N30BJJordan Bruce C PITTS S2E · 2009

On March 8, 2017, at 1537 eastern standard time, an experimental amateur-built Pitts S2E, N30BJ, was substantially damaged after it impacted trees and terrain while on approach to Cox Airport (NC81), Apex, North Carolina. The commercial pilot was fatally injured. The airplane was registered to and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed, and no flight plan was filed for the personal local flight, which originated about 1500.

According to witnesses, the airplane was descending on approach to runway 9 at NC81. One witness reported that, when the airplane passed overhead, the engine "sounded like it was running perfectly." Another witness reported seeing the airplane approaching the runway at an angle before the airplane went out of her line of sight. A third witness stated that the airplane "rolled inverted" before it impacted a field about 300 feet short of the threshold of runway 9. Several witnesses reported that they heard two "booms."

According to Federal Aviation Administration (FAA) records, the pilot held a commercial pilot certificate with ratings for airplane single-engine land and instrument airplane. The pilot was issued an FAA third-class medical certificate on October 17, 2016. According to the pilot's logbook, he had accumulated a total of 1,933.2 hours of flight time. In the previous year, he had accumulated 9.4 hours of flight time, all of which were in the accident airplane.

According to FAA records, the two-place biplane was issued an airworthiness certificate on January 23, 2009. It was equipped with a 190-horsepower Lycoming HIO-360 series engine that drove a two-bladed Hartzell constant speed propeller. According to the airplane's maintenance logbooks, a condition inspection was completed on October 17, 2016, at a total time of 92.7 hours. Since that time, the pilot had flown the airplane for a total of 3.7 hours.

At 1537, Raleigh-Durham International Airport (RDU), Raleigh, North Carolina, located about 9 miles north of the accident location, reported the 2-minute average wind from 292° at 9 knots and the 5-second maximum average wind from 297° at 15 knots.

The observations from surrounding airports around the accident time indicated gusty surface wind conditions from the west through north. Wind gusts as high as 20 knots from 287° were observed as close as 12 minutes before the accident time at RDU.

The model sounding created for the accident site at 1500 indicated a surface wind from 295° at 10 knots with the wind remaining northwesterly through 10,000 ft. The wind increased in speed to 15 knots by 2,500 ft and to 30 knots by 9,000 ft. Light low-level wind shear was possible between the surface and 700 ft, and light to moderate clear-air turbulence was possible above 5,000 ft..

NC81 was a private airport located about 1 mile north of Apex, North Carolina, and it did not have an operating control tower. The airport was equipped with a turf runway designated as 9/27, which was 2,450 ft long by 75 ft wide. The airport elevation was 455 ft above mean sea level.

According to local pilots familiar with NC81, because of the sloped runway, some pilots would land with up to a 10-knot tailwind on runway 9 before they would decide to land into the wind on runway 27. The pilot's son stated that the pilot used runway 9 about 90% of the time, and, only used runway 27 if there was a strong wind.

The airplane impacted a pine tree before impacting the ground and came to rest, partially inverted, on the left wing. The fuselage was oriented on a 150° heading, and a ground scar was located about 15 ft before the main wreckage. A debris field began some distance beyond the pine tree and extended about 240 ft long on a 90° heading Flight control continuity was confirmed from the cockpit to all the flight control surfaces. The lower left wing was bent aft, and the outboard section was separated and scattered along the debris path. A section of the lower left wingtip was located in the vicinity of the initial tree strike. The upper left wing was partially separated. The right wings remained attached to the fuselage and were bent forward. The empennage remained attached to the fuselage. The right horizontal stabilizer and right elevator were undamaged. The vertical stabilizer and rudder remained attached to the empennage, incurred skin damage, and were slightly bent. The left horizontal stabilizer and left elevator remained attached to the empennage, and the outboard sections of both the left horizontal stabilizer and left elevator were bent in a positive direction.

The propeller remained attached to the engine, and both blades exhibited chordwise scratching. In addition, one blade displayed leading edge gouging, and the other blade exhibited tip tearing and blade curling.

The engine remained attached to the airframe and was removed to facilitate further examination. The top cowling was removed, and several pine needles were noted on top of the cylinders, consistent in appearance with those found on the pine tree at the beginning of the wreckage path. The bottom section of the cowling was crushed upward by impact. Engine crankshaft continuity was confirmed from the propeller flange to the accessory section of the engine. All cylinders remained attached to the crankcase, and thumb compression and suction were observed on all cylinders when the crankshaft was rotated by hand. The rocker box covers were removed, and no anomalies were noted with the valve springs and rocker arms. Valve train continuity was confirmed when the crankshaft was rotated through 360°. The throttle and mixture control cables remained attached to the controls in the cockpit but were cut to facilitate examination. Fuel was noted throughout the entire fuel system.

The North Carolina Department of Health and Human Services, Office of the Chief Medical Examiner, Raleigh, North Carolina, performed the autopsy on the pilot. The autopsy report indicated that the pilot's cause of death was multiple blunt force injuries.

The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicological testing of the pilot. Fluid and tissue specimens from the pilot tested negative for carbon monoxide and ethanol. Desmethylsildenafil, sildenafil, and valsartan were detected in the blood and urine. These medications are non-impairing.
