What to do
Operators and maintenance providers should refer to the Safran Helicopter Engines or Turboméca Service Bulletin specified in the Type Certificate Data Sheet EASA.E.073 for instructions on restoring ARRIEL 1 engines to civil conformity. No further action or compliance with AD 2007-0045 is required as it has been cancelled. For technical questions, stakeholders should contact Safran Helicopter Engines customer support or EASA Safety Information Section.
Summary
EASA Airworthiness Directive Cancellation Notice 2007-0045-CN cancels the previous directive EASA AD 2007-0045 concerning ARRIEL 1 series engines formerly used by non-civil operators such as military users. These engines are installed on helicopters including Airbus Helicopters AS 350, AS 365, SA 365, MBB BK-117, Leonardo A109, and Sikorsky S-76. The cancellation reflects a change in regulatory approach regarding the airworthiness of these engines for civil use.
What changed
EASA Airworthiness Directive 2007-0045, which set conditions for returning ARRIEL 1 engines from non-civil to civil use, has been cancelled. Instead of an AD, the relevant instructions for restoring engine conformity are now referenced in a Service Bulletin noted in the applicable Type Certificate Data Sheet. This removes the need for an AD to address the safety risk posed by engines previously operated outside civil aviation oversight.
Why it matters
This cancellation simplifies compliance for operators and maintenance organizations by removing the mandatory AD requirements for ARRIEL 1 engines formerly used by non-civil operators. It clarifies that installation of such engines in civil aircraft is not permitted unless conformity is restored according to the Service Bulletin referenced in the TCDS. This change reduces regulatory burden while maintaining safety through established maintenance and modification instructions.
