Probable cause
A loss of engine power due to fuel exhaustion as a result of the pilot’s improper fuel planning.
Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The pilot stated that he normally fueled the helicopter with 200 pounds of fuel each time he loaded chemicals, which equated to approximately 30 minutes of engine endurance. During the flight he did not recall the 20-minute fuel warning light or any other warning lights illuminating. After what the pilot thought was about 15 minutes into the flight, the helicopter yawed from side-to-side and the engine experienced a total loss of power. The pilot performed a quick-stop landing, severing the tail boom. Federal Aviation Administration inspectors found no fuel in the fuel line and only a half of a cup of fuel in the fuel filter. While the fuel tank had been compromised, there was no evidence of fuel in the surrounding area.
Factual narrative
On July 31, 2010, approximately 1200 central daylight time, a Garlick OH-58A, N305SD, operated by Coastal Air Service, Panama City, Florida, was substantially damaged when the pilot made a quick-stop landing after the engine lost power 10 miles east of Kountze, Texas. Visual meteorological conditions (VMC) prevailed at the time of the accident. The aerial application flight was being conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 137 without a flight plan. The pilot, the sole occupant on board, received serious injuries. The local flight originated near Kountze, Texas, approximately 1130. The pilot reported the helicopter yawed from side-to-side, then the engine lost power. The pilot performed a quick-stop landing, severing the tail boom. The pilot told FAA inspectors that he normally fueled to 200 lbs each time he loaded chemicals, and this gave him approximately 30 minutes endurance. He did not recall the 20-minute fuel warning light or any other warning lights illuminating. He thought he had flown only 15 minutes. FAA inspectors found no fuel in the fuel line and only 1/2-cup of fuel in the fuel filter. The fuel tank had been compromised. An FAA inspector responded to the accident site and found the helicopter in an upright position. He could not access the fuel filler cap to see how much fuel was in the tank. There was no fuel in the line between the fuel control and the engine fuel nozzle. When the main fuel filter was opened (and after letting the fuel filter drain back into the housing), less than 1/2-cup of fuel was noted. There was no fuel smell in the area.
