13 June, 2018: RUAG Aviation has completed the overhaul of a Pratt & Whitney Canada PW206 engine for the first time. The maintenance of the engine that is used in the Airbus H135 and H135M helicopters was carried out in the engine maintenance shop in Stans. The fact that the PW206 engines can now be maintained in-house at RUAG Aviation will boost the availability of the Swiss Air Force’s helicopter fleet.
The Swiss Air Force has more than 20 of these helicopters, which are still listed under their former name “EC635”. Each of these helicopters is provided with two Pratt & Whitney PW206 turboshafts. In the future, all of the engines of the Swiss Air Force’s EC635 are to be maintained by RUAG Aviation in Stans.
