## Probable cause

THE PILOT'S POOR PREFLIGHT PLANNING/PREPARATION AND FUEL CONSUMPTION CALCULATIONS.  THE ROUGH/UNEVEN TERRAIN IS A FACTOR IN THIS ACCIDENT.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, cruise
  - fluid,fuel - exhaustion (contributing factor)
  - preflight planning/preparation - poor, pilot in command (cause)
  - fuel consumption calculations - poor, pilot in command (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, descent - emergency
  - terrain condition - rough/uneven (contributing factor)

## Analysis

THE AIRCRAFT SUSTAINED A TOTAL LOSS OF POWER DURING CRUISE FLIGHT.  THE PILOT TRANSMITTED A 'MAYDAY CALL' AND EXECUTED AN EMERGENCY LANDING. DURING THE LANDING ON THE ROUGH/UNEVEN TERRAIN, THE AIRCRAFT NOSED OVER ONTO ITS BACK.  THE WRECKAGE EXAMINATION DISCLOSED NO EVIDENCE OF ANY FUEL IN THE FUEL SYSTEM.
