Circumstances
Before departure, the pilot did not visually inspect the fuel tank. The fuel gauge indicated 17–18 gallons of fuel. Based on that reading, the pilot decided against refueling and departed.
Flight and Engine Failure
About 60 minutes into the flight, the low fuel light illuminated and the gauge showed 5 gallons. The pilot then climbed from 400 to 800 feet, a maneuver that took four minutes. After reaching 800 feet, the engine began to sputter and shortly thereafter stopped producing power. At that point, the fuel gauge indicated empty.
Forced Landing
The pilot executed a forced landing to a clearing. During the landing, the helicopter struck pine trees and rolled over onto its right side.
Post-Accident Examination
Examination of the helicopter revealed that there was no fuel inside the fuel tank. According to the flight manual, the low fuel light illuminates when there is one usable gallon of fuel remaining in the tank. The manual also states that when the low fuel light illuminates, the pilot should land immediately. The pilot reported that there were no mechanical deficiencies with the helicopter.
