What was found
UPON APPROACH INTO PAKU IT WAS IDENTIFIED BY THE FLIGHT MECHANIC ONBOARD THAT THE NR 2 SPINNER SEEMED OFF OF CENTER AND HAD MORE MOVEMENT DURING ROTATION THAN TYPICAL. AFTER LANDING THE MECH INVESTIGATED FURTHER & FOUND WHAT APPEARED TO BE LOOSE SLEEVE NUT FASTENERS ON THE SPINNER. WHEN THESE FASTENERS WERE TORQUED 4 OF THE 12 PULLED THROUGH THE GROMMETS COMPLETELY DUE TO WEAR IN THE GROMMETS. THE SPINNER WAS THEN REMOVED AND IT WAS FOUND THAT AN ADDITIONAL 2 GROMMETS WERE WORN RESULTING IN AN INABILITY OF THE SLEEVE NUTS TO BE ABLE TO SECURE THE SPINNER PROPERLY. ALSO WHEN THE SPINNER WAS REMOVED IT WAS FOUND THAT THE RUBBER RING IN THE NOSE CONE BULKHEAD OF THE SPINNER WAS NO LONGER BONDED AND FELL OUT. THE RUBBER RING WAS CUT IN SUCH A WAY TO MAKE IT APPEAR THAT IT HAD BEEN IN PLACE FOR ONLY HALF OF THE CIRCUMFERENCE WHICH WOULD ALLOW THE NOSE OF THE SPINNER TO NOT BE PROPERLY SUPPORTED AND THEREFORE ALLOW THE SPINNER MORE MOVEMENT THAN TYPICAL. IT IS BELIEVED THAT THIS MOVEMENT CAUSED ACCELERATED WEAR OF THE GROMMETS SO THAT ONCE IDENTIFIED 6 OF THE 12 FASTENERS WERE NO LONGER ABLE TO SECURE THE SPINNER PROPERLY.
