A pilot reported an engine RPM drop to 1000-1200 at 200 feet after a normal pre-takeoff check. Fuel tank switch did not restore power. Forced landing in a field resulted in soft terrain encounter during roll, and a post-impact fire destroyed the airplane. Investigation found no mechanical malfunction but engine fire damage.

Incident Overview

The pilot reported that prior to takeoff, all indications appeared normal. Shortly after departure, at an altitude of approximately 200 feet, the engine RPM dropped to between 1000 and 1200. The pilot attempted to switch fuel tanks in an effort to restore power, but the change did not resolve the RPM loss.

Forced Landing

In response to the power loss, the pilot initiated a forced landing in a field. During the landing roll, the airplane encountered soft terrain, which affected the landing. A post-impact fire ensued and subsequently destroyed the airplane.

Investigation Findings

Post-accident investigation revealed no evidence of mechanical malfunction. The engine was extensively damaged by the fire, which limited the ability to conduct a thorough examination. The investigation did not identify a specific cause for the RPM loss.
