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.
British Aerospace BAe 3100 (Jetstream) Series Aeroplanes
AD/JETSTREAM/91 Main Landing Gear Radius Rods 10/2001
DM
Applicability: All Jetstream 3100 and 3200 Series aircraft with radius rods part numbers 1847/A through /L (left) and 1862/A through /L (right) installed.
Requirement: Action in accordance with BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2.
Note: For aircraft on which the Requirement document at original issue has already been accomplished, Revision 2 may require further work to mark affected radius rods with a date for their removal from service.
Compliance: Before 22 September 2001, unless already accomplished.
This Airworthiness Directive becomes effective on 22 August 2001.
Background: Due to an error in the manufacturing process the material of some radius rod cylinders, part number 184811, may not have received the correct heat treatment. This condition can result in failure of the radius rod and collapse of the landing gear during an abnormal event, such as a heavy landing.

Overview
The Civil Aviation Regulations 1998 (CAR 1998), enacted by the Commonwealth of Australia, aim to ensure the safety and efficiency of civil aviation operations within the country. Part 39, specifically Airworthiness Directive 105, addresses issues related to the airworthiness of aircraft and aeronautical products, establishing standards and requirements to maintain safety in the aviation industry. The Civil Aviation Safety Authority (CASA), as a delegate of the Commonwealth, issues these directives to address specific safety concerns, such as the one identified in Airworthiness Directive AD/JETSTREAM/91. This directive targets the British Aerospace BAe 3100 (Jetstream) Series Aeroplanes, addressing a manufacturing defect in the main landing gear radius rods. The problem identified was due to an error in the manufacturing process, which could result in the failure of the radius rods and potential collapse of the landing gear during abnormal events. The directive mandates corrective actions, as outlined in BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2, to ensure that affected aircraft meet the necessary safety standards before a specified compliance date.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39, governs the Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft within Australia. This particular AD, numbered AD/JETSTREAM/91, applies to all Jetstream 3100 and 3200 Series aircraft equipped with main landing gear radius rods bearing part numbers 1847/A through /L (left) and 1862/A through /L (right). The directive mandates that corrective action be taken in accordance with BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2, with compliance required before 22 September 2001. The directive addresses a manufacturing defect in certain radius rod cylinders that may not have undergone the correct heat treatment, potentially leading to failures and safety hazards during abnormal landing events. The AD became effective on 22 August 2001, following its notification in the Commonwealth of Australia Gazette.
Key Provisions
The Airworthiness Directive (AD/JETSTREAM/91) issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 (CAR 1998) mandates specific actions to address an identified unsafe condition in British Aerospace BAe 3100 (Jetstream) Series aeroplanes. According to the AD, the action specified in the requirement section must be carried out for all Jetstream 3100 and 3200 Series aircraft equipped with radius rods of certain part numbers (1847/A through /L for left rods and 1862/A through /L for right rods) before 22 September 2001. The directive specifies that the action should align with the instructions detailed in BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2, which may necessitate further work to mark affected radius rods with a date for their removal from service if the original requirement has already been met.
The obligations imposed by this AD on the relevant parties include ensuring that the actions outlined in the requirement section are undertaken without delay, adhering strictly to the instructions provided in the Alert Service Bulletin. Specifically, this involves following the procedures and guidelines set out in BAE Systems Alert Service Bulletin ASB 32-A-JA010740 Revision 2 to address potential issues with the radius rods, which may otherwise lead to landing gear failure during abnormal events such as heavy landings.
Failure to comply with this Airworthiness Directive can result in serious safety implications, as the AD is designed to correct a condition that can lead to catastrophic failure of the aircraft's landing gear. Although the Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with ADs, the non-compliance could lead to severe civil or criminal consequences, including potential enforcement actions by the Civil Aviation Safety Authority (CASA). The authority may impose penalties, including fines, and could suspend or revoke the airworthiness certificate of the aircraft, rendering it unable to fly until the required actions are satisfactorily completed.
