What happened
The aircraft was initially observed executing a climbing right turn. During this maneuver, the airplane entered a spin to the right. The spinning aircraft subsequently impacted the ground in a nose-low attitude, with the nose and right wing striking the terrain first.
The investigation
A thorough examination of the airframe and flight control systems was conducted following the accident. Investigators found no evidence of preimpact failure or malfunction within these systems. Additionally, the engine assembly was inspected and showed no signs of mechanical failure or malfunction prior to the crash.
Findings
The primary finding limiting further diagnostic capability was related to the ignition system. The magnetos sustained damage during the impact, which precluded any functional testing of these components. No other mechanical causes were identified in the available evidence.
