Narrative:
An Antonov 2, N122AN, was substantially damaged following a loss of engine power and forced landing near Loxley, Alabama. The certificated commercial pilot and two passengers were not injured. The flight originated from Fort Walton Beach, Florida (DTS), about 11:18, and was destined for De Ridder, LA (DRI).
The pilot reported that, while in cruise flight at 1,000 feet above ground level, the engine began to run rough and lose power. He then heard a loud, "metal-on-metal" sound, the engine vibrated violently, and it subsequently quit completely. The airplane was force landed in a farm field and nosed over in the soft terrain causing structural damage to the wings.
Examination of the engine oil screens revealed an 'extreme' amount of metal particles in the oil supply.

PROBABLE CAUSE: "A loss of engine power due to internal failure."
