Applicability: All aircraft hose supplied by Buckeye Rubber products (a US company) between March 1995 and June 1997 (the effective date of this directive). In particular, any hoses fitted to Cessna Aircraft Company and Reims Aviation 100, 200, 300 and 400 Series aircraft as Cessna Part No. S51-10 between March 1995 and June 1997. All applicable hose held in stock at aircraft maintenance facilities.
Note: FAA AD 97-01-13 Amdt 39-9884 and Cessna Service Bulletin SEB 96-15 refer.

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.
Currently, Cessna and Reims are the only aircraft manufacturers who can be identified as having been supplied with this defective stock. Further investigations with the product supplier are taking place to identify all aircraft manufacturers which have been supplied with the defective stock. This AD will be amended as soon as this information becomes available.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 107, outlines various airworthiness directives issued by the Civil Aviation Safety Authority (CASA) to address safety concerns in aviation. One such directive, AD/HOSE/5, was enacted in response to a critical safety issue identified in hoses supplied by Buckeye Rubber Products to certain aircraft between March 1995 and June 1997. This directive was introduced to address the potential for internal collapse in hoses fitted to Cessna and Reims Aviation aircraft, which could result in catastrophic failures in fuel, oil, or hydraulic systems. The directive mandates the replacement of all affected hoses within 60 days of its effective date, 19 June 1997, and it reflects a collaborative effort with the Federal Aviation Administration (FAA) to ensure comprehensive safety measures are implemented. The policy objective of this directive is to mitigate the risk of in-service failures by ensuring the removal and replacement of the identified defective hoses.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 107, mandates the application of Airworthiness Directives (AD) concerning hose assemblies for aircraft. This legislation applies to all hoses supplied by Buckeye Rubber Products, a US company, to aircraft between March 1995 and June 1997. The directive is particularly focused on hoses installed in Cessna Aircraft Company and Reims Aviation 100, 200, 300, and 400 Series aircraft, identified by Cessna Part No. S51-10. Additionally, any such hoses held in stock at aircraft maintenance facilities fall under the scope of this directive. The directive is effective from 19 June 1997 and requires compliance within 60 days of its effective date. The legislation extends to replacing all applicable fuel, hydraulic, or oil hoses that were supplied and/or replaced between March 1995 and April 1997, identified by their spiral or diagonal pattern external reinforcement wrap. This directive is a critical safety measure responding to the discovery of an unsafe condition in a batch of hoses prone to internal collapse, with the potential for catastrophic failure in fuel, oil, or hydraulic lines.
Key Provisions
The Civil Aviation Safety Authority's Airworthiness Directive (AD) AD/HOSE/5, as detailed in Part 39 - 107 of the Civil Aviation Regulations 1998, specifically targets the replacement of certain hose assemblies from Buckeye Rubber Products. This directive applies to all hoses supplied by Buckeye Rubber Products between March 1995 and June 1997. The primary requirement is the replacement of all fuel, hydraulic, or oil hoses that were identified as having been supplied and/or replaced between March 1995 and April 1997, and which exhibit a spiral or diagonal pattern external reinforcement wrap. This replacement must be completed within 60 days of the directive's effective date, which is 19 June 1997.
The obligations imposed by this directive are clear and direct. Aircraft operators, maintenance facilities, and other relevant parties must ensure that all affected hoses are identified and replaced in accordance with the directive's requirements. This includes conducting thorough inspections of all hoses supplied by Buckeye Rubber Products within the specified timeframe and replacing those that meet the criteria outlined in the directive. Additionally, maintenance facilities must maintain records of all inspections and replacements carried out in compliance with this directive, as these records may be required for verification purposes by the Civil Aviation Safety Authority.
The consequences of non-compliance with this Airworthiness Directive can be severe. Failure to replace the defective hoses as required by the directive could result in significant safety risks, including the potential for catastrophic failures in fuel, oil, or hydraulic lines. Such failures could lead to serious accidents and loss of life. From a regulatory perspective, non-compliance may result in enforcement actions by the Civil Aviation Safety Authority, which could include fines, penalties, or other sanctions. The specific penalties for non-compliance are not detailed in the directive itself, but they could include substantial financial penalties and potential criminal charges if the non-compliance leads to an aviation accident or incident.
