Shortly after departing Flint, the airplane's left engine started to surge. The airplane also began experiencing intermittent electrical surges causing the instrument panel lights, cabin lights, and radios to go OFF and ON. The pilot stated that he decided to divert to Detroit and land because the airport had emergency equipment available. The pilot stated that he did not advise ATC of any problem while diverting because he believed that he could land without incident. The pilot did not attempt to secure the left engine before landing because it was still developing some usable power. The airplane landed on the runway gear up.

Probable Cause:

PROBABLE CAUSE: "The pilot's failure to extend the landing gear. A factor in the accident was the pilot's diverted attention."
