## Sequence of events

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

- Loss of engine power(total) - nonmechanical, descent - normal
  - fluid,fuel - exhaustion (cause)
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - in-flight planning/decision - poor, pilot in command (cause)
- Forced landing, descent - emergency
- Hard landing, landing - flare/touchdown
  - autorotation - improper, pilot in command (cause)

## Analysis

AFTER RECEIVING INFORMATION OF EXISTING UNFAVORABLE WIND CONDITIONS AND THAT FUEL WAS NOT AVAILABLE AT THE PLANNED REFUELING POINT THE PILOT ELECTED TO CONTINUE THE FLIGHT WITHOUT REFUELING. AS HE DESCENDED ON APPROACHING HIS DESTINATION THE ENGINE FAILED DUE TO FUEL EXHAUSTION. THE PLT MADE A HARD AUTOROTATIVE LANDING.
