2009 TRANS TECH RONDAK DW5138FRL

EQUIPMENT ADAPTIVE/MOBILITY

TRANS TECH HAS NOTIFIED NHTSA ABOUT A DEFECT IN CERTAIN 2009 TRANS TECH SCHOOL BUSES MANUFACTURED BETWEEN MAY 1 AND OCTOBER 31, 2009, EQUIPPED WITH CERTAIN RICON S SERIES AND K SERIES L-MODEL WHEELCHAIR LIFTS. DUE TO A PROBLEM IN THE SOFTWARE THAT CONTROLS THE LIFTS UP FUNCTION, IF THE SWITCH IS RELEASED BEFORE THE FLOOR LEVEL LIMIT SWITCH IS ACTIVATED, THE LIFT MAY CONTINUE ITS UPWARD TRAVEL FOR APPROXIMATELY 1 SECOND BEFORE STOPPING. THE CONTINUED UPWARD TRAVEL MAY OVERRUN THE FLOOR LEVEL CUT OFF POINT.

Risk: WHEN THE PLATFORM OVERRUNS THE VEHICLE FLOOR LEVEL AND STOPS AT AN ANGLE FROM 15-20 DEGREES, IT IS POSSIBLE FOR A PERSON IN A WHEELCHAIR TO TIP OVER AND FOR SOMEONE STANDING ON THE PLATFORM TO FALL, POSSIBLY RESULTING IN INJURIES.
