Investigator assessment
Analysis narrative
The pilot reported he was conducting an instrument approach in dark night conditions, and during the approach he thought the airplane was too high. The pilot performed a left turn circling procedure to lose altitude. During the turn, the pilot loss sight of the runway and the airplane impacted terrain. The airplane sustained substantial damage to the fuselage and both wings. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.
