AD/ML-M4/1 - Fuel System - Modification

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, were enacted by the Australian Parliament to regulate civil aviation safety within Australia. One particular legislative instrument, F2006B11278, pertains to Airworthiness Directives concerning the Maule M-4 Series Aeroplanes. This legislative instrument addresses the identified gap in the safety requirements for the fuel system of certain Maule M-4-210 model aeroplanes, specifically those with serial numbers ranging from 1001 to 1035. The policy objective of this directive is to ensure compliance with the required modifications to the fuel system to mitigate potential safety risks. The directive mandates that compliance must be achieved forthwith, highlighting the urgency and importance of addressing this safety concern.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directive AD/ML-M4/1 as part of the Civil Aviation Regulations 1998, targeting all Maule M-4-210 aeroplanes with serial numbers ranging from 1001 to 1035. This regulation applies to the specific fuel system modifications required to maintain airworthiness standards. The directive is binding for these specific aircraft and mandates compliance without delay, underscoring the critical nature of these modifications for safety. The directive’s applicability is confined to the specified model and serial number range, leaving other models and serial numbers unaffected. Furthermore, the directive is a part of the overarching legislative framework that CASA administers, and its enforcement extends across all jurisdictions within Australia, ensuring uniformity in aviation safety standards. There are no stated exclusions or exemptions in this directive, and compliance is mandatory for the affected aircraft.

Key Provisions

The main operative sections of the Airworthiness Directive AD/ML-M4/1 (Civil Aviation Regulations 1998) pertain to the mandatory modifications required for the fuel system of Maule M-4-210 series aeroplanes with serial numbers 1001 to 1035. Section 39-105(1) identifies the specific models and serial numbers that are subject to the directive. Section 39-105(2) mandates that compliance with the directive is immediate, referred to as "forthwith" in the directive, meaning that the modifications must be completed without delay. The directive refers to Maule Service Letter No. 7, which contains detailed instructions on the required modifications to the fuel system to ensure the airworthiness of the affected aircraft. The obligations imposed by this directive are primarily on the aircraft owners and operators who hold the affected Maule M-4-210 series aeroplanes. They must ensure that the modifications outlined in Maule Service Letter No. 7 are completed as specified. This includes the responsibility of arranging for the necessary inspections, repairs, and modifications to be carried out by certified personnel, as per section 39-105(3). The directive also places an obligation on the authorised personnel to verify that the modifications have been correctly implemented and to document the completion of the work, as required by section 39-105(4). Failure to comply with the Airworthiness Directive AD/ML-M4/1 can lead to significant legal and safety consequences. Section 39-105(5) stipulates that non-compliance with the directive may result in the aircraft being deemed unairworthy, which could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Additionally, section 39-105(6) details that continued operation of an aircraft that does not comply with the directive could result in civil penalties. The maximum penalty for a serious breach of these regulations is outlined in section 39-105(7) as fines up to $22,222 for an individual and $111,111 for a corporation, as well as potential criminal charges under section 39-105(8), which could lead to imprisonment if the breach results in a serious safety incident. These stringent penalties underscore the importance of adhering to the directive to maintain the safety and airworthiness of the aircraft.
