Overview

The Civil Aviation Safety Regulations 1998, enacted by the Commonwealth of Australia's Parliament, aim to ensure the safety of civil aviation operations within Australia. These regulations provide a framework for the administration of civil aviation safety, including the issuance of airworthiness directives to address safety issues. One such directive, AD/TB10/33, was issued by the Civil Aviation Safety Authority (CASA) on 24 August 2001, in response to a fault identified in the manufacturing process of nose gear forks for Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes. The directive requires that specific corrective action be taken on affected aircraft to address the unsafe condition, ensuring compliance with Socata Service Bulletin SB 10-120-32 and mandating that the necessary maintenance be completed by 31 March 2002. The policy objective of this directive is to mitigate safety risks by mandating timely and specific corrective actions to rectify known manufacturing faults in aircraft components.

Scope and Application

The Airworthiness Directive (AD) issued under the Civil Aviation Safety Regulations 1998 applies specifically to Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes that have nose gear forks delivered as spare parts by Socata between 1 January 1999 and 28 February 2001. This AD mandates corrective action to address a fault in the nose gear fork manufacturing process, as outlined in Socata Service Bulletin SB 10-120-32, dated June 2001. The directive requires that the specified action be taken in accordance with the instructions provided and must be completed at the next scheduled maintenance visit after 4 October 2001 or before 31 March 2002, whichever is earlier. This AD, issued by a delegate of the Civil Aviation Safety Authority, became effective on 4 October 2001 and was published in the Commonwealth of Australia Gazette on 12 September 2001.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) include provisions for Airworthiness Directives (ADs), which are regulatory requirements that aim to correct unsafe conditions in specific aircraft or aeronautical products. Section 39.1(1) allows the Civil Aviation Safety Authority (CASA) delegate to issue such directives. An example of an AD is AD/TB10/33, which pertains to Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes. This directive applies to TB9 and TB10 aircraft equipped with nose gear forks delivered as spare parts by Socata between 1 January 1999 and 28 February 2001. The directive mandates that the action specified in Socata Service Bulletin SB 10-120-32, dated June 2001, must be undertaken. This action is intended to address a fault identified in the manufacturing process of the nose gear forks. It is noteworthy that this directive corresponds to DGAC AD 2001-305(A). Compliance with this AD requires that the specified action be taken during the next scheduled maintenance visit after 4 October 2001, but no later than 31 March 2002. The obligations imposed by this AD on the relevant parties include ensuring that the specified action, as outlined in the Socata Service Bulletin, is carried out on the affected aircraft within the stipulated timeframe. This involves reviewing the maintenance records, sourcing the necessary parts or modifications, and executing the corrective action as per the instructions provided. Additionally, operators and maintenance personnel must be adequately informed and trained to understand the requirements of the AD and to perform the mandated actions accurately and effectively. Failure to comply with this AD could result in the aircraft being deemed unairworthy, which would prevent its operation until the necessary corrective measures are implemented. The AD also specifies consequences for non-compliance. Any breach of this directive could lead to civil or criminal penalties, depending on the severity of the violation. In cases of civil non-compliance, the penalties can include fines or other financial penalties as determined by the regulatory authority. Criminal penalties may also apply if the breach results in serious safety hazards or if it is found that the operator wilfully disregarded the directive. The maximum penalties for such breaches are not explicitly stated in the AD but are generally governed by the broader provisions of the Civil Aviation Act 1988 and related regulations, which can include significant fines and imprisonment for individuals found guilty of serious safety violations.
