Primary finding
Probable cause
The pilot's failure to maintain aircraft control while on final approach with shifting wind conditions.
Investigator assessment
Analysis narrative
The pilot stated that when on short final the airplane encountered a sudden downdraft or slight wind shear, which caused the left wing to dip and contact the ground. Following the wing tip dip the airplane yawed left and the main landing gear touched down and collapsed. The resulting damage to the airplane was the right wing tip, left wing, left wing lift strut, and right main landing gear. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
