The crew was completing a ferry flight from Tucson to Ogden-Hill AFB. On approach, while descending to a height of 7,000 feet, the crew got a n°2 prop low oil warning. The engine was shut down but the crew was unable to feather the propeller for unknown reason. Despite the situation, the pilot-in-command was able to continue the approach and landed safely on runway 32. After touchdown, the n°2 prop separated from its mount and debris punctured the n°1 fuel tank. The airplane caught fire and came to rest in flames after a course of 4,000 feet. All three crew members escaped uninjured while the aircraft was partially destroyed by fire.

While cruising at an altitude of 9,100 pieds by night and in poor weather conditions, the twin engine airplane struck the slope of a mountain located in the region of Stockton, Utah. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the five occupants was found. On 13 May 1972, walkers found the wreckage in an isolated area. The aircraft was totally destroyed by impact forces and the accident was not survivable.

The airplane was engaged in a cargo flight from Ogden-Hill AFB to Grand Forks AFB, North Dakota, with intermediate stops in Mountain Home, Fairchild AFB (Spokane), Great Falls and Minot, carrying various equipment for the US Army. After liftoff from runway 32, while climbing, the pilot raised the landing gear when the airplane pitched down to 15°. It lost height and struck the ground 8,200 feet past the runway end, slid for about 2,600 feet before coming to rest in flames. All three crew members were injured and the aircraft was destroyed.

During the takeoff roll at Salt Lake City Airport, the crew completed the rotation too early. The aircraft stalled then crashed in flames near the runway. The aircraft was destroyed and both pilots were killed.

While performing a cargo flight, the crew encountered poor weather conditions. The captain decided to make a 180 turn to gain height when the twin engine aircraft struck the slope of a mountain located near Park City. The aircraft was destroyed upon impact and both occupants were killed.

Shortly after takeoff, while in initial climb, both engines failed simultaneously. The captain raised the undercarriage and attempted an emergency landing. The airplane belly landed in a field and came to rest near the airport. All five occupants were injured, one of them seriously. The aircraft was destroyed.

The crew departed Salt Lake City Airport for a local training flight. Three minutes after passing 9,000 feet, still climbing to reach FL130, the crew informed ATC about smoke in the cockpit. Shortly later, the aircraft entered an emergency descent until il crashed in Woods Cross, about 6 miles northeast of the airport. The aircraft owned by Thomas J. Carter was destroyed and both pilots 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.

Flight 227 took off from New York-LaGuardia (LGA) for a flight to San Francisco (SFO) via Cleveland (CLE), Chicago (MDW), Denver (DEN) and Salt Lake City (SLC). The aircraft took off from Denver at 16:54 and climbed to its assigned cruising altitude of FL310. At 17:38 flight 227 began its descent for Salt Lake City. The flight proceeded in accordance with radar vectors. After a radar handoff to Salt Lake City Approach Control new clearance altitudes were given. At 17:47 the approach controller advised, "United seventy twenty seven ... five miles south of Riverton Fan Marker coming on localizer course cleared for ILS runway three four left approach." The pilot replied "Okay we're slowed to two fifty (Knots) and we're at ten (10,000 feet) we have the runway in sight now, we'll cancel and standby with you for traffic." Control of the flight was transferred to the tower and at 17:49:40 landing clearance was issued. The aircraft crossed the outer marker over 2,000 fee & above the ILS glide slope. The rate of descent during the final approach exceeded 2,000 ft/min, approximately three times the United Air Lines recommended rate of descent for landing approaches. The first officer attempted to apply power but the captain stopped him. Power was then applied too late to arrest the rate of descent. The airplane touched down 335 feet short of the threshold of runway 34L. The right and left main landing gear began to separate and the airplane slid onto the runway. Severe upward and rearward impact forces from the right main Landing gear assembly produced a large impact hole and ruptured fuel lines and the no. 3 generator leads between fuselage station 1030 and 1130 on the right side. The fuel was ignited by sparks from the fuselage scraping on the runway and/or the severed generator leads. 13 passengers were uninjured while 35 people were wounded. 43 other occupants were killed.

While in cruising altitude, the pilot informed ATC that both engines failed and elected to divert to the nearest airport. While losing speed and height, the airplane crash landed in a field located in Delta. All three passengers were injured while the pilot was killed.
