The NTSB's narrative final · quoted from the NTSB record

During the landing roll, the right main landing gear dropped into a mud hole covered by 6 inch tall Bermuda grass. The tire pushed up the mud instead of rolling through the hole, and the airplane came to a sudden stop and nosed over to the inverted position.
