The Transportation Safety Board confirms the plane that crashed last month near the Thompson airport, was filled with the wrong type of fuel.

In a report, the TSB says the twin piston-engine aircraft requires aviation gasoline but was re-fueled with turbine engine fuel in Thompson, before departing for Winnipeg.   

The investigation is still ongoing. Next steps include further examination of aircraft fueling procedures and practices, and additional examination of aircraft wreckage.

The Keystone Air Service flight departed from Thompson on September 15, but shortly after takeoff the crew experienced a malfunction and alerted the Thompson Airport that they were returning.

The aircraft ended up crashing into terrain, 1 mile away from the Thompson airport. All 6 passengers and 2 pilots survived.
