HISTORY OF FLIGHTOn October 6, 2019, at 0849 central daylight time, an experimental, amateur-built Lancair Legacy airplane, N10LG, was destroyed when it was involved in an accident near Bixby, Missouri. The private pilot was fatally injured. The airplane operated as Title 14 Code of Federal Regulations Part 91 personal flight.

The pilot flew the airplane from Texas to Missouri three days earlier to attend the Lancair Owners and Builder Organization's annual meeting; the accident occurred on the return flight. According to the Federal Aviation Administration (FAA), there was no record of the pilot obtaining a weather briefing or filing a flight plan before his departure.

Radar information showed the airplane depart about 0825 and establish a south-southwesterly heading at altitudes between about 2,300 ft mean sea level (msl) and 2,800 ft msl. About 0846, the airplane began a descent and reached a minimum altitude about 1,525 ft msl about 0849. Over the next minute, the airplane entered a climbing, 270° left turn and slowed to a speed of about 42 kts before radar contact was lost at 0849:49, at an altitude of 1,975 ft msl. A witness about 3 miles from the accident site heard a single-engine airplane and reported that the engine sounded as though it was "revving high." He stated that it was "a bad day to be flying" because of the thick cloud cover and mist. He estimated that when the airplane passed over him, it was a few hundred feet above the ground or lower, and that he could not see it due to the low, thick cloud cover. Another witness said that she heard a low-flying airplane and then the sound of impact. She described the weather as being overcast and "very low clouds." She added that, if the pilot had been below the clouds, "he would have been flying very low, nearly at tree top at the top of the hills."

The Civil Air Patrol received an emergency locator transmitter (ELT) signal and began an aerial search. The wreckage was located about 1615 about 5 miles south of Bixby, Missouri, in the Mark Twain National Forest.

PERSONNEL INFORMATIONThe pilot held four Repairman- Experimental Aircraft Builder certificates. A partial copy of the pilot's logbook contained entries from October 22, 2018, to September 23, 2019 and indicated that the pilot had logged 108.6 hours in the accident airplane. During that time period, the pilot recorded .5 hrs actual instrument experience in September 2018.

METEOROLOGICAL INFORMATIONThe 0751 weather observation at Lambert-St. Louis International Airport (STL), located 7 miles east of the departure airport, included wind from 020° at 7 knots, 10 miles visibility, scattered clouds at 3,700 ft above ground level (agl), a broken ceiling at 2,000 ft agl, temperature 17°C, dew point 9°C, and an altimeter setting of 30.13 inches of mercury.

About the same time, the weather at Waynesville-St. Robert Regional Airport-Forney Field (TBN), Fort Leonard Wood, Missouri, located about 60 miles west of the accident site, included wind from 030° at 6 knots, 10 miles visibility, an overcast ceiling of 2,000 ft agl, temperature 15°C, dew point 10°C, and an altimeter setting of 30.12 inches of mercury. The cloud ceiling was reported in the remarks section as 1,900 ft agl.

WRECKAGE AND IMPACT INFORMATIONThe airplane impacted heavily-wooded terrain in a flat attitude on a magnetic heading of 263°. Although there were some broken branches in the area, no trees had been toppled. The right wing separated 90° forward at the spar carry-through. The left wing remained attached.

The empennage was displaced to the right but remain attached to the fuselage. The engine remained attached but was displaced to the left. The 3-blade metal propeller separated from the crankshaft and was located next to the engine. One blade was relatively straight, the second blade was bent, and the third blade displayed s-bending and 90-degree chordwise scratches on both the cambered and flat surfaces. The propeller spinner was crushed to the right but remained attached to the hub. Examination of the airframe and engine revealed no anomalies that would have precluded normal operation.

MEDICAL AND PATHOLOGICAL INFORMATIONToxicology testing performed by FAA's Forensic Sciences Laboratory found 54 mg/dL and 18 mg/dL ethanol in muscle and brain tissue, respectively. Putrefaction was noted. No drugs were detected in liver tissue.
