Accident Overview
On final approach to Moline-Quad City Airport, the aircraft was arriving from Hutchinson, Georgia, with Atlanta as its intended destination. During the approach, both engines lost power. The airplane subsequently lost speed, entered a stall, and impacted terrain short of the runway. The aircraft was destroyed, and the pilot, who was the sole occupant, was killed.
Probable Cause and Contributing Factors
The official investigation determined the probable cause to be a loss of control on approach due to improper operation of the powerplant and powerplant controls. Several contributing factors were identified:
- Improper operation or failure to use anti-icing/deicing equipment.
- Induction system ice.
- Failure to maintain flying speed.
- Conditions conducive to carburetor or induction system icing.
- Partial loss of power on both engines.
- Obscuration (reduced visibility).
- Visibility of 1/2 mile or less.
- Wind gusting to 22 knots.
- Ram air hoses blocked by cakes of ice and snow.
- Buildup present in the carburetor chamber.
The combination of these factors led to the loss of engine power and subsequent loss of control, resulting in the crash.
