Unsafe condition
This AD was prompted by a report of a crack on the centrifugal compressor case mount pad weld area, caused by a non-conforming welding (lack of welding penetration). The FAA is issuing this AD to prevent failure of the centrifugal compressor case. The unsafe condition, if not addressed, could result in crack propagation, possibly resulting in engine separation and reduced control of the airplane.
Affected ADs
None.
