History of Flight
On August 21, 2021, about 0853 central daylight time, an Aeronca 7AC airplane, N1472E, sustained substantial damage when it was involved in an accident near Fort Worth, Texas. The airline transport pilot and the passenger sustained fatal injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot was going to conduct a local flight with his son. The pilot was seated in the rear seat, and the passenger was seated in the front seat.
Multiple witnesses saw the airplane take off from runway 15. One witness, a flight instructor, reported that during the initial takeoff roll, the airplane became “out of control” and “almost ground looped.” He described the subsequent takeoff roll as “extra-long” and stated that the airplane “appeared to get slow” during the initial climb. He reported that the airplane started a “roll to the right,” the left wing “fell,” and the airplane stalled and entered a spin about 100 ft above ground level (agl).
A second witness reported that during the takeoff, the airplane appeared to be “barely climbing.” Near the end of the runway, about 100 ft agl, he observed a “strong right yaw” followed by a gradual left turn. The pilot appeared to lower the nose, then the airplane “rolled hard left,” and entered a spin.
The witnesses did not recall hearing any abnormal noises originating from the engine.
Personnel Information
According to Federal Aviation Administration (FAA) records, the pilot held several type ratings. His personal flight logs were not available for review, and his experience in the accident airplane was not determined.
Aircraft Information
The pilot purchased the airplane in May 2021. Utilizing the airplane’s weight and balance records and the weights of the two occupants, weight and balance values were calculated for the accident flight. With a full fuel and oil load with no baggage onboard, at the time of departure, the airplane was 225.6 lbs over the maximum gross weight while the center of gravity was within limitations.
An examination of the airplane’s maintenance records revealed no evidence of uncorrected mechanical discrepancies with the airframe or the engine. The maintenance records showed that a dorsal fin was installed onto the empennage in April 2020.
The airplane, which had flight controls at both positions, only had flight instruments for the front seat. The airplane was not equipped with flaps, a stall warning system, or an angle-of-attack indicator.
Meteorological Information
The estimated density altitude at the time of the accident was 2,610 ft above mean sea level (msl).
Wreckage and Impact Information
The airplane came to rest about 1,100 ft southeast of the departure end of runway 15, on a magnetic heading of 079° at an elevation of about 860 ft msl. All major components were found at the accident site. The airplane sustained substantial damage to the fuselage and both wings. Flight control continuity was established for both cockpit stations.
The single fuel tank, located between the cockpit and the firewall, was breached from the impact sequence. An FAA aviation safety inspector, who was on site the day of the accident, reported a strong odor of fuel at the accident site. There were no signs of a fuel leak on the airframe. Vegetation blighting was observed in the grass where the front of the airplane came to rest.
Postaccident examination of the airframe and engine revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.
Additional Information
The FAA Pilot’s Handbook of Aeronautical Knowledge discusses the effects of weight on an aircraft, noting that an overloaded aircraft may not be able to leave the ground or may exhibit poor flight characteristics. The publication FAA-P-8740-2, Density Altitude, states that reduced air density adversely affects aerodynamic performance and decreases engine horsepower output.
