## Discrepancy

(CAN) DURING INSP, IT WAS FOUND THAT AT THE VERY L/E AT WS 121.966, LT WING RIBS AS WELL AS RT WING RIBS WERE CRACKED.   THE CRACKING APPEARED TO BE FROM FATIGUE, AND NOT FROM A TOOLING MARK OR OTHER INDUCED CAUSES.  THE REASON FOR FILING THIS SDR, IS THAT WE FOUND IT ODD THAT BOTH WINGS HAD THE SAME CRACKING, ON THE SAME PARTS. ALL DAMAGED PARTS WERE REPLACED WITH NEW.
