COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Short SD3-60 Series Aeroplanes
AD/SD3-60/59 Electrical Wiring and Hydraulic Pipelines 7/2001
Applicability: All SD3-60 aeroplanes.
Requirement: 1. Inspect electrical wiring harnesses and the hydraulic pipelines servicing the 7P panel for fouling and, if necessary, re-route the wiring harnesses, install additionally supporting clips and sleeving in accordance with Bombardier Aerospace, Short Brothers PLC Service Bulletin (SB) SD360-24-25 dated 30 April 2001.
2. If adequate clearance between the harnesses and the main pressure hydraulic pipeline cannot be achieved during the Requirement 1 re-routing of the electrical wiring harnesses, replace the pipeline with new rerouted pipeline in accordance with SB SD360-24-25.
Note: This Service Bulletin has been classified as mandatory by the CAA(UK).
Compliance: For Requirement 1 – At the next ‘B’ Check, but no later than 90 days after the effective date of this Directive.
For Requirement 2 – Before further flight, after completion of Requirement 1 This Airworthiness Directive becomes effective on 12 July 2001.
Background: This Directive is intended to ensure that adequate clearance exists between electrical wiring and pipelines containing combustible fluids. These measures are designed to reduce the likelihood of fouling and/or chaffing, with the resultant risk of an in-flight fire.
Eugene Paul Holzapfel
Delegate of the Civil Aviation Safety Authority 28 May 2001
The above AD is notified in the Commonwealth of Australia Gazette on 13 June 2001.
Overview
The Civil Aviation Regulations 1998 were enacted to establish a comprehensive regulatory framework for civil aviation in Australia, ensuring safety and efficiency within the industry. This legislation is administered by the Civil Aviation Safety Authority (CASA) and was developed to address various gaps in aviation safety standards, ensuring compliance with international norms and maintaining public confidence in air travel. The Airworthiness Directive (AD) issued under the authority of the Civil Aviation Regulations 1998 specifically targets the safety of Short SD3-60 Series aeroplanes. The directive, which became effective on 12 July 2001, was introduced to address potential unsafe conditions concerning the electrical wiring and hydraulic pipelines of these aircraft. The policy objective of the AD is to mandate inspections and necessary repairs to prevent fouling and chafing, which could lead to in-flight fires, thereby ensuring the continued airworthiness and safety of the aircraft.
Scope and Application
This Airworthiness Directive, issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, applies specifically to all SD3-60 aeroplanes. The directive mandates the inspection and, if necessary, the re-routing of electrical wiring harnesses and the installation of additional supporting clips and sleeving to ensure adequate clearance between the wiring and hydraulic pipelines. Furthermore, if adequate clearance cannot be achieved through re-routing, the directive requires the replacement of the hydraulic pipelines as per the specifications detailed in the Bombardier Aerospace, Short Brothers PLC Service Bulletin SD360-24-25 dated 30 April 2001. Compliance with these requirements must occur at the next 'B' Check, with a maximum of 90 days from the directive's effective date of 12 July 2001, and before further flight if a pipeline replacement is necessary. This directive extends to all SD3-60 aeroplanes within the Commonwealth of Australia and has been classified as mandatory by the UK Civil Aviation Authority (CAA).
Key Provisions
The Civil Aviation Regulations 1998, specifically under PART 39 - 105 and the Schedule of Airworthiness Directives, establish a framework for maintaining aircraft safety. Section 39.1 (1) empowers the Civil Aviation Safety Authority (CASA) delegate to issue Airworthiness Directives (AD) that are binding on the relevant aircraft or aeronautical products. For instance, AD/SD3-60/59 (7/2001) pertains to all SD3-60 series aeroplanes and mandates specific actions to address identified safety concerns. The directive requires that electrical wiring harnesses and hydraulic pipelines servicing the 7P panel be inspected for fouling, with necessary re-routing, installation of supporting clips and sleeving, or replacement of the pipeline, as per the instructions detailed in Bombardier Aerospace, Short Brothers PLC Service Bulletin (SB) SD360-24-25 dated 30 April 2001.
The obligations imposed by this AD are clear and specific. Owners and operators of SD3-60 series aeroplanes must ensure that these inspections and repairs are conducted in accordance with the directive. For Requirement 1, the action must be completed at the next 'B' Check, but no later than 90 days after the effective date of the directive. For Requirement 2, if adequate clearance cannot be achieved, the hydraulic pipeline must be replaced before further flight, following the completion of Requirement 1. Failure to adhere to these requirements may compromise the safety of the aircraft and its occupants.
Non-compliance with the Airworthiness Directive can lead to significant legal and safety repercussions. The regulations do not explicitly detail the specific offences or penalties in this context, but the overarching Civil Aviation Act 1988 and Civil Aviation Regulations 1998 provide a framework for enforcement. Violators may face penalties including fines, imprisonment, or both, depending on the severity of the breach. The specific maximum penalties for non-compliance with ADs are not detailed in this particular directive but are generally severe, reflecting the critical importance of maintaining airworthiness standards.
