Unsafe Condition
Cracking in the aft mount beam assembly of the engine could result in reduced structural integrity of the aft mount beam assembly.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 500 flight hours after the effective date, perform a visual inspection to detect cracks in the aft mount beam assembly. If cracks are found, replace the cracked beam with a new beam or beam assembly before further flight. Within 4,000 flight cycles after the effective date, perform a fluorescent penetrant inspection followed by eddy current inspection if no cracks are found, and replace any cracked beams before further flight.
