Action
Final rule.
Summary
We are superseding Airworthiness Directive (AD) 2003-18-10 for certain The Boeing Company Model 767 airplanes. AD 2003-18-10 required revising the Airworthiness Limitations Section of the maintenance planning data (MPD) document. This new AD also requires revising the maintenance program to incorporate an additional limitation, which terminates the existing requirements; and adds airplanes to the applicability. This AD was prompted by a re-evaluation of certain doors and flaps based on their fatigue-critical nature. We are issuing this AD to detect and correct fatigue cracking of the principal structural elements (PSEs), which could adversely affect the structural integrity of the airplane.
