Contributing factors were the high density altitude, the pilot's improper decision to secure the left engine, and his attempt to perform a single-engine go-around. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, go-around (vfr) - emergency procedure - simulated, pilot in command - weather condition - high density altitude (contributing factor) - engine shutdown - intentional, pilot in command (contributing factor) - go-around - attempted, pilot in command (contributing factor) - in-flight planning/decision - improper, pilot in command (contributing factor) - airspeed(vmc) - not maintained, pilot in command (cause) - In flight collision with object, descent - uncontrolled - object - tree(s) - object - residence ## Analysis The 1,000-hour pilot failed to maintain airspeed and lost control of the airplane while attempting to perform a simulated single-engine go-around in a twin-engine airplane. A witness near the approach end of the runway reported observing the airplane moving back and forth in a crab position across the inbound runway course, with the left propeller in the feathered position. A second witness, flying in the traffic pattern behind the accident airplane, reported hearing the pilot report that "he was on a single-engine approach to 14, with a simulated engine out." The witness further stated that as the accident airplane was approximately 20 feet above the middle of the runway, he heard the pilot call out "I'm going around." It was noted by the witness that there was no apparent stress in the tone of the communication, and sufficient distance remained on the runway to land. No emergency transmissions were received from the pilot of the accident airplane. The flaps were found to be in the retracted position at the time of the accident. Examination of the engine and airframe revealed no mechanical anomalies. Examination of the left propeller revealed that the remaining portion of the blade roots and piston were in the feathered position. The governor control lever for the left engine was also found to be in the feathered position. The density altitude was estimated at 2,650 feet. ## Factual narrative HISTORY OF FLIGHT On June 9, 2005, at 1541 central daylight time, a twin-engine Beech 76 airplane, N819ER, was destroyed when it impacted a house in a residential area following a loss of control while attempting a simulated single-engine go-around at the Lone Star Executive Airport (CXO), near Conroe, Texas. The commercial pilot, sole occupant of the airplane, was fatally injured. The airplane was registered to Twin Duchess Corporation of Houston, Texas, and operated by MVP Aero Academy, Inc., of Montgomery, Texas. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight originated from CXO approximately 1450. A witness reported to the NTSB investigator-in-charge (IIC) that as he was driving north along the airport perimeter road near the approach end of Runway 14, when he observed the airplane moving back and forth in a crab position across the inbound runway course, and noted that the "left propeller appeared to be in a feathered or shutdown position." Another witness who was landing his airplane behind the accident airplane reported to the IIC that he heard the pilot report on the local area common traffic advisory frequency (CTAF) that "he was on a single-engine approach to 14, with a simulated engine-out." The witness stated that it was difficult to understand the pilot's radio transmission because of his foreign accent. The witness further stated that as the accident airplane was approximately 20 feet above the middle of the runway, he heard the pilot call out, "I'm going around." There was no apparent stress in the tone of the communication. The next time that the witness saw the accident airplane was when it was coming up from out of the tree line southeast of the runway in a left turn at about 250 feet above ground level (agl), with the "right wing between 70-degrees and vertical." No emergency transmissions were reported. The pilot then saw smoke coming from the area of the impact. PERSONNEL INFORMATION The 32-year old pilot held a commercial pilot certificate with airplane single-engine land, airplane multi-engine land, and instrument airplane ratings. The pilot also held a flight instructor certificate (CFI) with airplane single-engine land, airplane multi-engine land, and instrument airplane ratings. The CFI rating for airplane multi-engine land was issued on February 12, 2005. The pilot was issued a second-class medical on January 22, 2004, without limitations. On March 15, 2005, the pilot reported to MVP Aero Academy that his total flight time was 1,000 hours total flight time, of which 100 hours were in a multi-engine airplane. The academy also recorded that the pilot had given 27 hours of single-engine instruction since March 1, 2005. AIRCRAFT INFORMATION The 1979-model airplane, serial number ME-199, was a low wing, semimonocoque design twin-engine airplane, configured for a maximum of four occupants with a retractable landing gear. The airplane was powered by two Lycoming engines, an O-360-A1G6D (serial number L-32119-36A) and a LO-360-A1G6D (serial number L-552-71A), both rated at 180 horsepower, driving a two-bladed constant speed Hartzell propeller. According to the airframe and engine logbooks, the airplane's most recent 100-hour/annual inspection was on April 2, 2005, with an airframe total time of 12,684.3 hours. The O-360-A1G6D (serial number L-32119-36A) and LO-360-A1G6D (serial number L-552-71A) engines were overhauled on May 4, 2005, and installed on the airframe on May 10, 2005, at an airframe total time of 12,718.6 hours. An examination of the maintenance records for the airplane did not revealed any unresolved maintenance discrepancies prior to its last flight. A fuel receipt from Holley's Jet Center, a local airport fixed base operator, on June 9, 2005, indicated that 26.9 gallons of 100-low lead aviation fuel was purchased to top off the airplane's two 50-gallon tanks. A fuel sample was taken by airport personnel on June 9, 2005, approximately 1630, and no anomalies were noted. METEOROLOGICAL INFORMATION At 1553, the automated surface observing system at CXO reported wind from 150 degrees at 19 knots, visibility 10 statute miles, few clouds at 4,600 feet, temperature 34 degrees Celsius, dew point 21 degrees Celsius, barometric pressure at 29.82 inches of Mercury, with lightning in the distant north. The investigator in charge calculated the density altitude at 2,650 feet. AERODROME INFORMATION The Lone Star Executive Airport (CXO) is an uncontrolled airport. The field elevation is 245 feet mean sea level (msl), and is equipped with an automated surface observing system, a lighted wind indicator, and pilot controlled runway lighting on the common traffic advisory frequency during uncontrolled hours. The common traffic advisory frequency (CTAF) is 122.95 megahertz. The airport features two asphalt runways. Runway 14/32 is 6,000 feet long by 150 feet wide. Runway 1/19 is 3,974 feet long by 100 feet wide. WRECKAGE AND IMPACT INFORMATION The main wreckage was located beside a residential house, approximately 1.2 miles southeast of CXO. The Global Positioning System (GPS) coordinates recorded at the accident site using a hand held GPS unit were latitude 30 degrees 20.23 minutes North and longitude 095 degrees 23.52 minutes West, at an elevation of approximately 218 feet msl. The airplane impacted terrain on a magnetic heading of 315 degrees, and came to rest upright on a measured heading of 340 degrees. The wreckage energy path measured approximately 45 feet in length. An on-scene examination revealed that the airplane struck the top of a tree approximately 35-40 feet in height, before impacting a residence. The residence and the airplane were destroyed by a post-impact fire, but no ground injuries were reported. The cabin area including avionics, fuselage, left wing, right wing, horizontal stabilizer, elevator, vertical stabilizer, and rudder were destroyed by the fire. The remains of all flight control cables were found at the accident site. The left engine remained attached to its mounts and firewall, but was mostly buried under debris from the burned house. The propeller was found separated from the engine, with the flange portion of the crankshaft attached to the propeller hub. Both blades were about 85 percent consumed by fire. The right engine remained attached to its mounts and firewall, but was burned away from the remainder of the nacelle. The propeller was found attached to the engine, with the outboard sections of both blades destroyed by fire. The right side of the engine was not visible at the accident site due to debris from the burned house. On June 12, 2005, the wreckage was recovered to Air Salvage of Dallas (ASOD), near Lancaster, Texas, for further examination. FIRE A post-impact fire consumed the airplane and the residence. MEDICAL AND PATHOLIGCAL INFORMATION An autopsy was performed on June 10, 2005, by a forensic pathologist at the request of the Justice of the Peace, Montgomery County, Texas, in the Southwest Texas Forensic Center in Conroe, Texas. A toxicological laboratory report was also conducted for the Conroe Forensic Center. Toxicological testing on the pilot was performed by the FAA's Civil Aeromedical Institute (CAMI) Forensic and Accident Research Center, Oklahoma City, Oklahoma, for carbon monoxide, cyanide, volatiles, and drugs. TESTS AND RESEARCH Examination of the engines and propellers was conducted on June 13, 2005, at ASOD by representatives of Lycoming Engines, Raytheon Aircraft, and Hartzell Propellers, under the supervision of the NTSB's IIC. Examination of the left engine revealed that the #2 and #4 cylinder heads were burned away. The oil sump was burned away. Most of the accessory housing and accessories were consumed by fire.
