The Convention for the Unification of Certain Rules for International Carriage by Air, concluded in Montreal on 28 May 1999, is not decisive for the interpretation of the grounds of exemption under Article 5(3) of Regulation No 261/2004.

2. The frequency of the technical problems experienced by an air carrier is not in itself a factor from which the presence or absence of ‘extraordinary circumstances’ within the meaning of Article 5(3) of Regulation No 261/2004 can be concluded.

3. The fact that an air carrier has complied with the minimum rules on maintenance of an aircraft cannot in itself suffice to establish that that carrier has taken ‘all reasonable measures’ within the meaning of Article 5(3) of Regulation No 261/2004 and, therefore, to relieve that carrier of its obligation to pay compensation provided for by Articles 5(1)(c) and 7(1) of that regulation.
