## Discrepancy

ON FINAL APPROACH TO LAND, THE ENGINE QUIT.  AIRCRAFT GLIDED TO A LANDING AND ROLLED CLEAR OF THE ACTIVE RUNWAY.  ENGINE WOULD NOT RESTART, PUSHED AIRCRAFT TO PARKING SPOT.  WHEN AME EXAMINED THE ENGINE FOUND THE IDLE MIXTURE CONTROL SCREW HAD WORKED LOOSE AND DEPARTED THE AIRCRAFT IN FLIGHT.  REPLACED MIXTURE SCREW AND ENGINE RAN FINE.  ALL MIXTURE SCREWS WILL BE LOCKWIRED FOR SAFETY FROM NOW ON.
