COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Beechcraft 55, 58 and 95-55 (Baron) Series Aeroplanes
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.
AD/BEECH 55/87 Rudder Control System 2/2001 DM
Applicability: Model 58 aircraft, serial numbers TH-1576 through TH-1838.
Requirement: Inspect rudder control system in accordance with the Accomplishment Instructions of Raytheon Mandatory Service Bulletin 27-3265, Issued January 2000; and the applicable aircraft Maintenance Manual or Shop Manual.
Note: FAA AD 2000-24-04 Amdt 39-12011 refers.
Compliance: Within 50 hours’ time in service after 17 January 2001, unless already accomplished.
This Airworthiness Directive becomes effective on 17 January 2001.
Background: The FAA received three reports of misrouted rudder control cables in which the control cables were routed over the cable guard pins rather than between the cable guard pins and the cable pulleys. This condition could result in guard pin wear and separation or fraying of the cables with loss of rudder control.

The above AD is notified in the Commonwealth of Australia Gazette on 17 January 2001.
Overview
The Civil Aviation Regulations 1998, introduced by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation in the country. One of the critical components of this framework is the issuance of Airworthiness Directives (ADs) by the Civil Aviation Safety Authority (CASA) to address specific safety concerns in aircraft operations. An example of such a directive is AD/BEECH 55/87, which was issued on 17 January 2001 to address a safety issue with the rudder control system in certain Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes. This AD was introduced in response to reports of misrouted rudder control cables, which could lead to wear and potential separation of guard pins or fraying of the cables, thereby risking loss of rudder control. The directive mandates inspections and corrective actions to mitigate this risk, ensuring the continued safe operation of affected aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) concerning the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes. This directive applies to Model 58 aircraft with serial numbers ranging from TH-1576 to TH-1838. The directive mandates an inspection of the rudder control system in accordance with Raytheon Mandatory Service Bulletin 27-3265 issued in January 2000, and applicable aircraft Maintenance Manual or Shop Manual. This action must be completed within 50 hours of time in service after the directive's effective date of 17 January 2001, unless it has already been performed. The directive was prompted by reports of misrouted rudder control cables, which could lead to significant safety issues such as guard pin wear, separation, or fraying of the cables, resulting in a potential loss of rudder control. The AD is applicable nationwide within the Commonwealth of Australia and is enforced by CASA, with the authority to delegate certain tasks to authorised personnel.
Key Provisions
The Civil Aviation Regulations 1998 (CAR) establish a comprehensive regulatory framework for civil aviation safety in Australia. Specifically, Part 39 of the regulations includes detailed provisions for ensuring the airworthiness of aircraft, and under this section, the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (AD) to address identified safety issues. Section 39.1 (1) empowers CASA to issue ADs to correct unsafe conditions in aircraft or aeronautical products. In this case, AD/BEECH 55/87 pertains to the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes and focuses on the rudder control system (section 2/2001 DMApplicability).
AD/BEECH 55/87 mandates that owners and operators of Model 58 aircraft with serial numbers ranging from TH-1576 to TH-1838 must inspect the rudder control system. The inspection must adhere to the Accomplishment Instructions outlined in Raytheon Mandatory Service Bulletin 27-3265, issued in January 2000, and the applicable aircraft Maintenance Manual or Shop Manual. This requirement is critical as it aims to rectify a condition where rudder control cables could become misrouted, potentially leading to guard pin wear, cable separation, or fraying, which could result in the loss of rudder control. The directive explicitly references FAA AD 2000-24-04 Amdt 39-12011 for further context.
The obligations imposed by this AD are clear and specific. Aircraft owners and operators must ensure that the inspection of the rudder control system is performed within 50 hours of time in service after the AD’s effective date of 17 January 2001, unless the inspection has already been accomplished. Failure to comply with these requirements can have significant consequences. Non-compliance with ADs can result in severe safety risks, including potential loss of control over the aircraft. In terms of regulatory enforcement, violations of ADs can lead to enforcement actions, including fines and potential criminal charges under section 14 of the Civil Aviation Act 1988, which may result in penalties of up to $165,294 for corporations and $33,058 for individuals, as well as imprisonment for up to five years.
