The Scottish Government have refused to say why their pledge to order new Twin Otter aircraft for use on the Barra-Glasgow route has been pushed back to an unspecified date.
In May 2012, Transport Minister Keith Brown said new aircraft would be ordered by October of that year and would be in place by April 1st 2013.
Now, a spokesman said: “We are committed to buying aircraft for use on the Glasgow to Barra, Campbeltown and Tiree PSO routes. This work is progressing now, but a decision on the type of aircraft cannot be taken until we consider the outcome of the tendering process.
“The operating environment at Barra limits the number of aircraft types we can consider, but the specification will be for a twin prop aircraft.”
The spokesman refused to say why the original timeframe had been changed. Twin Otters are made by Canadian firm Viking Air.
The Barra-Glasgow route is due to be re-tendered at the end of March 2016.
