COMMONWEALTH OF AUSTRALIA (Civil Aviation 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 CAR 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 (Tabago) Series Aeroplanes
AD/TB10/34 Ammeter Electrical Circuit 12/2001 DM
Applicability: All Model TB9 and TB10 aeroplanes equipped with ammeter options OPT 10 593 00M, OPT 10 689 00M or OPT D689 00M.
Requirement: Modify the ammeter electrical circuit in accordance with Socata Mandatory Service Bulletin TB Aircraft 10-122-24 dated July 2001.
Note: DGAC AD 2001-446(A) refers.
Compliance: At the next scheduled maintenance check, but no later than 31 December 2001.
This Airworthiness Directive becomes effective on 24 October 2001.
Background: The French Direction Générale de L’Aviation Civile has advised that in-flight failures of the ammeter electrical circuit have been reported to Socata. These failures could result in smoke or a burning smell in the cockpit. This Directive requires modification of the ammeter electrical circuit.

Delegate of the Civil Aviation Safety Authority 17 October 2001
The above AD is notified in the Commonwealth of Australia Gazette on 24 October 2001.
Overview
The Civil Aviation Regulations 1998, established by the Australian Parliament, govern civil aviation safety within Australia. Specifically, Part 39, which includes the 105th Airworthiness Directive, addresses safety concerns through regulatory measures. This directive was enacted to address the issue of in-flight failures of the ammeter electrical circuit in Aerospatiale (Socata) TB9 and TB10 aeroplanes, which could lead to safety hazards such as smoke or a burning smell in the cockpit. The Civil Aviation Safety Authority (CASA) issued this directive under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 to ensure the necessary modifications to the ammeter electrical circuit are implemented to maintain aircraft safety. The directive mandates compliance by the next scheduled maintenance check but no later than 31 December 2001, as per the notification in the Commonwealth of Australia Gazette on 24 October 2001.
Scope and Application
The Civil Aviation Regulations 1998, particularly PART 39 - 105, applies to all persons and entities involved in the operation and maintenance of civil aircraft within Australia. This includes individuals, aviation companies, maintenance organisations, and aircraft manufacturers. The regulations extend to all types of civil aviation activities, ensuring compliance with safety standards and directives issued by the Civil Aviation Safety Authority (CASA). The geographic reach of these regulations is national, applying uniformly across Australia, including its territories. Any exemptions or thresholds are typically outlined in specific Airworthiness Directives, such as AD/TB10/34, which targets certain aircraft models and configurations. This AD, issued under subregulation 39.1 (1) of CAR 1998, applies to all Aerospatiale (Socata) TB9 and TB10 (Tabago) Series aeroplanes equipped with specific ammeter options. The directive mandates modifications to the ammeter electrical circuit to address potential in-flight failures that could cause smoke or a burning smell in the cockpit. The AD becomes effective from 24 October 2001, and compliance must be achieved by 31 December 2001, or at the next scheduled maintenance check.
Key Provisions
The Airworthiness Directive (AD) under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) mandates specific actions to rectify an unsafe condition in certain aircraft models. Specifically, AD/TB10/34 targets Aerospatiale (Socata) TB9 and TB10 (Tabago) Series aeroplanes equipped with particular ammeter options (sections 1, 2). The directive necessitates modifying the ammeter electrical circuit in accordance with Socata Mandatory Service Bulletin TB Aircraft 10-122-24 dated July 2001 (section 3). This modification is intended to prevent in-flight failures that could lead to smoke or a burning smell in the cockpit.
This AD imposes obligations on aircraft operators and maintenance personnel to ensure compliance with the specified requirements. Operators must adhere to the directive by modifying the ammeter electrical circuit as outlined in the Socata Service Bulletin, which involves updating or repairing the electrical circuit to prevent potential hazards (section 3). Compliance must be achieved at the next scheduled maintenance check, but no later than 31 December 2001 (section 4). Failure to comply with the AD could result in safety risks and potential legal consequences.
Failure to comply with the Airworthiness Directive can lead to serious safety concerns and potential regulatory repercussions. The directive specifies that non-compliance may result in the aircraft being deemed unairworthy. Civil Aviation Safety Authority (CASA) may take enforcement actions against operators who fail to adhere to the AD. The consequences can include fines, operational restrictions, or grounding of the aircraft until the required modifications are completed. The maximum penalties for non-compliance with ADs under the Civil Aviation Act 1988 can include fines up to $22,200 for individuals and $111,000 for corporations, reflecting the serious nature of ensuring airworthiness standards.
