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.
Saab SF340 Series Aeroplanes
AD/SF340/85 Propeller Remote Controlled Circuit Breakers 5/2002
Applicability: Model 340B aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers.
Requirement: If not previously accomplished, inspect Remote Controlled Circuit Breakers (RCCB) 29KFC and 30KFC to ensure that Part Number (P/N) M83383-01-09 (50 Amp) circuit breakers are installed. If an incorrect P/N RCCB is installed, replace the RCCB with a P/N M83383-01-09 circuit breaker. The above actions are to be accomplished in accordance with Saab Aircraft AB Service Bulletin 340-61-038 dated 30 January 2002.
Note: LFV AD 1-172 refers.
Compliance: Before 31 July 2002.
This Airworthiness Directive becomes effective on 16 May 2002.
Background: All 340B aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers have 50 Amp RCCBs installed during production, but the IPC refers to 35 Amp RCCB which are specific to Dowty propellers. The inspection is required to ensure the correct RCCB is installed, thus providing the correct circuit protection for the propeller feather pump system on aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers.

The above AD is notified in the Commonwealth of Australia Gazette on 24 April 2002.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were established to regulate all aspects of civil aviation, including ensuring the airworthiness of aircraft. In 2002, the Civil Aviation Safety Authority (CASA) introduced Airworthiness Directive AD/SF340/85 to address a safety issue specific to Saab SF340 Series aeroplanes. This directive was necessary to rectify an unsafe condition where the incorrect type of Remote Controlled Circuit Breaker (RCCB) was potentially installed in certain aircraft, leading to inadequate circuit protection for the propeller feather pump system. The directive required operators of Model 340B aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers to inspect and, if necessary, replace the RCCBs to ensure compliance with safety standards. The policy objective behind this directive was to maintain and enhance the safety of air operations by correcting potential safety hazards identified in specific aircraft models.
Scope and Application
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, mandate that the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) to ensure the safety of aircraft and aeronautical products. These directives apply to specific types of aircraft and are enforced by CASA delegates. The AD for Saab SF340 Series aeroplanes, identified as AD/SF340/85, applies to Model 340B aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers. The directive mandates that if not previously accomplished, the Remote Controlled Circuit Breakers (RCCB) 29KFC and 30KFC must be inspected to ensure the correct Part Number (P/N) M83383-01-09 (50 Amp) circuit breakers are installed. If incorrect RCCBs are found, they must be replaced with the specified ones in accordance with Saab Aircraft AB Service Bulletin 340-61-038 dated 30 January 2002. This directive applies nationwide within the Commonwealth of Australia and must be complied with before 31 July 2002. The AD becomes effective from 16 May 2002 and is intended to correct the unsafe condition related to the circuit protection of the propeller feather pump system on aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) concerning Saab SF340 Series aeroplanes. The AD mandates that certain actions be taken for Model 340B aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers (s 39.1). The AD requires that the Remote Controlled Circuit Breakers (RCCB) 29KFC and 30KFC are inspected to ensure the correct Part Number (P/N) M83383-01-09 (50 Amp) circuit breakers are installed (s 39.105). If an incorrect RCCB is found, it must be replaced with the correct P/N M83383-01-09 circuit breaker, following Saab Aircraft AB Service Bulletin 340-61-038 dated 30 January 2002 (s 39.105).
The obligations under this AD include conducting the specified inspection and any necessary replacement of RCCBs on the specified aeroplane models before the compliance date, which is 31 July 2002. The directive mandates adherence to the instructions provided in the service bulletin to ensure the correct circuit protection for the propeller feather pump system on aeroplanes equipped with Hamilton Sunstrand (Hamilton Standard) propellers (s 39.105). Failure to comply with the AD could result in safety risks associated with the incorrect circuit protection, potentially leading to system failures during operation.
The AD does not explicitly state the penalties or consequences for non-compliance, but non-compliance with ADs issued under the Civil Aviation Regulations 1998 is generally subject to enforcement actions by CASA. These actions may include fines, the grounding of the aircraft until compliance is achieved, and other regulatory sanctions. The severity of these penalties depends on the nature and extent of the non-compliance, as well as any resulting safety risks. CASA may take further action, including pursuing criminal charges if the non-compliance is deemed to be of a serious nature and results in safety hazards.
