The crew was engaged in a local training flight and was supposed to complete touch-and-go maneuvers. After touchdown, the pilot-in-command increase the engine power to takeoff when the airplane went out of control, veered off runway and came to rest. All four crew members escaped uninjured while the aircraft was damaged beyond repair.

On a Sunday night search and rescue case the aircraft and crew responded to a request for assistance from a fishing vessel reportedly taking on water 20 miles off the coast. The same plane and crew had just returned from another search of over six hours. The entire crew perished when their seaplane struck the water while attempting to deliver a dewatering pump to a sinking vessel. No trace of the aircraft nor the six crew members was found.

This HU-16E crew was performing a scheduled logistics/law enforcement mission to the Loran Station on St. Paul Island. When then arrived they encountered poor weather with a ceiling below 400-feet with light snow falling. With insufficient fuel available to reach an alternate airfield, the pilot attempted to land at the strip. On the fourth attempt to land, the plane crashed when the right wing tip struck the ground. AT2 Frank R. Edmunds was fatally injured as a result.

The crew was performing a test flight after the aircraft had undergone an intermediate inspection in which the control columns were removed and inspected for fatigue cracks in the bottom casting. The plane was cleared for take-off and instructed to turn right immediately after take-off to avoid other traffic. Take-off was normal but immediately after leaving the runway the plane banked slightly to the left, hesitated, and then banked and then banked very rapidly to the left until it was in a 90° bank. The left wing tip struck the ground and the plane broke in two and crashed. Four crew members were killed while two others were injured.
Those killed were:
Lcdr Claude S. Labaw,
Lt Rolland A. Faucher,
