Airworthiness Directives; The Boeing Company Model 767-200 and -300 Series Airplanes

Samenvatting

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 reports of cracks in the inner chords at both left-side and right-side stations 859.5, 883.5, and 903.5. This proposed AD would require repetitive inspections of the frame inner chord transition radius for cracks, and related investigative and corrective actions if necessary. We are proposing this AD to prevent large cracks in the frames and adjacent structure that can adversely affect the structural integrity of the airplane.
