On July 11, 2021 at about 1:10 am local time, a 1965 Cessna 150, registered N8172S, was substantially damaged in an accident during initial climb near Elba, Alabama (Carl Folsom Airport). It was an instructional flight under general aviation rules (Part 91). No one was hurt; 2 people were on board or involved. The weather was visual conditions (good weather).
The NTSB's probable cause their words, unchanged
The partial loss of engine power due to the formation of carburetor ice, which resulted in reduced climb capability and impact with trees during takeoff.

The NTSB's narrative final · quoted from the NTSB record
After performing flight training maneuvers for about 30 minutes, the instructor and student returned to the airport to practice short/soft field takeoffs and landings. After the first full-stop landing, the flight instructor recalled applying carburetor heat during the landing and taxi back for the next takeoff. During the student’s subsequent short field takeoff, the airspeed did not increase as expected while in ground effect and the instructor asked the student why he was not climbing. The student replied that he didn’t know and relinquished the controls to the instructor. The instructor determined that the engine was not producing enough power to maintain level flight and that they were too low to troubleshoot. As the airplane descended and the airspeed decreased, she lowered the nose and made a forced landing into trees, which resulted in substantial damage to the wings and fuselage. After the accident the flight instructor stated she thought the cause was carburetor ice. The temperature and dewpoint at the time of the accident were conducive to serious icing at glide power, and carburetor ice likely accumulated during the approach and previous landing. Although the instructor recalled applying carburetor heat during taxi there may not have been sufficient time to melt all or any accumulated carburetor ice.
