## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

NARRATIVE: N602UA, ENROUTE FROM AMSTERDAM TO IAD DECLARED AN INFLIGHT EMERGENCY DUE TO THE PRESENCE OF HIGH CONTROL WHEEL FORCES EXPERIENCED BY THE FLIGHT CREW AND DIVERTED TO EWR. N602UA LANDED ON RWY 4R AT 1513HR EST WITHOUT INCIDENT. THE HIGH CONTROL WHEEL FORCES (ROLL AXIS) WAS EVIDENT AFTER THE AIRCRAFT'S AUTO PILOT WAS MANUALLY DISCONNECTED DUE TO A FAILURE TO EXECUTE A NAVIGATIONAL COMMAND FROM THE FLIGHT MANAGEMENT COMPUTER (FMC). THE LEFT FMC AND RIGHT FLIGHT CONTROL COMPUTER (FCC) WERE REPLACED TO CORRECT THE FMC MALFUNCTION. HOWEVER, THE HIGH CONTROL WHEEL FORCES REMAINED. THE LEFT LATERAL CENTRAL CONTROL ACTUATOR (LCCA) TORQUE TUBE ASSY, LOCATED IN THE LEFT WHEEL WELL, WAS REPLACED DUE TO ONE OF THE CONNECTING ROD BEARING ATTACH POINT EXHIBITED RUST. ALSO, A COMPLETE LATERAL CONTROL SYSTEM INSPECTION WAS PERFORMED AND FOUND SATISFACTORY. THREE HOURS INTO TEST FLIGHT/FERRY TO SFO, THE FORCES WERE STILL PRESENT. AT SFO, UALA REMOVED THE RIGHT LCCA TORQUE TUBE ASSY AND NOTED A FROZEN BEARING AT ITS LOWER PIVOT POINT. THE BEARING WAS REPLACED AND THE AIRCRAFT WAS TEST FLOWN AT FL410 AND THE HIGH CONTROL WHEEL FORCES WERE NO LONGER PRESENT. UALA AMENDED ITS MAINTENANCE PROGRAM TO REPLACE ALL BEARINGS ASSOCIATED WITH THE LEFT AND RIGHT LCCAS AT FIRST MAINTENANCE OPPORTUNITY AND ROUTINE REPLACEMENT AT 8C (10 YRS) INTERVALS. UALA PLANS TO INSTALL STAINLESS STEEL IN LIEU OF EXISTING ALUMINUM BEARING WHEN AVAILABLE. THIS INCIDENT CLOSED.
