What happened
During the landing phase on runway 26, the airplane deviated to the right immediately after touchdown. In an effort to regain altitude and airspeed, the pilot advanced the engine throttle to full power. The right wing then struck a runway sign located to the right of the runway centerline, which resulted in the rupture of the right wing fuel tank.
Following the impact, the pilot reduced the throttle and attempted to land on the grass area adjacent to the intersecting runway 20. The aircraft slid across this intersection, causing the right wing to ignite. The airplane eventually stopped approximately 1000 feet to the right of the centerline of runway 20.
The investigation
The pilot reported that the initial deviation occurred upon touchdown. The sequence of events involved a full throttle application followed by contact with ground infrastructure. The rupture of the right wing tank was confirmed as the source of the subsequent fire.
