One witness indicated the pilot flew the airplane low enough to be identified. The pilot performed a second flyby of the houses. Another witness indicated that the airplane subsequently flew south and then climbed in a counterclockwise rotation. The airplane then attempted to "go upside down" and fly to the west. It subsequently impacted terrain following the low-level acrobatic maneuver. Examination of the wreckage did not reveal any preimpact anomalies. ## Factual narrative N2726C was a Nanchang CJ-6 airplane with serial number 5232007. The airplane was manufactured in 1991. Airworthiness records show that the airplane's amended special airworthiness certificate in the experimental exhibition category and purpose was issued on November 16, 2010. Records also indicated that the airplane was equipped with a M-14P radial engine with serial number KR322012, which drove a model number B530TA propeller. The last yearly condition inspection was conducted on June 17, 2012. A logbook endorsement indicated the airplane had accumulated 2,697.18 hours total time. At the time of that inspection, the engine had accumulated 62.8 hours total time in service. On June 23, 2013, about 0811 mountain daylight time, an experimental exhibition Nanchang China CJ-6 airplane, N2726C, impacted terrain while maneuvering near Wolcott, Colorado. The private pilot and the pilot rated passenger were both fatally injured. The airplane sustained substantial fuselage damage. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Day visual flight rules (VFR) conditions prevailed for the flight, which did not operate on a VFR flight plan. The local flight originated from the Eagle County Regional Airport (EGE), near Eagle, Colorado, about 0757. Witnesses, who lived near the accident site, stated that the pilot flew over their houses. One witness, who was a friend of the pilot, indicated the pilot flew the airplane low enough to be identified as the pilot. The pilot performed a second flyby of the houses. One witness indicated that the airplane subsequently flew south and then climbed in a counter clockwise rotation. The airplane attempted to "go upside down" and fly to the west. The airplane descended below the witness's line of sight. His wife call 911 and he ran to the accident site where he waited for first responders. The Eagle County Coroner's Office arranged for an autopsy to be performed on the pilot. The cause of death was listed as multiple injuries. The FAA Civil Aerospace Medical Institute (CAMI) prepared a Final Forensic Toxicology Accident Report on samples taken from the pilot. The report indicated: Tamsulosin detected in Muscle Tamsulosin detected in Liver The FAA Forensic Toxicology's WebDrugs website description of Tamsulosin, in part, indicated it was an a1a-selective alpha blocker used in the symptomatic treatment of benign prostatic hyperplasia. The Eagle County Coroner's Office arranged for an autopsy to be performed on the pilot rated passenger. The cause of death was listed as multiple injuries. The FAA CAMI prepared a Final Forensic Toxicology Accident Report on samples taken from the pilot rated passenger. The report stated that the samples sustained putrefaction and further indicated: 44 (mg/dL, mg/hg) Ethanol detected in Urine 28 (mg/dL, mg/hg) Ethanol detected in Muscle 25 (mg/dL, mg/hg) Ethanol detected in Brain At 0750, the recordedweather at EGE was: wind calm; visibility 10 statute miles; sky condition clear; temperature 11 degrees C; dew point -4 degrees C; altimeter 30.12 inches of mercury. The pilot, age 70, held a Federal Aviation Administration (FAA) private pilot certificate with a single engine land airplane rating. A FAA third class medical certificate was issued to the pilot on August 30, 2012 with a restriction for near vision lenses. On the application for that medical certificate, he reported accumulating 1,180 hours total flight time with 15 hours accumulated in the previous six months. The pilot reported using Tamsulosin. The pilot recorded in his logbook that he had accumulated 1,200.1 hours of total flight time, 5.4 hours of flight time in the 90 days prior to the accident, 2.6 hours of flight time in the30 days prior to the accident, and 120.1 hours of flight time in the CJ-6. The pilot rated passenger, age 69, held a commercial pilot certificate with single and multi-engine land, and instrument airplane ratings. The passenger did not have a current medical certificate on file in FAA records. The airplane impacted terrain near the intersection of Horse Mountain Ranch Road and Elk Ridge Road. A witness mark on the ground was consistent with the airplane initially impacting terrain and sliding about 100 feet. The airplane became airborne again and came to rest about 162 feet from its first impact point. A FAA inspector examined the wreckage. The inspector indicated that all components, which were possible to examine, had their control continuity confirmed and the airplane was confirmed to have fuel on board when the crash occurred. ## Aircraft - Registration: [N2726C](https://openairdocs.org/deregistered/N2726C-2018-03-01), registration cancelled 2018-03-01, S/N 5232007, built 1991 (OpenAirDocs) - Reported make and model: NANCHANG CHINA CJ-6 - Registry model: [Nanchang China CJ-6](https://openairdocs.org/model/nanchang-china-cj-6) (registry code 05628VC) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane - Serial number: 5232007 - Year built: 1991 - Airframe hours: 2697.18 - Engines: Russia M-14P reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pilot - Registered owner: Pilot - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, June 17, 2012 - Departed: EGE, Eagle, CO - Destination: EGE, Eagle, CO - Flight plan: Unknown ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
