What to do
Operators must remove and replace the affected HPT 1st-stage and 2nd-stage hubs at the next engine shop visit after October 29, 2025, or within 100 flight cycles from that date, whichever is later, before exceeding specified removal cycle limits. Maintenance teams must also ensure that no affected hubs are installed in any engine after the effective date. Compliance with these actions is mandatory to maintain airworthiness.
Summary
The Federal Aviation Administration's Airworthiness Directive 2025-19-13 addresses certain International Aero Engines AG Model V2522-A5, V2524-A5, V2525-D5, V2527-A5, V2527E-A5, V2527M-A5, V2528-D5, V2530-A5, V2531-E5, and V2533-A5 engines. This directive mandates the removal and replacement of specific high-pressure turbine (HPT) 1st-stage and 2nd-stage hubs due to a quality escape identified during angled ultrasonic inspections. The AD aims to prevent potential uncontained failures that could lead to engine and aircraft damage.
What changed
This new airworthiness directive introduces mandatory removal and replacement of affected HPT 1st-stage and 2nd-stage hubs identified by specific part and serial numbers. It also establishes an installation prohibition for these affected hubs in any engine after the effective date. The AD does not amend or supersede any previous directives but adds new compliance requirements.
Why it matters
This AD is critical for aviation professionals as it addresses a safety risk involving potential uncontained failures of turbine hubs, which could cause significant damage to engines and aircraft. Operators and maintenance organizations must ensure compliance to avoid safety hazards and regulatory penalties. The directive also impacts maintenance planning by requiring verification of part eligibility during engine shop visits.
