Diamond DA62 — Flight Manual

This document is an Airworthiness Directive (AD) issued by the European Union Aviation Safety Agency (EASA) concerning the E4 series engines used in various Diamond Aircraft models, including the DA 62. The AD addresses potential issues with the timing chain of these engines, which may lead to engine power loss if not properly maintained. It outlines the necessary actions to ensure compliance, including amendments to the Aircraft Flight Manual (AFM) and inspection protocols for the timing chain. The document is crucial for maintaining the airworthiness of affected aircraft and ensuring the safety of operations.

• The AD addresses timing chain issues in E4 series engines installed on Diamond DA 62.
• Operators must amend the AFM to limit windmilling restarts to emergency use only.
• Compliance with the AD is required within 30 days of the original issue date.
• The AD applies to all E4 series engines with configurations '-B' or '-C'.
• Failure to comply with the AD may result in engine power loss and reduced aircraft control.
