Synopsis

West Coast Airlines Flight 720 was operated on Friday, March 10, 1967 by a Fairchild F-27 aircraft registered N2712 and built in 1960. That morning, the aircraft was parked in West Coast's hangar at Klamath Falls Airport for routine maintenance. [4] Because of snowy conditions, instead of loading at the terminal, as was standard procedure, the aircraft was loaded in the hangar with the passenger and crew members. Both pilots performed a preflight check of the plane and reported nothing unusual.

After boarding was completed at 4:46 a.m. PST, the plane was pushed out of the hangar as snow, mixed with rain, was falling. [4] During pushback, the tractor tug became immobilized in the snow. Ground personnel spent 11 minutes freeing it, and during this time, the airplane was exposed to the adverse weather conditions and no attempt was undertaken to clear the wings or control surfaces of snow. Once freed from the snow, the aircraft taxied to Runway 14 and was granted takeoff clearance at 4:57 a.m. The elevation of the airport is approximately 4,100 feet (1,250 m) above sea level.

The aircraft took off at 5:01 a.m., and at 5:02:43 the crew contacted the tower to confirm that the plane was visible via radar. This was the last communication from the aircraft. The controller replied to the crew that they were indeed visible via radar, and he then witnessed a target on his screen drift to the left of the runway centerline and head toward the 6,526-foot (1,989 m) Stukel Mountain, four miles (6 km) southeast of the airport. At 5:02:49, the flight impacted the mountain's northwest slope at an approximate elevation of 5,050 feet (1,540 m). [4]

Cause and investigation

At 5:09 a.m., a report reached the tower that an aircraft had crashed on Stukel Mountain. The runway tracks were observed in heavy snow, and the plane had swerved to the left on the runway before becoming airborne. By takeoff, the left gear was 12 feet (3.7 m) off the runway. [4]

Several witnesses in the vicinity saw the airplane flying low and saw or heard a large explosion. All reported snow at the time of the crash. [5]

The aircraft was equipped with a flight data recorder (FDR). Although the FDR was damaged in the crash, its recording medium could be read. The aircraft was reported to have climbed for approximately one minute after takeoff. Throughout the flight, the aircraft was recorded to have continued a turn to the left of the assigned heading. Shortly before impact, the aircraft began a sharp turn to the left, toward the mountain, at heading of 042 degrees.

The aircraft was equipped with a cockpit voice recorder (CVR). Although the device was damaged, the recording was intact. The crew reported a loss of control before impact and reported that they could not see the mountain. An expletive was uttered just before impact. [4]

The aircraft was observed accumulating ice and snow on its control surfaces prior to takeoff and when moved out of the hangar. The investigation concluded that the failure of the crew to de-ice the plane was the cause of the accident. [6] Given the crew's short turnaround schedule, fatigue was suggested as a contributing factor.

The impact and the resulting fire killed all 248 people on board the KLM plane and 335 of the 396 people on board the Pan Am plane, with only 61 survivors in the front section of the latter aircraft. With a total of 583 fatalities, the disaster is the deadliest accident in aviation history.

As Flight 1493 was on final approach, the local controller was distracted, though air traffic was not heavy at LAX, by a series of abnormalities, including a misplaced flight progress strip and an aircraft that had inadvertently switched off the tower frequency. The SkyWest flight was told to taxi into takeoff position, while the USAir flight was landing on the same runway.
