the hydrostatic test must be carried out.

             4.  It is a requirement of the various State OH&S and Gas laws that only cylinders that have been inspected in accordance with AS 2030.1-2009 can be refilled.  These laws are applicable to the cylinders used in hot air ballooning, and the Authority has no jurisdiction over this aspect.  Hence, it is possible for foreign sourced cylinders to be acceptable to the Authority for the purpose of a Type Certificate, but not be in compliance with the law/s of the State/s.

             In such circumstances, while it may be legitimate to use such cylinders for an aviation purpose, they may not be refilled under the terms of a State's regulatory requirement.

             CASA has no responsibility whatsoever for such matters and the owner/CofR holder is responsible for seeking compliance with the law/s of the State/s.

             5.  As stated in Note 3 above, AS 2030.5-2009 also invokes the tests and inspections required by the cylinder standard and/or the manufacturer.  Hence compliance with the requirement above also necessitates compliance with the intervals listed in those documents.

             6.  The physical configuration of the cylinder and its fittings must be as approved by the balloon manufacturer unless any changes are covered by an STC or other approval (ie, CAR 35).  Simply replacing a component with another of the same part number may result in configuration changes, because gas component manufacturers may change the design of a component without changing the part number.  It is particularly important that any changes to valves, regulators or other fittings on the top of a gas cylinder be carefully monitored.  Gas equipment maintenance personnel do not usually have detailed information regarding appropriate fittings for balloon fuel cylinders.
Compliance:  For Requirement 1:  In accordance with the inspection intervals specified by Australian Standard AS 2030.5-2009.

             For Requirement 2:  At the expiration of the service life limitation specified by the cylinder specification and/or manufacturer.
             This Amendment becomes effective on 9 July 2010.
Background:  This AD was initially raised in order to combine the aviation requirements of AD/GAS/1 and State legislative requirements, and also allow for the operational usage of balloon fuel cylinders.  Since the initial issue and subsequent amendment, a number of the original assumptions used in those issues were found to have changed.

             Amendment 2 addressed those changes, and provided some relief to operators in that the requirement for routine hydrostatic inspection was removed.

   Amendment 2 also stipulated a retirement life for cylinders based on certain assumptions regarding operational usage.  Information subsequently provided by, and on behalf of, the Australian Ballooning Federation, shows that some of those assumptions were incorrect and that the accumulation of fatigue damage and estimated crack propagation rates, are much less rapid
