Overview
The Civil Aviation Regulations 1998, as amended, are fundamental to maintaining airworthiness standards within Australia, overseen by the Civil Aviation Safety Authority (CASA). This particular legislative instrument, F2006B06977, pertains to the Saab SF340 series aeroplanes and specifically addresses a safety directive concerning the rudder nose rib of certain models. The enactment aims to rectify a reported issue of cracked nose ribs on the front spar of the rudder, which could potentially lead to jamming between the fin and rudder, causing safety hazards. This directive mandates adherence to SAAB Service Bulletin 340-55-032 to ensure compliance and mitigate the identified risks.
The policy objective behind this directive is to enhance the safety of civil aviation by ensuring that all aircraft within the specified models and serial numbers undergo necessary maintenance to prevent structural failures. CASA issues these airworthiness directives to maintain a high standard of safety and reliability in Australian airspace, thus protecting both passengers and crew on board these aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, governs the safety directives applicable to various aircraft, with the focus here being on the Saab SF340 Series aeroplanes. The scope of this particular directive, AD/SF340/48, pertains to the rudder nose rib and mandates action in accordance with SAAB Service Bulletin 340-55-032. It applies to the SF 340A models with serial numbers ranging from 004 to 159 and the SF 340B models with serial numbers from 160 to 369. The legislation requires compliance with the specified requirements, as outlined in the Requirement Document, effective from 7 December 1995. The directive responds to a reported issue of a cracked nose rib on the front spar of the rudder, which, if left unaddressed, could lead to jamming between the fin and rudder due to deformation of the cracked nose rib web. The regulation underscores the importance of adhering to specific safety measures to prevent potential operational hazards.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, outline the requirements for the Saab SF340 Series aeroplanes concerning the rudder nose rib. The directive AD/SF340/48 issued on 13/95 mandates that the action be taken in accordance with the SAAB Service Bulletin 340-55-032. This directive applies to the model SF 340A with serial numbers ranging from 004 to 159, and model 340B with serial numbers from 160 to 369. The directive references LFV AD 1-074 and requires compliance as specified in the Requirement Document, with a revised effective date of 7 December 1995. The background to this directive involves a report of a cracked nose rib on the front spar of the rudder, which could lead to jamming between the fin and rudder due to deformation of the cracked nose rib web.
The obligations imposed by this Act on the relevant parties include ensuring that the specified actions are carried out as per the SAAB Service Bulletin 340-55-032. This involves inspecting the rudder nose rib of the affected models and implementing any necessary repairs or modifications to prevent potential jamming. Operators must ensure that the aircraft are compliant with the directives outlined in the Requirement Document by the specified effective date. Documentation of compliance and any actions taken must be maintained for regulatory review.
Failure to comply with the provisions of this directive can lead to various consequences. Under the Civil Aviation Regulations, non-compliance could result in safety hazards that might lead to aircraft being grounded until the issues are resolved. The Act does not explicitly state penalties, but non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA), which may include fines or other administrative measures. Additionally, operators may face civil liabilities for any incidents or accidents resulting from non-compliance.
