EASA AD 2020-0259
Engine — High Pressure Turbine Rotor Module No 51 Seal Disc — Removal from Service
Summary
The document titled Engine — High Pressure Turbine Rotor Module No 51 Seal Disc — Removal from Service is an explanatory statement issued by EASA regarding the absence of an Airworthiness Directive (AD) for the Europrop International GmbH TP400-D6 engine. It clarifies that no civil aircraft currently operate this engine model, so no public AD exists. The document serves as an informational record and recommends that military authorities issue their own ADs for affected military aircraft equipped with TP400-D6 engines.
What Changed
This document introduces an informational advisory record rather than a formal AD, explaining the lack of a public AD due to the absence of TP400-D6 engines in civil service. It directs military airworthiness authorities to issue their own legally binding ADs for affected military aircraft. No new compliance requirements are imposed by EASA for civil operators.
Why It Matters
This matters because it informs aviation professionals that no civil AD is currently available for the TP400-D6 engine, emphasizing that military operators must follow their respective national military ADs. Maintenance, repair, and overhaul (MRO) organizations and compliance teams should be aware that EASA’s role here is advisory and that legally binding requirements come from military authorities. This helps clarify regulatory responsibilities and prevents confusion regarding compliance.
What To Do
Affected military operators and maintenance organizations should contact their national military airworthiness authorities to obtain the applicable AD for the TP400-D6 engine. Civil operators do not need to take action as no civil AD exists. Stakeholders should monitor updates from their military authorities and the CQC for any future recommendations or mandatory directives.
