The crew was engaged in an anti-submarine mission off the coast of Trinidad Island. The aircraft crashed into the sea off the Island in unknown circumstances, but most probably during or after an engagement with enemy submarine. SAR operations did not find any trace of the aircraft nor the 12 crew members based at Waller Field, Trinidad.

The crew was engaged in an anti-submarine patrol flight over the Atlantic Ocean. En route, the German submarine U-572 was spotted, cruising some 550 km off the Guyana coast. The crew of the Mariner attacked the submarine that was sunk. But it seems the Mariner was shot down as well and crashed into the sea at 11°35' N 54°06' W. No trace of the aircraft nor the crew was found.

The seaplane was engaged in a crew familiarization exercise out of Norfolk-Chambers Field NAS. As takeoff run began, a slight porpoising developed, but was corrected. Before flying speed could be gained, the aircraft bounced into the air about 25 feet and then settled back on the water. It bounced a second time to a height of about 100 feet and then crashed into the water from a steep dive. Seven crew members were killed and five others were injured.

The seaplane was engaged in a local training exercise at San Juan with a crew of seven on board. At the time of the crash, the pilot-in-command was in the midst of his training for the designation of Patrol Plane Commander. His airplane was observed to make a succession of bounces and from the last bounce dive into the water at a steep angle. The direction of takeoff was approximately 30-40° out of the wind. On a previous attempted takeoff the pilot had found the plane tail heavy and upon taxiing back for another try had released his load so that the plane was nose heavy. After liftoff, the airplane nosed down and plunged into the sea. Three crew members were killed and four others were rescued.
