What was found
UPON LANDING IN KGYY THE NOSE WHEEL STEERING SYSTEM DISENGAGED RESULTING IN THE CREW HAVING TO USE EMERGENCY PROCEDURES ( DIFFERENTIAL BRAKING ) TO KEEP ON THE RUN WAY. THE AIRCRAFT BLEW TWO TIRES IN THE PROCESS. THE AIRCRAFT WAS THEN TOWED OFF THE RUNWAY WITH OUT FURTHER INCIDENT. THE AIRCRAFT JUST CAME OUT OF MAINTENANCE AT BOMBARDIER IN ICT FOR THE SAME ISSUE. THEY THOUGHT THEY HAD THE ISSUE RESOLVED. THE AIRCRAFT IS CURRENTLY OUT OF SERVICE IN KGYY NOW AND AWAITING A BOMBARDIER AOG TEAM TO COME WORK IT. WILL UPDATE THIS AS SOON AS I KNOW WHAT THE FIX IS.
