## Discrepancy

SPAR TUBE CRACKED AT RT MOUNTING HOLE, CRACK ORIGINATES AT MOUNTING HOLE AND EXTENDS IN BOTH DIRECTIONS COVERING 50 PERCENT OF TUBE CIRCUMFERENCE.  THIS DEFECT WAS FOUND WHEN THE STABILIZER WAS BROUGHT IN FOR REPAIR OF WORN MOUNT BUSHING. THIS CRACK COULD NOT BE SEEN AS IT IS COVERED BY HALF SHELL REINFORCEMENTS.  SUBMITTER SUGGESTS CAUSE AS LACK OF PREVENTIVE MAINTENANCE, NOT FOLLOWING INSPECTION SCHEDULES.  T/R OUT OF BALANCE FOR EXTENDED PERIODS.
