CHAPTER IIIPOWERS OF THE AIRCRAFT COMMANDER
Article 5
1. The provisions of this chapter shall not apply to offences and acts committed or about to be committed by a person on board an aircraft in flight in the airspace of the State of registration or over the high seas or any other area outside the territory of any State unless the last point of take-off or the next point of intended landing is situated in a State other than that of registration, or the aircraft subsequently flies in the airspace of a State other than that of registration with such persons still on board.
2. Notwithstanding the provisions of Article 1, paragraph 3, an aircraft shall, for the purposes of this chapter, be considered to be in flight at any time from the moment when all its external doors are closed following embarkation until the moment when any such door is opened for disembarkation. In the case of a forced landing, the provisions of this chapter shall continue to apply with respect to offences and acts committed on board until competent authorities of a State take over responsibility for the aircraft and for the persons and property on board.
Article 6
1. The aircraft commander may, when he has reasonable grounds to believe that a person has committed, or is about to commit, on board the aircraft, an offence or act contemplated by Article 1, paragraph 1, impose upon such person reasonable measures including restraint which are necessary:
(a)to protect the safety of the aircraft, or of persons or property therein; or
(b)to maintain good order and discipline on board; or
(c)to enable him to deliver such person to competent authorities or to disembark him in accordance with the provisions of this chapter.
2. The aircraft commander may require or authorize the assistance of other crew members and may request or authorize, but not require, the assistance of passengers to restrain any person whom he is entitled to restrain. Any crew member or passenger may also take reasonable preventative measures without such authorization when he has reasonable grounds to believe that such action is immediately necessary to protect the safety of the aircraft, or of persons or property therein.
Article 7
1. Measures of restraint imposed upon a person in accordance with Article 6 shall not be continued beyond any point at which the aircraft lands unless:
(a)such point is in the territory of a non-Contracting State and its authorities refuse to permit disembarkation of that person or those measures have been imposed in accordance with Article 6, paragraph 1 (c) in order to enable his delivery to competent authorities;
(b)the aircraft makes a forced landing and the aircraft commander is unable to deliver that person to competent authorities; or
(c)that person agrees to onward carriage under restraint.
2. The aircraft commander shall, as soon as practicable, and if possible before landing in the territory of a State with a person on board who has been placed under restraint in accordance with the provisions of Article 6, notify the authorities of such State of the fact that a person on board is under restraint and of the reasons for that restraint.
Article 8
1. The aircraft commander may, in so far as it is necessary for the purpose of subparagraph (a) or (b) of paragraph 1 of Article 6, disembark in the territory of any State in which the aircraft lands any person who he has reasonable grounds to believe has committed, or is about to commit, on board the aircraft an act contemplated in Article 1, paragraph (b).
2. The aircraft commander shall report to the authorities of the State in which he disembarks any person pursuant to this article, the fact of, and the reasons for, such disembarkation.
Article 9
1. The aircraft commander may deliver to the competent authorities of any Contracting State in the territory of which the aircraft lands any person who he has reasonable grounds to believe has committed on board the aircraft an act which, in his opinion, is a serious offence according to the penal law of the state of registration of the aircraft.
2. The aircraft commander shall as soon as practicable and if possible before landing in the territory of a Contracting State with a person on board whom the aircraft commander intends to deliver in accordance with the preceding paragraph, notify the authorities of such State of his intention to deliver such person and the reasons therefor.
3. The aircraft commander shall furnish the authorities to whom any suspected offender is delivered in accordance with the provisions of this article with evidence and information which, under the law of the State of registration of the aircraft, are lawfully in his possession.
Article 10
For actions taken in accordance with this Convention, neither the aircraft commander, any other member of the crew, any passenger, the owner or operator of the aircraft, nor the person on whose behalf the flight was performed shall be held responsible in any proceeding on account of the treatment undergone by the person against whom the actions were taken.
