Airworthiness Directive 2012-06-11
one-timeAirworthiness Directives; Airbus Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Airbus Model A321-131, -211, -212, and -231 airplanes. This AD requires a rotating probe inspection for cracking of the lower panel bore holes of the center wing box (CWB), and corrective actions if necessary. This AD was prompted by reports of incorrect installation of rib pads of the lower aft panel of the CWB due to poor clamping during drilling, and reports that metal chips trapped between panels and stiffeners could impact the fatigue life of CWB panels. We are issuing this AD to detect and correct cracking and damage in the bore holes of the rib pads of the lower forward and aft panels of the CWB which could result in reduced structural integrity of the wings.
Which aircraft AD 2012-06-11 applies to
Applies only to airplanes having the specific manufacturer serial numbers listed (discrete list, not a contiguous range).
Whether AD 2012-06-11 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
