## Probable cause

FAILURE OF THE PILOT TO ADEQUATELY DETECT WATER CONTAMINATION IN THE AIRPLANE'S FUEL SYSTEM DURING PREFLIGHT.

## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - fluid,fuel - water (cause)
  - preflight planning/preparation - inadequate, pilot in command (cause)
- Forced landing, landing - flare/touchdown
- In flight collision with object, landing - flare/touchdown
  - object - vehicle

## Analysis

THE PILOT WAS CONDUCTING A MAINTENANCE TEST FLIGHT FOLLOWING AN ANNUAL INSPECTION AND REPLACEMENT OF TWO CYLINDERS. SHORTLY AFTER TAKEOFF THE ENGINE LOST POWER. A FORCED LANDING WAS MADE TO A HIGHWAY AND THE AIRPLANE COLLIDED WITH 2 MOVING MOTOR VEHICLES. EXAMINATION OF THE ENGINE REVEALED EVIDENCE OF WATER IN THE CYLINDERS. THE AIRPLANE HAD BEEN SITTING FOR SEVERAL MONTHS WITHOUT THE FUEL TANKS TOPPED OFF.
