The plt made a forced landing on a road where during the landing roll the acft collided with a fence and eventually came to rest in a ditch.

A fuel sample was taken which revealed a noticable quantity of residue particles containing silicon, iron, and aluminum. The sample met the minimum astm standards for 100LL fuel.
