## Discrepancy

(CAN) DURING APPROACH THE CREW NOTICED THAT THE LANDING GEAR WAS LOUDER THAN USUAL ANDSLOWER TO EXTEND. MAINTENANCE FOUND THE POWER PACK SELECTOR VALVE TO BE INTERMI TTENT AND THE POWER PACK TO BE NOISY. WITH THE AIRCRAFT ON JACKS THERE WERE TIMES WHEN THE GEAR WOULD FAIL TO EXTEND WHEN SELECTED AND HAD TO BE MANUALLY EXTENDED. POWER PACK ASSY INCLUDING THE SELECTOR VALVE WAS REPLACED AND THE LANDING GEAR TESTED SERVICEABLE. AIRCRAFT WAS PLACED BACK INTO SERVICE ON MAY 13TH.
