Overview

The Civil Aviation Safety Regulations 1998 (CASR 1998), enacted by the Australian Parliament, aim to ensure the safety of civil aviation operations within Australia. One such regulatory measure is the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) to address safety concerns identified in specific aircraft models. AD/CA25/12, issued on 20 November 2003 and becoming effective on 26 November 2003, targets the Skyfox Aviation (Hedaro) CA25 Series aeroplanes to mitigate the risk of rudder pedal cable detachment, which has been reported by operators. The directive mandates a close visual inspection of the rudder cable attachment lugs and requires the removal or repair of any defective pedal assemblies to prevent unsafe conditions. This action is intended to enhance the safety and reliability of the specified aircraft models, ensuring compliance with aviation safety standards.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, encompass Airworthiness Directives that are applicable to the aviation industry, with particular attention to the Skyfox Aviation (Hedaro) CA 25 Series aeroplanes. This Airworthiness Directive (AD) applies to the identified series of aeroplanes, necessitating a close visual inspection of the rudder cable to rudder pedal attachment lugs, focusing on the lugs welded to the rudder pedals, particularly the firewall side. Any pedal assemblies found defective during this inspection must be removed from service or repaired before further flight, adhering to an approved repair scheme. The AD applies to the aforementioned aeroplanes and requires compliance within ten flying hours from the directive’s effective date and at each subsequent 100-hour scheduled inspection. This regulatory instrument extends its reach across the Commonwealth, ensuring adherence to national aviation safety standards.

Key Provisions

The Civil Aviation Safety Regulations 1998, particularly Part 39 - 105, contain an Airworthiness Directive (AD) issued by a delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1(1). This AD, AD/CA25/12, specifically addresses the issue of the rudder pedal cable attachment lugs on Skyfox Aviation (Hedaro) CA 25 Series aeroplanes. The directive mandates a close visual inspection of the rudder cable to rudder pedal attachment lugs on both the left and right rudder pedals, with a focus on the weld area where the lug attaches to the pedal, especially on the firewall side (AD/CA25/12). Any pedal assemblies found to be defective during this inspection must be removed from service or repaired before further flight. Repairs must adhere to an approved repair scheme (AD/CA25/12). This AD imposes obligations on the operators of the Skyfox Aviation (Hedaro) CA 25 Series aeroplanes to conduct a thorough visual inspection of the specified parts within ten flying hours from the effective date of the directive and at every 100-hour scheduled inspection thereafter. Operators are required to pay particular attention to the weld area where the rudder cable lug attaches to the rudder pedal, ensuring that any defects identified are either rectified or the assembly is removed from service. Furthermore, the directive specifies that any repairs to the rudder pedal assemblies must comply with an approved repair scheme (AD/CA25/12). The AD does not explicitly outline offences, penalties, or specific civil/criminal consequences for non-compliance. However, given the nature of airworthiness directives under the Civil Aviation Safety Regulations 1998, failure to comply with this AD could potentially result in serious safety risks and subsequent enforcement actions by CASA. The potential consequences of non-compliance might include grounding of the aircraft, which could lead to significant operational disruptions and financial losses for the operators. Additionally, CASA may impose administrative penalties or other regulatory actions to ensure compliance with the safety directive.
