Diversion and Landing
A pilot diverted to a nearby airport because of deteriorating weather along the planned route. While overflying the runway to assess wind direction, the pilot observed an airplane parked on the approach end of runway 19. Consequently, the pilot decided to land on runway 01 with a 6-knot quartering right tailwind.
Touchdown and Loss of Control
After touching down on the wet runway, the pilot applied heavy braking. The pilot believed that one of the landing gear wheels may have locked up or skidded on a wet area while the other wheel did not. The airplane subsequently veered off from the runway centerline. The pilot reduced braking in an attempt to regain directional control, but the airplane overran the runway, and the left wing impacted a metal pole.
Damage and Mechanical Status
The airplane's left-wing forward spar was substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
