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 125/148 Electrical Power Diode Connections 4/95
Applicability: BAe 125 Series 800A & B, 1000A & B, Hawker 800 and 1000 aircraft identified in Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB 24-317 dated
22 December 1994.
Requirement: Inspect the soldered diode connections on panels ZL (800 Series) or ZK (1000 Series) for integrity of the soldered joint and if necessary, resolder any unacceptable connections in accordance with the Accomplishment Instructions of Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB 24-317 dated 22 December 1994.
Note: This Service Bulletin has been classified as Mandatory by the CAA(UK).
Compliance: Prior to 31 August 1995.
Background: Hawker Raytheon has received reports of imperfect soldered connections in the engine starting and battery emergency control circuits, which have led to intermittent fault symptoms in these systems. Compliance with this Directive is designed to eliminate these intermittent fault systems. The CAA(UK) compliance date is extended by one calendar month for Australian registered aircraft.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address various safety and operational standards for civil aviation within the country. One specific piece of legislation is Part 39 - 105, concerning the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. This particular entry, AD/HS 125/148, pertains to the British Aerospace BAe 125 Series Aeroplanes and focuses on the integrity of electrical power diode connections. This directive was introduced to rectify issues identified in the BAe 125 Series 800A & B, 1000A & B, Hawker 800, and 1000 aircraft. The problem it addresses is the presence of imperfect soldered connections in the engine starting and battery emergency control circuits, which have caused intermittent fault symptoms in these systems. The policy objective of this directive is to ensure the safety and reliability of these aircraft by mandating inspections and necessary repairs, thus mitigating potential safety risks.
Scope and Application
The Civil Aviation Regulations 1998, under the legislative instrument F2006B10428, specifically address the maintenance and safety requirements for the BAe 125 Series aeroplanes, including the 800A & B, 1000A & B, and Hawker 800 and 1000 aircraft. This legislation applies to any aircraft identified in Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB 24-317 dated 22 December 1994. The requirement outlined in the legislation is to inspect the soldered diode connections on panels ZL (800 Series) or ZK (1000 Series) to ensure the integrity of the soldered joint, and to resolder any unacceptable connections as per the Accomplishment Instructions of the aforementioned service bulletin. The directive is designed to address reported issues with imperfect soldered connections in the engine starting and battery emergency control circuits, which have caused intermittent fault symptoms. Compliance with this directive is mandatory and must be completed prior to 31 August 1995, although the compliance date for Australian registered aircraft is extended by one calendar month.
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, contain detailed provisions regarding the safety of British Aerospace BAe 125 Series aeroplanes. Section AD/HS 125/148 mandates an inspection of the soldered diode connections on panels ZL (for the 800 Series) or ZK (for the 1000 Series) to ensure the integrity of the soldered joints. If any connections are found to be unacceptable, they must be resoldered in accordance with the Accomplishment Instructions provided in Hawker Raytheon Corporate Jets Mandatory Service Bulletin SB 24-317 dated 22 December 1994. This directive applies to BAe 125 Series 800A & B, 1000A & B, Hawker 800, and 1000 aircraft identified in the aforementioned service bulletin.
The obligations imposed by this legislation on the operators and owners of the specified aircraft include a thorough inspection of the mentioned electrical connections and corrective actions as required. Operators must ensure that all inspections and repairs are carried out before the compliance date of 31 August 1995. This requirement is to address the reports of imperfect soldered connections in the engine starting and battery emergency control circuits, which have caused intermittent faults in these systems. The directive aims to eliminate these issues to maintain the safety and reliability of the aircraft.
Failure to comply with the provisions set out in this Airworthiness Directive may lead to serious safety implications. The Australian Civil Aviation Safety Authority (CASA) takes a stringent stance on such compliance to ensure the highest safety standards. Any non-compliance could potentially result in civil or criminal consequences. Although the specific penalties are not detailed in this particular directive, under the broader Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to significant fines and potential prosecution for individuals and corporations responsible for the aircraft. The maximum penalties could include fines up to several thousand Australian dollars and imprisonment for directors found guilty of negligence or failure to ensure compliance.
