Circumstances:
he float-equipped aircraft had landed at Minstrel Island and was taxiing to the dock when the pilot of a company aircraft that was following C-GNWS to the dock radioed that he saw smoke coming from the lower right area of C-GNWS's engine cowling. The pilot of C-GNWS docked the aircraft, unloaded the three passengers and emptied a fire extinguisher onto the burning aircraft. The fire was not extinguished and the aircraft was pushed away from the dock where it burnt to the water.

Circumstances:
A de Havilland DHC-2 Beaver seaplane, registration C-FNFO, serial number 819, departed from Kakabikitchiwan Lake, Ontario, on a visual flight rules flight for Aremis Lake with only the pilot on board. Shortly after take-off, the aircraft was observed flying northbound at a very low altitude above Sabaskong Bay with the engine operating at a high power setting. The aircraft started to climb and bank to the left. The right wing struck the lower of two electrical wires strung across a channel between two islands. The aircraft was destroyed; the pilot sustained fatal injuries.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The power line running overhead the channel was invisible, except at very short range, and was not marked to indicate its presence.
2. The pilot was flying at a very low altitude and likely did not see the power line.
Findings as to Risk:
1. The Standards Obstruction Markings Manual allows for discretion in deciding whether to assess obstructions, making it possible for some obstructions to not be assessed and, consequently, to not be marked.

Circumstances:
The de Havilland DHC-2T Beaver floatplane, serial number 1673TB43, was engaged in aerial application of fish fry to several lakes near Clearwater, British Columbia. The pilot and one other person were on board. The aircraft took off from Clearwater at about 1230 Pacific daylight time (PDT) to begin a planned series of drops to nearby lakes. The aircraft had dropped fish in four lakes before proceeding to Broken Hook Lake.When the aircraft was on approach to the northwestern end of Broken Hook Lake, the pilot reportedly advanced the power lever, but the engine did not respond. At this time, the aircraft was about 100 feet above ground level and struck several treetops. Within seconds, the aircraft descended, struck the terrain, and crashed into trees. The two occupants were seriously injured, and the aircraft was destroyed. There was no fire. The accident occurred at 1320 PDT.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The pilot did not avoid the trees that obstructed his immediate flight path on descent to the lake.
2. The damage to the aircraft from the tree-strike seriously compromised the pilot's ability to control the aircraft, to the point where continued flight was impossible.
3. The pilot and the passenger suffered serious injuries. It is highly likely that proper use of a passenger restraint system would have lessened the injuries to both persons.
Findings as to Risk:
1. Canadian regulations regarding the use of seats and seat restraint systems are not sufficiently clear about high-risk, aerial work operations, such as aerial application.
2. Transport Canada was not advised of the fish-dropping operations and was unaware that the passenger in the cabin was unrestrained during high-risk operations.
3. Canadian regulations do not require specific training in aerial application techniques, such as fish-dropping.
4. The installation of the fish-hopper equipment constituted an aircraft modification, which had not been approved by Transport Canada.
Other Findings:
1. The operator did not maintain a proper logbook.

Circumstances:
The de Havilland DHC-2 (Beaver) floatplane, serial number 841, departed Hotnarko Lake, British Columbia, at about 1630 Pacific daylight time. The pilot and six passengers were on board, with fishing gear and fish. Soon after take-off, the pilot entered a left turn. Before the turn was completed, the aircraft rolled, without command, further left to about 40 degrees of bank and the nose dropped. The aircraft did not respond to initial pilot inputs and continued in a left, diving turn toward the trees at the edge of the lake. The pilot tried to get the aircraft back onto the lake. The aircraft started to recover from the bank and the nose started to come up; however, the aircraft struck the lake surface before a level attitude could be regained. It broke apart on contact with the water and sank soon after. The pilot and four of the passengers managed to free themselves from the wreckage, but only three passengers and the pilot managed to swim to shore. One passenger slipped below the water surface before reaching the shore and drowned. Two passengers remained in the aircraft below the water surface, one secured by his seat belt, and drowned.
Probable cause:
Findings as to Causes and Contributing Factors:
1. When the pilot entered a turn, the combined effects of the increased g-forces, power reduction, the aircraft=s heavy weight, the aft CofG, retraction of the flaps, and the wind conditions resulted in
the aircraft stalling. The aircraft struck the lake surface before the pilot was able to re-establish a level-flight attitude.
2. The aircraft was operating in excess of 385 pounds above the maximum gross takeoff weight, and the CofG was about 2.7 inches aft of the aft limit. This loading configuration aggravated the stall characteristics of the aircraft.
3. The pilot reduced power and raised the flaps before the climb was complete, contrary to the Pilot Operating Handbook, thereby increasing the aircraft's stall speed.
Other Findings:
1. The shoulder harnesses worn by the pilot and the front passenger likely prevented serious head injuries.
2. The centre seat broke from its footings. This may have incapacitated the two passengers inside the aircraft or impeded their escape.

Circumstances:
The DHC-2 Mk. 1 skiplane, registration C-FIVA, serial number 515, with the pilot and five passengers on board, took off from the frozen surface of Lake Adonis, Quebec, on a pleasure flight under visual flight rules (VFR). The route had not been determined, but the flight was to last about 20 minutes. When the aircraft did not return, the search and rescue (SAR) service was advised. The aircraft was found crashed on a mountainside in a wooded area a little less than five km from its point of departure. The pilot and two passengers suffered fatal injuries. The other three passengers suffered serious injuries and hypothermia. The aircraft was destroyed by the force of the impact but did not catch fire. The five passenger, all from the same family, were originating from Marseille, France.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The aircraft probably stalled with insufficient altitude for the pilot to execute a recovery.
2. The prevailing conditions were conducive to optical illusions associated with low-altitude flight over rising terrain.
3. The aircraft was not equipped with a stall warning system, nor was it required by regulation.
4. The pilot's decision to fly at low altitude and probably use cutback power for the climb did not allow for safe obstacle clearance.
5. The pre-flight safety briefing did not inform passengers where to find the survival equipment on board the aircraft. Consequently, they could not use the sleeping bags to protect themselves from exposure and thereby delay hypothermia.
6. Rescue was late because the mostly white aircraft blended into the snowy ground, making it difficult to locate, and the ELT antenna was broken, reducing the range of the signal. Consequently, the survivors' exposure time was increased.
Other Findings:
1. The pilot was certified and qualified for the flight.
2. The autopsy and toxicological test results revealed no indication that physiological factors affected the pilot's performance.
3. Records indicate that the aircraft was certified, equipped, and maintained in accordance with existing regulations and approved procedures.
4. The aircraft's weight and centre of gravity were within the limits specified in the aircraft fight manual.
5. There is no indication that there was an emergency situation or that the aircraft experienced problems prior to impact.
6. The ready-to-use weight and balance calculation form is not consistent with the standard. Transport Canada reported this irregularity in 1992, but no change was made in the form, which is still part of the company operations manual approved by Transport Canada on 23 October 1999.
7. The weather conditions were suitable for visual flight.
1. The aircraft probably stalled with insufficient altitude for the pilot to execute a recovery.

Circumstances:
Witnesses reported that following takeoff from a river, the aircraft climbed to approximately 100 to 400 feet above the water, then initiated a left turn of approximately 45 degrees bank. The majority of the witnesses reported that after the aircraft had turned about 180 degrees, its nose abruptly dropped and it impacted the water. Witnesses did not report observing any evidence of problems with the aircraft before impact, and did not report hearing any abnormal engine sounds or sudden changes in engine pitch. Upon water impact, the aircraft went inverted and its cabin submerged. Efforts by witnesses to gain entry to the aircraft cabin to render assistance were unsuccessful due to aircraft damage. Rescue divers found all occupants deceased in the aircraft upon arrival, but were able to remove the two rear-seat victims without removing any passenger restraints. Autopsies disclosed that all four aircraft occupants had drowned. Investigators did not find any evidence of pre-impact aircraft or engine malfunctions during post-accident examinations of the wreckage, but did find that a cabin entry door was jammed shut due to impact damage, and that the range of travel of both pilot doors was restricted by damaged aircraft components.
Probable cause:
The pilot's failure to ensure attainment of adequate airspeed prior to initiating a steep turn at low altitude, resulting in an accelerated stall. A factor contributing to the occurrence of the accident was the aircraft's low altitude. Factors contributing to the severity of the accident included a water impact, and jammed/restricted doors due to impact damage resulting in degraded aircraft evacuation capability.

Circumstances:
The de Havilland DHC-2 Beaver seaplane departed from Big Trout Lake, Ontario, on a visual flight rules flight for Geraldton, Ontario, with a pilot and an aircraft maintenance engineer on board. After encountering adverse weather conditions en route to Geraldton, the pilot decided to divert to Pickle Lake, Ontario. At about 1430 central daylight time, the engine lost power at an altitude of about 300 feet above ground level while in the descent for Pickle Lake. The pilot turned the aircraft toward a nearby narrow river. In an attempt to restart the engine, the pilot confirmed that the fuel pressure was normal, the fuel selector was on the fullest tank (front), the throttle was at idle, the mixture was rich, and the ignition switch was on both, then he operated the wobble pump. When the engine did not restart, he switched to the centre fuel tank and operated the wobble pump again, but the engine still did not restart. He then switched back to the front tank and tried another restart, without success. He then landed the aircraft on the river at an estimated landing speed of about 40 to 45 mph. After the forced landing, the left wingtip collided with trees on the river bank, and the aircraft yawed to the left about 180 degrees and struck the river bank, breaking off the floats and the float struts. Impact with more trees on the river bank damaged the right wing and elevator. Both occupants were wearing lap belts with shoulder harnesses and were uninjured. The aircraft was substantially damaged. The pilot advised Thunder Bay flight service station by radio of the engine failure and crash and the crew were rescued two hours later.
Probable cause:
Findings as to Causes and Contributing Factors:
- The engine quit operating because the aircraft fuel system was contaminated with a large amount of water.
- The most likely source of the water contamination was the drums from which the aircraft was refuelled.
- A proper filter to prevent water contamination was not used when the aircraft was refuelled.
- The nose-level aircraft attitude when beached and the freezing of water probably prevented the water contamination from being drained from the front tank during the pilot's pre-flight checks.
Other Findings:
- The aircraft's maintenance records indicate that the aircraft was certified, equipped, and maintained in accordance with existing regulations and approved procedures.
- The use of the available shoulder harnesses probably prevented serious injury to the pilot and engineer.
