Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
At the next engine shop visit after the effective date of the AD or before accumulating 10,000 cycles since new, whichever occurs first, remove the affected diffuser case assembly from service and replace with a part eligible for installation. Note to paragraph (g): IAE Non-Modification Service Bulletin (NMSB) V2500-ENG-72-0707, dated July 1, 2019, contains guidance for replacing the diffuser case assembly.
Unsafe condition
This AD was prompted by a report of a manufacturing quality escape that could impact the life of the diffuser case assembly. The FAA is issuing this AD to prevent failure of the diffuser case assembly. The unsafe condition, if not addressed, could result in the uncontained release of the diffuser case assembly, damage to the engine, and damage to the airplane.
Affected ADs
None.
