## Probable cause

OIL FOULING OF THE WINDSHIELD DUE TO A LOOSE ENGINE OIL SEAL. A FACTOR WAS THE PILOT'S PREEXISTING VISION IMPAIRMENT.

## Sequence of events

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

- Miscellaneous/other, cruise - normal
  - lubricating system,oil seal - loose (cause)
  - fluid,oil - dumped
  - window,flight compartment window/windshield - dirty(foggy) (cause)
  - precautionary landing - attempted, pilot in command
- Overrun, landing
  - go-around - initiated, pilot in command
- In flight collision with object, maneuvering - turn to landing area (emergency)
  - object - tree(s)
  - visual lookout - restricted, pilot in command (cause)
  - physical impairment(visual deficiency), pilot in command (contributing factor)

## Analysis

DURING CRUISE FLIGHT, OIL BEGAN COVERING THE WINDSHEILD. THE PILOT PREFORMED A PRECAUTIONARY LANDING IN A FIELD BUT DURING THE LANDING ROLL, OBSERVED A FENCE AHEAD. HE APPLIED POWER TO CLEAR THE FENCE. BECAUSE HE HAS NO USEFUL VISION IN THE LEFT EYE, HE BANKED THE AIRPLANE TO THE RIGHT TO LOCATE A SUITABLE LANDING LOCATION. DURING THE TURN THE RT WING COLLIDED WITH A TREE. ENGINE EXAMINATION REVEALED THE CRANKSHAFT OIL SEAL WAS PARTIALLY EXTRUDED. THIS ALLOWED OIL TO EXIT THE ENGINE. THE ENGINE HAD ACCUMULATED 176.5 HRS SINCE OVERHAUL.
