The pilot stated that he received an instrument flight rules clearance from air traffic control for a night global positioning system approach to runway 24 at his destination airport. Upon reaching the final approach fix, he turned the landing lights on, lowered the landing gear and extended the flaps to the full down position. He observed both alternator lights flicker, then remain illuminated. He continued the approach and flared the airplane higher than normal. The airplane landed hard and bounced several times. The pilot lost directional control of the airplane, and it departed the left side of the runway and came to rest upright in the grass. Examination of the airplane revealed structural damage to the landing gear, right wing, and fuselage, consistent with ground impact. Weather, about the time of the accident, included clear skies and winds from 190 degrees true at 8 knots.
