What to do
Operators must remove and replace affected fuel pumps before they exceed the specified life limits outlined in Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 73-AK581 Revision 2. Compliance must be achieved by the effective date of 21 January 2021, and any installation of affected parts after this date must comply with the new life limits. Engine rating changes after the effective date require assessment to determine applicable life limits and possible immediate replacement if limits are exceeded.
Summary
EASA Airworthiness Directive 2021-0006 is an airworthiness directive addressing fuel pump replacement life limitations for Rolls-Royce Trent 1000 series engines installed on Boeing 787 aircraft. It mandates the removal and replacement of specific fuel pumps with part numbers G5030FPU01 and TPS1000-05 before exceeding newly established reduced life limits to prevent fuel pump performance degradation. This directive applies to all serial numbers of affected Trent 1000 engine models.
What changed
EASA Airworthiness Directive 2021-0006 supersedes the previous AD 2020-0154 and introduces new and reduced life limits for the affected fuel pumps depending on the engine model rating. It expands the applicability to include additional engine models and allows installation of affected parts only if they have not exceeded the updated life limits. The directive retains previous requirements while updating compliance instructions based on the latest Rolls-Royce service bulletin revision.
Why it matters
This directive is critical for aviation professionals because it addresses a safety concern related to fuel pump wear that can reduce engine thrust and potentially affect aircraft control. Operators and maintenance organizations must ensure compliance to avoid in-service failures and maintain regulatory airworthiness. The updated life limits require careful tracking of fuel pump usage and timely replacement to prevent unsafe conditions.
