What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft impacted the water / marsh near Beaufort, SC.
Departed kcpk at 1:45PM EST. Departed for an intended landing at kzph. About 2.5 hours into the flight, at approximately 4:20PM, and 1500 ft.~ AGL, the engine began to run extremely rough. I was forced into a controlled descent. I began emergency and investigative procedures. After switching the fuel tank selector , applying carburetor heat, enriching and leaning the fuel mixture, switching the auxiliary fuel pump on and off, and advancing/retarding the throttle, the engine only ran progressively worse in all settings. I pressed the nrst button on my handheld GPS and headed towards Beaufort. I had just enough time to make a mayday call without any response, before the engine quite completely. I estimate the total engine failure at 500 ft. AGL. I glided over the everglade like swamps before crashing into a small tributary stream.
