What happened
During a climb following departure from Anchorage Airport, the pilot experienced significant malfunctions with the onboard flight instruments. The aircraft was operating in conditions characterized by heavy fog and dense cloud cover, which resulted in zero visibility. As the technical issues progressed, the aircraft lost altitude and eventually impacted the terrain a short distance from the airport. The impact resulted in the destruction of the aircraft and caused the deaths of all seven occupants.
Findings
Investigations into the accident identified several contributing elements related to equipment failure and environmental conditions. A primary factor was the malfunction of the fluxgate compass, which led to a controlled flight into terrain. The investigation noted that the flux detector wires had become chafed, representing a material failure within the navigation system.
Environmental factors played a critical role, as the flight was conducted amidst rain, fog, and extremely low ceilings. Additionally, several operational challenges were identified:
- The pilot's use of miscellaneous equipment was deemed incorrect or insufficient.
- Air traffic control failed to accurately identify the aircraft on radar.
- There was a lack of direct communication between ground control and departure control.
- The aircraft was observed using an IFR arrival transponder code after its initial departure.
