Probable cause

The pilot’s improper preflight planning and in-flight fuel management, which resulted in fuel starvation and a total loss of engine power. Also causal to the accident was the pilot’s failure to see and avoid the wires on the airport boundary.

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 departed on the 40-mile flight with an unknown quantity of fuel onboard the airplane, but he estimated that it had about 10 gallons more than he thought was needed for the flight. While maneuvering to land, he increased the engine power twice, but the engine did not respond. He anticipated that the airplane could land on the airport property; however, the airplane struck wires and terrain short of the runway. Seven gallons of fuel were recovered from the 78.6-gallon fuel system, of which 3 gallons were unusable. The amount of fuel recovered from each tank could not be determined, and which tank the pilot had selected at the time of the loss of engine power could also not be determined. However, after the accident, the pilot reported that data from the airplane's engine monitor revealed that the fuel flow stopped 60 seconds before the propeller stopped. He added that he probably should have purchased fuel before his departure and that, if he had it to do over, he would. After replacing the damaged propeller with a slave propeller and adding 5 gallons of fuel in each wing tank, an engine test run was conducted; the engine started immediately, accelerated smoothly, and ran continuously without interruption throughout the test.

Factual narrative

The pilot reported that he downloaded the data from the airplane's engine monitor, and stated, "…60 seconds before the propeller stopped, there was no fuel flow…" He added that he probably should have purchased fuel before his departure from OBI, and that if he had it to do over, he would. On June 25, 2014, the airplane was secured to a flatbed trailer in Georgetown, Delaware. A slave propeller was installed in place of the damaged propeller and the airplane was serviced with 10 gallons of aviation fuel; 5 gallons in each wing tank. An external battery was connected at the external power plug, and an engine start was attempted. The engine started immediately, and was allowed to warm up at 1,000 rpm. The engine was accelerated to 1,500 rpm, and a magneto check was performed with satisfactory results. The engine was then accelerated smoothly to 2,400 rpm, where it ran without interruption until stopped by the engine controls in the cockpit. During the engine run, the fuel selector was switched four times between the left and right tanks, and the engine ran continuously and without interruption each time. According to FAA records, the airplane was manufactured in 1979. On August 31, 1995, a 305-horsepower Teledyne Continental TSIO-520-NB engine modified under Supplemental Type Certificate (STC SE022SE) by Rocket Engineering Corporation was installed. Its most recent annual inspection was completed June 10, 2013, and the airplane had accrued 91 hours since that date. He estimated the airplane had accrued 3,000 total aircraft hours. According to Rocket Engineering Corporation, the fuel consumption rate during a maximum-power climb was up to 33 gallons per hour. The fuel consumption rate between an economy-cruise setting and maximum-cruise setting was 15 to 25 gallons per hour. According to the Mooney M20K Pilot Operating Handbook, the fuel capacity of the airplane was 78.6 gallons, of which 75.6 gallons were usable. On May 18, 2014, at 0959 eastern daylight time, a Mooney M20K, N200DP, was substantially damaged when it collided with power lines and terrain following a total loss of engine power while on approach to Sussex County Airport (GED), Georgetown, Delaware. The airline transport pilot was seriously injured. Visual meteorological conditions prevailed, and no flight plan was filed for the flight, which departed Woodbine Municipal Airport (OBI), Woodbine, New Jersey, about 0935. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. The pilot stated that his was one airplane in a flight of four from OBI to GED, where they planned to purchase fuel and have brunch. He estimated the 40-mile flight would consume approximately 6 gallons of fuel and he estimated there were "15 to 20 gallons" on board at departure. The en route portion of the flight was flown at 4,500 feet and the pilot entered the airport traffic pattern for landing on runway 04. The downwind leg was extended due to traffic, and whileon downwind, the pilot switched from the left fuel tank to the right fuel tank, lowered the landing gear, moved the propeller lever to "full," completed "landing checks," and turned to the base leg of the traffic pattern. According to the pilot, as he turned from the base leg to the final leg of the traffic pattern, he attempted to increase engine power, but "there was nothing there" and the engine would not advance past 1,000 rpm. He again attempted to increase power with no response from the engine, and switched the fuel selector back to the left fuel tank. The pilot believed he "had the field made," but the airplane impacted power lines, and came to rest near the airport boundary At 0954, the weather conditions reported at GED included a broken ceiling at 7,500 feet, visibility 10 miles, temperature 16 degrees C, dew point 6 degrees C, and an altimeter setting of 30.22 inches of mercury. The wind was from 010 degrees at 6 knots. The pilot held an airline transport pilot certificate with a rating for airplane multiengine, and a commercial pilot certificate with a rating for airplane single engine land. His most recent FAA third class medical certificate was issued on April 30, 2011. He reported 5,000 total hours of flight experience, of which 400 hours were in the accident airplane make and model. The wreckage was recovered from the accident site and moved onto GED airport property, where it was secured for examination at a later date. During recovery, a total of approximately 7 gallons of fuel was recovered, but the exact amounts recovered from each wing tank could not be determined. Examination of photographs revealed substantial damage to the wings, fuselage, and empennage. All three propeller blades were damaged, with one blade cut and scored deeply near its root.
