On January 31, 1997, a Bellanca 17-30A (registration N6638V) was involved in an aviation accident near Scottsdale, AZ. Investigators recorded the probable cause as: fuel exhaustion due to the pilot's improper fuel management. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot reported engine power loss to idle during approach despite throttle input. Fuel gauge indicated 1/4 tank. Switching tanks did not restore power. Investigation found fuel selector on left outboard tank and outboard tanks empty.
Incident Summary
During approach to an airport, a pilot contacted the FAA control tower and was instructed to report on a long right base for runway 21. Approximately 4 miles from the airport, the engine suddenly dropped to idle power. The pilot noted that the throttle had no effect on engine rpm. He immediately checked the fuel gauge, which indicated about 1/4 tank remaining. Attempts to switch fuel tanks did not result in a restart or any increase in engine power from idle.
Investigation Findings
FAA inspectors examined the aircraft after the incident. The fuel selector was found positioned on the left outboard fuel tank. Additionally, both outboard fuel tanks were determined to be empty. No other abnormalities or contributing factors were documented. The aircraft's fuel system operation and pilot actions were consistent with the observed conditions.
