A float-equipped de Havilland Canada DHC-3T Turbine Otter, N725TH, crashed in Mutiny Bay, Washington. All ten occupants were killed in the accident.

The accident flight departed from Friday Harbor Seaplane Base, Washington, about 14:50 with a destination of Renton Municipal Airport (RNT), Washington. Track data indicated the airplane flew at an en route altitude of 650 to 975 ft above mean sea level (msl), and the groundspeed was between 115 and 125 knots. At 15:08:43 the altitude increased to 1,125 ft, and the groundspeed reduced to 109 knots. At 15:08:49, the altitude decreased to 875 ft and the groundspeed reduced to 100 knots. The tracking data ended at 15:08:51, at an altitude of 700 ft and groundspeed of 55 knots.

Witnesses near the accident site reported that the airplane was in level flight before it entered a slight climb, then pitched down in a near-vertical descent. The airplane continued in a nose low, spiraling, near-vertical descent until it impacted water in Mutiny Bay.

The wreckage was located a week later, at a depth of 190 feet.
