AD/BEECH 90/7 - Control Sub-Panel Shelf - Modification

Overview

The Civil Aviation Safety Authority, under the authority of the Civil Aviation Act 1988, has enacted the Civil Aviation Regulations 1998 to ensure the safe operation of aircraft within Australian airspace. Part 39 of these regulations, specifically the Airworthiness Directive AD/BEECH 90/7, addresses a critical safety issue concerning the control sub-panel shelf in Beechcraft 90 and 65-90 (King Air) series aeroplanes. This directive was introduced to mitigate the risk of the control sub-panel shelf detaching during flight, which could potentially lead to hazardous situations or loss of control. The policy objective of this regulation is to mandate modifications to the affected aircraft to ensure compliance and maintain the highest safety standards in civil aviation operations. Enacted by the Parliament of Australia, the Civil Aviation Regulations 1998 are designed to provide comprehensive guidelines and requirements for maintaining the airworthiness of aircraft. This particular directive targets specific models and serial numbers of the Beechcraft 90 and 65-90 series aeroplanes, requiring immediate action to modify the control sub-panel shelf as specified in Beechcraft SB 67-5. By enforcing these measures, the Civil Aviation Safety Authority aims to prevent incidents related to the detachment of the control sub-panel shelf, thereby protecting passengers, crew, and the public from potential dangers.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the application of Airworthiness Directives for civil aircraft within Australia. This particular legislative instrument pertains to the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes, targeting specific models and serial numbers. The directive mandates the modification of the control sub-panel shelf for models 65-90 and 65-A90 with serial numbers LJ-1 to LJ-194, LJ-203, LJ-205, LJ-220, and LJ-231. Compliance with this directive is required immediately, as specified in Beechcraft Service Bulletin 67-5. The regulation is applicable to aircraft operators and owners within the Commonwealth of Australia, ensuring safety standards are met across the national airspace. The scope of the legislation extends to all aircraft within the specified serial numbers operating in Australia, regardless of their use or ownership, ensuring that safety modifications are universally applied. The geographic reach is nationwide, with the directive overseen by the Civil Aviation Safety Authority (CASA). There are no stated exclusions or exemptions within the text provided, implying that all affected aircraft must comply without exception. The application of this directive may be further detailed or expanded through subordinate instruments, which might provide additional procedural or technical guidance necessary for compliance.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, provides a schedule of airworthiness directives (ADs) that are crucial for ensuring the safety of certain aircraft models, including the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. One such directive, AD/BEECH 90/7, concerns the modification of the control sub-panel shelf (section 11/67). This directive applies to Beechcraft models 65-90 and 65-A90 with specific serial numbers ranging from LJ-1 to LJ-194, LJ-203, LJ-205, LJ-220, and LJ-231. The directive mandates that the modification outlined in Beechcraft SB 67-5 be carried out immediately (section 11/67). Entities and parties governed by this directive, such as aircraft owners, operators, and maintenance service providers, have clear obligations. They must ensure that the specified modification to the control sub-panel shelf is completed without delay, adhering to the instructions provided in the referenced Beechcraft SB 67-5 document (section 11/67). This requirement underscores the importance of maintaining the structural integrity and operational safety of these aircraft. Failure to comply with this airworthiness directive can have serious legal consequences. Non-compliance may result in the aircraft being deemed unairworthy, leading to potential grounding of the aircraft until the necessary modifications are made. Furthermore, operators who fail to adhere to the ADs may face enforcement actions, including fines and sanctions imposed by the Civil Aviation Safety Authority (CASA). The specific penalties for non-compliance are not detailed in this particular directive, but they can be significant under the broader framework of the Civil Aviation Regulations 1998. The overarching aim is to ensure that all stakeholders prioritise safety and regulatory compliance to prevent accidents and maintain the highest standards of aviation safety.
