AD/CERES/4 Amdt 1 - Mixture Control Lever Quadrant - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as the foundational legal framework for ensuring the safety and efficiency of civil aviation within Australia. Among the numerous provisions outlined in these regulations, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives addresses specific safety mandates for various aircraft types. The legislation aims to bridge the gap in ensuring that all aircraft meet stringent safety standards, ultimately protecting passengers and crew. This particular amendment, AD/CERES/4, focuses on the modification of mixture control lever quadrants in Ceres Series Aeroplanes, with the objective of clearly marking the minimum lean and cut-off positions to enhance safety during flight operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the scope and application of airworthiness directives issued by the Civil Aviation Safety Authority (CASA) concerning aircraft safety. This legislation applies to all persons, entities, and industries involved in the operation of aircraft, particularly focusing on the modification and maintenance of aircraft systems. The geographic reach of this regulation is national, as it applies throughout the Commonwealth of Australia, ensuring a uniform standard of safety across all aviation activities. The regulations mandate compliance with specific airworthiness directives, such as AD/CERES/4Amdt 1, which addresses modifications to the mixture control lever quadrant on Ceres Series Aeroplanes. This directive specifies that all models of the Ceres Series Aeroplanes must have the mixture control lever quadrant marked to indicate the minimum lean position and the rearmost position. The application is immediate, requiring compliance forthwith upon the directive's effective date of 9 September 1999. Any modifications carried out in accordance with the directive are deemed to meet the requirements of the regulation. The legislation does not explicitly state any exclusions, exemptions, or thresholds but relies on subordinate instruments to further define and extend its application.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, outlines the requirements for airworthiness directives concerning the CA-28 (Ceres) series aeroplanes. The directive AD/CERES/4 Amendment 1 pertains to the modification of the mixture control lever quadrant (AD/CERES/4Amdt 1). The key requirement of this directive is that all models of the Ceres series aeroplanes must have their mixture control lever quadrants marked or remarked to clearly indicate specific positions: the minimum lean position, to be designated "LEAN," and the rearmost position, to be designated "CUT OFF." This modification is intended to ensure that pilots can easily identify these critical positions, which is essential for safe operation of the aircraft. Compliance with this airworthiness directive is mandatory and must be carried out forthwith. The directive specifies that any modifications performed in accordance with AD/CA-28/4 will satisfy the requirements of AD/CERES/4Amdt 1. This ensures that the modifications are standardised and meet the necessary safety criteria. The directive became effective on 9 September 1999, and it is the responsibility of the aircraft operators or owners to ensure that the modifications are completed before this date to remain compliant with the regulations. Failure to comply with the airworthiness directive could have significant legal and safety implications. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and non-compliance may result in enforcement actions. While the specific penalties are not detailed in the directive, non-compliance with airworthiness directives can lead to serious consequences, including fines, suspension of the aircraft's operating certificate, and potential criminal charges in cases of gross negligence or endangerment of public safety. Therefore, it is crucial for operators and owners of Ceres series aeroplanes to adhere strictly to the requirements outlined in AD/CERES/4Amdt 1 to avoid any legal repercussions and ensure the continued airworthiness of their aircraft.
