N426SP

The pilot reported that he intended to complete three full-stop landings at night, to meet currency requirements. During the first landing, the airplane bounced three times and veered left. The pilot applied right rudder and right aileron in an attempt to correct; however, the nosegear struck a snowbank off the left side of the runway. During the collision, the airplane nosed over and came to rest inverted. The pilot added that there were no preimpact mechanical malfunctions with the airplane and the wind was reported as calm about the time of the accident. Examination of the airplane by a Federal Aviation Administration inspector revealed substantial damage to the right wing and vertical stabilizer.
