Sunday, September 26, 2004 11:37 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said he was asked by the tower to make a short approach. He was then asked to make his right base turn, such that he had to continue his turn to roll out on final over the runway. The pilot said he leveled the wings and had a hard landing. The pilot said that the right main landing gear collapsed and the airplane slid off the left side of the runway. An examination of the airplane showed the left main landing gear strut was broken and pushed upward through the top of the left wing engine nacelle. The right wing was broken upward at the wing root. Both propellers' blades showed torsional bending and chordwise scratches. Flight control continuity was confirmed. No other anomalies were found.

NTSB Probable Cause Narrative

the pilot's improper in-flight planning/decision to accept a short traffic pattern and the improper flare resulting in a hard landing.
