The SKYe SH09 is a single-engine helicopter developed by Marenco Swisshelicopter. The helicopter was launched in 2011, and assembly of the first prototype was completed in June 2013. The prototype was rolled out in November 2013, and first flight was achieved in October 2014.

The first flight of the second prototype took place in February 2016. The EASA and FAA certifications for the helicopter were expected to be obtained by 2017 and 2018, respectively.

The helicopter will provide medical evacuation and other critical tasks.

Marenco Swisshelicopter secured an order for 45 units of SH09 helicopters at the Heli Expo show, held in Las Vegas, US, in February 2013. The helicopters will be produced at the company’s production site in Niederurnen, Switzerland. The final assembly of the helicopter will take place at Mollis Airport.

The helicopter is expected to largely attract operators located in the US and Canada because there is a strong need for single-engine use in these markets. Marenco Swisshelicopter is also planning to introduce the SKYe SH09 helicopter in emerging markets, such as Brazil, China and Oceania. Heliflite was selected as the distributor of the helicopter in the Oceania region.
