EASA AD 2018-0253: Superseded by EASA ADR 2019-0161

What to do

Operators and maintenance organizations with military aircraft equipped with TP400-D6 engines should contact their responsible military airworthiness authority to obtain the applicable AD. Design approval holders should be aware that EASA provides this information only to concerned parties and that military authorities are responsible for issuing legally binding directives. No public compliance deadline is specified in this document.

Summary

The document titled SUPERSEDED BY EASA ADR 2019-0161 is an explanatory statement regarding the absence of an Airworthiness Directive (AD) document for Europrop International GmbH TP400-D6 engines. It clarifies that no civil service aircraft currently use these engines, so no public AD exists. The document serves as an informational record for military authorities and design approval holders, recommending that military authorities issue their own ADs for affected aircraft.

What changed

This document introduces an informational Airworthiness Directive record without legally binding requirements due to the absence of TP400-D6 engines in civil service. It clarifies that the applicable ADs for affected military aircraft are issued by the respective military authorities, not EASA. The document itself is superseded by EASA ADR 2019-0161.

Why it matters

This matters for aviation professionals because it clarifies the regulatory status of TP400-D6 engines and directs military operators and maintenance organizations to consult their national military authorities for applicable ADs. It helps ensure that military aircraft with these engines remain compliant with airworthiness requirements through appropriate channels. Compliance teams can avoid confusion about the absence of a public EASA AD for these engines.
