## Discrepancy

DURING ROUTINE INSPECTION, LOOKED INTO NACA SCOOPS AND SAW THE UPPER VANE PN 651207211 AND LOWER VANE PN 651207212 MISSING 1 INCH X 1 INCH AND A 1 INCH X 2 INCH PART OF VANE.  BOTH CRACKS STARTED AT (V CUT).  PARTS WERE FOUND DOWN STREAM PAST THE FRESH AIR CHECK VALVE AND THE OVERHEAD BLOWER WEDGED IN DUCT WORK.  REPLACED BROKEN VANES WITH NEW AND SECURED IN PLACE WITH EA9309 IAW MM.  BEFORE REINSTALLATION, WE DRILLED A RELIEF HOLE AT THE BOTTOM OF (V).  AS WITH OTHER SCR`S, CONCERNED WITH THE BROKEN PARTS BECOMING WEDGED IN THE FRESH AIR CHECK VALVE (WHICH WOULD NOT ALLOW CABIN TO HOLD PRESSURE) AND OR THE OVERHEAD BLOWER FAN.
