EASA AD 2020-0154
SUPERSEDED BY EASA AD 2021-0006
Summary
EASA Airworthiness Directive 2020-0154 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Rolls-Royce Deutschland Trent 1000 engines installed on Boeing 787 aircraft. The directive addresses fuel pump life limitations for specific part numbers to prevent reduced engine thrust due to fuel pump wear. It applies to multiple Trent 1000 engine variants and mandates replacement of affected fuel pumps before exceeding revised life limits.
What Changed
EASA Airworthiness Directive 2020-0154 supersedes the previous AD 2020-0124 and expands the applicability to additional Trent 1000 engine models. It introduces a new affected fuel pump part number (TPS1000-05) and implements new and reduced life limits for these fuel pumps depending on engine rating. The directive retains previous requirements but updates compliance criteria to reflect the latest manufacturer service bulletin.
Why It Matters
This directive is critical for aviation professionals to ensure continued airworthiness and safe operation of Trent 1000 engines by preventing fuel pump failures that could reduce engine thrust. Operators and maintenance organizations must track fuel pump life limits carefully to avoid unsafe conditions. Compliance ensures regulatory adherence and helps maintain engine performance and aircraft control.
What To Do
Operators must remove and replace affected fuel pumps before they exceed the specified life limits as detailed in Rolls-Royce Alert Non-Modification Service Bulletin TRENT 1000 73-AK581 Revision 1. Compliance with these requirements is mandatory from the effective date of 17 July 2020. Installation of affected parts is allowed only if they have not exceeded life limits, and subsequent replacements must follow the AD's instructions.
