## Discrepancy

(CAN) CRACKS FROM RIVIT HOLE IN 0.125 INCH STAMPED ATTACHMENT FLANGE COMPLETELY ACROSS FLANGE SEPARATING IT INTO TWO PIECES. (NOTE) THERE IS NO DANGER OF STABILIZER SEPARATION FROM THE AIRCRAFT AS THE FLANGE ISSTILL RIVITED TO THE INBOARD RIB IN 5 OTHER PLACES, THE STABILIZER IS CLAMPED TO THE SPAR IN 4 PLAC ES AND THERE IS A STOP ASSEMBLY TO PREVENT SEPARATION AS WELL. THIS PROBLEM HAS BEEN WITH US A LONG TIME BUT WHAT BRINGS THIS ONE TO LIGHT IS WE HAVE FOUND SIX (6) CRACKS ON 5 AIRCRAFT IN TWO MONTHS. RECOMMEND CREWS BE MORE VIGILENT ON INSPECTIONS SO TO DETECT CRACKS BEFORE THEY HAVE A CHANCE TO GROW.
