EASA AD 2024-0153
SUPERSEDED BY EASA ADR 2025-0084
Summary
The document titled SUPERSEDED BY EASA ADR 2025-0084 is an explanatory statement regarding the absence of an Airworthiness Directive (AD) for Europrop International GmbH TP400-D6 engines in civil service. It clarifies that no publicly available AD exists because these engines are not used in civil aviation, and the document serves only as information for design approval holders and military airworthiness authorities. The legally binding AD requirements for affected military aircraft with TP400-D6 engines are issued by the respective military authorities of the aircraft's country of registration.
What Changed
This document introduces an informational Airworthiness Directive record (ADR) in the absence of a public AD for the TP400-D6 engine, which is not present in civil service. It recommends that military authorities issue their own ADs for affected aircraft, rather than providing a legally binding directive itself. The document is intended solely for informational purposes and does not impose direct regulatory requirements.
Why It Matters
This matters to aviation professionals because it clarifies the regulatory status of the TP400-D6 engine, ensuring that civil operators are aware no civil AD applies while guiding military authorities on the need for their own directives. Operators, maintenance organizations, and compliance teams can avoid confusion regarding compliance obligations for this engine model. It also directs stakeholders to contact military authorities for applicable ADs, supporting proper regulatory adherence in military aviation contexts.
What To Do
Affected stakeholders, particularly military airworthiness authorities and design approval holders, should use this document as a reference to issue or obtain the appropriate military ADs for aircraft equipped with TP400-D6 engines. Civil operators do not need to take action as no civil AD exists. For copies of applicable military ADs, stakeholders must contact the responsible military authority. No compliance deadlines are specified.
