Circumstances:
A Cessna 208 Caravan I on amphibious floats, C-GMPB, serial number 20800082, was ferrying members of the Royal Canadian Mounted Police (RCMP) Emergency Response Team from Teslin, Yukon, to a site on the south end of Teslin Lake, British Columbia. At about 1645 Pacific daylight time, three team members, two dogs, and gear were unloaded on a gravel bar across from the mouth of the Jennings River. The aircraft departed for the Teslin airport at about 2355 with the pilot and one RCMP engineer on board. Shortly after take-off, the aircraft was seen to pitch up into a steep climb, stall, then descend at a steep angle into the water. The aircraft was destroyed, and the pilot and the passenger were fatally injured.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The pilot's decision to depart from the unlit location was likely the result of the many psychological and physiological stressors encountered during the day.
2. The pilot most likely experienced spatial disorientation-precipitated by local geographic and environmental conditions-and lost control of the aircraft.
Findings as to Risk:
1. Without a safety management program that routinely disseminates safety information, RCMP pilots may be inadequately sensitized to the limitations of decision making and judgement.
2. The RCMP had no current, concise standard operating procedures (SOPs) for its non-604 operations. Without useable SOPs, the pilots in some instances operate without clearly established limits and outside of acceptable tolerances.

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.
