Sec. 78.21. Parking and storing of aircraft

Parking and storing of aircraft at the airport shall be accomplished in the manner prescribed by the airport operator in locations designated by the manager for such parking and storage. The following conditions shall apply:

(a) Aircraft tie-down.

No person shall park an aircraft or leave the same standing at any place on the airport other than inside a hangar unless it is firmly tied to the ground in the manner prescribed by the airport operator. The main landing wheels shall be chocked with wheel blocks or other approved devices, except in cases where, in the opinion of the airport operator, other proven procedures are equally safe. In addition to the above, helicopters shall have braking devices and/or rotor mooring blocks applied to the rotor blades.

(b) Transient parking.

Operators may park or leave standing an aircraft in areas designated by the airport operator for transient parking provided the aircraft is secured to the ground in the manner described in subdivision (a) of this section.

(c) Movement of parked or stored aircraft.

Upon direction from the airport operator, the operator of any aircraft parked or stored at the airport shall move said aircraft from the place where it is parked or stored to any other designated place. Should the operator refuse to comply with such direction, the airport operator may tow said aircraft to such designated place at the operator's expense and, if such direction was reasonable under the circumstances, without liability for damage which may result in the course of such moving.
