AD/AC/24 - Fuel Pressure Gauge Vent Drain - Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, play a crucial role in regulating civil aviation safety and operations. One of the amendments to these regulations is the Airworthiness Directive (AD) pertaining to Twin Commander (Gulfstream/Rockwell/ Aerocommander 500, 600, and 700) series aeroplanes, specifically focusing on the installation of the fuel pressure gauge vent drain. This AD was introduced to address safety issues related to the fuel system in these aircraft models. The objective of this directive, as mandated by the Civil Aviation Safety Authority, is to ensure that all applicable aircraft are equipped with a correctly installed fuel pressure gauge vent drain to mitigate potential safety risks. This amendment requires immediate compliance from the operators of the specified models, barring certain serial numbers, to maintain the highest standards of aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives concerning Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes. This legislation applies to all models within the specified serial numbers, excluding those with serial numbers 1133, 1153, 1156, and 1162, as well as model 720 and pressurised versions of 680F. The directive mandates the installation of a fuel pressure gauge vent drain, as outlined in either Aero Commander Service Bulletin No. 78 or FAA AD 62-8-1, and compliance must be achieved forthwith. The geographic reach of this Act is national, as it applies across Australia and is enforced under Commonwealth regulations. There are no stated exclusions or exemptions within this directive, and the Act extends its application through the subordinate instruments provided by Aero Commander and the FAA.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, outline specific safety directives for certain aircraft models. Section 105.010 addresses the installation of a fuel pressure gauge vent drain for Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes, as specified in AD/AC/24. This directive is critical for ensuring the safe operation of these aircraft by preventing fuel contamination in the gauge system, which could lead to operational failures or hazards. Compliance with these directives is mandatory for all Twin Commander aircraft models, except for those with serial numbers 1133, 1153, 1156, and 1162, and certain models such as the 720 and pressurised versions of the 680F. The requirement for compliance is immediate, as stipulated in section 105.015, meaning that the installation must be completed forthwith. The compliance can be achieved by adhering to the specifications detailed in either Aero Commander Service Bulletin No. 78 or FAA AD 62-8-1. Entities and parties governed by these regulations must ensure that the installation of the fuel pressure gauge vent drain is carried out according to the prescribed standards. This involves verifying the specifications and ensuring that the installation meets the criteria outlined in the referenced documents. It is the responsibility of aircraft owners, operators, and maintenance personnel to ensure that the installations are completed correctly and documented as per the regulatory requirements. Failure to comply with these safety directives may result in significant legal and operational consequences. Section 105.020 specifies that non-compliance with these directives is an offence. The penalties for breaching these regulations can be substantial, with potential fines and other civil or criminal consequences. Although the exact maximum penalties are not detailed in the provided text, it is clear that adherence to these directives is not optional and carries the risk of enforcement action from the Civil Aviation Safety Authority.
