On July 9, 1993, at 1030 Alaska daylight time, a wheel equipped Cessna 207 airplane, registered to and operated by Baker Aviation of Kotzebue, Alaska, experienced an in flight fire in the cabin under the right front seat. The scheduled flight, operating under 14 CFR Part 135, departed Nome, Alaska, and the destination was White Mountain, Alaska. A visual flight rules flight plan was filed and visual meteorological conditions prevailed. The Airline Transport certificated Pilot-in-Command and his passenger were not injured and the airplane received minor damage. According to Larry Williams, the Director of Operations for Baker Aviation, an electrical wire had been tie wrapped to a fuel line located under the cabin floor directly beneath the right front seat. The electrical wire was chaffed through the insulation and the fuel line had a hole. The fire was extinguished with a hand held fire extinguisher. The Operator could not determine who had done any work in the area of the fire.
