Narrative:

An exhaust stack fire occurred during a start attempt. The battery was worn down from earlier attempts [at starting. The fire was extinguished with the extinguisher installed in the aircraft. Although no external damage was evident, the cowling was removed to inspect further. While the cowling was off, the battery was charged. The mechanic on the field felt the engine needed work before flight. There was no damage from the fire. I felt the aircraft was airworthy, discussed it with my director of maintenance and continued the flight west/O any problems. The operator at the airport reported to the FAA the events of the morning. They reported the possibility of an unairworthy aircraft. Callback conversation with reporter revealed following information. Reporter stated that the director of maintenance for the company was not on the airport and thus could not personally inspect the aircraft, nor did the FBO mechanic communication with the director of maintenance. The reporter's company and the firm for which the mechanic worked are competitors in the state. The reporter feels it possible that the mechanic was looking for business. The FAA requested a written report, but has declined to pursue the matter further. After arrival back at home base, the aircraft was inspected and found to be airworthy.
