## Analysis

IMMEDIATELY AFTER TAKEOFF THE PLT NOTED STRONG PRESSURE ON THE RIGHT RUDDER. HE TRIMMED OUT THE RUDDER PRESSURE AND CONTINUED TO FLY IN THE LOCAL AREA. APPROACH FLARE AND TOUCHDOWN WERE NORMAL. WHEN THE NOSE WHEEL CONTACTED THE RUNWAY THE AIRPLANE VEERED SHARPLY TO THE LEFT, TIPPED TO THE RIGHT, AND DRAGGED THE RIGHT WING TIP RESULTING IN SUBSTANTIAL DAMAGE TO THE RIGHT WING. THE BOLT (AN3H3A) THAT HOLDS THE COLLAR (PN1243617-1) TO THE STRUT WAS FOUND BROKEN ALLOWING THE COLLAR TO BECOME LOOSE PREVENTING THE NOSEWHEEL FROM CENTERING WHEN AIRPLANE BECAME AIRBORNE. THE COCKED NOSEWHEEL RESULTED IN THE UNUSUAL RUDDER PRESSURE. EXAM OF THE FRACTURED SURFACE OF THE BOLT SHOWED THAT OXIDATION HAD REMOVED THE FRACTURE PATTERN. THE CAUSE OF THE BOLT FAILURE COULD NOT BE DETERMINED.
