## Discrepancy

(CAN) MAIN ROTOR BLADE FOUND CRACKED ON THE TOP SURFACE 90 INCHES FROM THE TIP. ABOUT 70 HOURS BEFORE, A CRACK ON THE BLADE PAINT WAS FOUND, AT THAT TIME NO CRACK WAS FOUND IN THE BLADE SKIN.  IAW ASB204-49-96 PT I AND II, THE BLADE WAS INSPECTED DAILY (PART I) AND EACH 25 HOURS (PART II).  8 FLIGHT HOURS BEFORE THE BLADE WAS FOUND SERVICEABLE WITH NO APPARENT CHANGE. THE PILOT REPORTED, FLEW IN TURBULENT CONDITIONS THAT DAY.  IN THE DAILY INSPECTION THE HAIRLINE CRACK ON THE PAINT WAS EXTENDED ALMOST ALL ACROSS THE BLADE.
