Fatal Mountain Training Flight Involving a Cessna 152 in British Columbia

Accident Overview and Flight History On July 5, 2011, at 1500 Pacific Daylight Time, a Pacific Flying Club Cessna 152, registration C-GZDR, departed Boundary Bay Airport (CZBB) in British Columbia for a mountain training flight. The aircraft was carrying a flight instructor and a student pilot. The planned itinerary involved a northbound route to Whistler via Indian Arm, a touch-and-go landing at Pemberton Airport, and a return toward CZBB via Harrison Lake. The flight was expected to last 158 minutes and consume 17 gallons of fuel, leaving a reserve of approximately 7 gallons. The student pilot completed the pre-flight inspection and sign-out procedures before meeting with the instructor for a briefing. While the specific content of the briefing is unknown, the instructor's past practices consistently included discussions on mountain-flying hazards and procedures. The student's navigational flight log indicated that the aircraft followed the planned routing. At approximately 1630, the aircraft collided with terrain at an elevation of 2,750 feet above sea level, about 10 nautical miles west of Harrison Lake, in daylight conditions. The emergency locator transmitter activated and was detected by the SARSAT system at 1636, alerting the Rescue Coordination Centre in Victoria, British Columbia, which initiated a search. The aircraft was destroyed by impact forces, and both occupants were fatally injured. No fire occurred.
