Authorities are investigating what caused a small airplane to crash in Grenville-sur-la Rouge on Thursday evening.

According to Sergeant Louis-Philippe Bibeau of the Sûréte du Québec, an ultralight aircraft had mechanical trouble soon after takeoff from a nearby airfield.  The pilot, a man in his 60s, attempted an emergency landing but crashed in a swamp near a campground on Route 148.

The aircraft caught fire, a witness rescued the pilot who was taken to hospital in Lachute and treated for non life-threatening injuries.  The Grenville-sur-la-Rouge fire department arrived and doused the flames on the burning aircraft.

The federal Transportation Safety Board is investigating the crash.  However, spokesperson Alex Fournier said it is unlikely that investigators will visit the crash site, but they will be contacting the pilot to gather information.
