On June 28, 2003, a Stugart VANS RV-6A (registration N29PT) was involved in an aviation accident near Fort Collins, CO. Investigators recorded the probable cause as: the pilot's improper preflight planning/decision resulting in the fuel selector positioned improperly and fuel starvation, and his failure to maintain adequate airspeed. A factor contributing to the accident was the low altitude. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
Witnesses observed an airplane climb east after takeoff, then turn back when the engine stopped. It departed controlled flight and crashed near the airport. The fuel selector was found in the 'Off' position, and no fuel was in the carburetor. Toxicology showed stimulants in the pilot's urine.
Accident Sequence
Witnesses reported that the airplane had just taken off and was climbing to the east when they heard the engine stop. The airplane then turned around towards the airport, departed controlled flight, and impacted the ground near the southeast corner of the airport. Witnesses also noted hearing the engine sputter during the attempted return.
Post-Accident Examination
An examination of the airplane revealed witness marks on the cockpit floor panel consistent with the fuel selector valve handle being in the "Off" position at the time of impact. The engine intake valves and spark plugs showed evidence consistent with operating the engine with a lean mixture. Removal of the number 3 cylinder bottom spark plug revealed a smell of alcohol, consistent with the use of starter fluid. No evidence of fuel was found in the carburetor. No other anomalies were discovered.
Toxicological Findings
FAA toxicology testing of the pilot detected concentrations of Ephedrine, Pseudoephedrine, and Azacyclonol in urine.
