Flight Details
A student pilot completed a dual instruction flight and received permission from the flight instructor to conduct a solo flight. The instructor advised the student to remain within 5 miles of the departure airport. However, the student strayed beyond this distance.
Sequence of Events
During the flight, the instructor established radio contact with the student pilot, who reported that he did not know his location. While descending from 3,500 feet to 2,000 feet approximately 7 miles southeast of the airport, the student applied carburetor heat. Shortly thereafter, the engine began to run rough. The student then turned off the carburetor heat, after which the engine lost power.
The student pilot subsequently stated that he did not leave the carburetor heat on long enough to dissipate accumulated ice.
Aftermath
The student performed an off-airport landing. No further details were provided regarding aircraft damage or injuries.
