During his first approach the pilot noted that it was a very dark night, and that there were some brightly shining "flood lights" in his eleven o'clock position while he was on short final for landing. Even though the flood lights were "limiting" his vision, his first landing was successful. After the first landing, the pilot hovered near the touchdown point for a few minutes, and then was cleared by the tower to proceed around the pattern for another landing. When the pilot was on short final for the second landing, while the helicopter was still about 50 feet above the ground, he saw the low rotor rpm light flicker. He therefore reduced collective and checked the rpm gage, which showed that both the engine and rotor rpm were where they should be. Soon thereafter the helicopter impacted the runway surface. The flickering of the warning light, along with the pilot's glance at the rpm gage, caused him to momentarily be distracted, and that, along with the effect of the food lights and the dark night, resulted in him not seeing the ground in time to initiate a landing flare.
Probable Cause: The pilot's failure to initiate a flare prior to contacting the ground while attempting to land the helicopter on a dark night. Factors include a distraction created by the flicker of a low rotor rpm light, the glare of nearby flood lights, and the lack of ambient illumination of the landing area.
