Airworthiness Directive 2012-08-03
one-timeAirworthiness Directives; Airbus Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-2C, B4-103, and B4-203 airplanes; Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310 series airplanes. This AD was prompted by reports of cracking in the forward lug wing of the aft bearing at rib 5 of the main landing gear (MLG). This AD requires installing new bushes with increased interference fit in the forward lug wing of the aft bearing at rib 5 of the MLG on the right-hand (RH) and left-hand (LH) wing. We are issuing this AD to prevent cracking of the forward lug wing of the aft bearing at rib 5 of the MLG, which could adversely affect the structural integrity of the MLG attachment, and could result in the collapse of the MLG.
Which aircraft AD 2012-08-03 applies to
All serial numbers, except airplanes where the main landing gear (MLG) rib 5 forward lugs of the LH and RH wings have been repaired by installation of oversized interference-fit bushes per Airbus Repair Instruction R57240221 (A300) or R57249121 (A310), or where the LH/RH wings have had Airbus Mandatory/Service Bulletin A300-57-0249, A300-57-6106, or A310-57-2090 embodied in service.
Whether AD 2012-08-03 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.
