Factual narrative
HISTORY OF FLIGHT
On December 22, 2006, about 2136 eastern standard time, a Beech A36, N3704B, piloted by an instrument rated private pilot, was destroyed on impact with trees and terrain while being vectored on a missed approach north of the Lovell Field Airport (CHA), near Chattanooga, Tennessee. The personal flight was operated under 14 Code of Federal Regulations Part 91. An instrument flight plan was on file and was activated. Night visual meteorological conditions (VMC) prevailed at the time of the accident. The pilot and three passengers sustained fatal injuries. The flight originated from the Gainesville Regional Airport (GNV), near Gainesville, Florida, about 1850 and was destined for CHA.

A witness, who lived about a quarter of a mile from the accident site, stated: At about 9:30 pm I was in my bedroom and I heard an airplane engine rev up real high. I then heard sounds of impacts in the trees behind my house. I then heard my neighbor ... yell that there was a plane down. According to Hamilton County Sheriff's personnel, the airplane wreckage was located about 2145 in a wooded area behind residences about eight nautical miles northeast of CHA by first responders.
PERSONNEL INFORMATION
The pilot held a private pilot certificate for single-engine land airplanes. He received an instrument rating on September 7, 2005. His logbook showed that he had accumulated 54.1 hours of simulated instrument flight time and 2.8 hours of actual instrument flight time at the time he received the instrument rating. The pilot's most recent application for a FAA third-class medical certificate was dated December 14, 2004. He reported that he had accumulated 225 hours of total flight time on the application for that medical certificate. He was issued that medical certificate with no limitations. The last completed page in the pilot's logbook showed that he had accumulated 366 hours of total flight time. That page showed that he had accumulated 29.1 hours of night flight time, 54.1 hours of simulated instrument flight time, and 14.3 hours of actual instrument flight time. He logged 3.9 hours of actual instrument flight time and four instrument approaches in the six month time period prior to the accident and he logged 5.6 hours of actual instrument flight time and three instrument approaches in the six months prior to that time period. The pilot's logbook did not contain an instrument competency check.
AIRCRAFT INFORMATION
N3704B, a 1980-model Beech A36, serial number E-1753, was a low wing, single-engine, six-place airplane, which had retractable tricycle landing gear. The airplane was equipped with a fuel-injected, air-cooled six-cylinder, horizontally-opposed Continental IO-550-BB (15) engine, serial number 573417, which was rated at 285 horsepower. A Hartzell, 3-bladed, all-metal, constant-speed propeller was installed. The airplane was equipped with an autopilot. According to the aircraft's maintenance records, the last recorded annual inspection was dated June 4, 2006. The airplane had accumulated 3,687.5 hours of total time as of that inspection and the tachometer read 2,962.9 hours. The airplane's last altimeter and transponder inspection was completed on March 3, 2005. An invoice and receipt showed that the airplane was serviced at GNV with 46.7 gallons of aviation gasoline (avgas) on December 22, 2006, at 1659.
METEOROLOGICAL INFORMATION
At 2053, the recorded weather at CHA was: Wind 190 degrees at 3 knots; visibility 10 statute miles; sky condition overcast 2,000 feet above ground level (AGL); temperature 15 degrees C; dew point 14 degrees C; altimeter 29.95 inches of mercury. At 2125, the recorded weather at CHA was: Wind 210 degrees at 6 knots; visibility 9 statute miles; sky condition few clouds 500 feet AGL, overcast 1,800 feet AGL; temperature 16 degrees C; dew point 14 degrees C; altimeter 29.95 inches of mercury; remarks drizzle began at 2109 and ended at 2120.
AIDS TO NAVIGATION
CHA was served by an instrument landing system (ILS) approach procedure for runway 20. The ILS approach provided both lateral and vertical guidance for alignment for landing. The inbound magnetic heading for the precision approach procedure was published as 199 degrees. The approach procedure's inbound altitude to the DAISY non-directional beacon was published as 3,000 feet above mean sea level (MSL) or 2,500 feet MSL when authorized by air traffic control. The instrument procedure listed a straight in decision height altitude of 873 feet MSL. Runway 20 was equipped with an approach lighting system with sequenced flashing lights. The missed approach procedure was listed as; "Climb to 1300 then climbing left turn to 3100 direct GQO VORTAC and hold."
AIRPORT INFORMATION
The airport elevation at CHA was 683 feet above mean sea level (MSL). CHA was a controlled airport with two runways, 2/20 and 15/33. Runway 2/20 was 7,400 feet long and 150 feet wide. That runway's surface was composed of asphalt. A precision approach path indicator (PAPI) served runway 33 for visual approach guidance. Runway 2 and 15 were served by a vertical approach slope indicator (VASI). Runway 20 did not have a VASI or PAPI.
WRECKAGE AND IMPACT INFORMATION
The wreckage was found about 20 degrees and eight nautical miles from the approach end of runway 20. The airplane's wings and fuselage were found fragmented in the wooded area on about a 307 degree magnetic heading in a debris pattern that was about 305 feet long. The separated sections of the wings were found starting at the southeast beginning of the debris field to about the middle of the debris. The propeller was found, separated from the engine, resting about the middle of the debris field. The empennage and fuselage were found in the middle of the debris field. The engine was separated from the fuselage and was found at the northwest end of the debris field. An on-scene investigation was conducted. The flight control cables were traced from the cockpit flight controls to their respective flight controls. All flight control breaks were consistent with overload. The engine controls were traced from the cockpit to the engine and all separations in the cables were consistent with overload. A liquid consistent with avgas was found in the fuel tank selector valve. The selector was positioned to the right tank. A liquid consistent with avgas was found in the fuel manifold valve. The left magneto sparked at all leads when the engine was rotated by hand. The right magneto separated from the engine and it produced spark at four of its six leads when rotated by hand. The two leads that did not exhibit spark sustained impact damage. The removed spark plugs exhibited no pre-impact anomalies. The engine produced a thumb compression at the rear four cylinders. The front two cylinders sustained impact damage. Observations of their valve and piston movements were consistent with normal operations. The left flap jackscrew extension was consistent with retracted flaps. The landing gear linkage position was consistent with retracted landing gear. The flap and landing gear selector switches were in the up position. The tachometer read 2,995.48 hours. No airframe or engine pre-impact anomalies were detected.
MEDICAL AND PATHOLOGICAL INFORMATION
An autopsy was performed on the pilot by the Hamilton County Medical Examiner's Office. The FAA Civil Aeromedical Institute prepared a Final Forensic Toxicology Accident Report. The report was negative for the tests performed.
TESTS AND RESEARCH
Continuous Data Recording (CDR), which is airplane radar track data, was obtained from the FAA and was plotted. That plotted data showed that the airplane descended below altitudes the air traffic controller vectored the airplane on and below published altitudes for the precision approach. The data showed that the airplane did an undirected 360-degree turn while being vectored and another undirected turn near the accident site.
ADDITIONAL INFORMATION
Federal Aviation Regulations, Part 61.57 Recent flight experience, pilot-in-command, in part, stated: (c) Instrument experience. Except as provided in paragraph (e) of this section, no person may act as pilot in command under IFR or in weather conditions less than the minimums prescribed for VFR, unless within the preceding 6 calendar months, that person has: (1) For the purpose of obtaining instrument experience in an aircraft (other than a glider), performed and logged under actual or simulated instrument conditions, either in flight in the appropriate category of aircraft for the instrument privileges sought or in a flight simulator or flight training device that is representative of the aircraft category for the instrument privileges sought - (i) At least six instrument approaches; (ii) Holding procedures; and (iii) Intercepting and tracking courses through the use of navigation systems. ... (d) Instrument proficiency check. Except as provided in paragraph (e) of this section, a person who does not meet the instrument experience requirements of paragraph (c) of this section within the prescribed time, or within 6 calendar months after the prescribed time, may not serve as pilot in command under IFR or in weather conditions less than the minimums prescribed for VFR until that person passes an instrument proficiency check consisting of a representative number of tasks required by the instrument rating practical test. The parties to the investigation included the FAA and Raytheon Aircraft Company. The aircraft wreckage was released to a representative of the insurance company. The airplane, piloted by an instrument rated private pilot, was destroyed on impact with trees and terrain while being vectored on a missed approach. An instrument flight plan was on file and was activated. Night visual meteorological conditions prevailed at the destination airport at the time of the accident. However, instrument conditions were reported at approach altitudes. In a transmission with the air traffic controller during the flight, the pilot stated he was "disorientated" and he confirmed that the "trouble" was not with the airplane. Plotted radar data showed that the airplane descended below altitudes the airplane was being vectored on and below published altitudes for the precision approach. The air traffic controller cancelled the approach clearance and gave a missed approach clearance to climb. The data showed that the airplane did an undirected 360-degree turn while being vectored and another undirected turn near the accident site. The pilot had accumulated 366 hours of total flight time. He had accumulated 29.1 hours of night flight time, 54.1 hours of simulated instrument flight time, and 14.3 hours of actual instrument flight time. He logged 3.9 hours of actual instrument flight time and four instrument approaches in the six months prior to the accident. The pilot's logbook did not contain an instrument competency check. The recorded weather at the destination was: Wind 210 degrees at 6 knots; visibility 9 statute miles; sky condition few clouds 500 feet, overcast 1,800 feet; temperature 16 degrees C; dew point 14 degrees C; altimeter 29.95 inches of mercury; remarks drizzle began about 27 minutes before the accident and ended about 16 minutes before the accident. An on-scene investigation was conducted and no airframe or engine pre-impact anomalies were detected. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
