## Discrepancy

(CAN) IN DESCENT, THE PILOT SELECTED GEAR DOWN. THE GEAR FAILED TO EXTEND AND THE PILOT CYCLED THE GEAR 4 TIMES WITH NO RESULT, ON THE 5 CYCLE, THE GEAR EXTENDED. MAINTENANCE PLACED THE AIRCRAFT ON JACKS AND NOTED THAT WHEN GEAR EXTENSION WAS SELECTED, IT TOOK ABOUT 10 SECONDS BEFORE THE GEAR INITIATED THE COMMAND. THE LANDING GEAR SELECTOR WAS FOUND TO BE CAUSING THE DELAY, THE SELECTOR WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE. (TC NR 20070913007)
