## Discrepancy

FLYING AT LOW ALTITUDE. WHEN FLAP WAS UP, A STRANGE SOUND WAS HEARD, AND FOUND THE LEFT FLAP CANNOT BE PROPERLY OPERATED. THE PLANE LANDED SAFELY AND NO ONE WAS INJURED. THE INSPECTION FOUND THAT THE FLAP TRACK WAS JAMMED, AND FOUND THAT THE ROOT OF THE INNER RIB (PN:2425001-3) OF THE LEFT FLAP HAD A CRACK, AND THE RIVET AT THE ROOT OF THE RIBS (PN:2425001-3) WAS BROKEN, AND THE LEFT AND RIGHT SKIN CONNECTION BRACKET (PN:0523231-24) WERE BROKEN.
