AD/JETSTREAM/12 - D.C. Power Distribution System

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, address the need for maintaining airworthiness standards for aircraft operating in Australia. This regulation was enacted to ensure that all aircraft meet the necessary safety standards and comply with international regulations. The Australian Government, through the Civil Aviation Safety Authority, established this schedule of airworthiness directives to maintain safety and operational standards in the aviation industry. The policy objective behind these regulations is to protect public safety by enforcing compliance with airworthiness directives that are essential for the safe operation of aircraft. One such directive, AD/JETSTREAM/12, pertains to the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, focusing on the D.C. Power Distribution System. This directive applies to Jetstream Series 3100 aircraft with serial numbers ranging from 601 through 659. The requirement, as outlined in British Aerospace Service Bulletin 24-A-JA850648, is classified as mandatory by the British Civil Aviation Authority. The directive mandates compliance within 200 hours of time in service after 30 November 1985, addressing a specific concern about insufficient clearance between components at Station 130 on the right-hand bulkhead. This measure ensures that the area is inspected and modified as necessary, thereby maintaining the safety and airworthiness of the aircraft in accordance with the established regulatory standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's schedule of airworthiness directives which apply to certain aircraft within the Commonwealth of Australia. This particular directive, AD/JETSTREAM/12, focuses on the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, specifically those with serial numbers ranging from 601 to 659. The regulation mandates compliance with British Aerospace Service Bulletin 24-A-JA850648, which has been classified as mandatory by the British Civil Aviation Authority. Compliance with this directive requires inspection and modification of the D.C. power distribution system as per the service bulletin, to be completed within 200 hours of time in service following 30 November 1985, addressing potential clearance issues between components at Station 130 on the right-hand bulkhead. This legislative instrument is instrumental in ensuring the safety and airworthiness of specified aircraft within the Australian aviation sector, thereby governing the conduct and maintenance practices applicable to these aircraft.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, mandates the applicability and compliance requirements for Jetstream Series 3100 aircraft with serial numbers (S/Nos.) 601 through 659. The primary focus of this regulation is the power distribution system of these aircraft, as outlined in Airworthiness Directive AD/JETSTREAM/12. The directive stipulates that these aircraft must adhere to British Aerospace Service Bulletin 24-A-JA850648, which has been classified as mandatory by the British Civil Aviation Authority. The key requirement is to ensure that the clearance between components mounted at Station 130 on the right-hand bulkhead is sufficient. Compliance with this directive must be achieved within 200 hours of time in service after 30 November 1985. The Act imposes specific obligations on the owners and operators of Jetstream Series 3100 aircraft with the specified serial numbers. These obligations include conducting a thorough inspection of the components at Station 130 on the right-hand bulkhead to ascertain whether the clearance between the components is adequate. If the inspection reveals insufficient clearance, the aircraft must be modified in accordance with the instructions provided in the referenced Service Bulletin. Additionally, the modifications must be completed within the prescribed timeframe to ensure continued airworthiness and compliance with the regulations. Failure to comply with the requirements set out in the Airworthiness Directive AD/JETSTREAM/12 can result in serious legal and safety consequences. The Civil Aviation Regulations 1998 outline potential civil and criminal penalties for non-compliance. For instance, operating an aircraft that does not meet the airworthiness standards could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Depending on the severity and circumstances of the non-compliance, penalties may include fines, suspension or revocation of the aircraft's certificate of airworthiness, or even criminal charges against the operator. In extreme cases, the maximum penalties can be substantial, reflecting the critical nature of maintaining aircraft safety and airworthiness standards.
