GATINEAU, QC, July 17, 2013 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its investigation report (A11Q0136) into
the engine stoppage and forced landing on water of a Cessna A185E,
operated by Air Tamarac Inc., which occurred on 18 July 2011 near La
The Cessna floatplane was providing sightseeing flights in the area of
La Tuque. During the third flight of the day, the aircraft's engine
stopped due to a fuel starvation of the left fuel tank. After deciding
to conduct an emergency ditching on the Bostonnais River, the pilot
unsuccessfully attempted to restart the engine. The terrain surrounding
the river forced the pilot to take a sharp left turn. The aircraft then
stalled, nose-dived, and struck the water. Of the 5 people on board the
aircraft, 1 passenger died as a result of the accident.
The investigation determined that the fuel quantity had not been
measured before the occurrence flight. Furthermore, as the fuel
quantity indicators on this type of aircraft are known to be
unreliable, it was difficult to predict the precise moment when the
tank would run dry. The investigation also determined that the pilot
did not use the auxiliary electric fuel pump to restart the engine.
The investigation identified important safety issues related to the
operation of floatplanes. In this occurrence, Air Tamarac did not
distribute to passengers the Transport Canada guides related to
passenger safety on board floatplanes, and the passenger safety
briefing was incomplete. In addition, the passengers and the pilot did
not grab a personal flotation device in the aircraft before evacuating.
Since the occurrence, Air Tamarac has implemented new safety measures:
all floatplane occupants are now required to wear a personal flotation
device; passenger safety briefings must be provided before engine
start-up; and pilot training now includes initial mandatory training in
underwater evacuation from a submerged aircraft, as well rescue

advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
