On the day of the accident, the aircraft departed from Anchorage at 15:15 AST and was due to land at
Unalaska two hours and 15 minutes later. While descending toward Unalaska, the crew received clearance for an
RNAV approach to Runway 13, a runway. As the aircraft approached the airport, the wind changed from 210 degrees at to 180 degrees at , but was reported as 270 degrees at . The aircraft became unstable and a
go-around was executed. The flight returned for a visual approach onto Runway 13. The wind speed increased and the controller reported that winds were 300 degrees at . According to the investigation report, the pilots believed there was a crosswind during the landing approach, based on seeing waves by the nearby shore and a
windsock near the runway, but in contradiction to the weather control report and onboard witness statements. The crew decided to continue with the landing and touched down at 17:40. The aircraft landed down the runway with
reverse thrust and wheel-braking inputs by the captain. When the aircraft reached , maximum braking was applied. As an overrun was imminent, the pilots steered the aircraft right to avoid going into the water past the runway end. Attempts to stop on the paved runway surface failed, and the aircraft crossed a section of grass and then broke through a chain perimeter fence and crossed a ditch. The aircraft struck a large rock, crossed a public roadway and finally came to a stop on the shore of
Iliuliuk Bay. The port wing or propeller struck a signal post, the port propeller struck a yellow diamond shaped road sign, and again struck
rock riprap as the plane came to a halt. This caused the port-side (left) propeller to shatter, sending debris and large pieces of the propeller blade into the fuselage. One of the blades was found inside the cabin. Two passengers were critically injured and another 10 had to receive medical care. David Allan Oltman died a day later. ==Investigation==
