## Discrepancy

WITH ONLY 240.4 HRS TT ON ACFT, CRACKS WERE DISCOVERED ON THE RT T/E OF THE WING.  THE UPPER SKIN WAS CRACKED IN 2 PLACES AT THE OTBD END.  THE LOWER SKIN WAS CRACKED AT THE OTBD END.  AFTER THE SKINS WERE REMOVED A CRACK WAS DISCOVERED IN THE OTBD RIB AND THE ANGLE, THAT ATTACHES THE RIB TO THE SPAR.  A CRACK WAS ALSO DISCOVERED ON THE ANGLE JUST INBD OF THE PREVIOUSLY STATED CRACKED RIB.
