What happened
On January 9, 2009, a Cirrus SR20, registration PR-RAT, was performing a flight from Goiânia to the Santa Rosa Farm airstrip (SJSR) in Mara Rosa, Goiás. The aircraft was carrying a pilot and one passenger. During the final approach to runway 01, the pilot conducted an unstabilized approach characterized by an excessive descent rate and airspeed higher than standard parameters.
Despite recognizing that the approach was not stabilized, the pilot continued the landing. The aircraft touched down beyond the ideal touchdown point. Due to the high speed and the aircraft's position on the runway, the pilot was unable to decelerate sufficiently before reaching the end of the runway. The aircraft overran runway 19 by approximately 20 meters. The landing gear sustained severe damage, and the propeller suffered minor damage, but both occupants escaped without injury.
The investigation
CENIPA investigators examined the aircraft's performance, the pilot's actions, and the runway conditions. The investigation confirmed that the aircraft was within weight and center of gravity limits and was airworthy. Meteorological data showed that while visibility was good, recent light rain had left the asphalt surface damp.
Investigators noted that the runway surface at the Santa Rosa Farm airstrip was partially covered with low-lying vegetation, particularly in the final 300 meters of the runway. This vegetation, combined with the moisture from recent rainfall, significantly reduced tire traction and braking effectiveness. The investigation also analyzed the pilot's decision-making regarding the unstabilized approach and the potential for a go-around.
