1999-04-15: The pilot and four passengers aboard C-FDMA
, a Cessna 206, were conducting an aerial survey of Doll sheep approximately 40 miles south of Norman Wells. It was reported that the a/c was flying in a canyon and may have encountered a downdraft which caused the Cessna to collide with the upslope of rising terrain. The a/c was reported to have overturned after hitting the ground and went over the top of a ridge, sliding down the other side of the ridge. Althought the Cessna 206 is described as being damaged beyond repair, the five occupants survived the accident and were airlifted by helicopter to hospital in Norman Wells. The ELT apparently did not activate and the wreckage was located by the operator, who initiated a search after the plane became overdue. The extent of the injuries is not known at this time. Weather was described as good VFR. TSB has been informed and more information may be available. OPI - System Safety UPDATE TSB reported that the damage to the a/c is substantial and there were minor injuries to the pilot and one passenger. The pilot attempted to fly over a ridge, misjudged his altitude and struck the ridge. At the time of the accident the weather was high overcast, ambient lighting was flat and the pilot reported that he had difficulty judging his height above the terrain.
