The pilot’s improper decision to continue flight in an area of moderate-to-heavy icing conditions, which resulted in exceedance of the airplane’s anti-icing system capabilities, a degradation of aircraft performance, and subsequent aerodynamic stall.

The noninstrument-rated pilot’s intentional flight into instrument meteorological conditions, which resulted in spatial disorientation and loss of airplane control.

The student pilot’s unintentional selection of raising the landing gear instead of the flaps during a touch-and-go landing, and the flight instructor’s delayed remedial action, which resulted in the landing gear retracting during the landing roll.

Water contamination of the airplane’s fuel supply which resulted in a total loss of engine power.

Inadequate maintenance at the time the carburetor was replaced, which resulted in the improperly installed throttle cable and a partial loss of engine power. Contributing to the accident was an inadequate annual inspection that failed to detect the improper throttle cable installation.

A loose stand-off clamp which resulted in a throttle assembly malfunction, and the inability of the engine to produce full power during the attempted takeoff.

The pilot’s loss of situational awareness, and his unintended landing on a soft unimproved dirt road, which resulted in a loss of directional control into soft ground and the airplane to subsequently nose over.
