## Probable cause

THE CONTAMINATION OF THE AIRCRAFT FUEL SYSTEM WITH ICE AND WATER, WHICH WAS UNDETECTABLE BY THE PILOT.

## 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 - ice (cause)
  - fluid,fuel - water (cause)
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT HAD PREFLIGHTED HIS AIRCRAFT AND FOUND WATER IN THE RIGHT FUEL TANK.  A MECHANIC WHO WAS ASSISTING THE PILOT NOTED THAT THE WATER FROZE INSTANTLY WHEN IT CONTACTED THE OUTSIDE AIR.  THE PILOT CONTINUED TO DRAW WATER UNTIL NO EVIDENCE OF WATER REMAINED IN THE FUEL SYSTEM.  DURING CRUISE FLIGHT, THE ENGINE LOST POWER AND THE AIRPLANE COLLIDED WITH TREES AND TERRAIN.  AN INSPECTION OF THE WRECKAGE REVEALED ABOUT 5 OUNCES OF WATER IN THE LEFT HEADER TANK, AS WELL AS WATER IN THE FUEL MANIFOLD (SPIDER).  THE ENGINE WAS TEST RUN ON THE AIRFRAME AFTER THE ACCIDENT.  NO EVIDENCE OF MALFUNCTION OR FAILURE WAS FOUND.
