## Discrepancy

LANDING GEAR WOULD NOT RETRACT IN FLIGHT.  AIRCRAFT WAS PLACED ON JACKS AND THE LANDING GEAR CYCLED IAW MM.  INSPECTION OF THE SYSTEM FOUND THAT THE DYNAMIC RELAY WOULD STICK IN THE DOWN POSITION.  A NEW DYNAMIC RELAY WAS INSTALLED AND THE SYSTEM CHECKED NORMAL.  SUGGEST REPLACING RELAY WITH SOLID STATE BOARD.
