## Discrepancy

WHILE DISASSEMBLYING THE LEFT MAIN LANDING GEAR FOR AN AXLE CHANGE, FOUND ISOLATION PISTON STEM THAT THE DAMPENING SPRING SURROUNDS WAS BROKEN FLUSH AT THE PISTON HOUSING.  SEE CITATION 500 COMPONENT MM, PAGE 32-10-00, FIGURE 1002, SHEET 2, ITEMS 110, 113, 114, 115.  THIS STEM HAS BEEN CRACKED BROKEN FOR QUITE SOME TIME.
