Circumstances:
The crew initiated the descent to Pittsburgh-Allegheny County from the southeast in poor weather conditions. While descending to the altitude of 3,800 feet south of Uniontown, the aircraft impacted the slope of Mt Chestnut Ridge located 5 km from Fairchance. A stewardess and a passenger were seriously injured while 12 other occupants were killed.

Probable cause:
Blamed for the accident was poor judgement on the part of the pilot-in-command for flying by reference to the ground after having descended through the overcast and over the hazardous terrain without determining his position. His failure to follow the radio range course while operating in IMC violated both his company’s and US Department of Commerce’s regulations. An additional factor was that NC13721 had encountered crosswind drift, and at the time of impact had been about 15 NM south of the intended track, its crew apparently unaware of the discrepancy. No evidence was found of any prior mechanical failure in the aircraft or malfunctioning of the ground navigational aids. Subsequent to this crash, the Department of Commerce modified the Pittsburgh radio range, discontinuing the simultaneous voice broadcasts, moved the loop-type radio range beacon from that location to Akron, Ohio, and increased the power at the station located at Buckstown, Pennsylvania.

Circumstances:
The airplane departed Albuquerque Airport at 1231LT and climbed to 9,300 feet. While the crew was trying to change the fuel feed to the left auxiliary tank, the left engine failed. Shortly later, the right engine failed as well. The crew reduced his altitude and attempted to make an emergency landing. Unfortunately, the aircraft was cruising over a wooded area. It impacted trees and crashed in a rocky field located some 48 km east from Albuquerque. All 11 occupants were injured and the aircraft was damaged beyond repair. The failure of the engines was found to be due to the presence of a large amount of water in the 80 octane fuel with which the plane had been serviced at Albuquerque Airport. A check of the fuel storage system at Albuquerque disclosed that on 5,000 gallon underground tank contained about 200 gallons of water. After extensive tests, it was found that with a certain amount of water in the fuel pit, pumping fuel from the underground storage tank would cause water to syphen from the fuel pit into the tank through an air vent running between the two. On the afternoon of the preceding day there had been an unusual amount of rainfall which had flooded the concrete apron and filled the fuel pit with water.
Probable cause:
It is the opinion, of the Accident Board that the probable cause of this accident was an abnormal amount of water in the left main fuel tank of the aircraft due to accidental entry of water into an underground fuel storage. The manner in which water got into this underground tank was very unusual and immediate steps were taken on all air lines to prevent a recurrence.

Circumstances:
While cruising 10 km west from Macon, Missouri, the crew encountered poor weather conditions and was unable to contact the base in Kansas City. In low visibility due to fog, the crew was unable to fix his position and attempted to make an emergency landing in an open field. The aircraft impacted ground and crashed. Both pilots and three passengers were killed, among them Bronson M. Cutting, Senator of New Mexico.
Probable cause:
It is the opinion of the Accident Board that the probable direct cause of this accident was an unintentional collision with the ground while the airplane was being maneuvered at a very low altitude in fog and darkness. The probable contributory causes of this accident were:
- A forecast by the United States Weather Bureau which did not predict the hazardous weather that developed during the latter part of the forecast period.
- Improper clearance of the airplane from Albuquerque by the company's ground personnel because of their knowledge that the plane's two-way radio was not functioning on the Western night frequency.
- Improper control by the company's ground personnel at Albuquerque for not calling the airplane back or ordering it to stop at an intermediate point when it was found that two-way radio communication could not be established.
- Error on the part of the pilot for proceeding in the flight after discovering that he was unable to effectively communicate with the ground.
- Failure of the company's ground personnel at Kansas City to expeditiously redispatch the airplane to a field where better weather existed when it became apparent that the ceiling at Kansas City was dropping to and below the authorized minimum for landing and while the airplane still had sufficient fuel to meet the Department of Commerce requirement of 45-minute fuel reserve after effecting a landing.

Circumstances:
The pilot was performing a night mail/cargo flight. During the stop in Pittsburgh, he was informed by ground staff about the poor weather conditions and icing accumulation on wings and fuselage. The takeoff run was long and the rotation was completed late, after the aircraft rolled all away down the runway. During initial climb, while flying at a height of some 200 feet, the aircraft made a turn to the left and spiraled to the ground. The pilot was killed and the aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
It is the opinion of the Accident Board that the probable cause of this accident was poor judgement on the part of the pilot for attempting to take off under existing weather conditions and on the part of the Company for permitting the takeoff.
