COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Aerospatiale (Socata) TB9 and TB10 (Tobago) Series Aeroplanes
AD/TB10/36 Nose Gear Fork 10/2003
Applicability: Model TB 9 and TB 10 aircraft, serial numbers 2054, 2074 through 2155, and 2184. Requirement: Action in accordance with Socata Service Bulletin TB No. 10-138, dated May 2003.
Note: DGAC AD 2003-285(A) refers.
Compliance: At the next major inspection after 2 October 2003 or before 31 December 2003, whichever occurs first.
This Airworthiness Directive becomes effective on 2 October 2003.
Background: This Directive requires inspection of the nose gear fork grain structure, due to the possibility of inverted material grain flow which may have occurred as a result of an incorrect manufacturing process.

The above AD is notified in the Commonwealth of Australia Gazette on 10 September 2003.
Overview
The Civil Aviation Safety Regulations 1998 (CASR) were enacted to ensure the safety and efficiency of civil aviation in Australia. This comprehensive set of regulations, administered by the Civil Aviation Safety Authority (CASA), addresses various aspects of civil aviation safety, including aircraft maintenance, pilot qualifications, and operational standards. The regulations were established to fill the need for a cohesive and authoritative framework governing the safety of civil aviation within Australia, thereby safeguarding the public, aircraft, and crew. The CASR were enacted by the Parliament of the Commonwealth of Australia, with the primary policy objective being to maintain the highest possible standards of safety in the operation of civil aircraft. The regulations are designed to provide a robust and flexible regulatory environment that can adapt to the evolving nature of the aviation industry while prioritising safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, particularly under PART 39 - 105 and the Airworthiness Directives, apply to specific models of aircraft manufactured by Aerospatiale (Socata), namely the TB9 and TB10 (Tobago) Series Aeroplanes, with particular serial numbers specified in the directive. This legislation, issued by a delegate of the Civil Aviation Safety Authority (CASA), mandates corrective actions to address identified safety concerns regarding the nose gear fork grain structure, which may have resulted from an incorrect manufacturing process. The directive applies to aircraft owners or operators who must comply with the specified requirements, including inspecting the nose gear fork in accordance with Socata Service Bulletin TB No. 10-138. The geographical scope of this directive is nationwide, aligning with Australia's federal structure and the overarching authority of CASA. The directive is effective from 2 October 2003, and compliance is required at the next major inspection after this date or before 31 December 2003, whichever comes first. This Airworthiness Directive is further enforced through notification in the Commonwealth of Australia Gazette on 10 September 2003.
Key Provisions
The main operative sections of the Civil Aviation Safety Regulations 1998, Part 39 - 105, pertain to Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). Section 39.105, specifically AD/TB10/36, mandates that certain Aerospatiale (Socata) TB9 and TB10 (Tobago) series aeroplanes undergo an inspection of their nose gear fork grain structure. The directive references Socata Service Bulletin TB No. 10-138, dated May 2003, which provides the specific instructions for the inspection. This directive applies to aircraft with serial numbers 2054, 2074 through 2155, and 2184. The compliance requirement stipulates that the inspection must be carried out at the next major inspection following 2 October 2003 or before 31 December 2003, whichever comes first.
The obligations imposed by this AD on the parties or entities it governs are clear and specific. Aircraft operators and maintenance providers must ensure that the nose gear fork of the specified TB9 and TB10 aircraft is inspected for inverted material grain flow as per the guidelines in Socata Service Bulletin TB No. 10-138. This inspection must be performed at the next major inspection following 2 October 2003, or before the end of 2003, ensuring the safety and airworthiness of these aircraft. Failure to comply with these requirements could result in the aircraft being deemed unsafe to fly, leading to potential grounding and further regulatory action.
The consequences for non-compliance with this Airworthiness Directive are significant. While the regulations themselves do not explicitly state the civil or criminal penalties for non-compliance, failure to adhere to ADs can result in severe repercussions. These can include fines, operational restrictions, and potential criminal charges for endangering public safety. Additionally, aircraft found to be non-compliant could be grounded, preventing them from flying until the necessary actions are taken to rectify the issue. The overarching goal of these provisions is to ensure the safety of the aircraft and its occupants by mandating timely and thorough inspections.
