NTSB Narrative Summary Released at Completion of Accident

THIS ACFT RAN OFF THE DEPARTURE END OF THE 4001' RUNWAY FOLLOWING A NORMAL APPROACH, TOUCHDOWN AND INITIAL BRAKING. AFTER ABOUT 1000' OF NORM BRAKING, THE ACFT BEGAN A DRIFT TO THE RIGHT WHICH WAS PARTIALLY OVERCOME BY FULL LEFT RUDDER AND ASYMMETRICAL BRAKES. AFTER DEPARTING THE RUNWAY THE ACFT ENCOUNTERED DOWN SLOPING TERRAIN WHICH CAUSED THE NOSE GEAR TO COLLAPSE AND BUCKLED THE RIGHT WING. INVESTIGATION REVEALED THAT THE BRAKE LINES ON THE LEFT MLG WERE REVERSED WHICH CAUSED ERRANT COMMAND SIGNALS TO BE TRANSMITTED TO THE ANTI-SKID CONTROL UNIT DURING HEAVY BRAKE APPLICATION, NEGATING THE ANTI-SKID FUNCTION. THE LINES HAD BEEN MIS-INSTALLED DURING THE PREVIOUS BRAKE OVERHAUL. IT WAS NOTED THAT THE MAINTENANCE MANUAL DOES NOT ADDRESS THE CRITICALITY OF PROPER HOSE INSTALLATION AND THAT EITHER HOSE MAY BE INSTALLED IN THE INBD OR OTBD BRAKE HOUSING PORTS. ACFT WAS NOT EQUIPPED WITH REVERSERS.
