AD/FU24/45 - Fuel Quantity Indication - Modification

Overview

The Civil Aviation Regulations 1998, as amended, are an extensive set of rules designed to ensure the safety and efficiency of civil aviation in Australia. Part 39 of these regulations pertains specifically to airworthiness directives, which are legally enforceable rules issued by the Civil Aviation Safety Authority (CASA) to correct an unsafe condition of an aircraft, product, part, appliance, or person. Enacted by the Australian Parliament, this regulatory framework was introduced to address the need for stringent safety measures in civil aviation. The overarching policy objective of these regulations is to maintain the highest possible safety standards in the operation of aircraft within Australian airspace. One specific example of such a directive is AD/FU24/45, which pertains to the modification of fuel quantity indication systems in Airparts (NZ) Ltd. FU 24 Series Aeroplanes. This directive applies to all models equipped with mechanical fuel quantity indicators at the inboard end of the left-hand fuel tank system. The requirement is to either fit electrical indicators or reposition the left-hand indicator assembly according to a scheme approved by the Secretary. Compliance with this directive is mandatory before 30 September 1973, ensuring that these aircraft meet the necessary safety standards to prevent potential fuel-related issues that could compromise flight safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Airworthiness Directives issued by the Civil Aviation Safety Authority. One such directive, AD/FU24/45, applies to all models of FU 24 Series Aeroplanes manufactured by Airparts (NZ) Ltd. that are equipped with mechanical type fuel quantity indicators fitted to the inboard end of the left-hand fuel tank system. The directive mandates modifications to the fuel quantity indicating system, requiring either the fitting of electrical indicators or the repositioning of the left-hand indicator assembly to a scheme approved by the Secretary. Compliance with these modifications must be achieved prior to 30 September 1973. This regulation is part of a broader framework that ensures the safety and airworthiness of civil aircraft within Australia and is enforced by the Civil Aviation Safety Authority. The directive extends its applicability across the entire Commonwealth of Australia, encompassing all entities and industries involved in the maintenance and operation of the specified aircraft models.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, mandate modifications to the fuel quantity indication system for all models of FU 24 Series Aeroplanes manufactured by Airparts (NZ) Ltd. (AD/FU24/45). The key requirement (Section 1) is to modify the fuel quantity indicating system by either fitting electrical indicators or repositioning the left hand indicator assembly to a scheme approved by the Secretary. It is noted that Airparts (NZ) Ltd. drawing 246158 is an acceptable means of compliance for these modifications. The Act imposes specific obligations on the parties involved, including Airparts (NZ) Ltd. and any owners or operators of FU 24 Series Aeroplanes. These parties are required to ensure that the modifications outlined in the Airworthiness Directives are implemented before the compliance deadline of 30 September 1973. This deadline is non-negotiable and must be strictly adhered to in order to maintain the airworthiness of the aircraft. Failure to comply with the requirements set forth in the Airworthiness Directives can lead to serious consequences. The Civil Aviation Regulations 1998 stipulate that non-compliance with these directives may result in penalties. While the specific penalties are not detailed in this particular directive, it is understood that non-compliance with CASA directives can lead to significant financial penalties, operational restrictions, or even the grounding of the affected aircraft. Additionally, the repercussions can extend to criminal charges and imprisonment in cases of gross negligence or willful disregard of safety regulations. It is imperative for all parties involved to take these obligations seriously to avoid any legal or operational repercussions.
