What was found
RIGHT SLIDING WINDOW (PILOT'S DOOR) DEPARTED AIRCRAFT. PILOT REPORTED THE AIR TURBULENCE REMOVED THE WINDOW FROM ITS TRACKS. AIRCRAFT WAS GROUNDED UNTIL A REPLACEMENT WINDOW WAS AVAILABLE AND A HIDDEN DAMAGE INSPECTION WAS PERFORMED. MINOR ALTERATIONS TO THE DESIGN MAY BE INCORPORATED TO PREVENT THE HANDLE FROM HITTING THE SOLID WINDOW, WHICH MAY HAVE SET UP A CRACK IN THE HANDLE ASSY WHICH IS ALSO USED AS THE SLIDE STOP.
