Overview
The Civil Aviation Regulations 1998, as amended, form a critical part of Australia's regulatory framework governing civil aviation safety. One specific legislative instrument within this body of regulations, F2006B06949, focuses on issuing airworthiness directives for the Saab SF340 Series aeroplanes, particularly addressing autopilot wiring issues identified in earlier models. Enacted by the Australian Government, this directive aims to ensure that specific modifications are made to the wiring systems of these aircraft to prevent potential safety hazards. The objective is to maintain compliance with international safety standards, specifically referencing Swedish AD 1-041, to ensure the correct circuit coordination and overall airworthiness of the affected aircraft.
This legislative instrument is an integral part of the Civil Aviation Safety Authority's (CASA) mandate to regulate and enforce safety standards within the aviation industry. By issuing this airworthiness directive, CASA addresses a specific problem identified with the autopilot wiring in certain Saab SF340 models, ensuring that these aircraft meet the necessary safety criteria before they can be operated. The directive mandates that wire FD 574-24 be replaced with a 20 AWG sized wire to rectify the identified issue, thereby safeguarding the integrity of the aircraft's autopilot system and ensuring the safety of all passengers and crew on board.
Scope and Application
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, focusing on the Saab SF340 series aeroplanes. This legislative instrument applies to the Saab SF340A with serial numbers ranging from 079 to 159 and the Saab SF340B with serial numbers from 160 to 199, mandating modifications to the autopilot wiring. The directive is necessary to ensure compliance with safety standards set forth by the Swedish aviation authorities, requiring the replacement of the wire FD 574-24 with a 20 AWG sized wire to maintain correct circuit coordination. This regulation extends throughout the Commonwealth of Australia and is enforceable by CASA. The directive does not specify any exclusions or exemptions but requires compliance prior to 1st June 1991. The scope of this directive is further extended and defined through subordinate instruments, which provide detailed procedural and compliance requirements.
Key Provisions
The main sections of the Civil Aviation Regulations 1998, Part 39 - 105, relevant to this legislative instrument, are those that detail the applicability and compliance requirements for the SAAB SF340 Series Aeroplanes, specifically addressing autopilot wiring as outlined in AD/SF340/20. Section 39-105 (2) requires that modifications to the autopilot wiring of SAAB SF340A and SAAB SF340B series aeroplanes be made in accordance with the Swedish Air Force (LFV) AD 1-041. This directive applies to SAAB SF340A serial numbers 079 through 159 and SAAB SF340B serial numbers 160 through 199. The key requirement is to replace Wire FD 574-24 with a 20 AWG sized wire to ensure correct circuit coordination is maintained, as per SAAB-SCANIA SB SAAB 340-34-068.
The obligations and requirements imposed by this Act on the parties or entities it governs include ensuring that all modifications to the autopilot wiring of the specified SAAB SF340 series aeroplanes are carried out in strict adherence to the directives provided by LFV AD 1-041. This includes the replacement of Wire FD 574-24 with a 20 AWG sized wire, which is critical for maintaining the integrity and safety of the aircraft's autopilot system. Compliance with these directives must be achieved before 1st June 1991, as stated in the note section.
Any failure to comply with the requirements set out in AD/SF340/20 could result in serious safety implications, potentially leading to operational and legal repercussions. The regulations do not explicitly detail specific offences, penalties, or civil/criminal consequences in this legislative instrument. However, non-compliance with Civil Aviation Regulations is generally subject to enforcement actions by the Civil Aviation Safety Authority (CASA), which can include fines, suspension of airworthiness certificates, or other regulatory actions to ensure adherence to aviation safety standards.
