Article 6U.K.Rules on the introduction of operating restrictions aimed at the withdrawal of marginally compliant aircraft
1.If the assessment of all available measures, including operating restrictions of a partial nature, carried out in conformity with the requirements of Article 5 demonstrates that the achievement of the objectives of this Directive requires the introduction of restrictions aimed at the withdrawal of marginally compliant aircraft, the following rules shall apply instead of the procedure laid down in Article 9 of Regulation (EEC) No 2408/92 at the airport under consideration:
(a)six months after the completion of the assessment and decision on the introduction of an operating restriction, no services over and above those operated in the corresponding period of the previous year shall be allowed with marginally compliant aircraft at that airport;
(b)not less than six months thereafter, each operator may be required to reduce the number of movements of his marginally compliant aircraft serving that airport at an annual rate of not more than 20 % of the initial total number of these movements.
2.Subject to the rules on assessment of Article 5, city airports listed in Annex I may introduce measures that are more stringent, in terms of the definition of marginally compliant aircraft provided that these measures do not affect civil subsonic jet aeroplanes that comply, through either original certification or recertification, with the noise standards in Volume 1, Part II, Chapter 4 of Annex 16 to the Convention on International Civil Aviation.
