Summary
We propose to supersede Airworthiness Directive (AD) 2000-03- 20 R1, which applies to all Airbus SAS Model A300 B4-601, B4-603, and B4-620, Model A300 B4-600R series, and Model A300 F4-605R airplanes. AD 2000-03-20 R1 requires repetitive ultrasonic inspections to detect cracks on the forward fittings in the radius of a certain frame, adjacent to the tension bolts in the center section of the wings, and various follow-on actions. Since we issued AD 2000-03-20 R1, we have determined that the existing compliance times must be reduced. This proposed AD would retain the requirements of AD 2000-03-20 R1, add new airplanes to the applicability, and introduce new compliance times for the required inspections as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. We are proposing this AD to address the unsafe condition on these products.
