## Discrepancy

(CAN) ON FINAL, LANDING GEAR WAS SELECTED DOWN BUT NOTHING HAPPENED -  GEAR WOULD NOT EXTEND.  GEAR HANDLE WAS CYCLED UP & DOWN WITH NO SUCCESS.  HAND PUMP WAS USED TO SUCCESSFULLY EXTEND THE GEAR. LANDING WAS UNEVENTFUL. MX CREW FOUND THE LT ENG HYD FILTER BOWL CRACKED. THE BOWL WAS REPLACED, THE SYS WAS SERVICED AND THE ACFT WAS RETURNED TO SERVICE.
