Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 95-21-09, for all Airbus Model A300 series airplanes, and Airbus Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 95-21-09 currently requires repetitive inspections for cracking of the No. 2 flap beams, and replacement of the flap beams, if necessary; and provides optional modifications for extending certain inspection thresholds, and an optional terminating modification for certain inspections. Since we issued AD 95-21-09, we have determined that the compliance times must be reduced. This proposed AD would reduce the compliance times for inspections and also reduce the number of airplanes affected. We are proposing this AD to detect and correct cracking of the No. 2 flap beams, which could result in rupture of the flap beams and reduced structural integrity of the airplane.
