CEN21FA025 · Beech V35 A

The pilot and flight instructor had just completed a one-hour uneventful local flight to test the recently-repaired autopilot. The pilot landed the airplane, dropped off the instructor at the terminal, and then taxied away. Minutes later the airplane departed to the north, reached about 200 ft above the ground, and entered a left turn. The airplane subsequently descended into trees and terrain and a postimpact fire consumed most of the airplane. There were no witnesses to the accident, and about 4 hours after the accident smoke from the wreckage was reported by another pilot. Examination of the wreckage did not reveal any preimpact mechanical malfunctions or anomalies that would have precluded normal operation; the accident site was consistent with a steep, nose-low descent with the engine producing power. The medical investigation in this case revealed that the pilot had a history of significant coronary artery disease with stents and had used a sedating medication (cetirizine) at some time before the flight; however, whether the pilot’s heart condition or use of sedating medication contributed to the accident could not be determined based on the available information. The evidence at the accident site and the lack of mechanical anomalies are consistent with a loss of control during takeoff; however, the reason for the loss of control could not be determined.
