The Turbomeca (Safran group) Arriel 1D1 “Plus” engine: a technical upgrade package, with an increased T.B.O. of 3,600 hours

Houston, 21 February 2010

The time between overhaul (T.B.O.) of the Turbomeca Arriel 1D1 engine will be increased from 3,000 to 3,600 hours.

This extension of the T.B.O. is possible, first, thanks to customers' feedback and enhanced customer communication which included the exchange of valuable experience from the field. Secondly, this extension is also due to engineering efforts engaged by Turbomeca to design an optimized product, with notably a new second stage turbine assembly, which eliminates the 1,200 hrs inspection.

This extension demonstrates the Arriel 1D1 improved technology and reliability. Featured with a very simple design, a reduced number of parts and only five modules for easy maintenance, the Arriel 1 has gained a solid reputation in the helicopter market based on its excellent handling characteristics and high level of reliability.

"This extension is part of our strategy to maintain our investment for continuous improvement of our product line, reducing the maintenance cost and improving the reliability of our engines,"said Bruno Even, VP & General Manager, Operators.

The Arriel 1D1 powers the single-engine Eurocopter AS 350 B2 Ecureuil and AS 550 Fennec. Certified in 1988 and logging today 5,000,000 hours of flight, the Arriel 1D1 is operated by 466 customers in 57 countries.
The family of Arriel engines relies on a solid experience of 9,000 delivered engines, accumulating 30 million flight hours. Turbomeca worldwide network already provides the after sales support of Arriel for 1,300 customers in 110 countries.
