What happened
The incident occurred while the aircraft was operating in cruise flight conditions. At some point during this phase of the operation, the engine experienced a sudden failure. In response to the loss of power, the pilot initiated a forced landing procedure and directed the aircraft toward an open field for touchdown.
Upon impact with the ground, the structural integrity of the landing gear was compromised. Both the nose gear and the main landing gear collapsed under the stress of the landing. This collapse resulted in substantial damage to the airframe and associated components.
The investigation
Following the accident, investigators examined the aircraft to determine the root cause of the engine failure. A specific point of interest was the No. 2 cylinder connecting rod, which was found to be failed.
The examination focused on determining why this component had failed. However, the condition of the connecting rod was such that the analysis could not yield a definitive conclusion regarding the initial cause of the failure. The extent of the damage sustained during the accident sequence was excessive, obscuring any potential pre-impact mechanical defects or wear patterns.
Findings
The primary finding relates to the inability to determine the cause of the connecting rod failure due to post-accident damage. The engine failure itself led directly to the forced landing and subsequent gear collapse. No other contributing factors were identified in the provided narrative.
