What happened
While en route to his destination, the pilot encountered a line of thunderstorms and elected to divert to Ackerman, MS. Upon arrival, the pilot circled the airport to assess local wind conditions. Based on the appearance of the windsock, the pilot believed the winds were calm.
During the approach to runway 5, the pilot identified a downwind current. At this stage of the landing, the aircraft was in a nose-high attitude with the landing gear and full flaps extended. The pilot reported that the aircraft was behind the power curve, which rendered a go-around impossible.
The aircraft touched down beyond the midfield point of the runway. Despite the application of maximum braking, the pilot could not stop the aircraft within the remaining runway length. The aircraft continued off the departure end of the runway and struck potholes in the overrun area, resulting in aircraft damage.
The investigation
Following the accident, an examination of the airport's windsock was conducted. The inspection revealed that the windsock was in a state of disrepair, as most of its fabric was missing.
