On October 07, 2025, at 1440 eastern daylight time, a Cessna 172M, N433PT, was substantially damaged when it was involved in an accident near Miami, Florida. The private pilot and the flight instructor were uninjured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight. The flight was an instructional flight for the private pilot to practice commercial pilot maneuvers in preparation for the pilot's commercial check ride. The pilots departed from Miami Executive Airport (TMB), Miami, Florida and proceeded southwest to an area to perform the maneuvers. The pilots reported performing multiple chandelles and an accelerated stall. After completing the accelerated stall, the pilots performed a simulated emergency descent. After recovering about 550 ft above ground level, they began a climb out. The pilots reported that after climbing about 300 ft, the engine started to act “erratically” and there was a loss of about 500 rpm. The pilots stated that the airplane would not climb and then determined that a forced landing would be required. The pilots landed the airplane in a shallow-water area of the Florida Everglades; during the landing, the airplane flipped over. A postaccident examination of the airplane revealed that it had sustained substantial damage to the left wing, vertical stabilizer, and rudder. The wreckage was retained for further examination.
