Airworthiness Directive · Amendment 39-8915 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 767-200 Series, 767-300 Series, 767-300F Series.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires dye penetrant inspections and proof pressure testing to detect cracks or ruptures of the crossover pneumatic duct, and repair or replacement, as necessary. This amendment also requires stress relieving of the crossover pneumatic duct assembly. This amendment is prompted by reports of ruptured engine bleed air crossover ducts. The actions specified by this AD are intended to prevent failure of the engine bleed air crossover duct, which could result in loss of pneumatics and damage to adjacent structure.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
