Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4-603, B4-605R, B4-620, B4-622, B4-622R airplanes; all Airbus Model A300 C4-605R Variant F airplanes; and certain Airbus Model A300 F4-605R airplanes. This proposed AD was prompted by the manufacturer's review of all repairs accomplished using the structural repair manual. This review was done using revised fatigue and damage tolerance calculations. This proposed AD would require an inspection of the surrounding panels of the left and right forward passenger doors, and corrective actions if necessary. We are proposing this AD to detect and correct previous incomplete or inadequate repairs to the surrounding panels of the left and right forward passenger doors and the fail-safe ring, which could negatively affect the structural integrity of the airplane.
