AIRWORTHINESS DIRECTIVE
On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/JETSTREAM/97 and issues the following 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.
British Aerospace BAe 3100 (Jetstream) Series Aeroplanes
AD/JETSTREAM/97
Amdt 1
Fuselage and Wing Structure Fatigue Damage - 1
10/2004
Applicability: All Model Jetstream Series 3200 aircraft.
Requirement: Inspect in accordance with BAE Systems Mandatory Service Bulletin (SB) 51- JA020940 Revision 1 or later EASA approved edition.
The original issue of the Requirement document contained a typographical error. If a detailed visual inspection was performed with the windows removed then full credit can be taken for the accomplishment of the initial inspection. If a detailed visual inspection was performed with the windows installed, the clarified NDI task stated in Revision 1 of the Requirement document, Appendix 1, Paragraph M, Part 14, must be performed before 1 July 2005. Thereafter, all subsequent window pan inspections are to be accomplished on or before the repeat interval stated in the Requirement document.
Note: UK CAA AD G-2004-0017 refers.
Compliance: At the initial and repeat inspection times specified in the Requirement document.
New requirements introduced by SB 51-JA020940 Revision 1, are stated in Paragraph M - Approval, Appendix 2, Part 1. For the tasks defined in SB 51-020940 Revision 1, Appendix 1, Paragraph M, Parts 14 and 15, where the initial inspection interval is stated as 25,800 landings or 10 years, the requirement: whichever occurs first, is to apply. Where the repeat inspection interval is stated as: 4,400 landings or 2 years, the requirement: whichever occurs first, is to apply. Where the inspection interval is stated as: 4,400 landings or D check, this is to be read as: 4,400 landings or 2 years, whichever occurs first.
This Amendment becomes effective on 30 September 2004.
Background: An extensive review of the results of the wing fatigue test and aircraft life extension investigation has been completed for Jetstream 3200 aircraft. This Directive introduces new and revised inspections of the fuselage and wing structure for fatigue damage.

AD/JETSTREAM/97 Amdt 1 (continued)
Amendment 1 is issued in response to a new CAA AD, which introduces a revision of the Requirement document with revised inspection techniques deemed necessary to adequately accomplish certain inspection tasks, and to specify grace periods applicable for aircraft that have exceeded the initial inspection thresholds.

The above AD is notified in the Commonwealth of Australia Gazette on 8 September 2004.
Overview
The Airworthiness Directive (AD) AD/JETSTREAM/97 Amendment 1, enacted by the Civil Aviation Safety Authority (CASA) in 2004, is a legislative instrument aimed at addressing safety concerns related to the British Aerospace BAe 3100 (Jetstream) Series 3200 aircraft. This AD was introduced in response to the need for revised inspection techniques and grace periods for certain inspections of the fuselage and wing structure of Jetstream 3200 aircraft, following the completion of a comprehensive review of the results of the wing fatigue test and aircraft life extension investigation. The policy objective of this AD is to ensure the airworthiness of the affected aircraft by implementing necessary safety measures and inspections as specified in the BAE Systems Mandatory Service Bulletin 51-JA020940 Revision 1 or later EASA approved edition. The AD becomes effective on 30 September 2004, and the compliance requirements must be met at the initial and repeat inspection times specified in the Requirement document.
Scope and Application
The Airworthiness Directive issued under the Civil Aviation Safety Regulations 1998 applies specifically to all British Aerospace BAe 3100 (Jetstream) Series 3200 aeroplanes. This directive mandates inspections to address fatigue damage in the fuselage and wing structures, replacing the previously issued AD/JETSTREAM/97. The directive requires that inspections be conducted in accordance with the specified BAE Systems Mandatory Service Bulletin 51-JA020940 Revision 1 or a later EASA approved edition. It mandates these inspections to be carried out at both the initial and subsequent intervals as outlined in the bulletin, which include conditions based on either the number of landings or the passage of time. The directive is effective from 30 September 2004 and applies nationally within the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA). The directive includes specific provisions for compliance and amendments, clarifying inspection requirements and establishing grace periods for aircraft that have surpassed the initial inspection thresholds.
Key Provisions
The Airworthiness Directive (AD) AD/JETSTREAM/97 Amdt 1 applies to all Model Jetstream Series 3200 aircraft. The directive mandates specific inspections of the fuselage and wing structure to address fatigue damage, as outlined in the requirement section. The requirement stipulates that these inspections must be conducted in accordance with BAE Systems Mandatory Service Bulletin (SB) 51-JA020940 Revision 1 or a later edition approved by EASA. The compliance section specifies that these inspections must occur at the initial and subsequent inspection times detailed in the requirement document.
Entities governed by this AD must adhere to the inspection protocols as described in the requirement section. They must ensure that inspections are performed with or without the aircraft windows, as specified in the requirement document, and must complete the necessary tasks before the specified deadlines. Notably, if a detailed visual inspection was performed with the windows removed, it can be fully credited towards the initial inspection requirement. However, if the inspection was performed with the windows installed, additional tasks as outlined in Revision 1 of the requirement document must be completed by 1 July 2005.
Failure to comply with the AD may result in serious safety implications, potentially leading to the aircraft being deemed unairworthy. Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against non-compliance. These actions could include imposing fines, imposing operational restrictions on the aircraft, or even grounding the aircraft until the required inspections are satisfactorily completed. The severity of the penalties may depend on the extent and impact of the non-compliance on aviation safety.
