The private pilot and three passengers had landed at a remote airstrip earlier in the morning to visit the pilot’s ranch. The published guidance for the airstrip noted that the runway was 2,500 ft long and 75 ft wide. After being on the ground about 2 hours 30 minutes, the pilot indicated to ranch personnel that he wanted to depart before the wind increased. Shortly thereafter, the airplane departed with an estimated 4- to 5-kt tailwind. During the initial climb, the nose landing gear and left tire impacted a tree (which was about 50 ft tall) located about 100 ft from the fence that made the perimeter of the runway. The left tire then likely impacted the left horizontal stabilizer and elevator, rendering the airplane uncontrollable. The airplane then descended into a creek and came to rest inverted; a postimpact fire ensued. There was no evidence of any mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
The performance data were calculated using the estimated airplane and environmental conditions at the time of the accident. The distance required to clear a 50-ft obstacle for a takeoff with a 5-kt tailwind from a dry grass runway similar to the accident runway was about 2,675 ft. The actual distance from the area where the pilot began the takeoff roll to the first impacted tree was about 2,625 ft, which indicates that the airplane did not have the sufficient performance capability to climb over the tree.
The pilot frequently flew into the airstrip and was familiar with the terrain and departure procedures, and GPS data revealed that the pilot departed from the airstrip on nine prior occasions in the past year. Comparison of these flights to the accident flight revealed that the pilot’s flightpath was normally to the right of the accident flightpath. The pilot likely would have not been able to see the tree due to the airplane’s nose-high pitch configuration during the takeoff.
Probable Cause: The pilot's attempt to depart in conditions that resulted in the airplane having insufficient performance capability, which resulted in a collision with a tree.
