COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES Note: FAA AD 9815-13 Amendment 39-10664 effective 28 August 1998 refers. Compliance: 1. Within 200 flight hours or six months of the effective date of this Directive. 2. As of the effective date of this Directive. This Airworthiness Directive becomes effective on 8 October 1998. Background: An unsafe condition has been discovered in a batch of MIL-H-6000B aircraft fuel system hose (particularly that delivered to Raytheon) from Buckeye Rubber products which is prone to internal collapse. The result of such a failure in fuel lines could be catastrophic and so the defective product needs to be identified and removed from service. The means of identification of the defective hose is by the date of fitment, the physical appearance of the hose and the markings on the outside of the hose to identify its source or part number.
