A charter pilot landed in a small lake after total power loss; an oil-fed fire during ground run destroyed the aircraft. Investigation found fuel starvation due to improper flight planning and inadequate record keeping.

Incident Overview

A pilot operating an on-demand fishing/hunting charter flight experienced a total loss of engine power and subsequently landed the aircraft in a small lake. During the ground run following the emergency landing, an oil-fed fire engulfed and destroyed the aircraft.

Investigation Findings

Investigators discovered inadequate documentation regarding flight following, as well as missing fuel records and maintenance records for the accident aircraft and its operation. Passenger witnesses reported that the fuel gauges indicated low fuel levels prior to takeoff. Examination of the fuel pump showed evidence of fuel starvation.
