EASA AD US-2024-11-03
Engine - 1st-Stage Hubs and 2nd-Stage Hubs - Inspection / Replacement
Summary
The Federal Aviation Administration's Airworthiness Directive 2024-11-03 addresses certain International Aero Engines, AG Model V2500 engines installed on aircraft such as the Airbus A320neo and A321-231. This directive requires angled ultrasonic inspections and accelerated replacement of specific high-pressure turbine 1st-stage and 2nd-stage hubs due to a risk of failure caused by a nickel powdered metal anomaly. The AD aims to prevent unsafe conditions resulting from hub failures that could lead to engine shutdowns or uncontained engine debris.
What Changed
This new airworthiness directive introduces mandatory angled ultrasonic inspections of affected high-pressure turbine hubs and requires their replacement if cracks are detected. It also mandates accelerated replacement schedules for certain hubs manufactured from a specific production batch. The AD incorporates clarifications on affected parts, compliance timing, and eligibility for installation based on inspection results.
Why It Matters
This AD is critical for aviation professionals as it addresses a safety risk that could cause engine failures and aborted takeoffs, impacting flight safety and operational reliability. Operators and maintenance organizations must comply to avoid uncontained engine events and ensure continued airworthiness. The directive affects maintenance planning, parts inventory, and inspection procedures, requiring timely action to mitigate risk.
What To Do
Operators and maintenance providers must perform angled ultrasonic inspections on specified high-pressure turbine 1st-stage and 2nd-stage hubs and replace any cracked parts. Accelerated replacement of certain hubs is also required according to the compliance schedule. All actions must be completed by June 26, 2024, the effective date of the AD, with flight cycle limits counted from this date. Service information from International Aero Engines, AG should be consulted for detailed procedures and affected part identification.
