Unsafe condition
This AD was prompted by a report of missing insulation in the engine pylon area. The FAA is issuing this AD to address missing or damaged insulation in the engine pylon area. The unsafe condition, if not addressed, could result in the bleed duct to radiate heat to the surrounding structure and, if not corrected, could lead to the loss of the structural integrity of the engine pylon and possible loss of the engine.
Affected ADs
None.
