What to do
Operators of aircraft with IAE V2500 engines must perform an initial borescope inspection of the diffuser case M-flange based on the engine's cycles since new, with repetitive inspections every 2,100 cycles thereafter. If cracks are found, the diffuser case must be replaced with an approved part immediately. The AD became effective on April 12, 2019, and comments were invited by May 13, 2019.
Summary
FAA Airworthiness Directive 2019-06-06 is a final rule addressing all International Aero Engines AG V2500 turbofan engine models. It mandates initial and repetitive borescope inspections of the diffuser case M-flange and requires replacement of the diffuser case if cracks are detected. This directive aims to prevent uncontained diffuser case rupture that could damage the engine and aircraft.
What changed
This new airworthiness directive introduces mandatory inspections of the diffuser case M-flange on specified IAE V2500 engine models due to detected cracks during overhaul inspections. It requires operators to perform initial and repetitive borescope inspections and replace the diffuser case if cracks are found. The AD is effective immediately with no prior public comment period due to the urgency of the unsafe condition.
Why it matters
This AD is critical for aviation professionals because it addresses a safety risk that could lead to catastrophic engine failure and potential damage to the aircraft. Operators and maintenance organizations must incorporate these inspections into their maintenance schedules to ensure continued airworthiness. Compliance helps prevent uncontained engine failures, enhancing flight safety and reducing operational risks.
