Overview

The Civil Aviation Regulations 1998, specifically within Part 39, encompasses various directives aimed at ensuring the safety and airworthiness of aircraft within Australian airspace. Among these is the Airworthiness Directive (AD) AD/CASA/23 concerning the CASA 212 series aeroplanes. Enacted to address the problem of excessive wear in the spherical bearings of the aileron command bar, which has been linked to inadequate retaining washers, this AD was introduced to mitigate the risk of bearing displacement from their housings. The Australian Government, through the Civil Aviation Safety Authority (CASA), established this directive to ensure compliance within 100 hours of time in service after 15 August 1996, thereby enhancing the safety and operational reliability of the affected aircraft. The policy objective is to maintain high safety standards and prevent potential hazards that could compromise flight safety.

Scope and Application

The Civil Aviation Safety Authority Regulations 1998, specifically Part 39 - 105, apply to all CASA 212 Series aeroplanes and require compliance with Airworthiness Directive AD/CASA/23, which pertains to the aileron control rod movable joint. This regulation is applicable across the Commonwealth of Australia and governs the safety and operational standards of the specified aircraft models. Compliance with this directive is mandatory for all operators of CASA 212 Series aeroplanes, with the action required to be taken in accordance with CASA Service Bulletin SB 212-27-48. This directive mandates that any identified issues with the spherical bearings of the aileron command bar, particularly excessive wear due to inadequate retaining washers, must be rectified within 100 hours of time in service after 15 August 1996. Failure to adhere to these requirements could result in non-compliance with national aviation safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) for Casa 212 series aeroplanes. The directive, identified as AD/CASA/23, pertains to the aileron control rod movable joint (section 9/96). The directive applies to all models of the Casa 212 series aeroplanes and mandates action in accordance with CASA Service Bulletin 212-27-48. The directive notes that a similar action has been taken by the Spanish Directorate General of Civil Aviation (DGAC), as referenced in AD 05/96. The requirement is for compliance within 100 hours of time in service after 15 August 1996, due to issues of excessive wear in the spherical bearings of the aileron command bar at the base of the control column. This wear is caused by inadequate retaining washers and may lead to the displacement of the bearings from their housings. Entities governed by the Civil Aviation Regulations 1998 must adhere to the requirements set out in AD/CASA/23. This involves taking action as specified in CASA Service Bulletin 212-27-48 within the stipulated timeframe of 100 hours of time in service after 15 August 1996. Failure to comply with this directive could result in the aeroplanes not meeting the required airworthiness standards, potentially leading to safety hazards and regulatory non-compliance. It is crucial for operators to ensure that the spherical bearings of the aileron command bar are inspected and, if necessary, repaired or replaced to prevent the bearings from becoming displaced from their housings. Breach of the requirements outlined in AD/CASA/23 may result in civil or criminal consequences. While specific penalties are not detailed in the directive itself, non-compliance with Civil Aviation Regulations 1998 can lead to enforcement actions by the Civil Aviation Safety Authority. Potential consequences may include fines, operational restrictions, or even the grounding of the affected aircraft until the necessary actions are taken to rectify the issue. It is imperative for operators to take the directive seriously and ensure timely compliance to avoid any adverse outcomes.
