N74586

On December 13, 2022, at 0925 central standard time (CST), a Mooney M20B, N74586, was substantially damaged when it was involved in an accident in Kellyton, Alabama. The pilot was fatally injured. The airplane was operated by the pilot as a positioning flight conducted under the provisions of Title 14 Code of Federal Regulations Part 91.

Review of FAA air traffic control and ADS-B data revealed that the airplane departed runway 36 at Perry-Houston County Airport (PXE), in Perry, Georgia, about 0825 on an instrument flight rules (IFR) flight plan to Bessemer Airport (EKY), Bessemer, Alabama. After departure, the airplane turned toward the west and climbed to an altitude of 6,000 ft msl.

About 0918, the pilot transmitted “mayday” several times and advised the controller that he was experiencing a rough-running engine. At the controller’s questioning, the pilot confirmed that he wanted to divert to the nearest airport and the controller provided course guidance to Thomas C Russell Field Airport (ALX), Alexander City, Alabama, which he estimated to be about 8 miles away. Postaccident review of the airplane’s flight track data showed that the airplane was about 11 nautical miles (nm) northeast of the airport at this time.

Shortly after the pilot initiated a left turn to ALX, he reported that the engine was once again producing power; however, he wanted to continue to the nearest airport. The controller provided the weather conditions at ALX, which included an overcast ceiling at 800 ft above ground level and 10 statute miles visibility. The pilot indicated that he was in instrument meteorological conditions, and the controller continued to provide headings toward the airport. About four minutes after reporting that the engine power was restored, the pilot made a radio call stating, “I’m engine out.” Radio and radar contact were lost shortly thereafter about 5.8 nm north-northeast of the airport.

A witness near the accident site reported that he heard tree branches breaking and looked up to see the airplane “clipping the trees.” He indicated that the airplane appeared to be level and stated that there was no engine noise. Video obtained from the property owner showed the airplane impacting trees before rolling inverted and descending nose-first to the ground. The wreckage was located 5.5 nm north of ALX and about 1.25 nm west of the airplane’s last radar-observed position.

The pilot’s logbook indicated that he had accrued 370.6 total hours of flight experience, with 18 hours in actual instrument conditions, as of September 4, 2022. There were no entries in the pilot’s logbook after that date. In a post made by the pilot to a social media account on November 9, 2022, he stated that he had reached a total of 520 hours of flight experience. The pilot had received his instrument rating, commercial pilot certificate, and multi-engine land rating all within the 9 months before the accident.

The airplane owner reported that the pilot worked for him flying various airplanes that the owner managed. The pilot had flown the accident airplane make and model for the first time on a repositioning cross-country flight the day before the accident, lasting about one hour or less. The airplane’s owner reported that the pilot received “at least an hour” of ground instruction on the accident airplane.

The pilot sent a text message to a friend after the flight the previous day asking if the autopilot worked in the accident airplane. The friend replied no, and that “it never has.” The pilot subsequently asked, “…do you have to swap fuel tank sides in the Mooney like an archer/warrior or does it all crossfeed?” The friend replied that switching tanks was required, and stated that he did so every 45 minutes. The pilot subsequently stated that while he had not done so during the previous flight, he would during the next flight.

A witness who drove the pilot to the airport on the morning of the accident recalled the pilot stating before the flight that he hoped the airplane was already fueled so that he could get started on his pre-flight checks. The witness also stated that the employee at the airport told him that the plane was, “fueled and ready,” and that the pilot took a picture of the fuel receipt with his phone.

The airplane’s most recent annual inspection was completed on December 8, 2022, at tachometer time of 3,361.8 hours. The tachometer at the time of the accident indicated 3,365.9 hours. The accident pilot would have flown about 2 of the 4.1 hours since the annual inspection was completed.

A review of the pilot’s logbooks as well as social media posts indicated that a significant portion of his recent flight experience had been flown in airplanes that either did not require the switching of fuel tanks in flight, or in Piper airplanes, in which the fuel selector valve was painted red and located on the sidewall on the pilot’s left side. In the accident airplane make and model, the fuel selector is painted black and located on the floor beneath the pilot’s seat, as described by the airframe manufacturer.

Fuel consumption calculations based on the pilot’s operating handbook and supplement indicated that the airplane would have consumed about 10.15 gallons between engine start and the pilot’s first mayday call. The airplane had a Supplemental Type Certificate modification for bladder fuel tanks that should have allowed the airplane to carry a total of 54.8 gallons, or 27.4 gallons of usable fuel in each of the fuel tanks; however, the STC did not list the Model M20B as applicable to receive this modification, therefore, the actual fuel capacity of the accident airplane could not be determined.

Fuel logs from Waycross-Ware County Airport (AYS), Waycross, Georgia, showed that 22.2 gallons of fuel were purchased the day before the accident. A photo of a fuel receipt obtained from the pilot’s personal phone reflected a purchase of 38.2 gallons of fuel at PXE; however, the registration number depicted on the receipt was that of a different airplane, and not of the accident airplane.

Examination of the wreckage at the accident site revealed that the airplane came to rest inverted in a pasture, . All portions of the airplane were intact, except for the outermost portion of the left wing, including the left aileron, which was located at the base of large trees about 68 ft from the main wreckage. The fractured outermost portion of the left wing exhibited leading edge damage consistent with tree impact while in a left turn.

The propeller hub with propeller blades attached was impact-separated from the engine and embedded at the ground impact point. Examination of the propeller revealed that both blades exhibited minimal chordwise rotational scoring on the face sides and no remarkable twisting. One of the blades exhibited aft bending. The engine compartment and cockpit area were impact-crushed aft, and the fuselage and empennage were substantially damaged. The engine control levers were in their full forward positions. The engine turbocharger control lever was in the full aft position.

Control continuity was established from the rudder and elevator cockpit flight controls to the flight control surfaces; however, aileron control continuity could not be established due to impact damage at both wing roots. The main landing gear remained in the wheel wells, while the nose landing gear had been pulled out of the wheel well through impact forces. The flaps were found in the full up position.

Visual examination of the airframe revealed that the wing fuel bladders remained intact. While there was evidence of fuel leakage with clear signs of staining from the left wing fuel vent, the right wing remained clean with no evidence of fuel leakage or fuel blighting in the area surrounding the wing. The left tank fuel leak was plugged and about 18 gallons of remaining fuel was drained from the left fuel tank, while the right tank was found empty. No fuel was found in the fuel hoses and fuel system components. The fuel selector was observed positioned to the right wing tank.

Postaccident examination of the engine revealed that the sparkplug electrodes showed coloration and wear consistent with normal operation when compared to a Champion Check-A-Plug chart. Thumb suction and compression were attained on all cylinders when the crankshaft was rotated manually. Crankshaft and camshaft continuity were confirmed throughout the engine. A visual inspection of the cylinders revealed normal coloration and condition of the piston faces. The magnetos produced sparks on all leads when removed and rotated by hand. The carburetor was disassembled, and its fuel inlet screen removed. The fuel screen was free from debris and unobstructed. No fluid or sediment was present in the float bowl. The floats were of the black plastic style and moved freely throughout their travel range. Suction and expulsion were noted at the respective ports on the engine-driven fuel pump when rotated using an electric drill. No fuel was found in the fuel lines during the examination.
