The FAA proposes to supersede Airworthiness Directive (AD) 2019-06-06, which applies to all International Aero Engines AG (IAE) V2500-A1, V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2533-A5 model turbofan engines. AD 2019-06-06 requires initial and repetitive borescope inspections (BSIs) of the diffuser case M-flange and, if it fails the inspection, replacement of the diffuser case with a part eligible for installation. Since the FAA issued AD 2019-06-06, the manufacturer performed an updated safety risk analysis, which reduced the diffuser case M-flange inspection intervals and added the performance of a replacement of the diffuser case M- flange. This proposed AD would require an initial BSI of the diffuser case M-flange and, if it fails the inspection, repetitive BSIs of the diffuser case M-flange until replacement of the diffuser case M-flange is performed. The FAA is proposing this AD to address the unsafe condition on these products.
