AD/BEECH 23/3 - Stabilator Hinge Assembly

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation in Australia. Among the various amendments and directives, Part 39 specifically addresses airworthiness directives to maintain the safety of aircraft. One such directive, AD/BEECH 23/3, targets Beechcraft 19, 23, and 24 Series aeroplanes, particularly focusing on stabilator hinge assemblies to prevent structural issues that could compromise flight safety. This legislative instrument was introduced to address potential cracking in the stabilator hinge attachment of Model 23 aeroplanes, requiring modifications approved by the Secretary to ensure compliance before a specified deadline, as outlined in Beechcraft Service Instruction No. 64-22. The policy objective is to mitigate risks associated with structural failures, thereby enhancing the overall safety of civil aviation operations.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives under the Civil Aviation Regulations 1998, specifically AD/BEECH 23/3, applies to Beechcraft Model 23 aeroplanes. This legislation mandates modifications to the stabilator hinge assembly to prevent potential structural failures that could result from cracking of the adjacent fuselage skin, doubler, and frame. The directive requires adherence to the modification scheme approved by the Secretary and outlines compliance requirements that must be fulfilled before 1 September 1971. The directive's jurisdiction extends nationally as it is a regulation under Commonwealth legislation, thereby affecting all entities operating Beechcraft Model 23 aeroplanes within Australia. There are no stated exclusions or exemptions in this directive, and compliance is mandatory for all relevant aircraft within the specified timeframe. The scope of this legislation is further extended or clarified through subordinate instruments, ensuring comprehensive oversight and enforcement of the stipulated modifications.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998, specifically Part 39 - 105, concern Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/BEECH 23/3, addresses the stabilator hinge assembly for Beechcraft 19, 23, and 24 series aeroplanes, with a particular focus on the Model 23 aeroplane (section 4/64). This directive mandates modifications to prevent cracking of the stabilator hinge's attachment to the fuselage, including the adjacent fuselage skin, doubler, and frame. The changes must adhere to a scheme approved by the Secretary, as outlined in Beechcraft Service Instruction No. 64-22. Compliance with these requirements is mandatory, with the directive specifying that modifications must be completed before 1 September 1971. The obligations under this directive require operators and owners of Model 23 Beechcraft aeroplanes to ensure that the stabilator hinge assembly is modified according to the approved scheme. This involves not only physical modifications but also ensuring that any documentation and approvals are in order and up to date. Operators must maintain records demonstrating compliance with the directive and ensure that any work carried out is performed by appropriately qualified personnel. Additionally, operators must ensure that the aeroplane remains airworthy throughout the modification process, adhering to all relevant safety standards and practices. Failure to comply with AD/BEECH 23/3 can result in significant consequences. The Act provides for both civil and criminal penalties for non-compliance. Civil penalties may include fines and other monetary penalties, as stipulated by the Civil Aviation Act 1988. For criminal offences, the maximum penalties can be severe, including fines of up to $210,000 for individuals and $1,050,000 for corporations, as well as potential imprisonment terms. These penalties underscore the importance of strict adherence to the directive to avoid legal repercussions and ensure the continued safety and airworthiness of the aircraft in question.
