The pilot reported that, while en route, he used left rudder to stay coordinated and alternated his left and right leg due to muscle fatigue. During landing at the destination airport, the approach was stabilized and "felt normal" with the flaps set at 100%. During the landing flare, he used "very little rudder" to maintain centerline, and, about 1 to 2 feet above the ground, the airplane suddenly yawed to the left about 30 to 45°. He added that there was not enough right rudder to maintain parallel with the runway, so he decided to go around. He applied power, the airplane yawed violently to the left, the airplane impacted the ground, exited the runway to the left, and came to rest in the grass to the left of a parallel taxiway. The airplane sustained substantial damage to the fuselage. The owner provided flight data from the accident flight. Examination of the data revealed that, within 25 seconds of the accident, the airplane descended from 782 ft mean sea level (msl) to 619 msl with descent rates peaking around 1019 ft per minute and the indicated airspeed decreased from 86 knots to 60 knots. About 2 seconds before the accident, the pitch attitude peaked at 7° with a left roll of 16°. The airport elevation was about 638 ft. The airplane was also equipped with a crash hardened Recoverable Data Module (RDM), a flight recording device installed in the tail of the airplane. Examination of the data recovered from the RDM and revealed that the airplane veered left, the power and pitch were momentarily increased, and the stall warning horn was on. The airplane manufacturer's recommended landing approach speed with flaps set to 100% was 80 to 85 knots. The aerodynamic stall speed at maximum gross weight was about 60 knots. The pilot reported that the wind was light and variable and not gusting. The RDM data revealed that the wind was from 359° at 5 knots. The pilot was landing the airplane on runway 19L. The Federal Aviation Administration inspector reported that he examined the airplane and verified rudder control continuity and that "everything was intact."
