Transport Airship Requirements March 2000 submitted by: Rijksluchtvaartdienst Luftfahrt-Bundesamt Saturnusstraat 50 Hermann-Blenk-Strasse 26 2132HB Hoofddorp D-38108 Braunschweig The Netherlands Germany www.minvenw.nl/rld www.lba.de TAR Intentionally left blank TAR - Transport Airship Requirements March 2000 2 of 117 TAR AIRWORTHINESS REQUIREMENTS FOR TRANSPORT CATEGORY AIRSHIPS Foreword 1 The Civil Aviation Authorities Luftfahrt-Bundesamt of Germany and Rijksluchtvaartdienst of The Netherlands have agreed common comprehensive airworthiness requirements for large airships to accomodate Type Certification applications for such aircraft in their countries. The new category Transport Airships is defined in Appendix C. 2 Existing airworthiness codes FAR P8110-2 of the Federal Aviation Administration of the United States of America and JAR-25 of the Joint Aviation Authorities of Europe have been selected to form the basis of these Transport Airship Requirements (TAR). 3 Certain of the requirements of this TAR, in particular those in Subpart F, call for the installation of equipment and in some cases prescribe requirements for the design and performance of that equipment. These requirements, in common with the remainder of the TAR, are intended to be acceptable to the Authorities as showing compliance, but it should be borne in mind that an importing country may require equipment additional to those in this TAR for operational purposes. 4 The performance requirements of Subparts B and G have been developed on the assumption that the resulting scheduled performance data will be used in conjunction with airship performance operating rules which are complementary to these performance requirements. 5 Terms used in this TAR are as contained in JAR-1, "Definitions and Abbreviations". Airship related Definitions and Abbreviations are presented in Appendix C. 6 Future development of the requirements for this TAR will be in accordance with an agreed amendment procedure. The two Aviation Authorities have agreed they should not unilaterally initiate amendment of the code. 7 Amendments to the text in this TAR will usually be issued initially as 'Orange Paper' Amendments. 8 Comment/Response Documents developed following Notice of Proposed Amendment (NPA) consultation produced by the two Aviation Authorities as a method of publicly responding to comments received are published with each Orange Paper amendment (OP) that contains the affected proposals. These texts will not be reproduced when those OPs are incorporated into a Change. Readers should therefore either retain Comment/Response Documents for future reference, or apply to the two Aviation Authorities for copies of specific Comment/Response Documents as required. 9 Units are transformed according the SI-system. However, in some cases the units where kept in order not to alter the known shape. TAR - Transport Airship Requirements March 2000 3 of 117 TAR Intentionally left blank TAR - Transport Airship Requirements March 2000 4 of 117 TAR Preambles 31.3.2000 The TAR consists of nine Subparts including subparts J for APUs, and 3 Appendices. Section 1 - Requirements 1 General I. This code is originally based on P8810-2 of the Federal Aviation Regulations, named Airship Design Criteria, applicable for conventional, near-equilibrium non-rigid airships with nine passenger seats or less, and it is termed "Transport Airship Requirements". JAR-25 requirements for large airplanes have been considered and incorporated where applicable to achieve a comparable level of safety. II. Several JAR-25 NPAs, which face incorporation in the JAR-25 text in the near future, have been considered and incorporated where applicable in the TAR. III. The definition of Transport Airships in Appendix C encompasses all types of construction, whether they be non- or semi-rigid, conventional rigid, metal rigid or metal pressure airships and whether they perform horizontal or vertical take-offs and landings. 2 Presentation I. The requirements of TAR are presented in two columns on loose pages, each page being identified by the date of issue or the Change number under which it is amended or reissued. A checklist of pages will be provided when the first changes are incorporated. II. In general, the TAR paragraphs carry the same number as the corresponding FAR- or JAR paragraph. In cases where new airship material is introduced, and there is no corresponding paragraph in FAR/JAR, a number is chosen for it which attempts to place the new material in the right context within the FAR/JAR numbering system. III. AC material is now shown in the related paragraphs but will be taken up in a new Section 2 in later issues. IV. Advisory material is now shown in the related paragraphs but will be taken up in a new Section 3 in later issues. V. Where appropriate, reference is made to existing JAR-25 ACJ and AMJ material. VI. New, amended and corrected text is enclosed within heavy brackets [ xx ].
