2005-04-18: The pilot of C-FDBO
, a Cessna 172, was conducting a survey flight about 15 NM east of Watson Lake, YT when the aircraft encountered a downdraft. The pilot was flying at 100 to 200 feet AGL and was unable to climb out of it. The aircraft settled into trees, causing damage to both wings, the main landing gear and tail. The pilot, who was wearing a helmet and harness, was not injured and was able to walk from the site. TSB reported that the privately registered Cessna 172K, C-FDBO
, was performing low level survey work 15 NM east of Watson Lake, YT. After completing the first survey pass in a valley, the pilot attempted to turn around at about 150 feet AGL for the second pass and encountered downdrafts near the edge of the valley. The pilot attempted to recover by applying full power and turning towards the descending terrain. The aircraft struck several tree tops before coming to rest in a near upright position at the bottom of the valley. The pilot, who was wearing a shoulder harness and flight helmet, was the lone occupant and received no injuries. The ELT transmitted for 10 minutes prior to the pilot shutting it off and walking out to the nearby road. The aircraft sustained substantial damage to the wings and fuselage.
