## Discrepancy

(CAN) BOTH LEFT AND RIGHT HAND INBOARD FLAPS WERE FOUND TO HAVE CRACKS IN THEIR SPARS. THE CRACKS, APPROXIMATELY 1 INCH IN LENGTH ARE LOCATED AT THE SLOT IN THE SPAR THAT ALLOWS THE INBOARD FLAP TRACK TO PASS THROUGH. THE CRACKS RADIATE IN BOTH DIRECTIONS AWAY FROM THE TOP CORNERS OF THE SLOT AND RUN PARALLEL TO THE LENGTH OF THE SPAR.
