No mechanical failures were reported; crosswinds exceeded the aircraft's demonstrated capability.
Accident Sequence
According to the pilot's report, during the takeoff roll a wind gust caused the left wing to rise and the airplane to veer to the right. The pilot immediately applied left aileron and rudder inputs, but the controls were ineffective. The airplane departed the runway, struck a tree and a fence, and subsequently came to rest with its nose in a drained swimming pool.
