Hit the ice and crashed on Thurston Island, Antarctica. Three crew members were killed and six others were rescued 13 days later.

Shortly after takeoff from Corpus Christi NAS, while in initial climb, the seaplane stalled and crashed, killing all five crew members. They were performing a ferry flight to Seattle.

While cruising in poor weather conditions, the seaplane hit the slope of a mountain on Mindoro Island, killing all 11 crew members.

The crew left Banana River NAS at 1927LT on a SAR mission, looking for five TBM Avenger that did not return to their base. Three minutes after departure, the contact was already lost. Twenty minutes later, while cruising at low height, the aircraft went out of control and crashed in a huge explosion into the Sargasso Sea, about 30 miles off New Smyrna, Bahamas. On site, the rescuers did not find any survivors among the 13 occupants.

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.

The crew was performing a night training mission and while on approach to Corpus Christi NAS at a height of 400 feet, the aircraft collided with another Mariner registered 69113 and carrying a crew of 12. This second aircraft just took off from the bay when the collision occurred. Both aircraft went out of control and crashed into the Gulf of Mexico, some 2,5 miles offshore. On board the first Mariner, five crew members were rescued while all ten other occupants were killed. On the second Mariner, there were no survivor among the 12 occupants.

Shortly after takeoff from Chimu Wan NAS, while climbing, the Mariner collided with a USAAF Grumman J2F Duck and crashed into the Bay. All 12 crew members were killed.

While performing a night training mission off San Diego, the pilot lost control of the aircraft that dove into the sea and sank. There were no survivors.

While conducting a night maritime patrol flight, the seaplane apparently crashed into the Sea off the Kerama Islands. No trace of the aircraft nor the 12 crew members was found. It is believed the aircraft was shot down by enemy fire.
