COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES

Compliance: Within 60 days of the effective date of this Directive.

This Airworthiness Directive becomes effective on 19 June 1997.

Background: An unsafe condition has been discovered in a batch of aircraft hose (particularly that delivered to Cessna/Reims) from Buckeye Rubber products which is prone to internal collapse. The result of such a failure in fuel, oil or hydraulic lines could be catastrophic and so the defective product needs to be identified and removed from service. The only means of identification of the defective hose is by the date of fitment and the physical appearance of the hose. There are no markings on the outside of the hose to identify its source or part number.
