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 125/149 Ice Protection Metering Pumps Wiring 5/95
DM
Applicability: BAe 125 Series 800A, Series 800B, Series 1000A, Series 1000B, Hawker 800 and Hawker 1000 aircraft.
Requirement: Action in accordance with Aerospace Systems and Technologies Ltd Mandatory Service Bulletin S.B.30-25 dated 27 January 1995 (Hawker Raytheon Corporate Jets Service Bulletin SB.30-61-7676A dated 15 February 1995 also refers).
Note: Aerospace Systems and Technologies Service Ltd Bulletin S.B.30-25 has been classified as Mandatory by the CAA (UK).
Compliance: Prior to 30 June 1995 for installed pumps or prior to being fitted to an aircraft for spare pumps.
Background: Aerospace Systems and Technologies has advised that ignition may occur when bare or defectively insulated silver plated wire carrying direct current is exposed to glycol. To avoid this risk, this Directive requires that wire with silver plated conductors is removed from the flying leads of the ice protection system metering pumps. The CAA (UK) compliance date is extended by one calendar month for Australian registered aircraft.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government, are instrumental in maintaining air safety standards. One legislative instrument under these regulations is the AD/HS 125/149 concerning British Aerospace BAe 125 Series aeroplanes, specifically addressing ice protection metering pumps wiring. This directive was introduced to mitigate the risk of ignition caused by bare or defectively insulated silver-plated wires in the ice protection system metering pumps, which can be exposed to glycol. The Civil Aviation Safety Authority (CASA) has classified the relevant service bulletin as mandatory, underscoring the urgency and necessity of this directive. The objective is to ensure the safe operation of BAe 125 Series aircraft by mandating compliance with specific wiring standards to prevent potential hazards.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, specifically addresses the airworthiness directives for certain British Aerospace BAe 125 Series aeroplanes, including the Series 800A, Series 800B, Series 1000A, Series 1000B, as well as the Hawker 800 and Hawker 1000 aircraft. This legislation mandates compliance with the requirements outlined in Aerospace Systems and Technologies Ltd Mandatory Service Bulletin S.B.30-25 dated 27 January 1995, which has been recognised by the UK's Civil Aviation Authority (CAA). The directive necessitates that any installed ice protection metering pumps comply with the specified wiring modifications prior to 30 June 1995, or for any spare pumps prior to their installation on an aircraft. This directive extends the compliance period by one calendar month for aircraft registered in Australia. The legislation applies nationally within the Commonwealth of Australia, with its enforcement overseen by the Civil Aviation Safety Authority. There are no exclusions, exemptions, or thresholds specified in the text, and its application may be further detailed or modified through subordinate instruments as deemed necessary by the relevant authorities.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, contain the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. This section details the requirements for maintaining the airworthiness of British Aerospace BAe 125 Series aeroplanes. The AD/HS 125/149 Airworthiness Directive pertains to the ice protection metering pumps wiring, as outlined in section 5/95DM. This directive applies to BAe 125 Series 800A, 800B, 1000A, 1000B, Hawker 800 and Hawker 1000 aircraft.
The key requirement of this directive, as stated in the legislation, is to follow the Aerospace Systems and Technologies Ltd Mandatory Service Bulletin S.B.30-25 dated 27 January 1995, and the Hawker Raytheon Corporate Jets Service Bulletin SB.30-61-7676A dated 15 February 1995. This action is necessitated by the risk of ignition when bare or defectively insulated silver-plated wire carrying direct current is exposed to glycol. Therefore, it is mandated that any wire with silver-plated conductors be removed from the flying leads of the ice protection system metering pumps. The directive requires compliance before 30 June 1995 for installed pumps, or before fitting spare pumps to an aircraft. It should be noted that the UK Civil Aviation Authority (CAA) has classified Aerospace Systems and Technologies Service Ltd Bulletin S.B.30-25 as Mandatory, and CASA has extended the compliance date by one calendar month for Australian registered aircraft.
Under these regulations, the entities governed must ensure they adhere to the specified service bulletins and remove the silver-plated conductors from the ice protection metering pumps wiring as instructed. This involves identifying the relevant wiring, removing it, and ensuring that the aircraft meets the airworthiness standards set by CASA. Failure to comply with these directives can have serious implications for the safety and airworthiness of the aircraft.
In terms of consequences, any breach of these requirements can lead to serious penalties. While the specific penalties are not detailed in the excerpt, breaches of Civil Aviation Regulations generally can result in both civil and criminal consequences. Civil penalties may include fines, and in severe cases, criminal penalties may apply, including imprisonment. The exact penalties can vary depending on the severity and nature of the breach but are designed to enforce compliance with safety regulations to ensure the highest standards of airworthiness are maintained.
