What to do

Operators of aircraft with IAE V2525-D5 and V2528-D5 engines must perform eddy current and fluorescent penetrant inspections of the turbine exhaust case at the next engine shop visit or within 4,000 flight cycles after September 19, 2019. If no cracks are found, repeat inspections every 2,000 flight cycles. If cracks are detected, the turbine exhaust case must be replaced with an eligible part before further flight.

Summary

The Federal Aviation Administration's Airworthiness Directive 2019-16-01 addresses all International Aero Engines AG V2525-D5 and V2528-D5 turbofan engines. This directive mandates inspections of turbine exhaust cases due to reports of cracks, aiming to prevent engine failure and potential loss of the airplane. It requires initial and repetitive inspections and replacement of affected parts if cracks are found.

What changed

This new airworthiness directive introduces mandatory eddy current and fluorescent penetrant inspections of the turbine exhaust case's front and rear mount stiffener rails. It establishes compliance timelines, requiring inspections at the next engine shop visit or within 4,000 flight cycles after the effective date, with repetitive inspections every 2,000 flight cycles thereafter. If cracks are confirmed, the affected part must be replaced before further flight.

Why it matters

This directive is critical for aviation professionals as it addresses a safety risk that could lead to engine separation and loss of the aircraft. Operators and maintenance organizations must incorporate these inspections into their maintenance schedules to ensure continued airworthiness. Compliance helps prevent unplanned engine removals and enhances overall flight safety.
