The 19-seat twin engine planes were manufactured by Viking Air Limited at the company’s base in Vancouver, Canada. They will now begin the certification process, before entering service later this summer.
Speaking at Glasgow Airport, Mr Mackay said:
“I’m delighted to officially unveil these new planes, which are moving ever closer to entering service on our PSO routes to Campbeltown, Tiree and Barra.
“The aircraft will come as a welcome sight to the remote communities that rely on these services to keep them connected.
“The flights transport people and goods, playing a crucial role for service industries, fisheries and agriculture. Direct air links also enable visitors to reach the islands easily, boosting local tourism. The new planes mean our PSO routes will continue to be reliable and attractive to travellers.
“The purchase of our own aircraft will encourage more competition for the next contract to operate the PSO routes. That contract has been enhanced, with more flights and better timings to offer local residents and businesses, as well as tourists, an improved service.
“The next stage in the process is for the planes to go through the certification process so the crews can familiarise themselves with them.
“I look forward to seeing the planes take off in full service later this summer.”
