A twin-engined Beechcraft 1900C turboprop crashed 10 miles east of Aleknagik, Alaska on 8 March after impacting rising terrain, a preliminary report from the US National Transportation Safety Board (NTSB) shows.
The aircraft, with tail number N116AX, was operating as Flight 51 on behalf of Part 135 carrier Alaska Central Express, a cargo airline.
The captain and first officer on the flight sustained fatal injuries, and the aircraft was destroyed, according to the preliminary report.
The flight departed Anchorage at 5:44 local time and had made a stop at King Salmon, Alaska before continuing to Dillingham, Alaska. Flight crew were cleared to begin an approach into Dillingham and instructed to maintain an altitude of 2,000ft (609.6m) or above. Air traffic control then permitted the aircraft to enter a holding pattern to obtain a runway conditions report upon the flight crew's request. The aircraft subsequently lost contact with radar.
Overcast weather conditions were present with light rain and 17kt (31.5 km/h) winds, with gusts up to 30kt (55.6 km/h), a weather report populated near the crash site states.
The NTSB and US Federal Aviation Administration examined the site of the accident on 9 March.
