RICHMOND, BC, Nov. 6, 2013 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its investigation report (A11P0106) into
the July 2011 collision with terrain of a Cessna 152 near Harrison
Lake, British Columbia.
On 5 July 2011, a Pacific Flying Club Cessna 152, with a flight
instructor and student pilot on board, departed Boundary Bay, British
Columbia, for a mountain training flight. An hour and a half after
departure, the aircraft collided with terrain about 10 nautical miles
west of Harrison Lake. The aircraft was destroyed by impact forces, and
both occupants of the aircraft died.
The investigation found that the accident was likely caused by an
aerodynamic stall while attempting a turn at an altitude from which the
pilots could not recover before colliding with the mountain. Without
proper training in mountain flying techniques, pilots and passengers
are exposed to increased risk of collision with terrain due to the
complex nature of mountain flying.
Following the occurrence, Pacific Flying Club implemented safety
actions. Among them are:
The creation of a formal, regimented Mountain Flying Training Syllabus, and training for all instructors that includes defined procedures for
canyon turns, minimum altitudes, mandatory routing, and standard
Modifications to the Mountain Flying Program, including a ground school prior to flight, prescribed new routing, and
the use of flight training devices to enhance pilot awareness of
