## Discrepancy

THE A/C DEPARTED SFA EN ROUTE TO LGA, WHEN THE LANDING GEAR WAS SELECTED UP THE LEFT MLG DID NOT RETRACT.  THE A/C RETURNED TO SFA AND LANDED WITHOUT INCIDENT.  AN EXAMINATION OF THE AFT TIMING VALVE REVEALED A SMALL CRACK IN THE STRIKER ARM, THIS ALLOWED THE LEFT MLG DOOR AFT TIMING VALVE TO GO OUT OF RIG.  THE AIRCRAFT WAS FERRIED WITH THE GEAR DOWN TO A BASE WHERE THE ARM WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.  THE CRACK STARTED IN A HOLE DRILLED FOR SAFTY WIRE.  THE CRACK IS ONLY .25 INCH LONG AND IS DIFFICULT TO SEE.  (M)
