Location: Minneola, FL
Accident Number: ERA19FA256
Date & Time: 08/23/2019, 1115 EDT
Registration: N9143M
Aircraft: MORIARTY MARVIN AVENTURA II
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General Aviation - Personal 

On August 22, 2019, about 1115 eastern daylight time, an experimental amateur-built Aventura II, N9143M, was substantially damaged by impact with terrain shortly after takeoff from Florida Flying Gators Ultralight Flightpark (3FD4), Minneola, Florida. The private pilot was fatally injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight that was destined for Deland Municipal Airport-Sidney H Taylor Field (DED), Deland, Florida. The airplane was owned and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91.

The pilot's son stated he and his father put the airplane together after it was purchased the preceding year. He stated he and his father installed an after-market supercharger on the engine several months before the accident and the airplane had been flying very good since. About two days before the accident, his father stated that the airplane has been experiencing higher than normal fuel consumption going from the normal 4 gallons an hour to about 6 gallons an hour.

The day before the accident flight, the pilot's son stated that he and his father replaced the jets in the carburetor to smaller jets to try and improve the fuel consumption. After they replaced the jets, they started the engine and it was running very rough (coughing and missing). The next morning, on the day of the accident, when the son showed up at the airport, his father told him he had fixed the airplane by adjusting the tabs on the carburetor's float bracket and allowing more fuel to enter the carburetor bowl. They performed a run-up of the engine and it ran normal. He further stated the plan was for his father to fly to DED and he would drive the truck and trailer there to meet him. He watched as his father started his takeoff roll on runway 36. He stated the takeoff looked normal but noticed the airplane was not climbing like it had in the past. When the airplane reached about 300 feet agl, the engine started to sputter again and run rough. He stated it looked like his father tried to turn back to the runway and made a sharp left turn. Shortly after the left turn, he saw the airplane go straight down to the ground.

The pilot held a private pilot certificate, with a rating for airplane single-engine land. His most recent FAA third-class medical certificate was issued on October 15, 2018. He reported 306 total hours of flight experience at that time.

The two seat, high-wing, tail wheel airplane, was manufactured in 2001. It was powered by a supercharged Rotax 912ULS, 150-horsepower engine, equipped with a three-blade propeller. The most recent condition inspection was completed on April 1, 2019. At that time, the airframe and engine had 820.2 total hours of operation. The airplane had flown 50.5 hours since the inspection.

The airplane came to rest about 200 yards from the end of runway 36. The wreckage path was oriented on 270°, and all major components were located with the main wreckage. Flight control continuity was verified from the cockpit to all primary flight controls surfaces.

Examination of the wreckage revealed that the airplane hit almost in a vertical nose down attitude. The nose of the airplane was fractured in several pieces and the instrument panel was destroyed. The instruments were laying in the grass beside the main wreckage. The landing gear was down. The top wing was impact damaged and the fabric was torn down the entire length of the wing. The aluminum tubing inside the wing structure was fractured off and torn through the wing fabric material. The engine fractured off the engine mounts and remained connected through the wiring and cables from the throttle and mixture controls. The engine was found inverted and automotive gasoline was pouring out of the fractured fuel lines. The three blade composite propeller remained attached to the engine and one propeller blade was fractured mid-blade by impact forces. Both carburetors were fractured off the induction system and only connected by the throttle linkage. The tail section of the airplane did not make contact with the ground and was intact and undamaged.

The engine was further examined and found that the choke on the carburetors were safety wired in the open position. The right side exhaust gas temperature probe was cut off at the exhaust pipe. A new temperature probe was drilled into the exhaust pipe and clamped to the exhaust pipe with two worm style stainless steel clamps. An aftermarket supercharger had been installed on the rear of the engine. The supercharger spun freely, and no binding was noted. The top spark plugs were removed and noted to be black and sooty from exhaust gases. Thumb compression was established on all cylinders. A lighted boroscope was used to exam the cylinders, valves and pistons. No anomalies were noted.

The wreckage was retained for further investigation.
