NTSB Factual Report

HISTORY OF FLIGHT

On September 7, 2016, at 1048 eastern daylight time, a Beech F33A, N6027K, and a Diamond Aircraft Industries DA20-C1, N85WP, collided in midair on the final approach leg of the traffic pattern to runway 35 at West Georgia Regional Airport (CTJ), Carrollton, Georgia. The Beech was substantially damaged, and the private pilot was fatally injured. The Diamond was destroyed, and the flight instructor and the student pilot were fatally injured. The Beech was registered to and operated by the private pilot. The Diamond was registered to and operated by Falcon Aviation Academy LLC. Both flights were conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 91; the Beech pilot was conducting a personal flight, and the Diamond pilots were conducting an instructional flight. Visual meteorological conditions prevailed, and no flight plans were filed for either flight. The Beech departed from Fulton County Airport (FTY), Atlanta, Georgia, about 0915, and the Diamond departed from Newnan Coweta County Airport (CCO), Newnan, Georgia, about 1000.

According to personnel from Falcon Aviation Academy, the pilots of the Diamond were practicing traffic pattern operations and landings at CTJ. The Diamond entered the traffic pattern, followed a few minutes later by N263CF and then by N169PS, both Falcon Aviation Academy DA20s. The flight instructor and student pilot on board N263CF saw the Beech on the downwind leg of the traffic pattern. Moments later, the flight instructor and student pilot on board N169PS entered the traffic pattern from the east. They looked down and to the left, in the direction of the final approach path for runway 35, and saw two airplanes collide. The instructors and the students on board both trailing DA20s reported that they did not hear the Beech pilot broadcasting his intentions on the CTJ common traffic advisory frequency (CTAF) but they heard the accident Diamond making position calls in the traffic pattern before the collision, with the last call being made on the final approach.

Another flight instructor employed by Falcon Aviation Academy reported that he was familiar with the Beech pilot and his airplane. He had just completed a flight at CCO and heard the Beech pilot broadcasting traffic pattern calls for CTJ about the time of the accident; however, the Beech pilot was broadcasting over the CCO CTAF of 122.7 MHz. The flight instructor reported that the Beech pilot was not in the traffic pattern at CCO at the time of the transmissions.

Radar data provided by Federal Aviation Administration (FAA) air traffic control personnel indicated that the Beech pilot entered an extended left downwind for CTJ from the north, above and behind the accident Diamond, which was on the downwind leg of the traffic pattern. The ground speed of the Beech was about 50 knots greater than the ground speed of the Diamond. The last radar returns were on the downwind leg, about 2,000 ft above mean sea level, or about 850 ft above the ground. The locations of the last radar returns showed the airplanes approaching the base leg for runway 35.

The Diamond was not equipped with GPS data recording capability. A portable GPS receiver recovered from the Beech recorded the accident flight. The recording indicated that the Beech was established on the downwind leg for runway 35, about 2,500 ft GPS altitude and 150 knots groundspeed. The CTJ airport elevation was 1,164 ft. The Beech descended toward the base leg, turning base about 2,200 ft and 122 knots. The Beech turned onto final about 1,450 ft and 79 knots. The last recorded data point was at 1048:00, with the Beech at 1,201 ft and 76 knots, about 607 ft south of the runway 35 threshold.

The published traffic pattern direction for runway 35 was to the left. Falcon Aviation Academy personnel reported that their pilots frequently used CTJ for training purposes.

The CTAF/UNICOM frequency for CTJ at the time of the accident was 122.975 MHz. CTAF communications were not recorded. The airport manager reported that the CTJ CTAF frequency was changed from 122.7 MHz to 122.975 MHz in 2011.

WRECKAGE AND IMPACT INFORMATION

General

The main wreckage of both airplanes came to rest in a grass field, about 408 ft south of the approach end of runway 35, on the extended centerline of the runway. The Diamond came to rest in an upright position. The Beech came to rest inverted and on top of the Diamond wreckage. The wreckage debris field was about 350 ft long and about 80 ft wide, oriented on a heading of 350º. All major structural components of both airplanes were accounted for within the wreckage debris field.

Beech

The wreckage of the Beech was generally intact; the wings and empennage remained attached to the fuselage. Flight control cable continuity was established from the cockpit controls to the flight control surfaces. The ailerons, elevator, and rudder remained attached in their respective positions on the wings, horizontal stabilizer, and rudder. Blue-colored paint transfer marks were found on the lower surface of the right wing, near wing station 108. Impact damage with paint transfer was found on the top of the fuselage around station 131.

The nose gear separated from the airplane during the impact sequence. White paint transfer markings were observed on the nose gear tire. The left and right main landing gear were found in the extended positions. White paint transfer markings were observed on the left, main gear tire. The wing flaps were extended 20º.

The master and avionics switches were found in the "on" positions. The strobe light switch was found in the "on" position. The taxi light switch was found in the "on" position, and the landing light was found in the "off" position; however, both switches had impact damage. The position of the navigation light switch could not be determined because of impact damage.

The engine remained attached to the firewall. External examination of the engine did not reveal physical evidence of a mechanical malfunction or anomaly. The propeller assembly separated from the engine at the crankshaft/propeller flange junction. The fracture surfaces exhibited features consistent with overload. The propeller blades remained attached to the hub and displayed chordwise scratches, blade twisting, leading edge gouging, and surface polishing.

A laminated card titled "LOCAL AREA FREQ" and dated April 27, 2009, was found in the Beech's cockpit. The card, which listed the frequencies for multiple airports in the area, listed the frequency for the CTAF at CTJ as 122.7 MHz.

Diamond

The Diamond came to rest upright, under the wreckage of the Beech. Flight control continuity was confirmed from the elevator and rudder to the cockpit controls. Aileron control continuity was confirmed from the right aileron to the cockpit controls. The left wing separated from the fuselage during the impact sequence. The left aileron control tubes had multiple fractures that exhibited overload signatures. The empennage separated from the fuselage about 14 inches forward of the vertical stabilizer root leading edge.

Blue paint transfer marks were observed on the leading edge of the Diamond's right wing. The marks were about 8 inches long and 12 inches from the wing root. The Diamond's landing, taxi, strobe, and position light switches were impact-damaged, and their preimpact positions could not be determined.

Lightweight pieces of the Diamond were found on a northerly path, beginning 340 ft south of the main wreckage. One of the most southerly pieces of wreckage debris was the right half of the Diamond's elevator. Closer examination revealed black transfer markings on the upper surface of the elevator that were consistent in color and tread pattern with the right main landing gear tire of the Beech. Examination of the Diamond's horizontal stabilizer revealed similar transfer markings on its upper surface. The other small pieces of debris located south of the main wreckage were identified as sections of the Diamond's canopy and wing root/fuselage skin.

MEDICAL AND PATHOLOGICAL INFORMATION

The Beech Pilot

The Georgia Bureau of Investigation Division of Forensic Sciences performed an autopsy of the Beech pilot and the cause of death was blunt trauma of the head and chest, and the manner of death was accident.

The FAA's Bioaeronautical Research Sciences Laboratory, Oklahoma City, Oklahoma, performed toxicology testing and identified doxazosin and losartan in the pilot's blood, and doxazosin, dextromethorphan, and its metabolite dextrorphan in urine. Doxazosin and losartan are blood pressure medications also named Cardura and Cozaar, respectively. The pilot reported the use of doxazosin and losartan to the FAA during his most recent FAA third-class physical. Dextromethorphan is an over-the-counter cough suppressant available in a number of products.

The Diamond Flight Instructor

The Georgia Bureau of Investigation Division of Forensic Sciences performed an autopsy of the Diamond flight instructor and the cause of death was blunt head trauma, and the manner of death was accident.

The FAA's Bioaeronautical Research Sciences Laboratory, Oklahoma City, Oklahoma, performed toxicology testing of the flight instructor. The specimens tested negative for carbon monoxide, ethanol, and a wide range of drugs, including major drugs of abuse.

The Diamond Student Pilot

The Georgia Bureau of Investigation Division of Forensic Sciences performed an autopsy of the Diamond student pilot and the cause of death was blunt trauma of the head and torso, and the manner of death was accident.

The FAA's Bioaeronautical Research Sciences Laboratory, Oklahoma City, Oklahoma, performed toxicology testing of the student pilot. The specimens tested negative for carbon monoxide, ethanol, and a wide range of drugs, including major drugs of abuse.

TESTS AND RESEARCH

The King KX 155 VHF transceiver and the Garmin GNS 530 all-in-one unit from the Beech were sent to the NTSB Vehicle Recorders Laboratory to determine the frequencies in use at the time of the accident. The examination revealed that the KX 155 communication frequencies were set to 118.17 MHz (active) and 126.22 MHz (standby). The GNS 530 communication frequencies were set to 122.7 MHz (active) and 124.050 MHz (standby). The waypoint communications information page for CTJ was accessed during the examination even though the installed GNS 530 aviation database expired as of November 12, 2015. The CTAF/UNICOM on the displayed page showed the correct frequency of 122.975 MHz.

ADDITIONAL INFORMATION

FAA Rules, Regulations, and Guidance to Pilots

Title 14 CFR 91.113 addresses aircraft right-of-way rules and states, in part, the following:

(b) General. When weather conditions permit, regardless of whether an operation is conducted under instrument flight rules or visual flight rules, vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft. When a rule of this section gives another aircraft the right-of-way, the pilot shall give way to that aircraft and may not pass over, under, or ahead of it unless well clear.

(f) Overtaking. Each aircraft that is being overtaken has the right-of-way and each pilot of an overtaking aircraft shall alter course to the right to pass well clear.

(g) Landing. Aircraft, while on final approach to land or while landing, have the right-of-way over other aircraft in flight or operating on the surface, except that they shall not take advantage of this rule to force an aircraft off the runway surface which has already landed and is attempting to make way for an aircraft on final approach. When two or more aircraft are approaching an airport to landing, the aircraft at the lower altitude has the right-of-way, but it shall not take advantage of this rule to cut in front of another which is on final approach to land or to overtake that aircraft.

The FAA's Aeronautical Information Manual (AIM), dated December 10, 2015, paragraph 5-5-8, includes pilot procedures for see-and-avoid while in flight and states, "When meteorological conditions permit, regardless of type of flight plan or whether or not under

NTSB Probable Cause

The failure of the Beech pilot to see and avoid the Diamond that was in front of and below his airplane on final approach and his use of an incorrect radio communication frequency for the airport.
