The Arrius 2B engines, powering the 27 ÖAMTC’s EC 135T helicopters, clock up today 200,000 flight hours. These twin engine-helicopters’ missions, EMS type, have very important operational constraints.

“This is an important milestone for our EC 135T fleet, which 100% of it is equipped with the Arrius 2B engine, as our entire fleet is powered by Turbomeca engines. The reliability of the Arrius engines and our close working relationship with Turbomeca Germany is a key factor for the success of our missions.” said Martin Weger, Director of maintenance and Wolfgang Burger, Technical Director.
To date, the ÖAMTC’s entire fleet is deployed over 16 bases in the summer and 22 in the winter. Since the beginning, more than 200,000 missions have been accomplished. These missions, EMS type, have very important operational constraints, as the helicopters availability or the high mountain environment. The whole engines fleet is maintained by Heliair, a 35-person team.

Arrius 2B2 to power the EC 135T2

The Arrius 2B2 was designed to allow a greater take-off weight in category A. It offers the best performances at high altitudes and temperatures.
In addition, the engine TBO (Time Between Overhaul) has been expanded up to 4,000 hours.
Customers also benefit from a computerized maintenance aid which allows them to process the data downloaded from the EECU (Engine Electronic Control Unit).
The family of Arrius engines relies on a solid experience of more than 2,500 delivered engines, accumulating over four million flight hours. Turbomeca worldwide network already provides the after sales support of Arrius for 430 customers in 60 countries.
