Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, encompasses the legislative framework within which the Civil Aviation Safety Authority (CASA) issues airworthiness directives. The directive AD/JETSTREAM/2, enacted to address the problem of induced vibrations in Jetstream Series 3100 aircraft (constructors numbers 601 to 645) during icing conditions at low ambient temperatures, was introduced to ensure safety and operational reliability of these aircraft. This directive mandates compliance with Service Bulletin 30-JM7453 Revision 1 before any further flight after 31 May 1985, aiming to mitigate risks associated with propeller ice and rain protection. This legislative instrument was enacted by the Australian Government to establish critical safety standards and compliance measures for aircraft operating within Australian airspace. The policy objective behind this directive is to ensure that aircraft meet the necessary safety criteria, thereby protecting passengers, crew, and the general public from potential hazards associated with inadequate ice and rain protection systems on propellers. The directive reflects CASA's commitment to maintaining high safety standards in the aviation industry by ensuring that aircraft modifications and maintenance adhere to rigorous safety protocols.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to the Jetstream Series 3100 aircraft with constructors' numbers ranging from 601 to 645. This legislation is part of the broader regulatory framework overseen by the Civil Aviation Safety Authority (CASA) and pertains specifically to the safety modifications required for the Jetstream 3100 aeroplanes to ensure they remain airworthy. The regulation mandates compliance with Service Bulletin 30-JM7453 Revision 1, which addresses propeller ice and rain protection, to be implemented before any further flight after 31 May 1985. This directive aims to mitigate issues such as induced vibrations during icing conditions at low ambient temperatures, ensuring the operational safety of these aircraft. The regulations apply on a national level, enforcing compliance across all states and territories within Australia. There are no exclusions or exemptions specified within the text, and the scope is strictly limited to the mentioned aircraft models and their modifications.

Key Provisions

The key sections of this legislation pertain to the applicability of the Airworthiness Directives (ADs) for the Jetstream Series 3100 aircraft (section 1). This directive applies to aircraft with constructors' numbers ranging from 601 to 645 (section 2). It mandates compliance with Service Bulletin 30-JM7453 Revision 1, which outlines the modifications required to address the issues of induced vibrations during icing conditions at low ambient temperatures (section 3). The directive stipulates that these modifications must be completed before any further flight after 31 May 1985 (section 4). The obligations imposed by this Act require the operators of Jetstream Series 3100 aircraft to ensure that the specified propeller de-icing system modifications are implemented. This involves adhering to the guidelines set forth in Service Bulletin 30-JM7453 Revision 1 and ensuring that all modifications are completed before any subsequent flight. The compliance date of 31 May 1985 sets a clear deadline for these modifications to be carried out, underscoring the importance of timely action to maintain the airworthiness of the aircraft. Breach of the requirements outlined in this Airworthiness Directive can lead to serious consequences. While the specific penalties are not detailed within the text, it is understood that non-compliance with ADs can result in severe regulatory action under the Civil Aviation Act 1988. Such actions may include fines, suspension of airworthiness certificates, or other enforcement measures that can significantly impact the operation of the affected aircraft. Given the potential safety implications of ignoring these directives, operators must take the requirements seriously and ensure full compliance to avoid these repercussions.
