Circumstances:
The BN-2A Islander was on a night visual approach to Norman Wells (YVQ) in conditions of low ceilings and reduced visibility. At 500 feet above ground level (agl), the aircraft was in and out of the cloud base, and the pilot observed lights below. Believing he was over the town of Norman Wells, the pilot descended in an attempt to get below the cloud base for a visual right-hand circling approach to runway 08. The pilot was turning onto a northerly heading, when the aircraft struck the ice of the Mackenzie River. The right main gear broke off, and the aircraft bounced and remained airborne for approximately half a mile. It then skidded 600 feet along smooth ice into an area where large blocks of ice brought the aircraft to a stop.
Probable cause:
The following findings were reported:
- The pilot mistook the lights of the oil installations for the lights of the town,
- In an attempt to maintain visual contact with the ground, the pilot descended below a reported 500-foot cloud base in an area where the cloud merged with ground fog, with the result that the aircraft descended to ground level,
- The unserviceable instrument panel light for the pilot's altimeter prevented the pilot from having continuous altitude information.

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.

Crash of a De Havilland DHC-6 Twin Otter 200 in Fort Franklin: 7 killed

Aircraft flight hours:

Circumstances:
The aircraft departed Fort Norman at 16:51 and arrived overhead Fort Franklin at approximately 17:15. Because Fort Franklin was shrouded in fog, a local resident contacted the pilot on a portable VHF transceiver and advised him that there was little or no visibility. The pilot replied that he did not think he would be able to land. The resident drove to the airstrip and contacted the pilot again when he heard the aircraft returning. He advised the pilot that visibility was 200-300 feet. The pilot then asked if this was the vertical or horizontal visibility. At that moment the Twin Otter struck a 200-foot-high telecommunications tower while in controlled level fight. Part of the right wing broke off and the aircraft slowly rolled over before striking the ground. The decision of the pilot to continue the approach in foggy weather were possibly influenced by the effects of stress and a greater than usual personal need to complete the flight. The stress was probably caused by the fact that the pilot had been involved in four accidents since March 1984. Although he was a very experienced pilot, his previous employer terminated his employment on 31 August 1984. In their opinion, his ability to make operational decisions was in question. The pilot was hired by Nahanni Air Services one month later.
Probable cause:
The following findings were reported:
- The weather at Fort Franklin was unsuitable for the flight,
- The flight was continued into weather below that which is required for VFR flight,
- An approach to the aerodrome was attempted using the radar altimeter to provide terrain clearance,
- The pilot descended to an altitude below the height of the telecommunications tower,
- A lack of official weather observations and of communications facilities at Fort Franklin deprived the pilot of reliable local weather information on which to base his decisions,
- There exists in the more remote areas of Canada a different attitude with regard to the assessment of risk in flight operations; it is likely that this attitude influenced the decisions and actions of the pilot,
- The operational decisions of the pilot may have been influenced by the effects of stress and a greater than usual personal need to complete the flight,
- Company management may have had a better appreciation of the risk potential associated with the recent events in the pilot's life, if they had more awareness of the effects of stress on performance.

Circumstances:
On approach to Paulatuk Airport, the pilot encountered marginal weather conditions with strong cross winds and blowing snow. On short final, while making a transition from visual to instruments flight rules, the pilot decided to initiate a go-around when the left wing struck the ground. Out of control, the aircraft veered to the left and came to rest. The pilot and a passenger were killed while 10 other occupants were injured.
Probable cause:
It was determined that the accident was the consequence of the combination of the following factors:
- The Paulatuk aerodrome runway is not oriented to correspond with the prevailing winds,
- Environment Canada does not produce an aerodrome forecast for Paulatuk,
- As the aircraft landed, the crosswind from the right increased appreciably reducing visibility in blowing snow,
- During the overshoot, as the pilot was making the transition from visual to instrument flight conditions, control of the aircraft was lost,
- The aircraft was overloaded by 840 lbs.

Circumstances:
On final approach to Nanisivik in marginal weather conditions, the airplane nosed down to an angle of 45° then banked to the right to an angle of 80° and crashed 670 meters short of runway. Due to blizzard, SAR operations were hampered and rescuers arrived on the crash site 24 hours later only. The aircraft was destroyed and all eight occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. The assumption that the loss of control may have been caused by windshear or an in-flight failure of the flap and/or aileron control rod was not ruled out.
