Circumstances:
The pilot and five passengers boarded the float-equipped Beaver aircraft in Atlin, BC, and departed on a visual flight rules (VFR) flight to Dease Lake at 1618 Pacific daylight time (PDT). The flight arrived over Dease Lake at 1735 and proceeded northward over the lake's east shore. Approximately one and one-half miles from the south end of the lake, the aircraft turned to the south to descend for a landing in the middle of the lake. The aircraft was in a fairly steep constant descent when it struck the water. It then nosed over and came to rest with only the bottom of the fuselage visible. The fuselage floated for about 10 minutes, then sank in 120 feet of water. The landing area was approximately one mile from the south end of the lake. The pilot escaped with serious injuries. The five passengers did not exit the aircraft and drowned.
Probable cause:
The cause of the accident is that the pilot did not recognize the glassy-water conditions and did not use the glassy-water landing technique. The following findings were reported:
- Glassy-water conditions prevailed at the time of the landing.
- The aircraft struck the water at a high rate of descent, in a nose-down attitude.
- The passenger pre-flight briefing/card did not adequately prepare passengers to deal with emergency water evacuation.
- The pilot was certified and qualified for the flight in accordance with existing regulations.
- The aircraft was certified, equipped, and maintained in accordance with existing regulations and approved procedures.
- There was no evidence found of any airframe failure or system malfunction prior to or during the flight.
- The weight and centre of gravity were within the prescribed limits.

Circumstances:
On approximately 25-May-1986, the aircraft landed on lake ice at Reliance, NWT; while taxiing the nose gear settled into a crack in the ice. The people of the community managed to prevent the aircraft from sinking further using pallets and empty drums. While the insurance company assessed methods of possibly removing the aircraft it continued to sink, eventually to a depth where only the tail remained above water. A military Chinook helicopter was eventually dispatched to Reliance, and it successfully lifted the aircraft out of the lake, and set it down in front of the weather station pending preparations to sling load it 143 nm to Yellowknife. After lift off, and a distance of approximately 200 yards the helicopter's load master elected to drop the aircraft, which plowed nose first into the lake, through the remaining lake ice. Some parts were salvageable and barged back to Yellowknife, however the aircraft was a total loss.

Circumstances:
A wheel/ski-equipped DHC-3 Otter aircraft was on the return leg of a charter flight to Snegamook Lake to retrieve a hunting party of four, along with their hunting gear and bounty of several hundred ptarmigan. It departed Snegamook Lake at 09:15. After takeoff, the engine began to run rough but improved somewhat when the power was reduced for cruising. As the aircraft was approaching Nipishish Lake, the pilot reported to company dispatch that the engine was again running rough, but he was able to maintain altitude, and he would follow the Crooked River toward Goose Bay in case a precautionary landing became necessary. Three minutes later, C-FAGM called dispatch again, advising them that he was intending to land on a large area on the Crooked River. He also indicated that there was an odour of smoke in the aircraft. The aircraft was in a nose-down, left- bank attitude, with the flaps fully extended and the skis retracted when it struck the frozen surface of the river. The Otter bounced clear of the surface, turned left came to rest in an upright position.
Probable cause:
It was determined that a fatigue-initiated crack in the number nine cylinder head caused the engine to run rough and lose power. While the pilot was manoeuvring for the precautionary landing in whiteout conditions, the aircraft crashed. At impact, the fuel cells ruptured, and a fire erupted which destroyed the aircraft.
