N3659T
Air Tractor AT-301
The airplane was substantially damaged during a forced landing following a loss of engine power. The terrain was soft and rough, causing the aircraft to nose over prior to coming to a rest. The aircraft was most recently fueled with 100 gallons and consumed approximately 35 gallons/hour during flight. The pilot estimated the total flight time since refueling as 2-1/2 to 3 hours, accumulated over two or three flights. A total of 4 gallons of fuel were recovered from the aircraft after the accident. Unusable fuel was listed at 6 gallons according to the Federal Aviation Administration Type Certificate Data Sheet. No evidence of fuel contamination was present. A post-accident examination of the aircraft and engine did not reveal any pre-impact anomalies. The pilot stated that the "most probable cause [of the accident was a] lack of fuel."
On June 20, 2003, at 0940 eastern daylight time, an Air Tractor AT-301, N3659T, operated by Robertson Crop Dusting Service Inc., sustained substantial damage during a forced landing 7 miles south of South Haven Area Regional Airport (0D1), South Haven, Michigan. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 137 aerial application flight was not operating on a flight plan. The pilot reported minor injuries. The local flight departed 0D1 at 0840. The pilot stated he was returning to 0D1 after the local flight when the engine backfired twice. He reported that he landed in a field, however, the terrain was sandy and rough. The aircraft subsequently nosed over prior to coming to rest. The pilot stated that the aircraft had been fueled with approximately 100 gallons one or two flights prior to the accident flight. The aircraft's normal fuel consumption was about 35 gallons/hour, according to the pilot. He estimated the total flight time since refueling had been 2-1/2 to 3 hours. Approximately four gallons of fuel were recovered from the aircraft after the accident. The aircraft's type certificate data sheet lists a maximum fuel capacity of 126 gallons with 120 gallons useable. The pilot reported no malfunctions with the airplane prior to the loss of engine power. A post-accident examination of the aircraft and engine did not reveal any pre-impact anomolies. No evidence of fuel contamination was present. The pilot stated that the "most probable cause [of the accident was a] lack of fuel."
Failure of the pilot to verify fuel quantity prior to the accident flight, and fuel exhaustion resulting in a loss of engine power. Contributing factors were the soft, rough, unsuitable terrain for a forced landing.
