## Narrative

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

AIRCRAFT WAS ENROUTE FROM CHANDLER, ARIZONA TO NORTH LAS VEGAS, NEVADA ON A DAYTIME VISUAL FLIGHT.

UPON CHECKING IN WITH ATC FOR AN APPROACH INTO THE NORTH LAS VEGAS AIRPORT, PILOT REQUESTED "PRIORITY HANDLING" DUE TO "A CHIP LIGHT".  A SHORT TIME LATER THE PILOT DECLARED AN EMERGENCY STATING THAT HE HAD ?LOST A CYLINDER? AND ?LOST THE ENGINE?.  THE PILOT DECLARED THAT HE WOULD BE DIVERTING TO THE BOULDER CITY, NEVADA AIRPORT FOR AN EMERGENCY LANDING.

AFTER BEING ACKNOWLEDGED BY ATC, THE PILOT STATED THAT EVERYTHING APPEARED TO BE STABLIZED, THAT THEY HAD THE LANDING GEAR DOWN AND WERE DESCENDING FOR A LANDING AT BOULDER CITY.  THE PILOT STATED HE WOULD BE CHANGING RADIO FREQUENCY FOR THE BOULDER CITY AIRPORT.

THE WRECKAGE OF THE AIRCRAFT WAS LOCATED APPROXIMATELY 1.2 MILES WEST OF THE BOULDER CITY AIRPORT.  BOTH OCCUPANTS OF THE AIRCRAFT HAD SUSTAINED FATAL INJURIES.

ATC RADAR DATA SHOWED THAT THE AIRCAFT WAS APPROXIMATELY EIGHTEEN HUNDRED (1,800) FEET ABOVE GROUND LEVEL AT THE LAST POSITION CAPTURED BY RADAR.

INVESTIGATION AT THE SCENE REVEALED INDICATIONS AND FACTUAL DATA CONSISTANT WITH THE AIRCRAFT HAVING ENTERED A STALL / SPIN.

FURTHER INVESTIGATION REVEALED THAT ONE OF THE AIRCRAFT ENGINE CYLINDERS MAY HAVE BECOME DISCONNECTED FROM THE ENGINE PRIOR TO THE CRASH AND THAT THE ENGINE HAD POSSIBLY SEIZED.
