What to do
Operators and maintenance providers must perform angled ultrasonic inspections of the HPT 1st and 2nd stage hubs and HPC 7th and 8th stage integrally bladed rotors by the effective date. They must replace any parts found cracked or otherwise non-compliant and adhere to the accelerated replacement intervals specified. The AD becomes effective on April 11, 2024, and compliance must be achieved by that date or as specified in the service information.
Summary
Airworthiness Directive 2024-05-11 is a final rule issued by the Federal Aviation Administration addressing certain International Aero Engines, LLC Model PW1100G and PW1400G series engines. It mandates inspections and accelerated replacements of high-pressure turbine 1st and 2nd stage hubs, high-pressure compressor 7th and 8th stage integrally bladed rotors, and the HPC rear hub to mitigate risks associated with powdered metal anomalies. This directive aims to prevent uncontained failures that could lead to engine and aircraft damage.
What changed
This AD supersedes previous ADs 2022-19-15 and 2023-16-07 by retaining angled ultrasonic inspection requirements and adding inspections for HPC 7th and 8th stage integrally bladed rotors. It introduces accelerated replacement schedules for multiple components including the HPC IBR-7, IBR-8, rear hub, and HPT hubs. The compliance times were corrected to require earlier removals than previously proposed.
Why it matters
The directive addresses an increased risk of premature failure in powdered metal parts critical to engine safety, which is vital for operators and maintenance organizations to prevent uncontained engine failures. Compliance ensures continued airworthiness and safety of aircraft powered by affected IAE engines. It also impacts maintenance planning and operational scheduling due to required inspections and accelerated part replacements.
