COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Hose Assemblies
AD/HOSE/6 Hose Recall #2 - Buckeye Rubber Products 11/98
Applicability: All ½ inch to 3 inch diameter MIL-H-6000B rubber aircraft fuel system hose manufactured by Buckeye Rubber Products Inc (a US company) since
01 January 1994. These hoses may be fitted to Raytheon (formerly Beechcraft) 90, 100, 200 and 300 series airplanes (all models).
Requirement: 1 Replace all applicable fuel hoses which are identified as having been supplied and/or replaced between 01 January 1994 and 8 October 1998 (the effective date of this AD) in accordance with the directions of Raytheon Service Bulletin 2718 Rev 1 dated 01 June 1997.
The hoses are identified by a spiral or diagonal pattern external reinforcement wrap (Fig 1), a pronounced 3/8 inch wide lengthwise red-orange stripe on one side with the manufacturer’s code, 94519, printed periodically in red letters on one side, and/or on the other side by two faint parallel white lines showing quarter year and year of manufacture, hose size and specification number.
2. MIL-H-6000 rubber hose manufactured by Buckeye Rubber Products since 01 January 1994 shall not be installed on an Australian registered aircraft.
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.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive framework for ensuring the safety and efficiency of civil aviation. Part 39, which focuses on airworthiness directives, was introduced to address the need for timely and effective measures to maintain aircraft safety. Specifically, Schedule 107 of the Civil Aviation Regulations 1998 aims to mandate directives that ensure aircraft remain in a condition that is safe for operation. One such directive, AD/HOSE/6, issued by the Civil Aviation Safety Authority, targets a significant safety issue involving fuel hoses manufactured by Buckeye Rubber Products between 1 January 1994 and 8 October 1998. These hoses, which were prone to internal collapse, posed a catastrophic risk if not replaced. The directive requires the replacement of all identified hoses and prohibits the installation of new Buckeye Rubber Products hoses on Australian registered aircraft, aligning with the policy objective to mitigate risks and maintain the highest safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 107, establishes the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, which includes AD/HOSE/6, a directive concerning hose assemblies. This particular directive applies to all ½ inch to 3 inch diameter MIL-H-6000B rubber aircraft fuel system hoses manufactured by Buckeye Rubber Products Inc, a US company, since 01 January 1994. These hoses are used on various Raytheon (formerly Beechcraft) 90, 100, 200, and 300 series airplanes. The directive mandates the replacement of all applicable fuel hoses supplied and/or replaced between 01 January 1994 and 08 October 1998, the effective date of this directive, as outlined in Raytheon Service Bulletin 2718 Rev 1 dated 01 June 1997. The identification of the affected hoses is based on their physical characteristics, including a spiral or diagonal pattern external reinforcement wrap, a red-orange stripe with specific manufacturer codes, and faint parallel white lines indicating the quarter year and year of manufacture, hose size, and specification number. Additionally, the directive prohibits the installation of MIL-H-6000 rubber hoses manufactured by Buckeye Rubber Products since 01 January 1994 on Australian registered aircraft. Compliance with the directive requires replacement within 200 flight hours or six months of the effective date, or as of the effective date if already in service.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 107, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives (ADs). AD/HOSE/6 pertains to the recall of hose assemblies made by Buckeye Rubber Products, addressing safety concerns related to MIL-H-6000B rubber aircraft fuel system hoses. These hoses, which are applicable to all ½ inch to 3 inch diameter hoses manufactured by Buckeye since 1 January 1994, are used in various Raytheon aircraft models. The directive mandates the replacement of all affected hoses that were supplied or replaced between 1 January 1994 and 8 October 1998, the effective date of this AD. Such hoses are identifiable by specific physical characteristics, including a spiral or diagonal pattern on the external reinforcement, a pronounced red-orange stripe with manufacturer code 94519, and faint parallel white lines indicating the quarter year and year of manufacture, hose size, and specification number.
Entities governed by this AD, such as aircraft owners, operators, and maintenance providers, must comply with the specified requirements. They must ensure that all applicable hoses are replaced within 200 flight hours or six months from the effective date of the directive. For hoses identified as defective, they must adhere to the instructions outlined in Raytheon Service Bulletin 2718 Rev 1 dated 1 June 1997. Additionally, any new installation of Buckeye-manufactured MIL-H-6000 rubber hoses on Australian registered aircraft is strictly prohibited.
Failure to comply with the Airworthiness Directive AD/HOSE/6 may result in significant consequences. CASA enforces strict measures to ensure adherence to these safety directives. Violations of these regulations can lead to enforcement actions by CASA, which may include fines and other penalties. The potential for catastrophic failure of the defective hoses underscores the importance of strict compliance. The regulations are designed to protect the safety of aircraft operations and ensure that only safe, approved components are used in Australian registered aircraft.
