HISTORY OF FLIGHT

On March 31, 2002, at 1153 eastern standard time, a Piper PA-34-200T, N2BX, registered to and co-owned by the pilot, experienced an in-flight break-up following maneuvers, and a rapid descent in Apex, North Carolina. The personal flight was operated by the private pilot under the provisions of Title 14 CFR Part 91, and instrument flight rules (IFR). Instrument meteorological conditions prevailed and an IFR flight plan was filed for the personnel flight to Raleigh-Durham International Airport. The pilot and passenger received fatal injuries, and the airplane was destroyed. The flight originated at Malcolm McKinnon Airport in Brunswick, Georgia, at 1000 on March 31, 2002.

A review of radar data and recorded voice communications and transcripts between the pilot and Raleigh-Durham (RDU) Air Traffic Controllers (ATC) found that at 1142:50, N2BX was approximately 30 miles south southwest of RDU north departure radar (N-DR) controller and advised he was inbound to the airport at 9,000 feet with information "Romeo." The N-DR controller advised the pilot to expect the ILS runway 5R approach. The pilot read back 5L and the N-DR controller corrected him to expect 5R. At 1145:29 N2BX was approximately 22 miles south southwest of the airport at a ground speed of 186 knots when the N-DR controller instructed the pilot to descend and maintain 4,000 feet and turn 10 degrees to the left. N2BX's Mode C indicated 9,100. At 1146:58 the N-DR controller instructed the pilot to fly heading 320 degrees Mode C indicated 8,000 feet at a ground speed of 203 knots. The pilot acknowledged both transmissions.

At 1148:49, N2BX was approximately 13 miles southwest of RDU and the N-DR controller advised, "are you gonna make the descent I'm turning you into the final in about 3 to 4 miles." N2BX's Mode C indicated 7,100 feet at a speed of 164 knots. The pilot acknowledged that he would expedite his descent. At 1149:39, N2BX was approximately 12 miles southwest of RDU when the N-DR controller advised the pilot, "4 miles from the final approach fix turn right heading 010 maintain at or above 2,400 till established on the localizer clear ILS runway 5R approach." SPUNK is the final approach fix for the procedure and is located approximately 7 miles southwest of the airport. The approach extends from the airport southwest with an inbound course along a 052-degree bearing. Mode C indicated 5,400 feet at a speed of 191 knots. At 1150:24, the N-DR controller observed N2BX going through the localizer and instructed the pilot to turn left heading 090 degrees to rejoin. The pilot acknowledged the transmission. N2BX's Mode C indicated 4,100 feet at a speed of 211 knots. At 1150:29, radar data was no longer providing Mode C readout. At 1150:47, the data block indicated the track entered "coast" status and could no longer associate the flight plan information with the radar returns. At 1150:55, the N-DR controller requested the pilot state his altitude. The pilot did not respond. The N-DR controller made several more attempts to contact N2BX. No further communications were received. Search and rescue notifications were initiated.

Witnesses in the area reported hearing airplane engine noises, then seeing the airplane come out of the fog straight down, with one wing coming down separately and debris continuing to fall afterwards.

PERSONNEL INFORMATION

A review of information on file with the Federal Aviation Administration (FAA) Airman's Certification Division, Oklahoma City, Oklahoma, revealed the pilot was issued a private pilot certificate on June 19, 1993, with rating for airplane single engine land, multiengine land, and instrument airplane. A review of the pilot's logbook revealed his last recorded biennial flight review was conducted on November 21, 2000. The logbook also revealed that the pilot had accumulated a total time of 619 hours with 206 in single engine airplanes and 410 in multiengine airplanes. A review of records on file with the FAA Aeromedical Certification Division revealed the pilot held a third class medical certificate issued on October 23, 2001.

Examination of the left wing, aileron and flap were found that the wing was cut near the wing root for aircraft recovery. The wing was separated approximately 7 feet from the wing root. The bottom spar separation area was bent upward approximately 45-degrees. The matting surface for the top spar, approximately 6 inches, was not found. This spar section was located behind the inboard fuel tank area, and this section of the wing measured 6 feet in length. The top spar separation area on the 6-foot section of the wing displayed tension and was bent upward, and 9 inches outboard. The top spar was bent downward approximately 45-degrees. The skin section on the top spar displayed buckling. The bottom section of the spar in the same location was broken.

The left fuel cap was not in-place. The left aileron was separated from its attachment points. The aileron was bent in a "V" like shape. The balance weight was attached. The aileron cables were attached to the bell crank and separated near the mid wing area. The cable separation was unwound. The aileron stops were in-place and intact. A section of the left main spar was sent to the NTSB's metallurgical laboratory in Washington, DC for further examination.

Examination of the right wing found the wing, flap and aileron impact damaged. The wing was separated at the wing root. The main landing gear was found in the down and locked position. The upper main spar cap at the wing root separation displayed compression damage, and the bottom spar cap separation displayed tension damage. Outboard of the right engine nacelle, the wing was also separated. This section of the spar displayed upward bending.

The fuel pump rotated freely when turned by hand. The number six fuel injection line and fuel supply line were broken at the valve. The valve was separated and contained clean fuel. Crankshaft continuity was established through the gear train, cylinder movement and push rod movement by rotating the propeller 90-degrees. The vacuum pump was intact; the vanes were intact, and turned freely when rotated by hand. Other then impact damage, no discrepancies were found that would have prevented the engine from operating normally.
