Analysis

During arrival, the pilot observed that an aircraft was stuck in the mud on runway 28. After a short radio discussion with the pilot of the immobilized aircraft, a decision was made to land on the opposite runway. The pilot reported that just prior to touchdown, the airspeed was slower than normal, and that the touchdown was harder than normal. He stated that as the landing roll began, the left gear sank in the mud and collapsed. There was damage to the left flap, both propellers, right wing spar, and right nacelle. The airport elevation was 5286 ft. there was no record of a NOTAM concerning the runway condition.
