AD/HS 125/99 - Stall Warning Vane

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), are comprehensive rules governing civil aviation in Australia. One of the key instruments under this regulation is the Schedule of Airworthiness Directives, which ensures that aircraft meet specific safety standards. The directive F2006B10542, specifically AD/HS 125/99, was enacted to address issues pertaining to the stall warning vane in British Aerospace BAe 125 Series Aeroplanes. This legislation was introduced to fill a gap in the existing regulatory framework by mandating specific actions to rectify or mitigate safety risks associated with the stall warning vane. The overarching policy objective of this directive, as outlined in the Civil Aviation Regulations 1998, is to maintain and enhance the safety of civil aviation in Australia.

Scope and Application

The Civil Aviation Safety Authority (CASA) administers the Civil Aviation Regulations 1998, which include specific directives for the maintenance and operation of aircraft, such as the Airworthiness Directives (AD) concerning various aircraft models. One such AD, AD/HS 125/99, initially targeted the British Aerospace BAe 125 series aeroplanes, mandating specific maintenance requirements for the stall warning vane. However, it is pertinent to note that this particular AD has been removed from the current listing as the referenced aircraft model is no longer on the Australian aircraft register. This indicates that the AD specifically applies to operators and maintainers of the BAe 125 series aeroplanes within the Commonwealth of Australia. The geographic reach of these regulations is national, applying uniformly across all states and territories. Any exclusions or exemptions from these directives would typically be outlined within the regulations themselves or in related CASA guidance documents, and any updates or extensions to the application of these regulations may be made through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, Section 105, detail specific requirements for the airworthiness of British Aerospace BAe 125 Series Aeroplanes. One such directive, AD/HS 125/99, pertains to the stall warning vane. However, it is noted that this directive has been removed from the listing as the aircraft model in question is not currently registered (AD/HS 125/99). This implies that any requirements previously outlined for this particular model and component are no longer applicable. The obligations imposed by the Civil Aviation Regulations 1998 on parties and entities, including aircraft manufacturers, operators, and maintenance providers, are comprehensive. They must ensure that all aircraft remain airworthy by adhering to the stipulated directives and safety standards. This involves conducting regular inspections, maintenance, and modifications as required by the Civil Aviation Safety Authority (CASA). Operators and maintenance providers must keep detailed records of all actions taken in compliance with these regulations, ensuring that all aircraft meet the necessary safety criteria before operation. Failure to comply with the Civil Aviation Regulations 1998 can result in significant consequences. Offences under these regulations may lead to both civil and criminal penalties. For instance, an operator failing to adhere to an airworthiness directive could face substantial fines or even imprisonment, depending on the severity of the breach. Civil penalties could include monetary fines, suspension or revocation of aircraft certificates, and operational restrictions. The exact penalties are dictated by the specific nature of the offence and are enforced by CASA, ensuring that all parties maintain the highest standards of aviation safety.
