PRODUCTION BASIS ARRIEL 1B, 1E2, 1S, 1S1: Production Certificate Number 5SW. Produced by Safran
Helicopter Engines USA Incorporated in the United States under license agreement from
Safran Helicopter Engines S.A., France.
ARRIEL 1B, 1E2, 1S and 1S1: Engine modules, and parts thereof, produced by Safran
Helicopter Engines S.A., France, conforming to this type certificate are fully
interchangeable with ARRIEL 1B, 1E2, 1S and 1S1 engine modules, and parts thereof,
produced under Production Certificate Number 5SW.
Engines manufactured under Production Certificate Number 5SW shall have the suffix
"TEC" added to the engine serial number and shall be included in the required
identification data as specified by FAR Section 45.
IMPORT REQUIREMENTS To be considered eligible for installation on U.S. registered aircraft, each new engine to be
exported to the United States with the DGAC or EASA airworthiness approval shall have
a Joint Aviation Authorities (JAA) or EASA Form 1, Authorized Release Certificate. The
JAA or EASA Form 1 should state that the engine conforms to the type design approved
under the U.S. Type Certificate E19EU, is in a condition for safe operation and has
undergone a final operational check.

NOTE 6. AIR INTAKE REQUIREMENTS
The ARRIEL engines have not been tested to evaluate the affects of foreign object ingestion.
Foreign object ingestion characteristics of airframe air inlet and engine combination are to be
evaluated prior to approval of the engine installation.
The ARRIEL engines do not have anti-icing provisions and have not been tested to evaluate the
effects of icing conditions. Anti-icing characteristics of airframe, air inlet, and engine combination
are to be evaluated prior to approval of the engine installation.
The ARRIEL 1S and 1S1 engines meet the requirements of FAR 33.68(a)(b) when installed with

ENGINE RATINGS
Engine ratings are based on calibrated test rig with performance under the following conditions:
Static, sea level standard conditions (59oF, 29.92' Hg)
No airbleed, no accessory power extraction
6,000 rpm output shaft drive speed
Heating valve of fuel = 18,556 BTU/lb
The ratings given above are minimum final test performance of production and overhaul engines in
accordance with engine acceptance test specification No. 0.292.00.940.0.
Use the exhaust pip specified below with calibrated test bed air intake No. 6.202.81.719.0:
Exhaust pipe No. 0.292.80.721.0 or No. 0.292.80.738.0
