## Discrepancy

DURING THE PILOTS PRE FLIGHT, FOUND THAT THE TRIMMING SURFACE ON THE YELLOW BLADE WAS MISSING. UPON INSPECTION FOUND THE TWO RIVET HOLES, WHERE THE RIVETS HELP HOLD THE TRIMMING SURFACE TO THE BLADE, WAS IN ALMOST PERFECT CONDITION. SENT MAIN ROTOR BLADE TO AMERICAN EUROCOPTER FOR REPIAR.
