Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B09694, specifically address the maintenance and airworthiness of Fokker F27 Series aeroplanes. Enacted to ensure the safety of civil aviation and to close a gap identified in the maintenance requirements for certain Fokker F27 aircraft, this legislation was introduced by the Australian Government to align with international standards and directives. The legislation aims to ensure that Australian registered Fokker F27 aircraft meet specific technical requirements, particularly those concerning the fuselage bracket attachment fasteners, as outlined by the Requirement Document. The policy objective is to enhance the safety and reliability of these aircraft by mandating adherence to specified technical standards and compliance deadlines.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to Fokker F27 Series aeroplanes with specific serial numbers. The regulation mandates compliance with Technical Requirements of RLD AD 91-112, necessitating actions to address reports of loose bolts and hi-shear pins in the brackets on the front and rear spars. This directive pertains to Australian registered aircraft, with the effective date of compliance set as 12 December 1991, slightly extended from the original RLD requirement. The directive is a direct application of the Civil Aviation Safety Authority’s mandate to ensure the airworthiness of aircraft within Australia, thereby affecting aircraft operators and maintenance personnel who must adhere to these standards. The scope of this directive is limited to the specified Fokker F27 Series aeroplanes, and it does not explicitly state exclusions or exemptions, though compliance is expected for the mentioned serial numbers.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety directives for certain aircraft models, including the Fokker F27 Series Aeroplanes. The regulation in focus is AD/F27/127, which pertains to the fuselage bracket attachment fasteners of specific serial numbers (10102 thru 10433, 10435 thru 10443, and 10446 thru 10450). This directive mandates actions that align with the technical requirements set forth in RLD AD 91-112, with reference to Fokker Service Bulletin F27/57-23 Revision 6. The aim is to ensure that the aircraft's structural integrity is maintained, particularly addressing reports of loose bolts and hi-shear pins in the brackets on the front and rear spars. Compliance with this directive is essential for Australian-registered aircraft, with an effective date set at 12 December 1991.
For the entities and parties governed by this regulation, compliance is not merely a procedural formality but a critical safety measure. Operators of the specified Fokker F27 models must adhere to the technical requirements outlined in RLD AD 91-112. This entails conducting thorough inspections and necessary repairs or replacements of the fuselage bracket attachment fasteners. The directive is clear that the compliance must align with the specifications provided in the requirement document, which has been revised for Australian-registered aircraft. Failure to meet these compliance standards could result in severe safety implications, including the potential for in-flight structural failures.
Breaching the provisions of this safety directive carries significant consequences. The Civil Aviation Regulations 1998 outline that any non-compliance with AD/F27/127 can lead to enforcement actions. The severity of penalties may include substantial fines and, in extreme cases, the grounding of the affected aircraft. The exact penalties are determined by the Civil Aviation Safety Authority (CASA) and can vary based on the nature and extent of the non-compliance. Operators must ensure that all corrective actions are completed within the stipulated timeframe to avoid these repercussions, as regulatory enforcement is stringent to maintain high safety standards in civil aviation.
In summary, the Civil Aviation Regulations 1998, under Part 39 - 105, mandate specific safety measures for the Fokker F27 Series Aeroplanes through AD/F27/127. This includes ensuring the fuselage bracket attachment fasteners meet the technical requirements of RLD AD 91-112. Compliance is non-negotiable, with stringent obligations for operators to perform the necessary inspections and repairs. Failure to adhere to these regulations can result in severe penalties, including fines and aircraft grounding, highlighting the critical importance of following these directives to ensure aviation safety.
