During previous flights, the right engine lost boost then overboosted intermittently, and attempted repairs were unsuccessful. The pilot elected to fly the airplane to its home base for further troubleshooting. During cruise flight, the pilot reported an engine was surging, declared an emergency, and received vectors toward the airport. The airplane collided into a field beside the airport runway and caught fire. The airplane had a total of 8 to 10 hours of flight time at the time of the accident. Records revealed that two days after the airplane's first test flight, the pilot flew the airplane from Melbourne, Florida, to an airport 336 nm miles away, then flew it to Canada to display it at a fly-in.The FAA operating limitations for the airplane restricted its operation to flight test only, which was proposed to consist of 100 flight hours, since the installation of the modified engines. No single-engine performance data was available for this airplane. Examination of the engines and accessories revealed extensive fire and impact damage. Continuity of the crankshaft, valves, rods, and pistons was established for the right engine by manually rotating the propeller reduction control unit. ## Factual narrative HISTORY OF FLIGHT On October 23, 2002, at 2128 eastern daylight time, an experimental Beechcraft A60, N73CR, registered to Duke Aircraft Corporation and operated by the pilot, collided with the ground and caught fire during an emergency landing at the Jesup Wayne County Airport in Jesup, Georgia. The personal flight was operated under the provisions of Title 14 CFR Part 91 with an instrument flight rules plan filed. Visual meteorological conditions prevailed. The Canadian-certificated airline transport pilot and the private pilot-rated passenger received fatal injuries, and the airplane was destroyed. The flight departed Delaware County Johnson Field in Muncie, Indiana, at 1832 on October 23, 2002. A review of flight service station records revealed the pilot obtained a weather briefing and filed an instrument flight rules plan for a flight from Muncie, Indiana, direct to Melbourne, Florida. At 1832:54, the pilot contacted Muncie Air Traffic Control and reported climbing from the airport. During cruise flight at 12,000 feet mean sea level over Reidsville, Georgia, the pilot contacted Jackson Air Route Traffic Control Center at 2109:05 and stated he wanted to land because of "difficulties with an engine." The controller stated to the pilot he had just passed over the Reidsville, Georgia, airport, and the Jesup, Georgia, airport was ahead. The pilot requested and received radar vectors for the Jesup, Georgia, airport, and the controller issued a clearance to descend. At 2115:22, the pilot reported, "We have an engine that's surging," and, at 2115:30, the pilot declared an emergency. A witness in Reidsville, Georgia, stated he heard a strange-sounding airplane flying north to south overhead at 2110. He heard one engine running smoothly, and the other engine sounded like it would repeatedly come up full throttle, then "die down" for four or five seconds, then come up full throttle again. He stated it was not popping or sputtering. At 2120:36, the controller told the pilot he passed the airport, and the controller provided vectors to bring the flight back for the approach. At 2122:52, the controller told the pilot radar contact was lost. At 2123:22, the controller told the pilot to climb back up to the assigned altitude of 2,000 feet mean sea level, and the pilot replied, "We can't get any climb." At 2123:57, the pilot stated, "we have a rotating beacon at twelve o'clock," and, at 2126:07, the pilot stated, "charlie romeo has the field." No further radio transmissions were received from the pilot. Two witnesses within four miles of the airport described airplane engine noises that sounded like "a Gatling gun cutting in and out," "a dragster car starting up," or the sound heard when a car is driven over rumble strips. Local law enforcement and rescue personnel who were dispatched to the airport observed the airplane engulfed in flames in a field beside the runway. PERSONNEL INFORMATION The pilot held a Canadian airline transport certificate for single-engine and multi-engine land airplanes issued on January 9, 2001, and a U.S. special purpose commercial pilot foreign-based certificate for single-engine and multi-engine land airplanes issued on May 20, 1997. Transport Canada Aviation System Safety, Ontario, Canada, reported the pilot held a category 1 medical certificate issued on May 10, 2002, with the notation "glasses or contacts worn." The pilot's logbook was not recovered for examination. A review of flight training records provided by the facilitators of a Beechcraft Duke Recurrent Training course revealed the pilot completed a biennial flight review and instrument competency check on September 25, 2002. The passenger held a private pilot certificate for airplane single-engine land issued on October 5, 1994. He held a third class medical dated September 12, 2002, with a restriction for corrective lenses. AIRCRAFT INFORMATION The experimental airplane was originally certificated as a Beechcraft A60. The factory-installed 380-horsepower engines were removed, and the airplane was equipped with two experimental Engine AIR Power Systems TSIVD-427, 500-horsepower, liquid-cooled, turbocharged, V8 engines with experimental MT Propeller four-bladed wood and composite propellers. The engine mounts were experimental assemblies. The left engine was equipped with a 24-volt alternator and two 12-volt batteries in series that powered the airplane's original 28-volt electrical system. Of the two batteries that comprised the 24-volt system, one battery was used exclusively for the 12-volt electrical system for the left engine power requirements. The right engine was equipped with one 12-volt alternator and one 12-volt battery that powered the 12-volt electrical system independent of the systems powered by the left engine. Each engine was equipped with a full authority digital engine control unit, electric fuel pumps, an electric ignition system, and an electronic fuel injection system that were powered by each engine's respective independent 12-volt system. According to maintenance records, the airframe total time in service at the time of the engine installation was 5104.8 hours. Witnesses in Muncie, Indiana, and an acquaintance of the pilot reported the airplane had accumulated 8 to 10 hours since the experimental engine installation when it departed on the accident flight. METEOROLOGICAL INFORMATION The Savannah International Airport, Automated Surface Observation System, located 49 nautical miles northeast of the accident site, reported at 2053 conditions were winds 030 at 9 knots, visibility 10 statute miles, ceiling overcast 2,000 feet above ground level, temperature 19 degrees Celsius, dew point 17 degrees Celsius, altimeter setting 30.10 inches. WRECKAGE AND IMPACT INFORMATION Examination of the accident site revealed the wreckage was fire-damaged and located in a grassy field on the left side of runway 28. The wreckage was approximately 450 feet from the edge of the runway and 1,200 feet west of the runway 28 threshold. Wreckage debris was scattered along a 67-foot path on a 275-degree magnetic heading from the initial impact ground scar. The initial accident site ground scar contained fragments of green lens from the right wingtip navigation light, and the right wing outboard of the engine nacelle was separated and crushed aft with the fuel tank breached. Burned grass and charred ground extended from the separated wing portion and encircled the wreckage and debris field. The fuselage, empennage, horizontal stabilizer, and elevator were found upright oriented on an approximate 090-degree magnetic heading and were fire damaged. The landing gear transmission assembly was found in a position consistent with gear extension. Melted metal skin and flight control components from the horizontal stabilizer, elevator, and empennage were found aft of the cabin section in positions consistent with their normal locations. The vertical stabilizer with the rudder attached was found amid the horizontal stabilizer and elevator debris. The rudder cables remained attached to the rudder horn, and the elevator cables remained attached to the actuators. Control cable continuity was established from the rudder and elevator to the aft cabin floor. The cabin and instrument panel sustained fire and crush damage. The throttle quadrant was fire damaged and crushed. The left fuel selector valve was fire damaged and in the on position, and the right fuel selector was fire damaged and found in the cross-feed position. The right engine was found separated from the wing and was fire damaged. The right engine was found upright adjacent to the right side of the cabin debris with the forward side facing the cabin. Propeller blade fragments from the right propeller were found embedded in a series of ground scars along the wreckage path, and the charred remains of one propeller blade remained attached to the hub assembly on th ## Aircraft - Registration: [N73CR](https://openairdocs.org/deregistered/N73CR-2017-07-06), registration cancelled 2017-07-06, S/N P-222, built 1973 (OpenAirDocs) - Reported make and model: Beechcraft A60 - Registry model: [Beech A60](https://openairdocs.org/model/beech-a60) (registry code 1153604) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane - Serial number: P-222 - Airframe hours: 5125 - Engines: EngineAIR Power Systems TSA D 427 500 horsepower reciprocating; EngineAIR Power Systems TSIVD-427 500 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Operator: J.
