AD/AUS/4 - Aileron Control Push Rod

Overview

The Civil Aviation Regulations 1998, as amended by the Civil Aviation (Airworthiness) Regulations 1998, were enacted to ensure the airworthiness of aircraft operating within Australian airspace. This legislation was introduced to address the need for comprehensive regulations governing the maintenance and operation of aircraft to ensure public safety and to harmonise Australian standards with international norms. The regulations are overseen by the Civil Aviation Safety Authority (CASA), which is tasked with enforcing compliance and ensuring that aircraft meet stringent safety standards. The overarching policy objective of these regulations is to maintain the highest possible levels of safety in civil aviation by prescribing detailed requirements for the design, production, maintenance, and operation of aircraft. This includes issuing specific directives such as Airworthiness Directives (ADs) that mandate corrective actions to address identified safety issues.

Scope and Application

The Civil Aviation Regulations 1998, as amended, encompass the specific scope and application of the Airworthiness Directives (AD) in relation to certain Auster/Beagle A.61 Series Aeroplanes. The legislation applies to models J5F, J5K, J5L, J1, J1B, J2, J4, J5, J5B, J5G, J5H, J5P, Mark VD, and Civil Marks IV and V, as well as Model Mark III. This regulation mandates the removal of the ball and socket assembly of the aileron control push rods and the fitting of redesigned rod end bearings according to specified modifications and drawings. The requirement to comply with these directives is immediate, ensuring that the airworthiness of these aeroplanes is maintained to the highest safety standards. The directive is issued under the authority of the Civil Aviation Safety Authority, ensuring its application across the Commonwealth of Australia, thereby affecting all relevant operators and entities within the national jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains the Civil Aviation Safety Authority Schedule of Airworthiness Directives for various aircraft types. In this instance, AD/AUS/4 pertains to Auster/Beagle A.61 Series Aeroplanes, focusing on the aileron control push rod. The directive applies to several models of the Auster/Beagle A.61 Series, including J5F, J5K, J5L, J1, J1B, J2, J4, J5, J5B, J5G, J5H, J5P, Mark VD, and Civil Marks IV and V, as well as Model Mark III (1). The requirement outlined in the directive is to remove the existing ball and socket assembly of the aileron control push rods and fit redesigned rod end bearings. This must be done according to Auster Modification 2893 for certain models, Auster Modification No. 2895 or DCA Drawing No. HH.3338 for others, and strictly following DCA Drawing No. HH.3338 for Model Mark III (1). Entities governed by these regulations must adhere to the specifications provided within the directive to ensure compliance. This involves a thorough inspection of the aileron control push rods and their assemblies. The necessary modifications must be carried out forthwith, with the ball and socket assembly removed and replaced with the redesigned rod end bearings as per the appropriate modification or drawing specified in the directive. The directive underscores the importance of precise adherence to the outlined procedures to maintain the airworthiness of the affected aircraft models. Failure to comply with the requirements set forth in the Civil Aviation Regulations 1998, Part 39 - 105, can result in severe consequences. The regulatory framework is designed to ensure the safety and integrity of civil aviation, and non-compliance can lead to significant penalties. Specifically, breaches of airworthiness directives can lead to enforcement actions, including fines, grounding of the aircraft, or other punitive measures. The exact penalties for non-compliance are not detailed within the directive itself but are generally severe, reflecting the critical nature of maintaining airworthiness standards in aviation.
