 33844 has been embodied in production.
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of cracking of the aft fixed fairing (AFF) of the pylons due to fatigue damage of the structure. This AD requires repetitive inspections for damage and cracking of the AFF of the pylons, and repair if necessary. We are issuing this AD to detect and correct damage and cracking of the AFF of the pylons, which could result in detachment of a pylon and consequent reduced structural integrity of the airplane.
At the later of times specified in paragraphs (g)(1) and (g)(2), or (g)(1) and (g)(3) of this AD, as applicable: Do a detailed inspection for damage and cracking of the AFF of the pylons, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-54-1027, dated April 10, 2014. Repeat the inspection thereafter at intervals not to exceed 2,500 flight cycles or 3,750 flight hours, whichever occurs first.
(1) For all airplanes: Before exceeding 5,000 flight cycles or 7,500 flight hours, whichever occurs first since the airplane's first flight.
(2) For airplanes on which the inspection specified in Airbus All Operators Transmission (AOT) A54N002-12 has been done as of the effective date of this AD: Within 2,500 flight cycles or 3,750 flight hours since the most recent accomplishment of maintenance planning data (MPD) Task ZL 371-01, or since doing the most recent inspection specified in Airbus AOT A54N002-12, whichever occurs first.
(3) For airplanes on which the inspection specified in Airbus AOT A54N002-12 has not been done as of the effective date of this AD: Within 750 flight cycles or 1,500 flight hours after the effective date of this AD, whichever occurs first.
If any crack is found during any inspection required by paragraph (g) of this AD: Before further flight, repair in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-54-1027, dated April 10, 2014. Accomplishment of this repair does not terminate the repetitive inspections required by paragraph (g) of this AD.
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.
