COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
British Aerospace BAe 125 Series Aeroplanes
AD/HS 125/129
Amdt 1
Marking of Windshield Heat Power Supply Circuit Breakers
5/98
Applicability: All model 125 series 800A and 800B aeroplanes.
Requirement: Unless previously accomplished, incorporate “smoke drill indicator labels” in accordance with British Aerospace Service Bulletin SB.24-288-3284A dated 7 February 1992.
Note: CAA(UK) AD 016-02-92 refers.
Compliance: The compliance remains unchanged as “As specified in the Requirements Document with a revised effective date of 31 July 1992”.
This amendment becomes effective on 23 April 1998.
Background: This directive requires the incorporation of a modification that allows ready identification of additional circuit breakers to be included in ‘smoke drill procedures’.
This directive has been reissued at amendment 1 following the return of a BAe 125 Series 800 aeroplane to the Australian register and effectively remains unchanged, containing some minor additions such as referencing the CAA(UK) airworthiness directive and identifying the service bulletin.
The original issue of this airworthiness directive became effective on 31 July 1992.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). The ADs aim to ensure that civil aircraft remain in a safe and airworthy condition throughout their operation. AD/HS 125/129 Amendment 1, issued on 5 September 1998, addresses the marking of windshield heat power supply circuit breakers for British Aerospace BAe 125 Series Aeroplanes, models 125 series 800A and 800B. This directive, which applies to aircraft registered in Australia, requires the incorporation of "smoke drill indicator labels" in accordance with British Aerospace Service Bulletin SB.24-288-3284A dated 7 February 1992, to facilitate the inclusion of additional circuit breakers in smoke drill procedures. The amendment became effective on 23 April 1998, following the return of a BAe 125 Series 800 aeroplane to the Australian register. This reissue effectively maintains the original directive's requirements with minor additions, such as referencing the UK Civil Aviation Authority (CAA) airworthiness directive and identifying the service bulletin. The primary objective of this directive is to enhance the safety and operational readiness of these aircraft by ensuring clear identification of critical components during emergency procedures.
Scope and Application
The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically Part 39 - 105, pertains to the British Aerospace BAe 125 Series Aeroplanes and mandates certain modifications to ensure airworthiness. This particular directive, AD/HS 125/129 Amendment 1, applies to all model 125 series 800A and 800B aeroplanes. Its primary requirement is the incorporation of “smoke drill indicator labels” in accordance with British Aerospace Service Bulletin SB.24-288-3284A dated 7 February 1992. This modification is intended to facilitate the identification of additional circuit breakers in smoke drill procedures, enhancing safety and operational efficiency. Compliance with this directive is contingent upon adhering to the specifications outlined in the Requirements Document, with an effective date of 31 July 1992. The amendment took effect on 23 April 1998, and it references the CAA(UK) airworthiness directive and the associated service bulletin. This legislative instrument ensures that all specified aircraft within its scope meet stringent safety standards set forth by the Civil Aviation Safety Authority.
Key Provisions
The primary operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for British Aerospace BAe 125 Series Aeroplanes, mandate certain actions regarding the marking of windshield heat power supply circuit breakers (section 1). For model 125 series 800A and 800B aeroplanes, this directive requires the incorporation of "smoke drill indicator labels" as per British Aerospace Service Bulletin SB.24-288-3284A dated 7 February 1992 (section 2). The directive was originally issued on 31 July 1992, and it was reissued as Amendment 1 on 23 April 1998, with minor additions to reference the CAA(UK) airworthiness directive and identify the service bulletin (section 3). Compliance with these requirements is stipulated to be as specified in the Requirements Document, with a revised effective date of 31 July 1992 (section 4).
Entities governed by these regulations are required to ensure that all model 125 series 800A and 800B aeroplanes comply with the marking of windshield heat power supply circuit breakers as specified. This involves incorporating the "smoke drill indicator labels" as outlined in the referenced service bulletin and adhering to the compliance requirements noted in the directive. The obligations extend to maintaining awareness of the amended effective date and ensuring that the modifications are completed unless they have already been accomplished (section 5).
Breach of these obligations may lead to various consequences, though specific details of penalties or civil/criminal consequences are not provided in the directive. However, given the nature of aviation safety regulations, non-compliance could result in severe repercussions, potentially including fines, grounding of the aircraft, or other enforcement actions by CASA. The exact penalties would depend on the severity of the breach and the specific regulatory framework governing such actions at the time of the violation (section 6).
