Unless prior arrangements have been made with the Director of Macau International Airport, all landing, parking, and refuelling charges due and payable in respect of an aircraft shall be payable before the aircraft leaves the Macau International Airport (hereafter, the Airport). The Director may refuse to give clearance for that aircraft to depart or for any other aircraft that is operated by the operator of that aircraft to depart until such charges have been paid.

For as long as an aircraft is upon the Airport the Director shall have a lien, both particular and general, over the aircraft, its parts and accessories for all charges that shall be or become due and payable to the Director in respect of the aircraft or in respect of any other aircraft that is operated by the operator of that aircraft. The lien shall not lapse or be lost by reason of the aircraft departing from the Airport, but shall continue and be exercisable at any time when the aircraft shall return to and be upon the Airport for as long as the said charges shall remain unpaid.
