AD/SD3-30/32 - Inner Flap Sub-Assembly Lever Bracket

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, introduced the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives to address safety concerns related to civil aviation. Specifically, AD/SD3-30/32 targets the inner flap sub-assembly lever bracket for all SD3-30 series aeroplanes, responding to manufacturer reports of corrosion and cracking in this component. The directive mandates inspections in accordance with the Shorts Mandatory Service Bulletin SD3-27-36, with an initial inspection required before 27 July 1997 and subsequent inspections as specified in the requirement document for ongoing safety. This legislative instrument, enacted by the Commonwealth of Australia, aims to ensure the continued airworthiness and safety of the specified aircraft by enforcing regular inspections and maintenance protocols.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39, specifically address the safety and airworthiness of aircraft through various directives, including AD/SD3-30/32 concerning the inner flap sub-assembly lever bracket of SD3-30 series aeroplanes. This directive applies to all SD3-30 aircraft, mandating that inspections be conducted in accordance with the manufacturer's Mandatory Service Bulletin SD3-27-36. The directive requires an initial inspection before 27 July 1997, with subsequent inspections to be performed as specified in the requirement document, ensuring ongoing compliance with airworthiness standards. This regulatory framework is enforced by the Civil Aviation Safety Authority and applies nationwide within Australia, ensuring that all SD3-30 aircraft meet the specified safety requirements to maintain airworthiness. The directive is clear in its applicability and compliance requirements, with no stated exclusions or thresholds in the provided text.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the authority of the Civil Aviation Safety Authority, issue a Schedule of Airworthiness Directives (AD) that govern the maintenance and safety standards of aircraft. One such directive, AD/SD3-30/32, pertains to the inner flap sub-assembly lever bracket of all SD3-30 series aeroplanes (Section 1). This directive requires an inspection of these components in accordance with the manufacturer’s Mandatory Service Bulletin SD3-27-36 (Section 2). The initial inspection must be conducted before 27 July 1997, with subsequent inspections following the intervals outlined in the Requirement Document (Section 3). The directive came into effect on 24 April 1997 (Section 4), prompted by the manufacturer's reports of corrosion and cracking on these brackets. The obligations imposed by this directive are clear and specific. Operators of SD3-30 aircraft are required to ensure that all inner flap sub-assembly lever brackets are inspected according to the manufacturer's guidelines. This involves adhering to the timeframes set out in the directive and the Requirement Document, which detail the periodicity of these inspections. Failure to comply with these inspection requirements could potentially compromise the airworthiness of the aircraft, leading to safety risks. Breaching the requirements of this Airworthiness Directive can result in serious consequences. Although the Civil Aviation Regulations do not specify the exact penalties for non-compliance with this particular directive, general penalties for failing to comply with airworthiness directives can include fines, enforcement actions, and potential grounding of the aircraft. In more severe cases, criminal charges could be brought against individuals or companies responsible for the non-compliance, leading to substantial financial penalties and imprisonment. The overarching aim of these provisions is to ensure that all SD3-30 series aeroplanes maintain their airworthiness and safety standards, thereby protecting both the crew and passengers on board.
