## Discrepancy

WHEN THE THRUST REVERSERS WERE DEPLOYED ON THE AIRCRAFT. A VERY LOUD SQUEALING NOISE CAME FROM THE NOSE LANDING GEAR STEERING CONTROL VALVE. THIS IS THE 4TH REPLACEMENT UNIT INSTALLED ON THE AIRCRAFT. THE 5TH UNIT SERIAL NO. IL0138 RESOLVED THE PROBLEM. AND THE AIRCRAFT WAS RETURNED TO SERVICE.
