The landing and take-off area of every location approved or used as a helistop shall consist of a hard-surfaced or grassed area with good drainage and free of dust and gravel. Each helistop landing and take-off area shall be circular or rectangular in shape; if circular, the diameter, or if rectangular, any side dimension, of such landing and take-off area shall be at least twice the length of any helicopter using it. Such area shall be set aside exclusively for taking off and landing, shall be free of trees, wires or other obstructions and shall be enclosed by a fence at least two feet in height.
Every helistop shall have at least two approach paths free and clear of obstructions extending outward and upward from the landing and take-off area at an angle of eight feet horizontally to one foot vertically, flaring to a width of 500 feet at an altitude of 500 feet. The center line of such approach paths or planes shall be separated by an arc of at least 135 degrees. The remaining peripheral area surrounding the landing and take-off area shall be free and clear of obstructions at an angle of two feet horizontally to one foot vertically to a lateral distance of 250 feet from the landing and take-off area.
No approach path shall be used and no helicopter shall be flown at an elevation of less than 500 feet over a residence building, school or other public building, and not less than 200 feet over any other building or public highway, except for the purpose of landing or taking off from an approved helistop.
No fueling, repairing or maintenance of helicopters shall be performed at such helistop, except in case of emergency, and no fuel shall be stored.
