## Discrepancy

(CAN) PILOTS WERE NOT ABLE TO EXTEND LANDING GEAR. GEAR WAS PUMPED DOWN (EMERGENCY EXTENSION). AIRCRAFT LANDED WITHOUT INCIDENT. CHECK VALVE WAS FOUND CRACKED, ALLOWING FLUID TO EXCAPE SYSTEM. NO PHYSICAL DAMAGE THAT COULD CAUSE CRACK WAS EVIDENT. PART REPLACED. SYSTEM CHECKED AND SERVICED AND AIRCRAFT RETURNED TO SERVICE.
