Airworthiness Directives; Airbus Model A300 B2 and B4 Series Airplanes

The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A300 B2, B4-100, and B4-200 series airplanes. That AD currently requires supplemental structural inspections to detect fatigue cracking, and repair of cracked structure. This new AD requires revising the maintenance program by incorporating new and revised supplemental structural inspections, inspection intervals, and repairs; and repair of any damaged, cracked, or corroded structure; which would end the existing supplement structural inspections. This AD results from a review of service history and reports received from the current supplemental structural inspection document program. We are issuing this AD to prevent reduced structural integrity of these airplanes due to fatigue cracking.
