COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 320 Series Aeroplanes
AD/CESSNA 320/31 Auxiliary Fuel Pump Wiring Modification 12/89
Applicability: All models 320 which have been modified in accordance with Cessna Service Bulletin MEB 88-3.
Requirement: Unless already accomplished, action in accordance with Cessna Service Bulletin MEB 88-3 Revision 1.
Note: This Requirement does not apply to aeroplanes that have not incorporated SB MEB 88-3.
Compliance: Prior to the issue of the next Maintenance Release after 31 December 1989.
Background: Compliance with the original issue of SB MEB88-3 was not considered to warrant the issue of an Airworthiness Directive. This AD is raised to ensure that necessary features of Revision 1 are incorporated into modified aeroplanes.
Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, aim to ensure the safety and efficiency of civil aviation operations within Australia. These regulations are comprehensive and address various aspects of aviation safety, including the issuance of airworthiness directives to maintain the safety standards of aircraft. One such directive, AD/CESSNA 320/31, pertains specifically to the Cessna 320 Series Aeroplanes and was introduced to address a safety concern related to the auxiliary fuel pump wiring. This directive was issued to ensure that all modified models of the Cessna 320, which had been subject to a specific service bulletin (MEB 88-3), incorporated essential modifications detailed in the revised service bulletin (Revision 1). The policy objective behind this directive was to mandate compliance with these modifications to prevent potential safety hazards associated with the auxiliary fuel pump wiring.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all models of Cessna 320 aeroplanes that have undergone modifications in line with the Cessna Service Bulletin MEB 88-3. This regulation is applicable to aeroplanes modified as per the specified service bulletin and mandates compliance with Cessna Service Bulletin MEB 88-3 Revision 1. The directive ensures that all modified aeroplanes incorporate the necessary features outlined in Revision 1, with compliance required prior to the issuance of the next Maintenance Release following 31 December 1989. It is important to note that this directive does not apply to aeroplanes that have not incorporated Service Bulletin MEB 88-3. The scope and enforcement of these regulations are further detailed in subordinate instruments, which may include additional clarifications and specific requirements to ensure compliance and safety in civil aviation.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD). For Cessna 320 Series aeroplanes, AD/CESSNA 320/31 mandates an auxiliary fuel pump wiring modification (Section 12/89). This directive applies to all models 320 that have been modified in accordance with Cessna Service Bulletin MEB 88-3. The requirement is to implement the modifications outlined in Cessna Service Bulletin MEB 88-3 Revision 1, unless these modifications have already been completed. Notably, this directive does not apply to aeroplanes that have not incorporated the original Service Bulletin MEB 88-3.
Compliance with AD/CESSNA 320/31 must be achieved before the issue of the next Maintenance Release following 31 December 1989. This timeline is crucial for ensuring that the necessary modifications are incorporated into the aircraft to maintain airworthiness standards. The AD was introduced because compliance with the original Service Bulletin MEB 88-3 was not deemed significant enough to warrant an Airworthiness Directive initially. However, the update in Revision 1 necessitated this directive to ensure that modified aeroplanes incorporate these critical updates.
Entities governed by this Act, such as aircraft operators and maintenance providers, are obligated to ensure that the specified modifications are carried out on applicable Cessna 320 aeroplanes. This includes reviewing the aircraft's modification history to determine whether the Service Bulletin MEB 88-3 Revision 1 has already been implemented. If not, the modifications must be completed by the specified deadline to avoid any compliance issues. These obligations are integral to maintaining the safety and airworthiness of the aircraft, ensuring they meet the standards set by CASA.
Failure to comply with AD/CESSNA 320/31 may result in serious consequences. CASA has the authority to enforce penalties for non-compliance, which could include fines or other civil penalties as stipulated in the Civil Aviation Act 1988. Additionally, operating an aircraft that does not comply with these directives may lead to the aircraft being deemed unairworthy, resulting in grounding until the required modifications are completed. These measures are in place to uphold the highest standards of aviation safety and to prevent any potential hazards arising from non-compliance with airworthiness directives.
