## Discrepancy

UPPER RUDDER RIB WAS FOUND BROKEN AT THE OPENING FOR UPPER HINGE BOLT INSTALLATION ACCESS.  THIS TYPE OF DAMAGE IS A REOCCURRING PROBLEM DUE TO A LACK OF PROPER GUST LOCKS FOR THE RUDDERS, WIND SLAPPING OF THE RUDDER WITH THE ARM OF THE BALANCE WEIGHT CAUSING CRACKS IN THE RIB WEAK POINT EVEN WITH THE ADDED DOUBLER.  PROPER SECURING THE RUDDER WHEN OUTSIDE, MAY PREVENT FURTHER DAMAGE.
