Accident Narrative
The pilot was conducting an instructional flight in aerial application. After completing a simulated swath run, the pilot executed a turn-around maneuver. During this turn, the engine reportedly ceased operation without any warning, and the propeller stopped rotating. The pilot then performed a forced landing, aiming to glide to an open field. However, before the aircraft could reach the field, it collided with one or more trees and subsequently crashed.
Investigation Findings
Investigators examined the aircraft and found that the wire-reinforced induction air hose was collapsed. However, the hose had sustained impact damage in the area where it was collapsed, preventing investigators from verifying its condition prior to the impact. No other preimpact mechanical malfunctions or failures that could have caused the loss of engine power were identified.
