We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767-200 and -300 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the aft pressure bulkhead web to pressure chord joint is subject to widespread fatigue damage (WFD). This proposed AD would require repetitive high frequency eddy current (HFEC) inspections of the aft pressure bulkhead web, at fasteners common to the bulkhead web and pressure chord, around the entire circumference of the pressure chord for any crack, and repair of cracks. We are proposing this AD to detect and correct cracks in the aft pressure bulkhead web. Such cracking could result in the loss of structural integrity of the airplane.
