EASA AD 2025-0226
Engine — Propeller Gear Box / Referenced Flight Cycles — Recalculation / Replacement
Summary
The document titled "Engine — Propeller Gear Box / Referenced Flight Cycles — Recalculation / Replacement" is an explanatory statement related to the absence of an Airworthiness Directive (AD) for the Europrop International GmbH TP400-D6 engine. It clarifies that no Europrop TP400-D6 engines are currently in civil service, and therefore, no public AD exists. The document serves as an informational record provided by EASA to military authorities and design approval holders.
What Changed
This document introduces an informational Airworthiness Directive record without legally binding requirements, as no civil aircraft currently operate the TP400-D6 engine. It recommends that military authorities issue their own ADs for affected aircraft equipped with this engine, depending on their national jurisdiction.
Why It Matters
This matters because it informs aviation professionals that no civil AD is available for the TP400-D6 engine, emphasizing the responsibility of military authorities to manage airworthiness directives for their fleets. Operators, maintenance organizations, and compliance teams should be aware that applicable requirements come from military authorities rather than EASA for this engine model.
What To Do
Stakeholders should contact the responsible military authority in their country to obtain the applicable military AD for aircraft equipped with the TP400-D6 engine. They should monitor the list of CQC AD recommendations available in the EXPERT AREA for updates and ensure compliance with military-issued directives as required.
