Kopter has restarted the flight test program for its new SH09 helicopter. Having struggled with technical issues and multi-year delays since its first flight in 2014, the Leonardo group company resumed flying in January. Its sole flying SH09 turbine single P3 prototype has been refitted with a new main rotor head design, a new main gearbox with an extended mast, new flight controls configuration, and Garmin G3000H avionics. Kopter plans to add minor aerodynamic improvements to the cowling before test aircraft PS (pre-series) 4 joins the program in the third quarter of this year, followed by the PS5 prototype “some months later.”
However, the program has a long way to go before certification and the Swiss-based company, acquired by Leonardo last year, still has a variety of commercial and distribution issues to work through as well as the industrialization of components. The retrofitted P3 aircraft flew 25 hours between mid-January and early March, with the test pilots reporting handling much improved.
