Narrative:The pilot was being vectored for an ILS approach when he activated the runway edge lighting. He said he saw the lights as he was being vectored to the final approach course. While on final approach he extended the landing gear and illuminated the landing lights. The lights caused a cockpit glare and he turned them off. As the airplane was passing through 500 feet above ground, he turned the landing lights on a second time. He said he saw a big glow and turned the lights off a second time. After he did this he said he saw nothing. The airplane collided with the ground and MASLR light stand. It was found about 1 hour and 15 minutes after the ground collision. A searcher said the visibility was about 400 feet. The pilot said he was aware of a NOTAM about the inoperative VASI, REIL, and Medium Intensity Approach Lighting System and Runway Alignment Indicator (MASLR). An FAA CAMI optometrist was told the circumstance's surrounding the accident. He said what the pilot experienced was a '...classic case of flash blindness.' Information he provided showed the pilot would have a blind gap in his visual field under circumstances he encountered.
Probable Cause: the pilot's inability to maintain visual contact with the runway environment due to 'flash blindness' when he turned on the airplane's landing light, and his subsequent inability to regain control of the airplane after turning off the landing light due to his loss of night vision. A factor was the bright light condition encountered by the pilot.
