## Discrepancy

PILOT SELECTED GEARDOWN AND NOTHING HAPPENED.  LANDING GEAR WOULD NOT EXTEND.  FLIGHT CREW EXTENDED LANDING GEAR MANUALLY AND LANDED WITHOUT INCIDENT.  MAINTENANCE TECH TROUBLESHOT GEAR SYSTEM AND FOUND THE DYNAMIC BRAKE RELAY WAS INTERMITTENT.  RECOMMENDATION IS FOR MFG TO INVESTIGATE THIS ISSUE WHICH HAS HAPPENED ON SEVERAL OCCASIONS AND COME UP WITH AN IMPROVED RELAY THAT IS MORE RELIABLE.  (K)
