Pilatus Aircraft has said it expects to have the PC-24 versatile jet certified by the end of this year.
The PC-24 was first announced in 2013 and the first prototype made its maiden flight two years later.
"Our goal is to obtain aircraft certification towards the end of 2017," Pilatus' Chairman Oscar Schwenk said in the company's annual report. "Initial customer deliveries are scheduled immediately afterwards.
"It will be an extremely challenging time. I cannot deny, I am very excited about obtaining certification of the Pilatus PC-24 and seeing it enter the market.
"But excitement will do nothing to advance us. We shall keep our feet firmly on the ground, stable and unwavering, whatever happens."
The PC-24 is powered by two Williams FJ44-4A turbines producing 15000 kN of thrust each, giving the PC-24 a predicted top speed of 425 knots and a range with four passengers of 1950 nm.
Australia's Royal Flying Doctor Service is believed to have at least four of the type on order.
