Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the issue of ensuring the airworthiness of British Aerospace BAe 125 series aeroplanes through Airworthiness Directives. This legislation was enacted by the Commonwealth of Australia to provide a regulatory framework for maintaining the safety standards of civil aviation, including specific directives for particular aircraft models. In this instance, the Civil Aviation Safety Authority has issued AD/HS 125/70 to address a critical issue identified by the aircraft manufacturer concerning the EFIS power supply overheating. The directive requires the modification of the EFIS power supply in specified BAe 125 series aeroplanes to mitigate the risk of overheating, ensuring continued compliance with safety standards and protecting the safety of all individuals on board.
The objective of this legislation, as stated in the Civil Aviation Regulations 1998, is to safeguard the airworthiness of specified aircraft by implementing necessary modifications to prevent overheating of the heat sink diode assembly. The directive mandates compliance by a specific date, highlighting the urgency and importance of addressing the identified safety issue. By enforcing this directive, the Civil Aviation Safety Authority aims to uphold the highest standards of aviation safety, ensuring that aircraft meet the necessary safety requirements before the specified compliance date.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, mandates the modification of the EFIS power supply for certain British Aerospace BAe 125 series aeroplanes. This directive applies to all BAe-125 series aeroplanes with specific serial numbers: Series 700B aeroplanes numbered 257208 to 257210, 257214, and 257215, and Series 800A and B aeroplanes numbered 258001 to 258020, 258022 to 258024, and 258026. The requirement to modify the EFIS power supply must adhere to the specifications detailed in British Aerospace 125 S.B. 24-248-(3024), referencing United Kingdom CAA AD No. 004-04-85. Compliance with these directives is mandatory, and modifications must be completed before 31 October 1985. The directive applies nationally across Australia and is enforced by CASA to ensure safety and compliance within the aviation industry.
Key Provisions
The Civil Aviation Regulations 1998 (sections 39-105) contain specific provisions for maintaining the airworthiness of British Aerospace BAe 125 Series aeroplanes. Specifically, AD/HS 125/70 mandates modifications to the EFIS power supply for certain serial numbers of BAe-125 series aeroplanes. The relevant serial numbers are 700B - 257208 to 257210, 257214, and 257215 for Series 700B, and 800A and B - 258001 to 258020, 258022 to 258024, and 258026 for Series 800A and B. The requirement is to modify the EFIS power supply in accordance with British Aerospace 125 S.B. 24-248-(3024), with reference to United Kingdom CAA AD No. 004-04-85. The modifications must be completed before 31 October 1985, following an incident where the heat sink diode assembly overheated on a completed aircraft.
Entities governed by these regulations, particularly aircraft operators and maintenance service providers, must ensure that the specified modifications are carried out on the listed BAe-125 series aeroplanes. This includes adherence to the detailed instructions provided in British Aerospace 125 S.B. 24-248-(3024), ensuring that the EFIS power supply is updated to mitigate the risk of overheating. Failure to comply with these directives may result in non-compliance with airworthiness standards, potentially leading to serious safety issues.
Failure to comply with these airworthiness directives can result in significant consequences. The Civil Aviation Regulations 1998 impose obligations on operators and maintenance providers to ensure that modifications are completed in a timely and effective manner. If these directives are not met, the aeroplanes may be deemed non-airworthy, which can result in grounding and potential legal action. The severity of the consequences underscores the importance of adhering to the specified deadlines and modification requirements.
In terms of penalties and consequences for non-compliance, while the specific maximum penalties are not detailed within the provided text, breaches of airworthiness directives can lead to severe repercussions. This can include substantial fines, operational restrictions, and potentially criminal charges against individuals or corporate entities responsible for the non-compliance. Such outcomes underscore the critical nature of adhering to the Civil Aviation Regulations 1998 to ensure the safety and airworthiness of the aircraft in question.
