Aviation Accident Summary CHI01LA125

Brussels, IL, USA

Aircraft #1

N38646

Piper J5A

Analysis

The airplane nosed over during a precautionary landing. The pilot reported he was practicing a simulated emergency landing approach. He reported he had pulled out the carburetor heat during the simulated emergency landing and cleared the engine during the approach. He terminated the maneuver at 300 feet above ground level (agl). When he advanced the throttle there was no response for a "short period of time, then a halting or missing response." He reported the engine made a "hesitating acceleration." The airplane was about 200 feet agl and he made a decision to land and check the fuel and engine. The airplane touched down at 65 mph. He reported the vegetation was much taller than he perceived, and the airplane decelerated rapidly and nosed over. The engine was examined and exhibited no preexisting anomalies. The engine was tested and it ran between idle power and 2,600 rpm's.
