Probable cause

The pilot's improper compensation for wind conditions & his failure to maintain directional control. Factors related to the accident were: the pilot's operation of the aircraft with a known deficiency (worn tire), the adverse wind conditions, and barrels (barricade).

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot stated that during a landing, a gust of wind was encountered which effected directional control of the aircraft. It then departed the runway & struck a barrel barricade before coming to rest. An exam of the wreckage revealed a blown (ruptured) nose gear tire. The tire was worn to the cord area & reportedly, it had been that way prior to the accident.
