EASA AD 2025-0084
Engine — Propeller Gearbox Module Propeller Shaft — Replacement
Summary
The document titled 'Engine — Propeller Gearbox Module Propeller Shaft — Replacement' is an informational Airworthiness Directive record created by EASA regarding 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 document exists. The document serves as a recommendation for military authorities responsible for aircraft equipped with TP400-D6 engines to issue their own applicable ADs.
What Changed
This document introduces an informational AD record rather than a legally binding directive, due to the absence of TP400-D6 engines in civil aviation. It provides guidance to military airworthiness authorities and design approval holders but does not impose new regulatory requirements. The document directs stakeholders to obtain applicable military ADs from their respective authorities.
Why It Matters
This matters because it informs aviation professionals that no civil AD exists for the TP400-D6 engine, preventing confusion about compliance obligations. Operators and maintenance organizations dealing with military aircraft equipped with this engine must rely on military-issued ADs for airworthiness directives. It ensures clarity on regulatory responsibility and helps maintain safety standards through appropriate military channels.
What To Do
Affected stakeholders, including military operators and maintenance organizations, should contact their responsible military airworthiness authority to obtain the applicable AD for aircraft with TP400-D6 engines. No civil compliance action is required at this time. Stakeholders should monitor updates from their military authorities and consult the CQC AD recommendations list available in the EASA Expert Area.
