During a solo session, a student pilot attempted a practice forced landing. Late application of carburetor heat caused icing, preventing recovery. The airplane struck trees after a forced landing to a road was aborted due to traffic.

Incident Details

A student pilot, flying solo, initiated a practice forced landing during a session. The weather conditions were visual meteorological conditions (VMC), with a temperature of 45°F and a dew point of 28°F. These conditions were consistent with serious carburetor icing potential at a glide power setting.

Circumstances

The student pilot attempted to recover from the practice forced landing by simultaneously advancing the throttle and applying carburetor heat. Because the application of carburetor heat was late, carburetor icing formed. As a result, the recovery from the practice forced landing could not be accomplished.

A forced landing was attempted to a road, but vehicular traffic on the road forced the pilot to change landing sites. The airplane subsequently contacted trees and descended out of control to ground impact.

Probable cause

The late application of carburetor heat during a practice forced landing recovery, which allowed carburetor icing to form, preventing the recovery from the practice forced landing.
