AD/JETSTREAM/45 Amdt 1 - Power Lever Control Cables

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, is a comprehensive piece of legislation aimed at ensuring the safety and efficiency of civil aviation within Australia. One specific aspect of this regulation is detailed in Part 39, which pertains to airworthiness directives for various aircraft, including the British Aerospace BAe 3100 (Jetstream) series. This legislative instrument addresses issues related to the safety of aircraft operation by mandating specific requirements and actions to be taken to mitigate identified risks. The underlying policy objective is to ensure that all civil aircraft operating within Australia meet the necessary safety standards to protect passengers, crew, and the public. This particular airworthiness directive, AD/JETSTREAM/45 Amendment 1, focuses on power lever control cables in certain Jetstream series aeroplanes, responding to reported failures and aligning with the manufacturer's recommendations to enhance safety. The directive requires compliance with specific British Aerospace Service Bulletins to address issues identified with the power lever control cables. It applies to all HP137 Mk1, Jetstream Series 200, Jetstream Series 3100, and Jetstream Series 3200 aircraft with constructors numbers 790 through 960. The directive mandates actions consistent with BAe Mandatory ASB 76-A-JA 910542 and notes that compliance with BAe SB 76-JA 911042 constitutes terminating action for this directive. The amendment was introduced to ensure that these aircraft meet safety standards, reflecting the Civil Aviation Safety Authority's commitment to maintaining high safety protocols in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives under the Civil Aviation Safety Authority (CASA) and applies to all persons involved in the operation and maintenance of aircraft within Australia. This regulation mandates compliance with specific airworthiness directives to ensure the safety of civil aviation operations. The scope of this particular directive, AD/JETSTREAM/45 Amendment 1, is limited to British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, namely the HP137 Mk1, Jetstream Series 200, Jetstream Series 3100, and Jetstream Series 3200 with constructors' numbers ranging from 790 to 960. The directive requires adherence to the BAe Mandatory ASB 76-A-JA 910542, with compliance until such time as BAe SB 76-JA 911042 is implemented, which then constitutes the terminating action for this directive. This amendment was made effective from 2 March 1995 in response to reported failures of the power lever control cable during engine ground runs, as determined by the UK Civil Aviation Authority. The regulation extends to ensuring that all relevant aircraft meet the specified safety requirements to maintain airworthiness standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which includes AD/JETSTREAM/45 Amendment 1. This amendment pertains to the power lever control cables of certain British Aerospace BAe 3100 (Jetstream) Series aeroplanes (section 39-105). The directive applies to all HP137 Mk1, Jetstream Series 200, Jetstream Series 3100, and Jetstream Series 3200 with constructors numbers ranging from 790 through 960. The directive requires compliance with BAe Mandatory ASB 76-A-JA 910542, with an allowance for BAe SB 76-JA 911042 as terminating action for the requirement of this directive. Compliance must be achieved as specified in the requirement document, with this amendment being effective from 2 March 1995. The obligations imposed by this directive are clear and specific. Operators of the aforementioned aircraft models must ensure that their power lever control cables meet the specified requirements to maintain airworthiness. This involves following the mandatory action stipulated by BAe Mandatory ASB 76-A-JA 910542, which is intended to address the issue of cable failures reported during engine ground runs. Operators must take action to comply with these specifications to ensure the safety of their aircraft operations. The directive's applicability and the requirement for compliance are designed to mitigate risks associated with the identified safety issue. Failure to comply with the provisions of AD/JETSTREAM/45 Amendment 1 can result in severe consequences. The regulations underscore the importance of adhering to airworthiness directives to maintain the safety of aircraft operations. Non-compliance may lead to enforcement actions by CASA, which could include fines, suspension or revocation of airworthiness certificates, and other regulatory penalties. The maximum penalties for breaches of these regulations can be substantial, reflecting the critical nature of ensuring aircraft safety. Operators are therefore required to take prompt and effective action to ensure their aircraft meet the specified airworthiness standards to avoid these potential repercussions.
