Aircraft Accident/Incident Report
Broomfield, Colorado 80021
Friday, April 24, 1998 14:05 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot-owner said that after landing, he brought the condition levers from ground idle to reverse. The airplane veered to the right, as if 'one engine was developing more power than the other.' The instructor pilot took control and attempted to straighten the airplane but it departed the runway and struck a concrete culvert. The left landing gear collapsed, and the tip from one of the left propeller blades penetrated the pressure vessel. The right propeller and right and nose landing gears also sustained damage. During repairs, no abnormalities were found with either the propeller, pitch, or Bendix controllers.
NTSB Probable Cause Narrative
Failure of the flight instructor to maintain adequate supervision, and failure of the pilot receiving instruction to maintain directional control that was lost for reasons undetermined. A factor was the concrete culvert.
