Overview

The Civil Aviation Safety Regulations 1998, enacted by the Australian Government, aim to ensure the safety and efficiency of civil aviation within Australia. Specifically, Part 39 - 105 of the regulations includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which are critical for maintaining the safety standards of aircraft and aeronautical products. The regulations were introduced to address the need for consistent and stringent safety measures across the aviation industry, ensuring that all aircraft and aeronautical products comply with national and international safety standards. This legislative instrument was developed by the Parliament of Australia and aims to mitigate risks associated with aviation safety by setting clear directives and requirements for aircraft maintenance and operations. The Airworthiness Directive issued under this regulation focuses on the inspection and maintenance of the engine to firewall attachment on General Avia F22 Series Aeroplanes to prevent potential structural failures.

Scope and Application

The Civil Aviation Safety Regulations 1998 (CASR 1998) govern airworthiness directives (ADs) within Australia, ensuring that aircraft and aeronautical products meet safety standards. Specifically, AD/F22/1 applies to the General Avia F22 Series Aeroplanes, including models F22A, F22B, F22C, and F22R. The directive mandates a visual inspection of the structure surrounding the four bolts on the engine mount attachment at the firewall. This inspection must be performed before further flight after the directive's effective date of 15 November 2004. If any cracks or failures are detected, the operator must report the damage and the aircraft's total hours in service to ENAC, the Italian Airworthiness Authority, for further determination of required actions. This directive extends to ensuring the safe operation of these aircraft within Australia, and its implementation is overseen by the Civil Aviation Safety Authority (CASA), as delegated by David Villiers on 12 November 2004.

Key Provisions

The Civil Aviation Safety Regulations 1998, specifically in Part 39, include a detailed Airworthiness Directive (AD) issued under subregulation 39.1(1). This AD applies to General Avia F22 Series Aeroplanes, including models F22A, F22B, F22C, and F22R. The directive, titled AD/F22/1 "Engine to Firewall Attachment," mandates a visual inspection of the structure surrounding the four bolts on the engine mount attachment at the firewall. The inspection must be carried out before further flight, after 15 November 2004, as stated in the compliance section. The AD requires that the inspection be performed by accessing the area from the cabin below the instrument panel. If direct access is not possible, the upper panels of the firewall bulkhead should be removed, with the right side being removed entirely and the left side partially, to facilitate inspection from the engine bay. The primary objective of this directive is to detect any cracking or failure in the specified area, which could potentially lead to the detachment of the engine mounts from the firewall structure. In the event that cracks or failures are identified, the directive requires that the details of the damage and the aircraft's total hours in service be reported to ENAC (the Italian Airworthiness Authority) before further flight. The contact person at ENAC is Mr. C. Eminente, and the email address for reporting is c.eminente@enac.rupa.it. This directive references ENAC AD 2004-376. Entities and parties governed by this AD must adhere to the outlined inspection and reporting requirements. Specifically, they must conduct a thorough visual inspection of the engine mount attachment at the firewall, as specified, and report any detected issues to ENAC. Failure to comply with these obligations could result in significant safety risks, as the potential detachment of engine mounts could lead to catastrophic in-flight failures. Consequently, the AD imposes strict requirements on aircraft operators and maintenance personnel to ensure compliance with the safety standards set forth. Failure to comply with the provisions of this Airworthiness Directive can result in serious consequences. The AD does not explicitly state penalties for non-compliance; however, the overarching Civil Aviation Safety Regulations 1998 provide for potential enforcement actions, including fines and other civil or criminal penalties. The exact penalties would be determined based on the specific circumstances of non-compliance and the potential risks posed to aviation safety. It is imperative that all parties involved strictly adhere to the AD to avoid any legal repercussions and to maintain the highest standards of aircraft safety.
