Circumstances:
While parked at Roanoke-Woodrum Airport, all passengers embarked when the undercarriage failed. The airplane sank on its belly. All 42 occupants were evacuated safely and the airplane was later considered as damaged beyond repair.
Probable cause:
Improper maintenance by the maintenance personnel as the hydraulic reservoir, lines and fittings were not properly serviced. Investigations revealed the landing gear pin was not in. On hydraulic test, ground handle moved up due to excessive clnc in sel valve and air hydraulic system.

Circumstances:
The crew departed Floyd Bennett Field Airport in New York on a flight to Moffett Airbase, California, with an intermediate stop at Glenview Airport, Illinois, under call sign PE-05. At 2035LT, while cruising at an altitude of 22,000 feet, the crew informed ATC about his position. Shortly later, the airplane entered a spin, crossed the last cloud layer at an altitude of 3,000 feet in a right turn and struck the ground in a 60° nose down attitude at a speed of 800 km/h. The aircraft disintegrated on impact and all four crew members were killed. The wreckage was found seven miles northeast of Battle Creek.
Crew:
Lt William E. Xiques, pilot,
Lt John P. Fitzmaurice III, copilot,
ADJ2 Charles J. Lurvey, flight engineer,
ADJ3 Larry W. Battson, flight engineer.
Probable cause:
Investigations determined that there was no in-flight fire and no major structural failure had occurred. The plane was only about a year old at the time of the accident. The only clues were unintelligible voice transmissions at 2037 and again at 2039. The voice was masked by extreme high frequency background noise. Despite attempted computer analysis of the voice and an extended accident investigation, the cause was never determined. It was believed that some kind of catastrophic failure had occurred that incapacitated the crew. It was also surmised that it was possible that the windshield failed in-flight under decompression forces causing sound comparable to high velocity air in the cockpit. Not enough of the windshield was recovered to perform an analysis and come to any conclusions about this possibility.

Captain / Total flying hours:

Circumstances:
Shortly after takeoff from Gulfport-Biloxi Airport, while in initial climb, the right engine failed. The copilot informed ATC about his situation and was cleared to return for an emergency landing. Shortly later, the airplane stalled and crashed in Long Beach, southeast of the airport. A pilot and a passenger were killed while 10 other occupants were injured. The aircraft was destroyed.
Probable cause:
Failure of the right engine due to the failure of the number 3 piston ring caused by an oil starvation. This was the result of an inadequate maintenance and inspection.
The following factors were considered as contributing:
- Failed to obtain/maintain flying speed,
- Improper in-flight decisions or planning,
- Improper operation of powerplant,
- Poor crew coordination,
- Improper emergency procedures,
- Right propeller was not feathered.

Probable cause:
In-flight collision caused by an inadequate visual contact to avoid collision on part of the crew.

Due to overload failure, several parts of the airplane separated and it eventually crashed in an open field located near South Haven. The pilot, sole on board, was killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it is believed the loss of control was the result of a temporary pilot incapacitation.

Circumstances:
The pilot, sole on board, was completing a cargo flight to Milroy, Pennsylvania. While on approach in poor weather conditions (low ceiling and rain), both engines failed simultaneously. Unable to maintain the prescribed altitude due to an insufficient speed, the pilot attempted an emergency landing in an open field when the aircraft crashed few miles from the airport. The aircraft was destroyed and the pilot was injured.
Probable cause:
Double engine failure on approach due to a fuel starvation caused by a mismanagement of fuel and inattentive to fuel supply on part of the pilot.
