What was found
ACFT CAME IN FOR A TIRE CHANGE. UPON REMOVAL OF THE NOSE WHEEL ASSY PN 40-77B, IT WAS NOTED THAT ONE WHEEL TIE BOLT WAS MISSING. THIS WHEEL HAS A TOTAL OF 3 TIE BOLTS INSTALLED FROM THE OEM. NO OTHER DAMAGE WAS NOTED DURING A VISUAL INSPECTION OF THE WHEEL. ALL TIE BOLTS AND NUTS WERE REPLACED USING THE PARTS LISTED IN MFG PARTS CATALOG. MFG ISSUED SB1177 ON NOV 14, 2006 THAT ADDRESSES THIS PROBLEM ON PA46-500TP ACFT, WHICH USES THE SAME WHEEL ASSY. SB 1177 REFERS TO CLEVELAND WHEEL SB 7083. THIS UPGRADES THE 40-77B WHEEL TO A 40-77G WITH HIGHER STRENGTH BOLTS AND NUTS.
