DECISION No 2005/07/R OF THE EXECUTIVE DIRECTOR OF THE AGENCY of 19-12-2005 amending Decision No 2003/19/RM of 28 November 2003 on acceptable means of compliance and guidance material to Commission Regulation (EC) No 2042/2003 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks THE EXECUTIVE DIRECTOR OF THE EUROPEAN AVIATION SAFETY AGENCY, Having regard to Regulation (EC) No 1592/2002 of 15 July 2002 on common rules in the field of civil aviation (hereinafter referred to as the Basic Regulation) and establishing a European Aviation Safety Agency1 (hereinafter referred to as the “Agency”), and in particular Articles 13 and 14 thereof. Having regard to the Commission Regulation (EC) No 2042/2003 of 28 November 2003 on the continuing airworthiness of aircraft and aeronautical products, parts and appliances, and on the approval of organisations and personnel involved in these tasks.2 Whereas: (1) Annex IV Acceptable Means of Compliance to Part- 66 Appendix 1 Aircraft type ratings for Part-66 aircraft maintenance licence (hereinafter referred to as Part-66 AMC Appendix I) is required to be up to date to serve as reference for the national aviation authorities. (2) To achieve this requirement the text of Part-66 AMC Appendix I should be amended regularly to add new aircraft type rating. (3) The regular amendment of Part-66 AMC Appendix I is considered as a permanent rulemaking task for the Agency. This decision represents the first update according to an accelerated procedure accepted by AGNA and SSCC. -
