Aircraft and operators
The aircraft involved in the accident was a Lockheed L-188 Electra with the serial number 1141, which had been delivered to
Panarctic Oils was a company founded in 1966 to explore for oil deposits in the Canadian Arctic Circle. It was later absorbed into Petro-Canada. To transport employees and equipment, Panarctic Oils initially chartered aircraft from other companies, but soon established its own fleet of aircraft.[1][3]
Flight history
First leg of the flight
Panarctic Oils Flight 416 took off at 6:05 p.m. on October 29, 1974. The Lockheed L-188 Electra departed
Second leg of the flight
The estimated duration of the second leg of the flight was 4 hours and 12 minutes. There were 30 passengers on board, as well as a fourth, male crew member, who acted as loadmaster and flight attendant at the same time on the combined cargo and passenger flight.[1][3]
The Electra took off again from Edmonton at 8:04 p.m. The flight went without any special incidents. As far as Fort Smith, Northwest Territories, the aircraft was flown at an altitude of 18,000 feet (5,500 m), then it climbed to 21,000 feet (6,400 m). In accordance with the schedule, the aircraft flew over Byron Bay in what is now Nunavut at 11:04 p.m. About 100 miles (160 km) further north, the aircraft climbed to an altitude of 25,000 feet (7,600 m). When the aircraft was about 150 miles (240 km) from Rea Point, the crew made radio contact with the landing site. A VOR/DME straight approach to runway 33 was performed. The initiated descent was quiet apart from some turbulence at an altitude of 4,000 feet (1,200 m). When they were at a distance of about 17 miles (27 km) from Rea Point Airfield, the pilots maintained an altitude of 2,000 feet (610 m) for 1 minute and 45 seconds before lowering the aircraft further until it was at an altitude of about 875 feet (267 m) at a distance of 6 miles (9.7 km) from the airfield. The crew contacted the airfield at Rea Point and informed them of their DME distance on the final approach.[1][3]
During the approach, the engine power was adjusted to 1500 hp each. Both
Accident
Looking out of the cockpit window, the flight engineer thought he could see the icy sea. The captain, on the other hand, believed that the aircraft was above a layer of clouds, so he reduced the thrust and pushed the control horn forward, causing significant g-forces to act on the plane. The rate of descent increased rapidly to 1,700 feet (520 m) to 2,000 feet (610 m) per minute. When the aircraft was at an altitude of 200 feet (61 m) and 2 miles (3.2 km) from the runway, the first officer shouted to the captain piloting the aircraft that the rate of descent was too high, to which the pilot did not respond. At an altitude of 50 feet (15 m), the first officer and the flight engineer both called out to the captain again, but again there was no response. The first officer stretched out his hand to the thrust levers on the right side, where the flight engineer's hand was already located. The plane hit the ice. On impact, the cockpit section tore off the fuselage and slid, along with the cargo, 900 feet (270 m) over the ice. The fuselage of the plane sank into the hole created by the impact in the ice surface. After the cockpit section came to a stop on the ice, the flight engineer unfastened his harness. When he straightened up, he saw that the captain and the first officer were still in their seats. Although he was injured, the first officer managed to unfasten his seat belt. The flight engineer managed to pull him onto the ice. Shortly afterwards the ice collapsed around the cockpit section, which then plunged into the water and sank.[1][3]
Victims and survivors
Only the first officer, David Wayne Hatton, and the flight engineer, Garry Douglas Wayman, survived the accident. One passenger, who had initially survived, died on the way to the hospital in
Although the crash site was only 2.5 nautical miles (2.9 mi; 4.6 km) from the end of the runway, it took about two hours from the time of the crash to the arrival of emergency responders. The delay was due to an inadequately defined emergency response procedure. There was no off-airport vehicle on standby, and emergency response following the loss of radio contact with the aircraft was slow to be initiated. However, according to the accident report, it was unlikely that a faster response would have affected the outcome.[3]
Reactions
In a 4 November 1974 article in the Medicine Hat News, the crash site in the Arctic Ocean was described as the "worst place for an (aviation) accident" in icy conditions.[4] The island is located about 700 kilometres (430 mi) from the Canadian mainland, within a radius of hundreds of kilometers there are only Arctic Ocean and polar steppe, most areas are uninhabited, professional medical infrastructure was non-existent in the region, and the nearest major cities with professionally equipped trauma clinics are thousands of kilometers away. The distance to Edmonton, where the originally rescued passenger was to be transferred, is more than 2,400 kilometres (1,500 mi). The weakened accident victims, with their potentially survivable injuries, were exposed to extreme cold and rapid first aid could hardly be provided.
Cause of accident
A 60-page report on the accident was published. The following accident factors were reported:[3]
- The approach continued below the minimum descent altitudepermitted by the airline;
- the pilot in charge reacted inappropriately to a visual cue and suddenly initiated the last rapid descent; this descent was described as "irrational";[3]
- the excessively high rate of descent was not corrected due to the partial incapacitation of the pilot-in-charge;
- crew resource management in the final stages of the flight was inadequate;
- no flight operations manual or similar document had been provided by the carrier that would adequately set out the duties and responsibilities of the flight crew;
- the flight was operated in accordance with the operating regulations for private and not commercial flights;
- the emergency response at Rea Point Airfield was inadequate.
