COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 3100 (Jetstream) Series Aeroplanes
AD/JETSTREAM/6 Inboard Wing Leading Edge Hydraulic Lines 8/85
Applicability: All model Jetstream Series 3100 with S/Nos. 601 to 636. Requirement: British Aerospace SB29-JA840508 Rev. 1.
Compliance: Within 300 flying hours from 31 AUGUST 1985.
Background: Chafing of the suction and pressure hydraulic lines in the inboard wing leading edge can result in complete hydraulic failure due to loss of fluid.
Overview
The Civil Aviation Regulations 1998, amended by the Legislative Instrument F2006B10930, was enacted to address critical safety concerns in civil aviation, specifically targeting the maintenance and airworthiness of aircraft. This regulation was introduced to ensure that certain British Aerospace BAe 3100 (Jetstream) Series Aeroplanes meet specified safety standards. The regulation, established by the Australian Government through the Civil Aviation Safety Authority, aims to mitigate the risk of hydraulic failure due to chafing of hydraulic lines in the inboard wing leading edge of affected aircraft. The policy objective is to enhance flight safety by mandating timely and specific compliance with the safety directive issued by British Aerospace.
This regulation applies to all model Jetstream Series 3100 with serial numbers between 601 and 636, requiring compliance with British Aerospace Service Bulletin SB29-JA840508 Rev. 1 within 300 flying hours from 31 August 1985. The directive is designed to prevent potential hydraulic failures that could arise from the chafing of suction and pressure hydraulic lines, thereby ensuring the continued safety and airworthiness of these aircraft in operation.
Scope and Application
The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically AD/JETSTREAM/6, pertains to the Jetstream Series 3100 aeroplanes with serial numbers ranging from 601 to 636. This legislation is applicable to the entities operating these specific models, requiring adherence to the British Aerospace Service Bulletin SB29-JA840508 Rev. 1, which mandates compliance within 300 flying hours from 31 August 1985. The directive is designed to address the critical issue of hydraulic line chafing in the inboard wing leading edge, which poses a significant risk of complete hydraulic failure due to fluid loss. This safety regulation extends to all operators of the affected Jetstream Series 3100 aeroplanes, ensuring that these aircraft maintain the necessary structural integrity and operational safety standards to mitigate potential hazards.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, includes AD/JETSTREAM/6 which pertains to the British Aerospace BAe 3100 (Jetstream) Series aeroplanes. This directive, focusing on inboard wing leading edge hydraulic lines, applies to all model Jetstream Series 3100 aeroplanes with serial numbers ranging from 601 to 636. The requirement outlined in this directive mandates compliance with British Aerospace Service Bulletin SB29-JA840508 Rev. 1, which addresses the issue of chafing of the suction and pressure hydraulic lines in the inboard wing leading edge. This chafing can lead to complete hydraulic failure due to loss of fluid, making it imperative for the specified aircraft to adhere to this directive.
In terms of obligations, the affected operators and owners of the Jetstream Series 3100 aircraft must ensure that the specified modifications or inspections are carried out within 300 flying hours from 31 August 1985. The directive mandates that these modifications or inspections must be carried out in accordance with the requirements set forth in the referenced British Aerospace Service Bulletin. Failure to comply with these requirements may result in the aircraft being deemed unairworthy, which could lead to grounding of the aircraft and potential legal ramifications.
The consequences for non-compliance with the AD/JETSTREAM/6 directive are significant. Operators who fail to comply with the directive risk facing substantial penalties. Under the Civil Aviation Act 1988, the penalties for non-compliance with airworthiness directives can include fines and, in severe cases, imprisonment. The specific penalties can vary depending on the severity of the breach and the impact on aviation safety. CASA has the authority to take enforcement actions, including issuing enforcement notices, conducting inspections, and pursuing legal action against non-compliant operators. It is crucial for operators to adhere strictly to the directive to avoid these severe consequences.
