On December 31, 2019, about 1415 central standard time, an Enstrom F28A helicopter, N57SJ, sustained substantial damage when it nosed over during a forced landing following a partial loss of engine power. During the nose-over, the tailboom was separated and the main rotor system and fuselage were damaged. The student pilot and flight instructor were not injured. The helicopter was registered to and operated by a private individual under the provisions of Title 14 Code of federal Regulations Part 91 as an instructional flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The local flight originated from the Salaika Aviation Airport (07TA), Danbury, Texas, at an unconfirmed time.

The instructional flight was operating about 75 ft. above the trees when a partial loss of engine power was experienced. Unable to maintain flight with the reduced engine power, the instructor pilot attempted an autorotation to a nearby field. Upon touching down the helicopter's skids sunk into the muddy soil and the helicopter nosed over. During the nose-over, the main rotor blades contacted the tail boom, severing it just forward of the tail rotor gearbox.
