Airworthiness Directive · Amendment 39-18144 · Wings
Airbus Airplanes
This AD applies to Airbus Model A319-115, A319-132, A319-133, A320-214, A320-232, and A320-233 airplanes, certificated in any category, manufacturer serial numbers (MSN) 5817, 5826, 5837, 5848, 5855, 5864, 5875, 5886, 5896, 5910, and 5918 and subsequent.
We are superseding Airworthiness Directive (AD) 2014-26-53 and AD 2015-03-02 for certain Airbus Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. AD 2014-26-53 required repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard main landing gear (MLG) support rib lower flange location fasteners and, depending on findings, accomplishment of applicable corrective action(s). AD 2015-03-02 required repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. This new AD retains the repetitive detailed visual inspections to detect discrepancies of the fasteners located in the wing lower skin surface and inboard MLG support rib lower flange with extended compliance times and repetitive intervals, and accomplishment of applicable corrective actions. This new AD also retains the repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. In addition, this new AD adds airplanes to the applicability. This AD was prompted by a determination that certain airplanes were missing from the applicability of AD 2014-26-53 and AD 2015-03-02 and that those airplanes may be affected by the unsafe condition addressed in AD 2014-26-53 and AD 2015-03-02. We are issuing this AD to detect and correct discrepancies of the fasteners at the external surface of the lower wing skin and inboard and outboard MLG support rib lower flanges, which could result in an airplane not meeting its maximum loads expected in service. This condition could result in structural failure.
This paragraph restates the requirements of paragraph (g) of AD 2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015), with an extended compliance time and new service information.
