AD NUMBER: 2005-12-07
MANUFACTURER: Airbus SUBJECT: Airworthiness Directive 2005-12-07 SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for certain Airbus Model A319, A320, andA321 series
airplanes. This AD requires a onetime ultrasonic inspection for
certain airplanes, and repetitive detailed inspections for all
airplanes, for cracking in the forward lug of the support rib 5
fitting of both main landing gear (MLG), and repair if necessary.
This AD also provides for optional terminating actions. This AD is
prompted by a report of a crack found in the forward lugof the
right-hand MLG rib 5 fitting during greasing of both MLG pintle
bearings. We are issuing this AD to find and fix cracking in the
forward lug of the MLG, which could result in failure of the lug
and consequent collapse of the MLG during landing.
