## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) ON 08/07/99, AT 1420 PDT, A MOONEY M20K, N321RM, REGISTERED TO RONALD LOUIS DONA DEPARTED MATHER FIELD (MHR) ENROUTE TO CAMERON PARK (O61). AFTER THE PILOT INITIATED LANDING GEAR EXTENSION, HE NOTICED THE LANDING GEAR WAS NOT FULLY EXTENDED.  ANOTHER PILOT ON THE FIELD AT O61, BECAME AIRBORNE IN HIS AIRCRAFT AND FOUND THAT THE LEFT MAIN LANDING GEAR WAS NOT EXTENDED.  THE AIRCRAFT RETURNED TO MHR, DECLARED AN EMERGENCY AND LANDED WITH THE LEFT MAIN LANDING GEAR UP.  THE AIRCRAFT SUSTAINED MINIMAL DAMAGE AND THE PILOT WAS NOT INJURED.  INVESTIGATION REVEALED THE LOWER, INBOARD LANDING GEAR DOOR ATTACHMENT SCREWS LOOSENED.  THIS ALLOWED THE INBOARD DOOR TO OVERLAP THE OUTBOARD LANDING GEAR DOOR, WHICH PREVENTED THE LANDING GEAR FROM EXTENDING.  PRIVACY DATA OMITTED ^PRIVACY DATA OMITTED^
