What happened
Shortly after departing from Iliamna, an single engine airplane experienced a loss of airspeed that prevented the pilot from maintaining necessary flying speeds. The aircraft entered a stall and impacted a field covered in snow. Despite the impact resulting in the total destruction of the airframe, all eight occupants managed to exit the wreckage with only minor injuries.
Findings
Investigations into the accident identified that the aircraft stalled during its cruise phase because the pilot was unable to sustain sufficient velocity. Several environmental and operational factors contributed to the loss of control:
- The flight continued under Visual Flight Rules (VFR) despite encountering IFR weather conditions.
- Visibility was significantly reduced, measured at two miles or less.
- The presence of snow and atmospheric conditions likely led to icing within the carburetor or induction system.
- Improper in-flight decision making and inadequate planning were noted as contributing elements to the accident.
