Cessna 210H accident near Melbourne, Arkansas, August 9, 2021

The NTSB's narrative final · quoted from the NTSB record

The pilot was conducting a personal flight to his home airport. A witness at the departure airport reported observing the pilot conduct a preflight examination of the airplane and then taxi the airplane to the runway for takeoff. The witness stated that the airplane seemed to have an extended takeoff roll and that the airplane lifted off near the departure end of the runway. Witnesses who were located beyond the departure end of the runway reported that the airplane was flying low and seemed to be turning just before it crashed. The airplane impacted trees and terrain. A postcrash fire ensued and destroyed the airplane. Postaccident examination of the airframe and engine revealed no preimpact anomalies that would have precluded normal operations. The flap actuator was found in the fully extended position (30°). The elevator trim actuator was measured at a 2-inch extension, which was consistent with a 20° nose-down position. With the flaps fully extended, the airplane’s ability to climb and maneuver was significantly degraded. As a result, the pilot was unable to maintain airplane control while making a turn at a low altitude after liftoff. Postmortem toxicology testing showed that the pilot’s hemoglobin A1C level was 7.2%, which indicated the pilot’s diabetes was uncontrolled (but not severely) during the months before the accident. His elevated glucose (sugar) level placed him at risk for fatigue, dehydration, and blurred vision. The investigation could not determine whether the pilot’s uncontrolled diabetes impaired his ability to properly monitor the airplane’s configuration and safely perform the takeoff and climb.
