What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) While conducting a visual approach to runway 24 at the st. Augustine, Florida airport (sgj), following an IFR flight, the aircraft touched down approximately 150 feet short or prior to the runway threshold. One of the main landing gears caught the edge of the runway threshold causing the left and right main gear to collapse. The nose gear remained extended and locked in the down position. This impact caused the aircraft to spin out of control and depart the left side of the runway and came to rest approximately 300 feet from the first point of impact, in the grass, between runways 13 and 24. The aircraft left wing was torn loose from the aircraft along with major damage to the main spar and multiple wing ribs.
