## Discrepancy

(CAN) ON INSPECTION OF THE HORIZONTAL STABILIZER THE UPPER SKIN WAS FOUND TO BE OIL CANNING.  UPON FURTHER INSPECTION IT WAS FOUND THAT 6 RIBS WERE CRACKED INTERNALLY (PN 115-620010-325, 115-620010-210, 115-620010-355, 115-620010-255, 115-620010-215, 115-620010-209).  WE BELIEVE THIS DAMAGE WAS FROM PEOPLE WALKING ON THE STABILIZER.
