Analysis

The airplane was being used for pipeline patrol. During the flight, the engine ran rough twice and twice the commercial pilot made off airport landings to drain the sumps in the fuel system. Shortly after the next takeoff, the engine quit and the pilot had to make a forced landing in a rough sugar-cane field. Post accident investigation revealed that the airplane had previously been out of service for three years. The mainenance personnel that returned the airplane to service, stated they had used the maintenance manual to remove the airplane from storage, and back to service. Investigation indicated all parts of the fuel system were covered with a rust colored, varnish like substance.
