Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series Airplanes; A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-605R Variant F Airplanes (Collectively Called A300-600)

The FAA proposes to supersede an existing airworthiness directive (AD) for certain Airbus Model A300 B2 and A300 B4 series airplanes; A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R Variant F airplanes (collectively called A300-600). That AD currently requires repetitive inspections to detect cracks in Gear Rib 5 of the main landing gear (MLG) attachment fittings at the lower flange, and repair, if necessary. That AD also requires modification of Gear Rib 5 of the MLG attachment fittings, which constitutes terminating action for the repetitive inspections. This proposed AD would reduce the compliance times for all inspections, and require that you do the inspections in accordance with new revisions of the service bulletins. This proposed AD is prompted by new service information that was issued by the manufacturer and mandated by the French airworthiness authority. We are proposing this AD to prevent fatigue cracking of the MLG attachment fittings, which could result in reduced structural integrity of the airplane.
