Incident Overview
A pilot reported that during aerial application operations, he was using a dirt road for takeoff. The aircraft was loaded with 40 gallons of fuel and 140 gallons of chemical. The density altitude was estimated to be 8,100 feet.
Sequence of Events
The takeoff was made to the east with a quartering tailwind of about 15 knots. The aircraft lifted off to approximately 15 feet above ground level but then settled back onto the road. The left wheel remained on the road while the right wheel went into the right ditch. Subsequently, the right wing struck fence posts, causing the aircraft to turn to the right and collapsing the left main landing gear.
Damage
As a result of the incident, the left main landing gear collapsed. The right wing also sustained damage from contact with the fence posts.
