## Sequence of events

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

- Loss of engine power, maneuvering
  - fluid,fuel - exhaustion (contributing factor)
  - fuel supply - inadequate, pilot in command (cause)
  - in-flight planning/decision - improper, pilot in command (cause)
- Forced landing, maneuvering
- Hard landing, landing - flare/touchdown
  - terrain condition - downhill (contributing factor)
  - terrain condition - none suitable (contributing factor)

## Analysis

A FORCED LANDING DOWNHILL WAS MADE DUE TO A LOSS OF POWER. UPON TOUCHDOWN THE RIGHT SKID BROKE AND THE AIRCRAFT ROLLED ONTO ITS RIGHT SIDE. DURING ENGINE EXAMINATION ONLY 1PINT OF FUEL WAS REMAINING IN THE FUEL TANK. THE ENGINE WAS TEST RUN AND NO MECHANICAL REASON FOR A POWER LOSS COULD BE FOUND.
