AD NUMBER: 2012-01-05
PRODUCT: Certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes; and Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, and F4-605R airplanes.
SUBJECT: Airworthiness Directive 2012-01-05
ACTION: Final Rule
SUMMARY: The FAA Is superseding an existing airworthiness directive (AD) for certain Airbus Model A300 B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes; and Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, and F4-605R airplanes.
That AD currently requires repetitive inspections for cracking in Gear Rib 5 of the main landing gear (MLG) attachment fittings at the lower flange, and repair if necessary; and provides an optional spot-facing modification around certain fastener holes, which would terminate certain repetitive inspections. This new AD mandates the optional spot-facing modification. This AD was prompted by new cases of cracks discovered during scheduled maintenance checks.
The FAA Is issuing this AD to prevent cracking of the Gear Rib 5 right-hand and left-hand attachment fitting at the lower flanges of the MLG, which could result in failed bolts penetrating through the rear spar and into a fuel tank, consequent fuel loss, and reduced structural integrity of the airplane.
DATES: This AD becomes effective June 12, 2012.
