Colorado Aviation Accidents & Incidents

On June 16, 2024, about 0741 mountain daylight time, a Tecnam P2006T airplane, N968GV, was substantially damaged when it was involved in an accident near Larkspur, Colorado. The flight instructor and pilot receiving instruction were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 instructional flight.
The flight instructor stated that he and the commercial-rated pilot receiving instruction (pilot) were completing a multi-engine training flight, which was their first multi-engine training flight together. The flight instructor had accumulated 115 flight hours in the accident airplane make and model, all of which were completed while acting as flight instructor.
During the first portion of the flight, they completed five full-stop, taxi-back landings at Centennial Airport (APA), Englewood, Colorado. After the final landing, they proceeded to the southwest and climbed to 10,800 ft mean sea level (about 4,500 ft above ground level [agl]), where they intended to practice OEI training procedures in the North Perry practice area designated for multi-engine training. They initially completed directional control exercises and multiple simulated engine-out emergencies so the pilot receiving instruction could understand the step-by-step process. Next, they shut down the left engine by turning the left ignition switches to OFF. With the engine secured and the propeller feathered, the pilot maneuvered the airplane for “a little bit” until they attempted to the restart the engine. They referenced the engine restart checklist and attempted to restart the engine but were unsuccessful. They waited about 5 seconds, then engaged the starter buttons again and the engine restarted successfully. They slowly increased the left engine throttle and completed the cruise checklist before proceeding back toward APA. While en route, the flight instructor noted that the airplane required additional right rudder to maintain control. The pilot took over the controls and confirmed that more right rudder was required. The flight instructor noted that the left engine coolant temperature and rpm had decreased so he took back the controls and proceeded to Perry Park Airport (CO93), Larkspur, Colorado, which was about 4 nm south of their location. After completing a 180° turn to south, he secured the left engine and feathered the propeller. The airplane was difficult to control and the airplane was rapidly losing altitude. When he realized that they could not reach CO93, he set up to land on Interstate 25 (I-25). Just before landing in the southbound lanes of I-25, he pitched up and banked left to avoid hitting southbound vehicles. The airplane climbed over the traffic, then impacted a marshy area to the east of I-25.
The pilot receiving instruction reported that he had previously accumulated 2 flight hours in the accident airplane make and model, which was his only multi-engine flight experience. He added that when they turned t
