## Discrepancy

(CAN) POSSIBLE CRACK IN THE BASE OF THE HOOK.  OTHER STRESS CRAZING ALSO APPARENT IN RADIUS OF BASE.  ALL INDICATIONS MAY OR MAY NOT PENETRATE GALVANIZED COATING.  THE AFT AND FORWARD LINK SUPPORTING THE SPRING HAVE VERY SMALL (CLOSE TOLERANCE) HOLES WITH SHARP EDGES.  THE SPRING IS THEREFORE EASILY SCORED UPON INSTALLATION OR REMOVAL.
