Aircraft Accident/Incident Report

Gillette, Wyoming 82716
Monday, December 20, 1982 20:15 MST

NTSB Narrative Summary Released at Completion of Accident

DIRECTIONAL CONTROL WAS LOST IN THE EARLY STAGE OF THE TAKEOFF ROLL. THE ACFT DEPARTED THE RWY 400 FT DOWN THE RWY & TRAVELLED 85 FT OFF THE SIDE OF THE RWY. ONE RWY LIGHT WAS DESTROYED. THE ACFT HAD COME FROM THE FACTORY EQUIPPED WITH AN ANTI-SKID BRAKE SYSTEM. THE SYSTEM WAS REPLACED WITH A STANDARD BRAKING SYSTEM PRIOR TO THE ACFT'S FIRST PASSENGER FLT. DURING THIS PROCESS HYDRAULIC LINES ATTACHED TO THE PARKING BRAKE SHUTTLE VALVE UNDER THE INSTRUMENT PANEL AREA WERE INADVERTENTLY REVERSED, ALLOWING BRAKING ACTION TO TAKE PLACE ON THE OPPOSITE LANDING GEAR OF THE BRAKE PEDAL BEING DEPRESSED. THE FLT CREW WAS UNAWARE OF THIS CONDITION SINCE THEY HAD BEEN USING ASYMMETRICAL THRUST FOR DIRECTIONAL CONTROL UNTIL THIS TAKEOFF.
