What to do
Operators must remove and replace affected fuel pumps before they exceed the life limits specified in the referenced Rolls-Royce service bulletin. From 12 June 2020, installation of affected parts is permitted only if they are serviceable and replaced within the required life limits. Compliance with these requirements is mandatory to continue operating affected engines safely.
Summary
EASA Airworthiness Directive 2020-0124 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning Rolls-Royce Trent 1000-D2, Trent 1000-J2, and Trent 1000-K2 engines, commonly installed on Boeing 787 aircraft. The directive addresses fuel pump life limitations due to wear-related performance degradation. It mandates replacement of affected fuel pumps to maintain engine performance and safety.
What changed
This directive introduces life limits for fuel pumps with Part Number G5030FPU01 installed on certain Trent 1000 engine models. It requires removal and replacement of affected fuel pumps before exceeding specified life limits as detailed in Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 73-AK581. It also allows installation of serviceable affected parts with the condition that they are replaced within the prescribed life limits.
Why it matters
This directive is critical for aviation professionals to prevent reduced engine thrust caused by fuel pump wear, which could compromise aircraft control. Operators and maintenance organizations must ensure compliance to avoid unsafe conditions and maintain regulatory airworthiness. The directive also provides clear guidance on part serviceability and life limits, aiding compliance and maintenance planning.
