## Probable cause

THE PILOT FAILED TO PROVIDE THE AIRCRAFT WITH A FUEL SUPPLY ADEQUATE TO COMPLETE THE PROPOSED FLIGHT AND THE PILOTS FAILURE TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRCRAFT DURING THE LANDING ROLL ON THE ACTIVE RUNWAY.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(partial) - nonmechanical, cruise - normal
  - fuel supply - inadequate, pilot in command
  - preflight planning/preparation - inadequate, pilot in command (contributing factor)
  - wind information - not obtained, pilot in command (contributing factor)
  - in-flight planning/decision - poor, pilot in command (cause)
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - anxiety/apprehension, pilot in command (contributing factor)

## Analysis

THE PIC BOARDED 5 PSNGR'S AND A FUEL LOAD OF 120 GALLONS FOR A 375 NM TRIP TO KANSAS. THE PIC STATED HE ENCOUNTERED STRONG WINDS ALOFT THAT REDUCED HIS FUEL SUPPLY TO A CRITICAL STATE. WHILE AT CRUISE FLT ABOUT 51 NM SHORT OF HIS DESTINATION THE RIGHT ENG QUIT DUE TO AN INADEQUATE FUEL SUPPLY. A RQST OF ATC FOR VECTORS TO THE CLOSEST ARPT WAS MADE. WITNESSES OSRVD THE ACFT CIRCLE THE ARPT SEVERAL TIMES WITH THE PIC STATING HE WAS CONCERNED ABT THE PRESENCE OF SKY JUMPERS IN THE AREA. THE CONCERN INCREASED WHEN AN ACFT PULLED ONTO THE ACTIVE RWY AT THE LEXINGTON ARPT AFTER THE ACFT WAS COMMITTED TO LAND. WITNESSES INDICATED THE ACFT LANDED NOSE WHEEL FIRST AND CAREENED TO THE RT SIDE OF THE RWY AND OFF INTO SOFT TERRAIN. DIRECTIONAL CONTROL WAS LOST AS THE ACFT DPTD THE RWY, FOLLOWED SHORTLY BY A LEFT GEAR COLLAPSE AND SEPERATION, AND NOSE GEAR COLLAPSE. REMAINING FUEL AT THE ACCIDENT SITE WAS DETERMINED TO BE 9 GALLONS IN THE LEFT WING TANK AND NONE IN THE RIGHT.
