Narrative:
15 September 2024: Cessna 152 G-CMAH was damaged when it overturned in a forced landing incident near Buntingford, Hertfordshire. The incident was the subject of an AAIB Record-only Investigation, and the following is the summary from the AAIB Report, published on 13 February 2025:

"During a training flight, as the student was initiating a climb from about 1,500 ft agl, the engine started to run roughly. Carburettor heat had been used in the descent prior to this manoeuvre. The instructor immediately took control of the aircraft but was unable to stop the engine’s deteriorating performance and maintain altitude. A forced landing was made, with limited field options given the low altitude, during which the nosewheel dug into the soft mud of a ploughed field, flipping the aircraft onto its back.

Damage Sustained to airframe
Per the AAIB report "the aircraft flipped over onto its back". According to the AirNav RadarBox website (see link #2) G-CMAH has not flown since this incident,
