What happened
On the day of the accident, the pilot contacted Flight Service Station (FSS) eleven times to request weather updates. Although initial conditions were below the minimums required for a commercial passenger flight in a single-engine airplane, the pilot later departed using a special VFR clearance after weather conditions had slightly improved. During the flight, the pilot conducted two approaches at the destination airport while operating in instrument meteorological conditions (IMC), utilizing available GPS-based approaches. Witnesses and weather records confirmed that the area was characterized by low clouds, with tops at 1,000 feet, and limited visibility.
Following the second approach, the pilot communicated via radio that a return to the departure airport was necessary because the destination airfield was not visible. No engine irregularities or distress signals were reported prior to the loss of contact. The aircraft was later tracked flying north of the airport and away from the departure point at an altitude below the 2,200-foot radar coverage limit. The aircraft eventually struck the frozen Arctic Ocean in a right bank with a 60-degree nose-down attitude, approximately three miles from the site of the final radio transmission. The crash resulted in all occupants being fatalities.
Findings
An inspection of the wreckage, conducted before the plane sank through the ice, showed no evidence of mechanical failure prior to the impact. The propeller was found to be at a power setting appropriate for maneuvering airspeed, and the autopilot was not engaged at the time of the crash. However, the aircraft was found to be over its maximum gross weight and was carrying a nearly full load of fuel. Small amounts of clear ice were noted on parts of the tail surfaces. Evidence suggests that the pilot may have been influenced by internal or passenger pressure to complete the mission despite the challenging weather.
