## Discrepancy

WHEN CHANGING SHOCK CORDS ON THIS AC, NOTICED A DISCOLORATION OF THE INNER STRUT TUBE (LONGER ONE, SUB PN 1180400) AND REMOVED IT FROM THE OUTER TUBE (SHORTER, SUB PN 1180300) ONE OF THE INNER STRUT TUBES WAS CORRODED APPROX 50 PERCENT OF CIRCUMFERENCE.  THE OTHER INNER STRUT HAD MULTIPLE CORROSION HOLES THROUGH ALL THE METAL.  BOTH SHORT TUBES (OUTER) SHOWED OVAL ELONGATION AT THE ENDS INDICATING FLEXING/BENDING OF THE ASSY DURING LANDINGS AND TAKEOFF.
