Aircraft Accident/Incident Report
Broomfield, Colorado 80020
Wednesday, August 14, 2002 10:11 MDT
NTSB Narrative Summary Released at Completion of Accident
The pilot taxied onto runway 29R, with approximately 700 gallons of fire retardant. He started the takeoff roll and at approximately 800 to 900 feet down the runway he heard a "distinct bang." The airplane immediately started an uncommanded turn to the left, and the pilot, using right rudder and right braking action, could not regain control of the aircraft. The airplane departed the runway and impacted the Visual Approach Slope Indictor box, which sheared the right main landing gear off. Subsequently, the right wing and aileron were bent up. Postaccident examination of the airplane by maintenance personnel revealed that the left main tire inner seal had separated from the wheel. No determination was made why this event occurred. A Federal Aviation Administration inspector said he found two black skid marks on the runway; the left one started 10 to 15 feet before the right one.
NTSB Probable Cause Narrative
the airplane's left main landing gear tire separated from its wheel during takeoff roll for an undetermined reason. Contributing factors were the pilot's inability to maintain aircraft control during takeoff roll and the subsequent impact with the Visual Approach Slope Indicator box.
