When the pilot initiated full flaps for landing approaching the threshold of runway 34L at Seattle, the aircraft's airspeed began to decay rapidly and a high sink rate developed as the aircraft entered into a stall/mush condition. The aircraft then landed hard, overloading the nose and left-main landing gear which collapsed. A post-impact fuel system leak during the ground slide led to a post-crash fire.

Probable Cause:

PROBABLE CAUSE: "A stall/mush condition resulting from an aft center of gravity which was inaccurately provided to the pilot-in-command by contractual cargo-loading personnel. Additional causes were overloading of the aircraft's landing gear and fuel leakage resulting in a post-crash fire. Factors contributing to the accident were the pilot's improper lowering of flaps in an aft CG situation and the inadequate company procedures for cargo loading."
