AD/SD3-30/33 - Elevator and Rudder Skin Flukes

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, include provisions aimed at ensuring the safety and airworthiness of aircraft operating within Australian airspace. One such provision, introduced to address issues related to the structural integrity of certain aircraft components, is found in Part 39 – 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives. Specifically, AD/SD3-30/33 pertains to the inspection of elevator and rudder skin flukes on all SD3-30 series aeroplanes. This directive was introduced to ensure that any substandard skin installation on empennage control surfaces, which could potentially compromise the aircraft’s safety, is identified and rectified. The objective of this legislation is to mandate compliance with Shorts Mandatory Service Bulletin SD330-55-19, referencing UK CAA AD 006-02-97, and to enforce inspection and rectification measures before a specified deadline to maintain the highest safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, governs the requirements for the airworthiness of aircraft within Australia. The AD/SD3-30/33 directive pertains to all SD3-30 series aeroplanes, mandating that the elevator and rudder skin flukes be inspected in accordance with the Shorts Mandatory Service Bulletin SD330-55-19. This directive ensures the continued airworthiness and safety of these aircraft by addressing potential issues with skin quality on empennage control surfaces. The directive is effective from 19 June 1997, and compliance is required unless the specified inspection has already been completed before 19 September 1997. This regulation applies to all operators of SD3-30 aircraft within Australia, ensuring adherence to safety standards established by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, outline specific requirements for maintaining the airworthiness of certain aircraft, including SD3-30 series aeroplanes. Section AD/SD3-30/33 addresses the inspection of elevator and rudder skin flukes, mandating that all SD3-30 aircraft undergo an inspection in accordance with Shorts Mandatory Service Bulletin SD330-55-19 (section 39-105). This directive references the UK Civil Aviation Authority's AD 006-02-97, indicating a cross-jurisdictional recognition of the need for these inspections. The directive is applicable to all SD3-30 aircraft, and compliance must be achieved before 19 September 1997, with the directive becoming effective on 19 June 1997 (section 39-105). This directive was issued due to the manufacturer's determination that some empennage control surfaces may have been installed with a substandard skin, which necessitates regular inspection to ensure ongoing airworthiness. The obligations imposed by this directive are specific and require aircraft operators to ensure that their SD3-30 series aeroplanes are inspected according to the prescribed service bulletin (section 39-105). This involves a thorough examination of the elevator and rudder skin flukes to identify and rectify any substandard skin installations. Operators must ensure that these inspections are conducted by qualified personnel who are familiar with the requirements outlined in Shorts Mandatory Service Bulletin SD330-55-19. Furthermore, operators are required to maintain accurate records of all inspections and any subsequent repairs or replacements of substandard skin components, as these records are essential for compliance verification and future reference (section 39-105). Failure to comply with the requirements of this airworthiness directive can lead to significant consequences. The Civil Aviation Regulations 1998 do not explicitly state the specific penalties for non-compliance with airworthiness directives in this context; however, non-compliance with airworthiness directives generally can result in severe penalties under the Civil Aviation Act 1988. These penalties may include fines and imprisonment for individuals, and fines for bodies corporate. Additionally, the operation of a non-compliant aircraft poses a serious safety risk, which can lead to the grounding of the aircraft by the Civil Aviation Safety Authority until the required inspections and repairs are completed. This not only incurs financial costs but also potentially disrupts the operator's schedule and reputation (section 39-105).
