Aircraft Accident/Incident Report

Erie, Colorado 80526
Sunday, August 29, 2004 9:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that his approach speed was too high and he "ballooned." The airplane began to porpoise and impacted the nose gear. The pilot added power and aborted the landing. At the time of the landing, the pilot was not aware that a propeller strike had occurred. The flight returned to BJC and a postflight inspection revealed that the firewall was wrinkled and the propeller was damaged.

NTSB Probable Cause Narrative

the pilot's failure to maintain aircraft control resulting in a hard landing. Factors contributing to the accident were the pilot induced oscillation and the high approach airspeed.
