What was found
(CAN) DURING INSP, IT WAS FOUND THAT AT THE LT WING L/E, AT WS 121.966, RIB PN:50-980002-825 WAS CRACKED. THE CRACKING APPEARED TO BE FROM FATIGUE AND NOT FROM A TOOLING MARK OR OTHER INDUCED CAUSES. THE REASON FOR THIS SDR IS THAT THIS IS THE THIRD AIRCRAFT IN OUR FLEET TO HAVE THIS TYPE OF DAMAGE FOUND AT THIS EXACT LOCATION. THE DAMAGED PART WAS REPLACED WITH NEW.
