What happened
The pilot reported losing directional control of the aircraft shortly after touchdown. He described the wind conditions as "squirrely" at the moment of contact with the runway. Later, during a telephone interview, the pilot admitted to being complacent at an inappropriate time and acknowledged that he should have maintained positive control throughout the entire operation. The aircraft sustained damage to the right wing, the right landing gear, and the propeller.
The investigation
The investigation focused on the pilot's account of the event. No mechanical failures were identified as the primary cause. The damage was consistent with a loss of directional control during the landing phase.
Findings
The primary factor contributing to the accident was the pilot's failure to maintain positive control due to windshear. The pilot acknowledged his own complacency as a contributing factor. The windshear caused the aircraft to become difficult to control upon touchdown.
