COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
SAAB SF340 Series Aeroplanes
AD/SF340/51 Engine Nacelle Fire Extinguisher Wiring 3/96
Applicability: This Directive is applicable to Model SF 340A aeroplanes serial numbers SF340-004 through -159 inclusive and Model 340B aeroplanes serial numbers 340B-160 through
-345 inclusive.
Requirement: Inspect and modify the engine nacelle fire extinguisher wiring in accordance with SAAB Aircraft AB Service Bulletin SAAB 340-26-015 dated 23 November 1995.
Note: Swedish (LFV) SAD 1-079 refers.
Compliance: No later than the next 4000 flight hour inspection (C check) after 29 February 1996.
Background: This Directive supersedes AD/SF340/39. SAAB Aircraft AB have advised that the possibility still exists for incorrect connection of the nacelle fire extinguishers despite incorporation of the modification required by AD/SF340/39. The actions required by this Directive are designed to ensure that the possibility of incorrect installation of fire extinguisher electrical wiring connections is minimised.
Overview
The Civil Aviation Regulations 1998 were enacted to regulate civil aviation in Australia, ensuring safety and maintaining high standards in the aviation industry. This legislative instrument, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addressing issues such as engine nacelle fire extinguisher wiring in the Saab SF340 Series aeroplanes. The directive, AD/SF340/51, was introduced to address a problem identified in the wiring connections of the engine nacelle fire extinguishers on specified models of Saab aeroplanes, ensuring that these connections are correctly installed to prevent potential fire hazards. The Civil Aviation Safety Authority, as the enacting body, aims to maintain the highest safety standards in aviation, thereby protecting public safety and promoting efficient and safe air navigation in Australia.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the safety directives for certain aircraft within the Australian aviation industry. This particular legislative instrument pertains to the SAAB SF340 Series aeroplanes, specifically those serial numbers SF340-004 through -159 for Model SF 340A and serial numbers 340B-160 through -345 for Model 340B. The directive mandates an inspection and modification of the engine nacelle fire extinguisher wiring in accordance with SAAB Aircraft AB Service Bulletin SAAB 340-26-015 dated 23 November 1995, which supersedes AD/SF340/39. This action is taken to ensure compliance with safety standards by minimising the risk of incorrect installation of fire extinguisher electrical wiring connections. Compliance with these safety directives is required no later than the next 4000 flight hour inspection (C check) following 29 February 1996.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, address the issue of engine nacelle fire extinguisher wiring for certain Saab SF340 Series aeroplanes. The directive AD/SF340/51 pertains to the inspection and modification of the wiring for Saab SF340A aeroplanes with serial numbers ranging from SF340-004 to SF340-159, and Saab SF340B aeroplanes with serial numbers from 340B-160 to 340B-345 (section 3). This directive mandates that the wiring be inspected and modified in line with Saab Aircraft AB Service Bulletin SAAB 340-26-015 dated 23 November 1995. It also references Swedish (LFV) SAD 1-079, indicating cross-jurisdictional relevance and compliance with safety standards (section 3). Compliance with this directive is required no later than the next 4000 flight hour inspection, commonly known as a C check, following 29 February 1996 (section 3).
Operators of the specified Saab SF340 Series aeroplanes are obligated to ensure that the required inspection and modification of the engine nacelle fire extinguisher wiring is carried out as stipulated. This includes adherence to the guidelines set forth in the Saab Aircraft AB Service Bulletin SAAB 340-26-015, which was issued to address the risk of incorrect wiring connections. Failure to comply with these requirements can result in the aeroplane not being airworthy, potentially leading to safety hazards (section 3). Additionally, operators must keep records of the inspections and modifications performed, as well as any subsequent inspections to verify compliance (section 3).
Failure to comply with the directives outlined in AD/SF340/51 can result in significant consequences. The primary concern is the potential for airworthiness issues, which can lead to the grounding of the affected aeroplanes. Additionally, operators may face regulatory scrutiny, enforcement actions, and financial penalties. Although the specific penalties are not detailed in the Civil Aviation Regulations 1998, non-compliance with airworthiness directives generally can lead to enforcement actions under the Civil Aviation Act 1988, which includes fines and other penalties as determined by the court. The overarching aim of these measures is to ensure that all safety directives are met to maintain the highest standards of aviation safety (section 3).
