What to do
Operators must replace at least one affected fuel pump on affected aircraft within 30 days after 17 November 2021, and remove all affected pumps within 250 flight cycles or 14 months after 5 December 2022. Installation of affected engines or fuel pumps is prohibited from 17 November 2021 onward. Compliance must follow Rolls-Royce NMSB RB.211-73-AK788 instructions for fuel pump replacement.
Summary
EASA Airworthiness Directive 2022-0225 is an airworthiness directive addressing Rolls-Royce Deutschland RB211 Trent 800 series engines installed on Boeing 777 aircraft. It mandates replacement of certain Eaton Corporation fuel pumps identified as affected parts due to corrosion and debris issues that can cause engine thrust loss. The directive ensures continued airworthiness by requiring removal and replacement of these fuel pumps to prevent engine in-flight shutdowns.
What changed
EASA Airworthiness Directive 2022-0225 supersedes the previous AD 2021-0245 and introduces a requirement to remove all affected fuel pumps from service for refurbishment, overhaul, or repair rather than just de-pairing. It retains previous prohibitions on installing affected engines or parts and adds a firm deadline for fuel pump replacement within 250 flight cycles or 14 months after the AD's effective date.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving fuel pump corrosion that can lead to dual engine thrust loss or shutdown. Operators and maintenance organizations must comply to maintain aircraft airworthiness and avoid operational disruptions. Compliance teams need to track affected parts and ensure timely replacement to meet regulatory requirements and prevent unsafe conditions.
