The approach to runway 18 was completed in marginal weather conditions. On final, the aircraft was well above the glide and with an excessive speed. It landed half way down the runway and after touchdown, was unable to stop within the remaining distance, overran, went through a fence and down an embankment before coming to rest with the cockpit crushed on the opposite embankment and partially submerged in a drainage ditch. The aircraft was written off and three crew members, among them both pilots, were killed.

The crew was performing a cargo flight from Washington DC. Enroute, he encountered poor weather conditions with snow falls and decided to divert to Knoxville Airport. Unfortunately, the pilot was unable to locate the airfield and decided to return to the capital city. While cruising in a snowstorm, the crew decided to make an emergency landing, reduced his altitude and belly landed on a golf course located in Bluefield. All eight occupants were unhurt while the aircraft was damaged beyond repair.

Following an uneventful flight from Philadelphia, the crew started the descent by night to La Guardia Airport in unfavorable weather conditions. A first attempt to land was aborted and during the second one, the aircraft was too high when it passed over the runway threshold. The captain reduced engine power and the initial contact with the runway occurred well down on runway at an airspeed considerably above the stalling speed of the aircraft. The aircraft bounded approximately 20 feet in the air and remained airborne for several hundred feet before again contacting the runway. After another shorter bounce, the aircraft remained on the runway and brakes were applied in an attempt to stop. However, due to the airspeed, which was still relatively high, and the snow and slush which covered the runway, little deceleration was accomplished. The aircraft continued off the end of the runway, demolished a small wooden building which housed the localizer transmitter, and came to rest in the Flushing Bay, approximately 200 feet beyond the field boundary. The aircraft was destroyed, 13 occupants were rescued while a passenger was drowned.

The crew was performing a flight from Augusta-Bush Field, Georgia, to Morrison AFB in West Palm Beach. Enroute, he encountered engine trouble and the captain elected to divert to Jacksonville Airport. On final approach, the aircraft stalled and crashed short of runway. A crewman was killed while the second occupant was injured. The aircraft was destroyed.

While on a ferry flight from CGAS Biloxi to NAS Seattle for overhaul, the pilot reported an oil leak in the right engine. He then reported a single engine operation and requested an emergency clearance to Fort Worth. The aircraft proceeded out the north leg of the Fort Worth range where the other engine stopped due to an unknown cause, and the propeller was feathered. The aircraft emerged from the clouds in a spin to the left and impacted the ground. All seven crew members were killed and the aircraft was destroyed by impact forces.

The crew was performing a flight from Fargo to Billings with 21 veterans on board. In flight, the weather conditions at destination worsened and visibility dropped from 10 miles to half a mile due to heavy snow storm. On final approach to Billings Airport, the aircraft was too low, hit a tree and crashed in flames in a snow covered field, 400 meters short of runway threshold. Both pilots and 17 passengers were killed, four others were seriously injured. Those killed were:

Enroute, the crew encountered unknown technical problems with the engines while cruising in poor weather conditions. Shortly later, the twin engine aircraft hit a mountain slope locate about 7 miles east of Mt Saint Helens. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. The wreckage was located by walkers in early 1960.

The aircraft departed Palm Springs in VFR conditions but while approaching the Sacramento area, the crew should continue in IFR mode. While descending to McClellan AFB, pilots were unable to locate the airport and were unaware of their exact position when the aircraft hit tree tops and crashed on a wooded mountain located three miles northwest of Auburn, about 20 miles northeast of the McClellan AFB. All three crew members and six passengers were killed while 16 other occupants were injured.

The crew was performing a night training mission and shortly after takeoff from the bay off Corpus Christi NAS, while climbing to a height of 400 feet, the aircraft collided with another Mariner registered 01710 and carrying a crew of 15. This second aircraft was approaching Corpus Christi NAS to land when the collision occurred. Both aircraft went out of control and crashed into the Gulf of Mexico, some 2,5 miles offshore. On the first Mariner, there were no survivor among the 12 occupants. On board the second Mariner, five crew members were rescued while all ten other occupants were killed.
