Article 21
The application for a heliport or the takeoff and landing areas for free balloons of a temporary nature shall be filed to CAA by submitting the following documents for the latter to conduct a review. The use of the heliport may not commence until CAA has done a satisfactory review. The CAA may conduct an on-site inspection if it deems necessary:
1. Information regarding the aircraft to be used;
2. Airfield planes, current photographs of the takeoff and landing areas and the adjacent environs, excluding application of the takeoff and landing areas for free balloons of a temporary nature;
3. Supporting documentation for consent of use of the airport premises; and
4. Plan of uses.
The phrase "of a temporary nature" referred to in the preceding paragraph shall mean a situation wherein, under visual weather conditions, the period of use for each application does not exceed three months. But the period of use for application for the takeoff and landing areas for free balloons of a temporary nature could be extended to six month if there are proper reasons and be accepted by the CAA.
