What to do
Affected operators must perform ultrasonic inspections of the HPT 1st-stage and 2nd-stage hubs by August 28, 2023, and replace any hubs found cracked. Comments on the AD are accepted until October 6, 2023. Operators should obtain and follow Pratt & Whitney Special Instruction No. 149F-23 and coordinate with the FAA for any further guidance.
Summary
FAA Airworthiness Directive 2023-16-07 is a final rule addressing certain International Aero Engines, LLC models including PW1122G-JM, PW1124G1-JM, PW1127GA-JM, PW1400G series, and others. It mandates ultrasonic inspections of the high-pressure turbine 1st-stage and 2nd-stage hubs for cracks and requires replacement if cracks are found. This directive follows an incident involving an HPC 7th-stage rotor separation that caused an aborted takeoff on an Airbus A320neo powered by a PW1127GA-JM engine.
What changed
This AD introduces a new requirement for earlier ultrasonic inspections of specific HPT hubs due to updated manufacturer analysis identifying a broader population of susceptible parts, including PW1400G series engines not previously covered. It supersedes prior ADs by expanding the affected engine models and accelerating inspection timelines. The directive also incorporates updated service information from Pratt & Whitney issued in August 2023.
Why it matters
This AD is critical for aviation professionals because it addresses a potential uncontained engine failure risk that could lead to severe damage and loss of aircraft. Operators and maintenance organizations must ensure timely inspections to detect cracks early and prevent catastrophic failures. Compliance helps maintain airworthiness and safety of aircraft powered by affected IAE engines.
