Airworthiness Directive · Amendment 39-13449 · Boeing Model 777-200 Series Airplanes
Boeing Model 777-200 Series Airplanes
Model 777-200 series airplanes, variable numbers WA207 and WB325; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Model 777-200 series airplanes. This action requires a surface high frequency eddy current inspection of the web of the aft pressure bulkhead, repetitive inspections, and corrective action, if necessary. This action is necessary to detect and correct cracks or damage to the web of the aft pressure bulkhead, which could enlarge if undetected, leading to rapid decompression of the airplane and consequent possible loss of flight critical systems. This action is intended to address the identified unsafe condition.
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.
