What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Acft engine quit on take-off. (.4) according to the pilot, during the take off climb, approximately 50 feet above ground level, engine RPM dropped from 3000 RPM to about 2000 RPM, and altitude could not be maintained. The pilot maneuvered the aircraft to avoid obstructions ahead and performed a forced landing in a field adjacent to the runway. The aircraft nosed over on the landing roll, resulting in substantial damage. The pilot exited the aircraft with no injuries. Post crash examination of the engine revealed that the carburetor heat was in the `on' position. The wires that hold the carburetor heat box hose open were found bunched toward the bottom of the inlet to the box, allowing the hose to collapse, and starving the carburetor of air.
