Provo

While taking off from Provo Airport runway 13/31, the airplane went out of control and crashed. Both passengers escaped with minor injuries while both pilots were seriously injured. One of them died from injuries sustained. The airplane was destroyed. It was snowing at the time of the accident.

During a cross country flight, the pilot failed to plan for the effects of known adverse weather, including strong winds aloft and mountain wave activity. The pilot overflew several possible fuel stops, continuing on toward the destination until the fuel was exhausted. The airplane collided with heavily wooded terrain after the loss of power to both engines.

While taking off, the aircraft climbed approximately 100 to 200 feet, then began loosing altitude. During a forced landing on a street, it hit a parked car and a light pole and burst in flames. The pilot, who later expired, said that neither engine developed full power (2575 rpm). He said this was not unusual when power was 1st applied, but said full rpm was generally obtained shortly after the roll was begun. After being committed for takeoff, both rpm's were reportedly between 2,300 and 2,400 rpm. Several witnesses stated the engines sounded like they were running rough. A witness reported the aircraft swerved 'as tho the pilot had difficulty with the left engine.' Reportedly, the pilot 'dropped some more flaps' below the 20° takeoff setting 'in order to pull it off' and raised the gear immediately after liftoff. Engine teardowns revealed excessive spark plug gaps, 1 magneto on the right engine had a .008 point gap (.016 required), its #1 and #4 distributor blocks were cracked and the #1 and #6 leads would not fire properly. Hartzell f-6-5a prop governors installed in place of f-6-35a. Aircraft was approximately 348 lbs over max weight limit. All five occupants were killed.

The pilot started the approach to Provo Municipal Airport by night. Due to limited visibility, he was unable to locate the runway as the lights were off. On final, the twin engine airplane crashed in a swamp located near the airport and was destroyed. Both occupants were killed.

Few minutes after takeoff from Provo Airport, while climbing in marginal weather conditions and limited visibility, the twin engine airplane struck the slope of a mountain located near Spanish Fork, few miles southeast of Provo. The wreckage was found four days later, on January 13. All five occupants were killed.

While in cruising altitude, the pilot encountered problems with the left propeller and lost control of the airplane that dove into the ground and crashed in Roosevelt. The aircraft was destroyed and both occupants were killed.

The airplane was on a charter flight from Salt Lake City to Albuquerque with an intermediate stop at Provo, carrying football supporters. Four minutes after its departure from Salt Lake City Airport, the crew encountered poor weather conditions when, at an altitude of 5,500 feet, the airplane struck the slope of a mountain located 22 miles south of Salt Lake City. The wreckage was found 11 feet below the summit (5,449 feet) and was destroyed upon impact. All 13 occupants were killed, among them the captain Garth Edde who founded Edde Airlines in 1960. At the time of the accident, the airplane was one mile east of the intended track.

While on a cargo flight from Salt Lake City to Rock Springs, the crew encountered poor visibility due to foggy conditions. Too low, the airplane impacted ground and crashed on the slope of a mountain located near Provo. The aircraft was destroyed and both pilots were seriously injured.
