Overview
The Civil Aviation Safety Authority (CASA) enacted the Airworthiness Directive AD/BAe 146/61 Amdt 2 in 2003, addressing stress corrosion cracking on the top wing skin of British Aerospace BAe 146 series aeroplanes. This directive, which came into effect on 2 October 2003, was issued in response to reports of stress corrosion cracking identified during routine inspections, highlighting a significant safety concern. The objective of the directive is to ensure the ongoing airworthiness of the affected aircraft by mandating specific inspection procedures in accordance with BAE Systems Mandatory Service Bulletin 57-49 Revision 2. The directive specifies the aircraft models subject to the requirement and outlines the compliance timeline, ensuring that the identified safety issue is effectively managed.
Scope and Application
The Airworthiness Directive (AD) issued under F2006B03511 applies specifically to certain models of BAe 146 Series and Avro 146 aircraft, namely BAe 146 Series 100 aircraft with serial numbers E1144 and subsequent, Series 200 aircraft from E2148 onwards, and Series 300 aircraft from E3141 onwards, as well as Avro 146-RJ70 Series aircraft with serial numbers between E1223 and E1267, Avro 146-RJ85 Series aircraft with serial numbers between E2208 and E2277, and E2288, and Avro 146-RJ100 Series aircraft with serial numbers between E3221 and E3276, and E3282, E3283, E3284, and E3286. This AD mandates inspections for stress corrosion cracking in accordance with BAE Systems Mandatory Service Bulletin 57-49 Revision 2, reflecting an update to the original directive issued on 12 September 1996 and amended on 9 October 1997. The directive, which was revoked and reissued, is applicable within the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority (CASA). Compliance with the AD must be achieved by following the specified inspection requirements as outlined in the relevant service bulletin, with the directive becoming effective from 2 October 2003.
Key Provisions
The Airworthiness Directive (AD) AD/BAe 146/61 Amdt 2 pertains specifically to the British Aerospace BAe 146 Series aeroplanes, including various series and models. The AD mandates that all BAe 146 Series 100 aircraft from E1144 onwards, Series 200 aircraft from E2148 onwards, and Series 300 aircraft from E3141 onwards, as well as certain Avro 146-RJ Series aircraft, must undergo inspections to address stress corrosion cracking on the top wing skin (section 10/2003). This directive is an amendment to the original AD, which was issued on 12 September 1996, and it further refines the applicability of the directive, as clarified in Amendment 1 from 9 October 1997.
The directive outlines that the inspections must be conducted in accordance with BAE Systems Mandatory Service Bulletin 57-49 Revision 2, referencing the UK Civil Aviation Authority AD 005-06-96 for further details (section Requirement). The inspections are to be performed as specified within the Requirement document, and the compliance period is also detailed in this document. The AD became effective on 2 October 2003, superseding the previous amendments.
Entities governed by this AD must ensure that the specified inspections are carried out on the affected aircraft within the stipulated timeframes, as detailed in the Requirement document. Failure to comply with the AD's requirements could result in the aircraft being deemed non-airworthy, thereby prohibiting flight until the necessary actions are completed. Non-compliance with airworthiness directives can lead to serious legal and safety repercussions, including potential fines, enforcement actions, or other penalties as prescribed by aviation regulations.
Any breaches of the AD may result in civil or criminal consequences, depending on the severity of the violation. The Civil Aviation Safety Authority (CASA) has the authority to enforce the AD and may impose fines or other penalties for non-compliance. The maximum penalties for such breaches are not explicitly stated in the AD but are typically governed by the broader regulatory framework under which CASA operates. The potential penalties may include substantial fines, suspension or revocation of aircraft operation permits, or other regulatory actions as deemed appropriate by CASA.
