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 125/155 Fuselage Fluid Drainage 10/96
Applicability: BAe 125 series 800A, series 800B, and Hawker 800 aircraft.
Requirement: Action in accordance with Hawker Mandatory Service Bulletin 53-82-3566G Revision 3.
Note: FAA AD 96-12-16 Amdt 39-9659 refers.
Compliance: Unless Modification 253566G is already installed in accordance with a previous issue of the Requirement document, including a functional test to determine if a bolt fouls the flap control system (in accordance with para. 2.A.(18) of the SB Accomplishment Instructions); before 31 December 1996.
Background: Reports were received of restricted control of the ailerons due to water accumulation that froze at an aileron pulley in the lower area of the fuselage, aft of the wing rear spar.
Overview
The Civil Aviation Regulations 1998 (Cth) are a comprehensive set of regulations designed to ensure the safety of civil aviation within Australia, as overseen by the Civil Aviation Safety Authority. Specifically, Part 39 - 105 includes the Airworthiness Directives which mandate corrective actions and compliance for certain aircraft types to ensure they meet the required safety standards. The legislative instrument F2006B10436, pertaining to the British Aerospace BAe 125 Series Aeroplanes, was introduced to address the issue of restricted control of the ailerons due to water accumulation that could freeze at an aileron pulley in the lower area of the fuselage, aft of the wing rear spar. The policy objective was to mitigate the safety risks associated with this issue by requiring corrective action as outlined in Hawker Mandatory Service Bulletin 53-82-3566G Revision 3.
The Australian Government, through the Civil Aviation Safety Authority, enacted these regulations to ensure that the BAe 125 series 800A, series 800B, and Hawker 800 aircraft meet the necessary safety requirements. This was achieved through the issuing of Airworthiness Directives that required specific actions to be taken by aircraft operators to address the identified safety issues. The directive references FAA AD 96-12-16 Amdt 39-9659, indicating a collaborative approach with international aviation authorities to uphold safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the safety directives for the British Aerospace BAe 125 series aeroplanes, targeting the BAe 125 series 800A, series 800B, and Hawker 800 aircraft. This regulation mandates that these aircraft must comply with the Hawker Mandatory Service Bulletin 53-82-3566G Revision 3 concerning fuselage fluid drainage. The directive applies to all such aircraft and requires adherence to the specified modifications and functional testing to prevent restricted control of the ailerons caused by water accumulation and freezing. Compliance with these directives is mandatory unless the aircraft have already had the specified modification installed under a prior requirement, with the compliance deadline set as 31 December 1996. This regulation extends its jurisdictional reach across the Commonwealth of Australia, enforced by the Civil Aviation Safety Authority.
The scope of the Civil Aviation Regulations 1998 is limited to the specified BAe 125 series aeroplanes and excludes other types of aircraft not listed in the directive. The regulation does not explicitly state any exclusions or exemptions, thereby imposing a universal requirement for the specified aircraft within its jurisdiction. The regulation’s application is reinforced by the authority’s power to extend or restrict its application through subordinate instruments, ensuring the safety and compliance of the specified aircraft within the Australian aviation sector.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety of British Aerospace BAe 125 Series Aeroplanes, with a focus on fuselage fluid drainage as outlined in AD/HS 125/155 F. This legislation applies to BAe 125 series 800A, series 800B, and Hawker 800 aircraft. The main requirement is that these aircraft must adhere to the actions specified in Hawker Mandatory Service Bulletin 53-82-3566G Revision 3. This service bulletin, in turn, refers to FAA AD 96-12-16 Amdt 39-9659 for further guidance. The primary directive is that, unless Modification 253566G has already been installed and tested as per the Service Bulletin's Accomplishment Instructions (para. 2.A.(18)), the compliance action must be completed before 31 December 1996.
The obligations imposed by this legislation on the operators of the BAe 125 series 800A, 800B, and Hawker 800 aircraft include ensuring that they either already have the Modification 253566G installed or they must undertake the installation and functional testing to ascertain that a bolt does not interfere with the flap control system. This requirement ensures the aircraft's safety by preventing water accumulation that could freeze and lead to restricted control of the ailerons, as evidenced by past reports of such occurrences. The installation must be carried out in accordance with the instructions provided in the Hawker Mandatory Service Bulletin 53-82-3566G Revision 3, which includes the specified timeline for compliance.
In the event that an operator fails to comply with the requirements stipulated in the Civil Aviation Regulations, there are potential consequences. The specific civil and criminal penalties for non-compliance with these regulations are not detailed in the legislative text provided; however, under general civil aviation law, breaches can result in severe penalties. These may include substantial fines and, in some cases, the grounding of the aircraft until compliance is achieved. The severity of the penalties is commensurate with the level of risk posed by the non-compliance to aviation safety.
