Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation in Australia. Part 39 of these regulations outlines the requirements for airworthiness directives, which are legally enforceable rules issued by CASA to correct an unsafe condition of an aircraft. The specific directive AD/SF340/19, issued in 1991, addresses the ice protection requirements for the SAAB SF340 series aeroplanes. This directive was introduced in response to the revision C of LFV AD 1-004, which mandated specific technical actions to ensure the aircraft's safety during icing conditions. The policy objective is to maintain a high standard of airworthiness and operational safety by ensuring that all specified aircraft comply with the necessary technical requirements before a specified compliance date.
The directive mandates that certain models of the SAAB SF340A series aeroplanes, specifically those with serial numbers ranging from 340A-004 to 340A-048, must adhere to the technical requirements outlined in revision C of LFV AD 1-004. For serial numbers 340A-004 to 340A-028, additional actions are required as specified in Parts (B) and (C) of the same directive. This compliance must be achieved before 30 April 1991, unless the actions have already been completed. The directive references specific service bulletins (SBs) issued by SAAB to guide the necessary actions.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, pertains specifically to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives concerning the SAAB SF340 Series Aeroplanes, with a focus on ice protection measures. This legislation applies to the SAAB SF340A series aeroplanes with serial numbers ranging from 340A-004 through 340A-048. The directive mandates actions in accordance with the technical requirements outlined in the Swedish LFV AD 1-004 revision C Part (A) for all specified serial numbers. Additionally, for serial numbers 340A-004 through 340A-028, the directive requires compliance with Parts (B) and (C) of the same revision. This requirement ensures that these aircraft maintain specified safety standards, particularly in terms of ice protection, to prevent operational risks associated with ice accumulation on the aeroplanes. Compliance with these directives must be achieved before 30 April 1991, unless the necessary actions have already been completed. The directive also references specific Service Bulletins (SBs) SF340-30-008, SF340-54-002, and SF340-76-006, which provide further technical guidance for implementing the required changes.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes the directive AD/SF340/19 concerning the SAAB SF340 series aeroplanes and their ice protection measures (section 1). The directive applies to the SF340A series with serial numbers (S/No) ranging from 340A-004 to 340A-048 (section 2). It requires that all aircraft within this series comply with the technical requirements set out in LFV (Swedish) AD 1-004 revision C Part (A) (section 3). Additionally, aircraft with serial numbers 340A-004 to 340A-028 must also adhere to the technical requirements of LFV AD 1-004 revision C Part (B) and (C) (section 4). Reference is made to SAAB Service Bulletins SF340-30-008, SF340-54-002, and SF340-76-006 for further guidance (section 5).
The obligations under this directive require that compliance must be achieved unless the specified actions have already been performed. The compliance deadline is set for before 30 April 1991 (section 6). This directive responds to Revision C of LFV AD 1-004 and is linked to Revision 3 of Service Bulletin SF340-30-008, which adjusts the service check interval as detailed in the Maintenance Review Board Report TASK 30-20-00(5) (section 7). Operators of the affected aircraft must ensure that these technical requirements are met to maintain the airworthiness of their aircraft.
Failure to comply with the provisions of this directive may result in civil or criminal consequences. The exact nature of these consequences would depend on the extent of non-compliance and the specific regulatory framework under which CASA operates. However, penalties for non-compliance with CASA directives can be severe and may include fines or other sanctions that could affect the operational status of the aircraft or the certification of the operator (section 8). The maximum penalties are not explicitly stated in the directive, but they can be significant given the critical nature of the safety measures outlined.
In summary, AD/SF340/19 mandates specific technical actions for the SAAB SF340 series aeroplanes to ensure ice protection measures are effective, with stringent compliance requirements that must be met by a specific deadline. Non-compliance with these provisions may lead to significant civil or criminal penalties, reflecting the importance of adhering to airworthiness directives to ensure aviation safety.
