## Narrative

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

N579CP WAS CLIMBING THROUGH 10000 FT MSL, ON A DAY WITH PUBLISHED WEATHER 9000 FT OVERCAST IN THE AREA.  AT ABOUT 10000 FT THERE WAS A SUDDEN DROP IN FUEL FLOW, APPROXIMATELY 15 GPH, AND ALSO A NOTED DROP IN MANIFOLD PRESSURE.  SHORTLY THEREAFTER THE AIRPLANE ROLLED LEFT, WENT NOSE DOWN, AND BEGAN A DIVING LEFT TURN.  THIS AIRPLANE ACHIEVED AN ANGLE OF BANK GREATER THAN 40 DEGREES, NOSE DOWN ATTITUDE GREATER THAN 20 DEGREES, AIRSPEEDS GREATER THAN 15 KIAS OVER THE NEVER EXCEED SPEED (VNE), AND RATES OF DESCENT CLOSE TO 9000 FT PER MINUTE.  AT APPROXIMATELY 3700 FT MSL THE PARACHUTE IS DEPLOYED AND THE AIRPLANE LANDS ON TOP OF AN IRRIGATION SYSTEM IN A CORNFIELD.  THERE WERE NO INJURIES TO THE PILOT OR ANYONE ON THE GROUND.  THE AIRPLANE SUFFERED SUBSTANIAL DAMAGE AS DID THE IRRIGATION SYSTEM.  UPON POST FLIGHT INVESTIGATION IT WAS DISCOVERED THAT THE RIGHT SIDE UPPER DECK AIR REFERENCE LINES ARE DISCONNECTED.  WHEN THAT LINE IS DISCONNECTED THE FUEL PUMP LOSES ITS REFERENCE AND THE PUMP STARTS TO REDUCE FUEL FLOW TO THE ENGINE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
