Calgary

The pilot and 3 passengers boarded the aircraft. At 2126, the pilot obtained an IFR clearance from the CYLW ground controller for the KELOWNA SEVEN DEP standard instrument departure (SID) procedure for Runway 34. The instructions for the runway 34 KELOWNA SEVEN DEP SID were to climb to 9000 feet ASL, or to an altitude assigned by air traffic control (ATC), and to contact the Vancouver Area Control Centre (ACC) after passing through 4000 feet ASL. The aircraft was then to climb and track 330° magnetic (M) inbound to the Kelowna non-directional beacon (LW). From LW, the aircraft was to climb and track 330°M outbound for vectors to the filed or assigned route. At 2127, C-GTNG began to taxi toward Runway 34. At 2131, the CYLW tower controller cleared the aircraft to take off from the intersection of Runway 34 and Taxiway D. The pilot acknowledged the clearance and began the take-off roll on Runway 34 about 1 minute later. Radar data showed that, at 2133:41, the aircraft was 0.5 nautical miles (nm) beyond the departure end of the runway and was climbing at more than 4000 feet per minute (fpm) through 2800 feet ASL, at a climb angle of approximately 16°. In that time, it had deviated laterally by about 3° to the right of the 330°M track associated with the SID. At 2134:01, when the aircraft was 1.2 nm beyond the runway, it had climbed through 3800 feet ASL and deviated further to the right of the intended routing. The aircraft’s rate of climb decreased to about 1600 fpm, and its ground speed was 150 knots. A short time later, the aircraft’s rate of climb decreased to 600 fpm, its climb angle decreased to 2°, and its ground speed had increased to 160 knots. At 2134:22, the aircraft was 2.1 nm beyond the departure end of the runway, and it was climbing through approximately 4800 feet ASL. The aircraft had deviated about 13° to the right of the intended track, and its rate of climb reached its maximum value of approximately 000 fpm, 3 with a climb angle of about 22°. The ground speed was roughly 145 knots. At 2134:39, the aircraft was 2.7 nm beyond the departure end of the runway, passing through 5800 feet ASL, and had deviated about 20° to the right of the intended routing. The rate of climb was approximately 2000 fpm, with a climb angle of about 7°. According to the SID, the pilot was to make initial contact with the ACC after the aircraft had passed through 4000 feet ASL.Initial contact was made when the aircraft was passing through 6000 feet ASL, at 2134:42. At 2134:46, the ACC acknowledged the communication and indicated that the aircraft had been identified on radar. The aircraft was then cleared for a right turn direct to the MENBO waypoint once it was at a safe altitude, or once it was climbing through 8000 feet ASL. The aircraft was also cleared to follow the flight-planned route and climb to 10 000 feet ASL. At 2134:55, the pilot read back the clearance as the aircraft climbed through 6400 feet ASL, with a rate of climb of approximately 2400 fpm. The aircraft was tracking about 348°M at a ground speed of about 170 knots. At 2135:34, the aircraft began a turn to the right, which was consistent with the instruction from the ACC. Flying directly to the MENBO waypoint required the aircraft to be on a heading of 066°M, requiring a right turn of about 50°. At this point, the aircraft was still climbing and was passing through 8300 feet ASL. The rate of climb was about 3000 fpm. The aircraft continued the right turn and was tracking through 085°M. After reaching a peak altitude of approximately 8600 feet ASL, the aircraft entered a steep descending turn to the right, consistent with the characteristics of a spiral dive. At 2135:47, the ACC controller cleared C-GTNG to climb to FL 250. The lack of radar returns and radio communications from the aircraft prompted the controller to initiate search activities. At 2151, NAV CANADA notified first responders, who located the accident site in forested terrain at about midnight. The aircraft had been destroyed, and all of the occupants had been fatally injured.

The crew was preparing the aircraft to perform a cargo flight to Calgary (flight NRL920). While taxiing, the aircraft went out of control, collided with a parked Ameriflight Piper PA-31 before coming to rest against a metallic fence. Both pilots were uninjured while the aircraft was damaged beyond repair.

The Alta Flights Cessna 414A (registration C-GVZE, serial number 414A0219) departed Cranbrook, British Columbia, at approximately 1910 mountain daylight time (MDT) on a visual flight rules cargo flight to Calgary, Alberta. The aircraft disappeared from the Calgary area radar at 1936 MDT, at an indicated altitude of 9000 feet above sea level (asl) in the Highwood Range mountains, approximately 49 nautical miles southwest of Calgary. The aircraft wreckage was found on a mountain ridge at 8900 feet asl some 40 hours later. The flight was in controlled descent to Calgary when the impact occurred. There was a total break-up of the aircraft, and the pilot, the lone occupant, was fatally injured. There was a brief fireball at the time of impact.

The aircraft left Nanaimo, British Columbia, and landed at Penticton Airport at 1232 Pacific daylight time (PDT). The aircraft was fueled with 184 litres of fuel, filling all three belly tanks. At this time, the rear portion of the aircraft cabin was observed to be loaded with luggage and cargo. The pilot/aircraft owner was planning his flight to Calgary (Springbank), Alberta, and spent at least an hour flight planning and talking with the Kamloops Flight Information Centre by telephone. He had some difficulty determining a route to fly to Springbank, because of airspace restrictions due to forest fires, but decided on a routing of Penticton, Kelowna, Vernon, Revelstoke, and Springbank. The aircraft took off from Penticton Airport at 1420 PDT, with the pilot and two passengers on board and crashed approximately seven minutes later in a ravine of Penticton Creek, 11 nautical miles northeast of Penticton Airport. A post-impact fire broke out and consumed most of the fuselage area. The fire caused a small forest fire, seen by a firefighting aircraft crew. There were no radio calls from the occurrence aircraft, and the three occupants were fatally injured.

At 1700 MST, Alberta Citylink flight 933, C-FBIE, a British Aerospace Jetstream 31, serial number 815, took off from Calgary, on a scheduled flight to Lloydminster, Alberta. The aircraft carried a two-pilot crew, 13 passengers, and 250 pounds of freight and baggage. A non-precision automatic direction finder (ADF) approach was conducted to runway 25. The first officer was flying the approach, and when the runway environment became visual, the captain took control, requested 35 degrees of flap, and commenced the final descent to the runway. On touchdown, the left main landing gear collapsed and both propellers struck the runway surface. The aircraft slid along the runway on the belly pod for about 1 800 feet, and when the left wing contacted snow on the edge of the runway, the aircraft turned about 160 degrees. The passengers and crew evacuated through the over-wing exit. There was no fire and no injuries. The Board determined that an unstabilized approach resulted in a heavy landing because the captain changed the configuration of the aircraft, and the high rate of descent was not arrested before contact was made with the runway surface. Contributing to the high rate of descent were the reduction of engine power to flight idle, airframe ice, and the time available for the final descent. Contributing to the damage on landing was the left-to-right movement of the aircraft.

At about 1826 mountain standard time (MST), the aircraft, with the pilot and four passengers on board, departed the Calgary International Airport, Alberta, on a night instrument flight rules (IFR) flight to Hillsboro, Oregon, USA. At about 1946 the aircraft disappeared from the Vancouver Area Control Centre (ACC) radar screen in the vicinity of Castlegar, British Columbia. The Victoria Rescue Coordination Centre (RCC) was notified, and search aircraft were dispatched. Despite bi-national search cooperation and radar fixes of the aircraft's last known position (LKP), a seven-day search failed to locate the missing aircraft. An emergency locator transmitter (ELT) signal was not received. On 14 June 1996, the wreckage was located at latitude 49°14'48"N, longitude 117°03'20"W, at an elevation of approximately 6,700 feet above sea level (asl). The aircraft was destroyed by impact forces and a post-crash fire. The pilot and four passengers were fatally injured.

The aircraft suffered an incident in Ecuador few days prior to this accident and damages were reported to the undercarriage. A ferry flight to Calgary was arranged so the aircraft could be repaired by technicians by De Havilland Canada. The flight from Quito to Calgary was completed with the undercarriage down. Upon touchdown on runway 28 at Calgary Airport, the nose gear collapsed. The airplane slid on its nose and came rest, bursting into flames. In a hurry, both pilots escaped the cabin and did not stop both engines. Hydraulic fluids ignited and the aircraft was totally destroyed by fire. Both pilots were uninjured. Dual registration FAE064 and HC-BFH.

The crew was engaged in a SAR mission after a small plane disappeared. While flying in relative good weather conditions, the aircraft struck the slope of a mountain located in the Kananaskis Park, about 75 km west of Calgary. The aircraft was destroyed and all eight occupants were killed, three crew members and five observers.

Pacific Western Airlines scheduled early morning flight 501 to Edmonton was pushed-back from the gate at 07:35. After engine start the aircraft taxied to runway 34 for departure. Takeoff was begun at 07:42 from the intersection of runway 34 and taxiway C-1. About 20 seconds into the takeoff roll, at an airspeed of approximately 70 knots, the flightcrew heard a loud bang which was accompanied by a slight veer to the left. The captain immediately rejected the takeoff using brakes and reverse thrust. Both the crew members suspected a tire on the left main landing gear had blown. The captain decided to taxi clear of the runway at taxiway C-4. Approaching C-4, the crew a.o. noted that left engine low pressure unit rpm was indicating 0 per cent. Twenty-three seconds after the initiation of the rejected takeoff, the first officer called clear of the runway on tower frequency: "501 clear here on Charlie 4". The purser then entered the flight deck and reported a fire on the left wing. The control tower then confirmed that there was a fire: "Considerable amount off the back - on the left side engine there - and - eh - it's starting to diminish there. Eh - there's a fire going on the left side." One minute and two seconds had passed since the initiation of the rejected takeoff. Immediately after this the purser further stated that "the whole left-hand side, the whole back side of it is burning". The captain discharged a fire bottle into the engine and the first officer requested emergency equipment. At an elapsed time of 1 minute 36 seconds, the cockpit fire warning bell activated. Simultaneously, the purser re-entered the cockpit and reported that it was getting bad at the back. The captain stopped the aircraft the crew then carried out the procedures for an emergency evacuation, which was initiated at an elapsed time of 1 minute 55 seconds. All 119 occupants were evacuated, among them 29 were injured. The aircraft was destroyed.

The crew started the takeoff procedure from a runway contaminated with melted snow. In snow falls, the airplane was unable to gain sufficient speed so the captain decided to abandon the takeoff and initiated an emergency braking maneuver. Unable to stop within the remaining distance, the airplane overran and came to rest few dozen meters further. There were no injuries among the occupants while the aircraft was damaged beyond repair.
