## Narrative

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

(-23) THE ENGINE MOUNT IS THE STRUCTURE TO WHICH THE NOSE GEAR STRUT ATTACHES. THE NOSE GEAR STRUT HAS AN INTERNAL SHIMMY DAMPENING SYSTEM. DURING LANDING, THE AIRCRAFT EXPERIENCED A SEVERE NOSE WHEEL SHIMMY. THE SHIMMY OCCURRED AT ABOUT 45 KNOTS AND CONTINUED UNTIL THE AIRCRAFT DECELERATED THROUGH 20 KNOTS. THE NOSE GEAR STRUT WAS INSPECTED AND FLUID WAS FOUND LEAKING FROM A LOOSE SCREW. THE SCREW WAS TIGHTENED AND THE STRUT WAS SERVICED WITH MIL-H-5606 AND NITROGEN. ON THE NEXT FLIGHT, A NOSE WHEEL SHIMMY WAS AGAIN ENCOUNTERED DURING LANDING. A POST FLIGHT INSPECTION REVEALED THE ENGINE MOUNT/NOSE STRUT ATTACHMENT STRUCTURE WAS BROKEN IN SIX PLACES. (-23 AMENDMENT) ON 06/01/05, THE AIRCRAFT WAS OPERATED AFTER REPAIR. DURING LANDING A SEVERE SHIMMY WAS ENCOUNTERED. POST FLIGHT INSPECTION REVEALED THE NOSE GEAR STRUT SHAFT WAS TOO HOT TO TOUCH. ADDITIONALLY, THE FORK OIL IN THE NOSE GEAR STRUT HAS CHANGED FROM AMBER IN COLOR TO BLACK AND THE STRUT WAS LEAKING FLUID. AN OPERATION CHECK OF THE SHIMMY DAMPER REVEALED THE SYSTEM WAS NOT FUNCTIONING PROPERLY ALLOWING THE NOSE GEAR TO CASTER WITHOUT RESISTANCE.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
