Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, introduce the Civil Aviation Safety Authority Schedule of Airworthiness Directives (ADs) to ensure the safety and reliability of aircraft operations in Australia. This legislation was enacted to address issues related to the airworthiness of aircraft and to establish clear guidelines for maintaining these standards. The ADs are created and enforced by the Civil Aviation Safety Authority (CASA) under the authority delegated by the Parliament of Australia. The policy objective of these regulations is to mandate specific maintenance actions to rectify known safety issues, as exemplified by AD/F27/114 Amendment 1 concerning the Fokker F27 Series Aeroplanes. This particular amendment pertains to the main landing gear torque links, requiring compliance with the updated service bulletin from Dowty Rotol to rectify manufacturing defects identified in certain batches of torque links. The Fokker F27 Series Aeroplanes Airworthiness Directive AD/F27/114 Amendment 1 highlights CASA's proactive approach in addressing manufacturing defects that could potentially compromise aircraft safety. The directive mandates corrective action for specific models of Fokker F27 aeroplanes, ensuring that the main landing gear torque links are inspected and serviced in accordance with the latest service bulletin from the manufacturer. This amendment extends the scope of previously identified affected batches, thereby enhancing the overall safety and reliability of these aircraft in Australian airspace. The directive reflects the commitment of the Commonwealth of Australia, through CASA, to maintain stringent safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies specifically to Fokker F27 series aeroplanes. This legislation mandates that all models of the Fokker F27 aeroplane must comply with Airworthiness Directive AD/F27/114 Amendment 1, which pertains to the main landing gear torque links. The directive requires compliance in accordance with the Dowty Rotol Service Bulletin 32-161B Revision 2. This regulation necessitates corrective actions for identified issues with the torque links that were incorrectly machined during the manufacturing process. The directive’s scope is clearly defined, extending to all Fokker F27 series aeroplanes, and its application is stringent, demanding adherence before 1 January 1989. This mandate ensures the safety and airworthiness of the aircraft by addressing specific structural concerns identified by the manufacturer.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives for Fokker F27 Series Aeroplanes, includes AD/F27/114 Amendment 1. This directive applies to all models of Fokker F27 aeroplanes and pertains to the main landing gear torque links (section 11/87). The requirement is that all Fokker F27 aeroplanes must comply with Dowty Rotol Service Bulletin 32-161B Revision 2. The compliance must be achieved prior to 1 January 1989. The directive responds to a manufacturer's report that several torque links were incorrectly machined during the production process. Amendment 1 extends the batch numbers identified as having been incorrectly machined to ensure that all affected units are addressed. Entities governed by this legislation, including aircraft operators, maintenance service providers, and the manufacturers themselves, have specific obligations to adhere to the directive. Operators must ensure that their Fokker F27 aeroplanes are inspected and, if necessary, have their main landing gear torque links corrected to meet the specifications outlined in Dowty Rotol SB 32-161B R2 before the specified compliance date. Maintenance service providers are required to perform the necessary inspections and modifications as per the directive to ensure airworthiness. Manufacturers must ensure that all newly produced or repaired torque links conform to the correct specifications to avoid recurrence of the issue. Failure to comply with the directive can lead to severe consequences. Non-compliance with airworthiness directives is a serious offence under Australian aviation law. The penalties for non-compliance can include substantial fines and potential criminal charges against responsible individuals. The severity of penalties can vary, but under the Civil Aviation Act 1988, the maximum penalties for non-compliance with airworthiness directives can include fines up to $210,000 for individuals and up to $1,050,000 for corporations, in addition to potential imprisonment terms for responsible officers. Furthermore, non-compliance can also lead to the grounding of the aircraft, which can have significant operational and financial repercussions for operators.
