AD/SD3-60/44 - Strobe Lighting

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, provide a comprehensive framework for the regulation of civil aviation within Australia. Among these regulations, Part 39, particularly 105, addresses the safety directives related to aircraft airworthiness. Specifically, AD/SD3-60/44 pertains to strobe lighting for SD3-60-200 variant aeroplanes, aiming to ensure that these aircraft meet the minimum intensity certification requirements for tail strobe lights. This directive was introduced to rectify deficiencies identified by the UK's Civil Aviation Authority (CAA), which indicated that the existing tail strobe light did not comply with necessary safety standards. The policy objective is to enhance the safety of civil aviation by mandating the incorporation of Modification No A8651, which includes a new strobe light and power supply, in line with the specifications outlined in Shorts Service Bulletin SD360-33-25 Revision 1 dated July 1996. Compliance with this directive is required prior to 31 March 1997.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically targeting SD3-60-200 variant aeroplanes. This directive mandates the incorporation of Modification No A8651, which includes the introduction of a new strobe light and power supply with associated hardware, in accordance with Shorts Service Bulletin SD360-33-25 Revision 1 dated July 1996. This directive is applicable to all SD3-60-200 variant aeroplanes and requires compliance by 31 March 1997. The directive is based on a recommendation from the UK's Civil Aviation Authority (CAA) due to the existing tail strobe light not meeting certification requirements regarding minimum intensity, thus the action specified rectifies this deficiency. While the directive itself applies nationally, its content and applicability are further defined through the associated Shorts Service Bulletin, and any subordinate instruments or updates would extend or refine the application of the directive.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically the AD/SD3-60/44 Strobe Lighting directive, mandate the incorporation of Modification No A8651 for SD3-60-200 variant aeroplanes. This modification involves the introduction of a new strobe light and power supply with associated hardware, as detailed in Shorts Service Bulletin SD360-33-25 Revision 1 dated July 1996 (Section 39 - 105). The requirement is clear: these changes must be implemented by all applicable aircraft to ensure compliance with safety standards. The directive references CAA(UK) AD 007-05-96, indicating alignment with UK Civil Aviation Authority's standards. The directive must be complied with before 31 March 1997, underscoring the urgency and importance of addressing the identified safety deficiencies. The obligations and requirements imposed by this directive are specific to the operators and maintainers of SD3-60-200 variant aeroplanes. Operators must ensure that their aircraft undergo the necessary modifications as outlined in the directive to meet the safety standards. This involves integrating the new strobe light and power supply, as per the referenced service bulletin, to rectify the issue of the existing tail strobe light not meeting minimum intensity requirements. The maintenance and operational staff must be adequately trained to perform these modifications and subsequent inspections to verify compliance. Operators need to maintain records of all modifications made to their aircraft, demonstrating adherence to the directive's stipulations. Failure to comply with the AD/SD3-60/44 directive can result in serious consequences. Non-compliance with the specified modifications and deadlines can lead to the aircraft being deemed unairworthy, resulting in grounding of the aircraft until the necessary changes are made. This not only impacts the operational readiness of the aircraft but also poses significant safety risks. Furthermore, there may be regulatory penalties imposed by the Civil Aviation Safety Authority, which could include fines or other administrative actions. The exact penalties are not detailed in the text, but they can be severe, reflecting the critical nature of maintaining safety standards in aviation.
