Abstract
We are superseding Airworthiness Directive (AD) 2000-12-12, for certain Airbus Model A300, A300-600, and A310 series airplanes. AD 2000-12-12 required inspecting to detect cracks in the lower spar axis of the nacelle pylon between ribs 9 and 10, and repair if necessary. AD 2000-12-12 also provided for optional modification of the pylon, which terminated the inspections for Model A300 series airplanes. This new AD reduces the initial and repetitive inspection compliance times. This AD was prompted by reports of cracking of the lower pylon spar after accomplishing the existing modification. We are issuing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the lower spar of the nacelle pylon.
