EASA AD 2007-0117-CN
CANCELLED: Engines Formerly Used by Non-Civil Operators — Civil Use
Summary
EASA Airworthiness Directive Cancellation Notice 2007-0117-CN cancels the previous EASA AD 2007-0117 concerning ARRIEL 2 series engines formerly used by non-civil operators such as military entities. These engines are installed on helicopters including Airbus Helicopters AS 350 B3, AS 365 N3, EC 130 B4, EC 155 B1, and Sikorsky S-76C models. The cancellation reflects a change in regulatory approach regarding the airworthiness of these engines for civil use.
What Changed
This cancellation notice officially withdraws EASA AD 2007-0117, which had set conditions for returning ARRIEL 2 engines previously used in non-civil operations to civil service. Instead of an AD, the relevant instructions are now incorporated by reference in the applicable Type Certificate Data Sheet via a Service Bulletin. This change removes the need for an AD to address the airworthiness of these engines when installed on civil aircraft.
Why It Matters
For aviation professionals, this cancellation simplifies compliance by eliminating the AD requirements for ARRIEL 2 engines with prior non-civil use. Operators and maintenance organizations must now follow the instructions referenced in the Type Certificate Data Sheet and associated Service Bulletins rather than an AD. This reduces regulatory burden while maintaining safety through established certification documentation.
What To Do
Affected operators and maintenance providers should refer to the Safran Helicopter Engines or Turboméca Service Bulletin specified in the relevant TCDS EASA.E.001 for instructions on restoring engine conformity. No further action or compliance deadlines are mandated by this cancellation notice. For technical questions, stakeholders should contact Safran Helicopter Engines customer support or EASA Safety Information Section.
