## Sequence of events

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

- Loss of engine power, approach - vfr pattern - downwind
  - fuel system,pump - overtemperature (cause)
  - fluid,fuel - starvation (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s) (contributing factor)

## Analysis

FLT EXPERIENCED TOTAL LOSS OF ENGINE POWER WHILE ON A DOWNWIND POSITION FOR LANDING.  THE RUNWAY COULD NOT BE REACHED AND A FORCED LANDING WAS MADE IN TREES.  THE FUEL PUMP WAS MOUNTED DIRECTLY TO THE ENGINE BLOCK AND AUTO FUEL WAS BEING USED. AFTER THE ACCIDENT THE ENGINE WAS OPERATED ON THE AIRCRAFT TO FULL POWER WITH NO EVIDENCE OF FAILURE OR MALFUNCTION. THE CONDITIONS WERE CONDUCIVE FOR FUEL VAPOR LOCK.
