EASA AD 2024-0069-E
Engine — High Pressure Compressor / Stage 1 and 2 Rotor Path Liners — Inspection
Summary
EASA Airworthiness Directive 2024-0069-E is an emergency directive addressing inspection requirements for the high pressure compressor stage 1 and 2 rotor path liners on Rolls-Royce Deutschland RB211-524H-36 and RB211-524H-T-36 engines, commonly installed on Boeing 767 aircraft. The directive mandates borescope inspections to detect potential damage that could lead to engine surges and dual engine shutdown. It applies to all manufacturer serial numbers of the affected engines.
What Changed
This new emergency airworthiness directive introduces mandatory inspections of the high pressure compressor stage 1 and 2 rotor path liners due to reported high surge rates and potential part loss. It requires initial and repetitive borescope inspections within specified flight cycle windows and mandates contacting Rolls-Royce for corrective actions if discrepancies are found. The directive also sets conditions for engine installation and inspection compliance.
Why It Matters
This directive is critical for aviation professionals because undetected damage to the rotor path liners could cause dual engine shutdown, severely compromising aircraft control. Operators and maintenance organizations must comply promptly to ensure continued airworthiness and flight safety. Compliance teams need to track inspection intervals and coordinate with Rolls-Royce for any necessary repairs to avoid operational disruptions.
What To Do
Operators must perform an initial borescope inspection within 18 days for one engine and within 50 days for remaining engines installed on an aircraft, starting from 14 March 2024. Subsequent inspections are required within specified flight cycle intervals, and any detected discrepancies must be reported to Rolls-Royce for corrective instructions before further flight. Engines installed after the effective date must be inspected before the next flight and within defined flight cycle windows thereafter.
