10.4.2010 Official Journal of the European Union L 90/1 (Non-legislative acts) II REGULATIONS COMMISSION REGULATION (EU) No 297/2010 of 9 April 2010 amending Regulation (EC) No 272/2009 supplementing the common basic standards on civil aviation security (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 300/2008 of the European Parliament and of the Council of 11 March 2008 on common rules in the field of civil aviation security and repealing Regu- lation (EC) No 2320/2002 () and in particular Article 4(2) thereof, Whereas: G) General measures supplementing the common basic standards on civil aviation security should be adopted in the field of screening, access control and other security controls as well as in the field of prohibited articles, third country recognition of equivalence, staff recruitment, training, special security procedures and exemptions from security controls. These general measures are necessary in order to achieve a common level of aviation security within the European Union to protect the travelling public from acts of unlawful interference. One-stop security is the main facilitating element offered by EU legislation. Therefore the harmonisation of screening methods is essential in order to maintain one-stop security within the EU including controls of liquids, aerosols and gels without impeding the benefits of the Single aviation market for EU citizens. The Annex to Commission Regulation (EC) No 272/2009 of 2 April 2009 supplementing the () OJ L 97, 9.4.2008, p. 72. common basic standards on civil aviation security laid down in the Annex to Regulation (EC) No 300/2008 of the European Parliament and of the Council (3), details in its Part A.3 the methods of screening allowed for baggage, cargo and mail which is to be loaded into the hold of an aircraft. It is necessary from time to time to make provision for additional methods of screening shown to be effective for screening some or all types of cargo and to provide a legal basis for the development of detailed implementing measures. Metal detection equipment is considered to be an effective screening method for some types of cargo. Regulation (EC) No 272/2009 does not provide for liquids, aerosols and gels to be considered as a category of articles that may be prohibited from intro- duction into security restricted areas and on board an aircraft. Instead Regulation (EC) No 272/2009 requires methods, including technologies, for detection of liquid explosives to be deployed on an EU-wide basis at airports as swiftly as possible, but no later than 29 April 2010. It is now time to put an end to the restrictions on liquids, aerosols and gels, moving progressively from banning most liquids to a system of screening for liquid explosives. To this end, transitional arrangements beyond April 2010 are required to phase-in the deployment of detection methods, including tech- nologies, at all EU airports without compromising aviation security. The concerns of the law enforcement community, aimed at preventing possible terrorist threats in the future, require an effective mechanism in place until airports are in a position to install reliable detection equipment. Therefore a new approach is needed. This should be achieved by 29 April 2013, the date by which all airports should have the capability to screen liquids, aerosols and gels.
