N4540C

Air Tractor AT-502

Analysis

During an application run the engine lost power. The pilot reported that there was 'not enough field left to land' and that the aircraft could not make it over the trees at the end of the field. The aircraft impacted the trees and came to a stop in a small field. Examination of the fuel system revealed a foreign substance in the main fuel filter. The fuel tank sump drain was leaking fuel and fuel was found in all fuel lines and the fuel control. A postaccident examination and teardown of the engine was completed on 4/4/96, and no anomalies were found that would prevent normal engine operation.
