Safran Engines Get FAA Flameout Prevention Software Update
Published Date: 2/25/2025
Proposed Rule
Summary
If you own a Safran ARRIUS 2B2 helicopter engine, listen up! The FAA wants you to run regular tests to prevent engine flameouts caused by clogged fuel injectors and update your engine’s software. Some engines might need injector replacements too, so get ready to keep your flights safe and smooth without breaking the bank.
Analyzed Economic Effects
3 provisions identified: 0 benefits, 3 costs, 0 mixed.
Mandatory engine flameout testing
If you own or operate a Safran Model ARRIUS 2B2 engine, the FAA proposes you must perform initial and repetitive non‑extinguishing tests for engine flameout to check for clogging of the preference injector caused by fuel coking. This testing requirement applies to all ARRIUS 2B2 engines under the proposed airworthiness directive.
One-time EECU software upgrade
The proposed AD would require a one-time modification: a software upgrade of the electronic engine control unit (EECU) on Safran ARRIUS 2B2 engines. All ARRIUS 2B2 engine owners/operators subject to the AD would need to install this EECU software update.
Preference injector replacement rules
Under the proposed AD, operators must replace the preference injector if testing shows it is clogged, and certain engines will require repetitive replacements of the preference injector as specified in the referenced EASA AD. The replacement requirements apply to ARRIUS 2B2 engines covered by the FAA proposal and may be repetitive for some engines.
