A pilot overloaded the aircraft with 900 pounds of wheat seed, resulting in a failure to climb after takeoff and a collision with an irrigation sprinkler and the ground.

What happened

The pilot loaded the airplane with 900 pounds of wheat seed for transport. During the takeoff phase, the aircraft required the entire length of the available pasture runway to achieve lift and become airborne. Once in the air, the airplane was unable to climb effectively due to the excessive weight. The pilot attempted to jettison the load but determined that it could not be discarded quickly enough to avoid a collision with an irrigation sprinkler and the ground.

Probable cause

The pilot's decision to overload the aircraft with 900 pounds of wheat seed, which prevented adequate climb performance after takeoff.
