What was found
(CAN) SERVICING THE NOSE OLEO, THE ENGINEER NOTICED THAT THE FORK WAS LOOSE ON THE STRUT. REMOVAL OF THE STRUT REVEALED THAT IT WAS ASSEMBLED INCORRECTLY. THE WASHER P/N 71-309-9 WAS MISSING AND THAT EXTRA PEEL ABLE SHIMS HAD BEEN ADDED. THE SHIMS ARE A SMALLER DIAMETER THAN THE WASHER AND LEFT A SPACE BETWEEN THEM AND THE STRUT. OVERTIME THE SHIMS DEFORMED AND MOVED INTO THE SPACE ALLOWING THE FORK TO BECOME LOOSE.
