## Probable cause

PILOT'S FAILURE TO MAINTAIN CLEARANCE FROM A ROAD SIGN DURING LANDING GROUND ROLL. A FACTOR IN THE ACCIDENT WAS THE FAILURE OF THE ENGINE EXHAUST SYSTEM WHICH RESULTED IN HIGH ENGINE OIL TEMPERATURE.

## Sequence of events

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

- On ground/water collision with object, landing - roll
  - object - sign
  - exhaust system - failure,total (contributing factor)
  - emergency procedure - performed, pilot in command
  - clearance - not maintained, pilot in command (cause)

## Analysis

THE ACFT ENGINE EXHAUST SYSTEM FAILED DURING CRUISE FLT, WHICH ALLOWED EXHAUST GAS ONTO THE ENGINE OIL PAN, CAUSING A RAPID RISE IN ENGINE OIL TEMPERATURE. THE PILOT ELECTED TO MAKE A PRECAUTIONARY LDG ON A PUBLIC ROAD. THE ACFT IMPACTED A ROAD SIGN DURING GROUND LANDING ROLL AND THE PILOT LOST CONTROL. THE ACFT NOSED DOWN, STRUCK THE GROUND AND CARTWHEELED.
