Yukon Otter Crash During Diamond Drill Move (C-FBCG)

Pelly Crossing, CanadaTakeoff (climb)

On May 29, 1990, a De Havilland DHC-3 Otter (registration C-FBCG) operated by Aerokon Aviation was involved in an aviation accident near Pelly Crossing, Canada during takeoff. No fatalities were reported. Investigators recorded the probable cause as: The use of partial power for take-off and the retraction of the flaps prior to reaching a safe altitude and airspeed caused the aircraft to lose altitude and contact the trees during the climb out. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

An Otter carrying drill equipment crashed into trees shortly after takeoff from Pelly Crossing Airport in the Yukon. The pilot and passenger escaped with serious injuries.

Incident Overview and Load Details An Otter was operating a diamond drill move from Pelly Crossing Airport in the Yukon to a site 45 miles to the east. The aircraft carried 2,300 pounds of drill equipment, along with the pilot and one passenger. With this load and fuel, the aircraft's weight was just under the maximum authorized weight of 8,000 pounds. ## Departure and Loss of Altitude Pelly Crossing Airport had a 3,000-foot east/west gravel runway at an elevation of 1,870 feet in mountainous terrain. The pilot departed runway 07 using a reduced power setting and, upon becoming airborne, pumped the flaps to the full-up position. The aircraft began to settle toward the trees off the end of the strip. The pilot applied full power, but as the aircraft continued to settle into the trees, the throttle was closed. ## Impact, Fire, and Injuries The Otter descended into the trees, burst into flames, and was destroyed by a post-impact fire. The pilot was able to egress the aircraft and helped the passenger out. Both received serious burns and other injuries.

Probable cause

The use of partial power for take-off and the retraction of the flaps prior to reaching a safe altitude and airspeed caused the aircraft to lose altitude and contact the trees during the climb out.
