Incident Overview
A private pilot was conducting a night cross-country flight at 2,500 feet with flight following services from air traffic control. During the flight, the engine began to sputter unexpectedly. The pilot cycled the throttle control several times but the engine continued to run at approximately 700-800 rpm without response to throttle adjustments. The airplane subsequently began a rapid descent, prompting the pilot to execute a forced landing onto a highway.
Collision and Fire
During the landing, the airplane's right wing struck a tree and the ground. After the airplane came to a stop, the pilot observed that a fire had started. The pilot attempted to assist the passenger in exiting the aircraft but was unable to do so due to the fire and had to evacuate the airplane for safety.
Post-Incident Examination
Following the incident, an examination of the airframe, flight controls, engine assembly, and accessories was conducted. No anomalies or mechanical malfunctions were identified.
