1990 Starship Gemini T-30

DURING EXTREME BRAKING APPLICATION THE FRONT AXLE ROLLS FORWARD, PUSHING THE STEERING ARM FORWARD, AND NON-UNIFORM BRAKING EFFORT, CAUSED BY VARIOUS BRAKE COMPONENT CONDITIONS, RESULTS IN THE VEHICLE PULLING TO THE RIGHT.

RiskUNEXPECTED PULL TO THE RIGHT DURING BRAKE APPLICATIONCOULD RESULT IN LOSS OF STEERING CONTROL AND AN ACCIDENT.

FixAXLE ROLL WILL BE CORRECTED BY STIFFENING THE UPPER TORQUE ARM TO REDUCE THE ALLOWANCE FOR AXLE ROLL AND RELOCATING THE UPPER TORQUE ARM TO ELIMINATE THE INTERFERENCE WITH THE STEERING ARM. THE NON-UNIFORM BRAKING EFFORT WILL BE CORRECTED BY REPAIRING THE BRAKES IN ACCORDANCE WITH ROCKWELL BRAKE STANDARDS.

REGULAR NUTS, INSTEAD OF LOCKING NUTS, WERE USED TO SECURE AN EXTENSION ARM FROM THE FORWARD SIDE OF THE WINDSHIELD WIPER MOTOR TO THE WIPER ARM. THE NON-LOCKING NUT CAN LOOSEN AND ALLOW THE EXTENSION ARM TO "SLIP" OFF THE TAPERED SHAFT CAUSING THE WIPERS TO CEASE TO FUNCTION.

RiskNON-FUNCTIONING WIPERS RESULTS IN REDUCED VISIBILITY FORTHE DRIVER IN INCLEMENT WEATHER CONDITIONS AND INCREASES THE RISK OF OCCURRENCEOF AN ACCIDENT.

FixREPLACE THE REGULAR NUTS WITH A LOCKING NUT.

THE ROLL PIN USED TO ATTACH THE U-JOINT TO THE STEERING SHAFT CAN "BACK OUT" OF ITS POSITION AND SHEAR.

RiskSHEARING OF THE ROLL PIN CAUSES THE U-JOINT/STEERINGDRIVESHAFT ATTACHMENT TO FAIL AND DROP BELOW ITS NORMAL POSITION, RESULTINGIN LOSS OF STEERING CONTROL.

FixA BOLT AND NUT ARRANGEMENT WILL BE ADDED FOR PROTECTION AGAINST THE PIN FAILURE.
