AD/G159/26 - Main Landing Gear Uplock Beam Bracket - Inspection

Overview

The Civil Aviation Orders, enacted in 1998 by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation operations across the nation. Specifically, Part 105 of the Civil Aviation Orders, which was introduced by the Civil Aviation Safety Authority, addresses the need for detailed and enforceable directives to maintain the airworthiness of aircraft. This legislative framework was established to fill the gap in providing a comprehensive regulatory structure for the oversight of civil aviation activities, ensuring they meet the highest safety standards. The policy objective underlying these Orders is to protect public safety and facilitate the safe, orderly and efficient development of civil aviation in Australia. One particular aspect of these Orders involves the issuance of Airworthiness Directives, as seen in the example provided for Gulfstream (Grumman) G.159 Series aeroplanes. This directive mandates specific inspections of the main landing gear uplock beam bracket for Gulfstream 1 and TC4C aeroplanes, as detailed in Grumman Customer Bulletin No. 272. The directive requires compliance within 100 hours of time in service after 29 August 1975, and subsequently at intervals not exceeding 100 hours. These directives are instrumental in maintaining the airworthiness of aircraft, thereby supporting the overarching policy objective of ensuring the safety of air travel.

Scope and Application

The Civil Aviation Orders, specifically Part 105 Schedule of Airworthiness Directives, applies to all Gulfstream 1 and TC4C aeroplanes, mandating compliance with the requirements outlined in the document titled Grumman Customer Bulletin No. 272. This legislation is pertinent to the aerospace industry, particularly to operators of the specified Gulfstream aeroplanes, and is concerned with the maintenance and inspection of the main landing gear uplock beam bracket. The applicability of this directive is clear, as it is designed to ensure the airworthiness of the specified aircraft models by enforcing regular inspections of the main landing gear uplock beam bracket. The geographic reach of these orders is national, as they are governed under the Commonwealth of Australia and are applicable across the entire country. This regulation does not include any stated exclusions or exemptions and applies uniformly to all relevant aircraft within the specified category. Further, the legislation extends its application through subordinate instruments, ensuring that the directives are adhered to with precision and regularity. The requirement for inspections within 100 hours of time in service after the directive's issuance on 29 August 1975, and subsequently at intervals not exceeding 100 hours, underscores the importance of maintaining the structural integrity of the specified aeroplanes. This ensures that all Gulfstream 1 and TC4C aeroplanes continue to meet the safety standards set forth by the Civil Aviation Safety Authority, thereby safeguarding the safety and reliability of air travel.

Key Provisions

The primary operative sections of the Civil Aviation Orders (CAO) Part 105, Schedule of Airworthiness Directives, specifically AD/G159/26, concern the inspection requirements for the main landing gear uplock beam bracket of the Gulfstream (Grumman) G.159 series aeroplanes. According to section 8/75, all Gulfstream 1 and TC4C aeroplanes are required to undergo inspections of their main landing gear uplock beam bracket. Compliance with these inspection requirements must be met within 100 hours of time in service after 29 August 1975, and subsequently at intervals not exceeding 100 hours of time in service. This directive is detailed in Grumman Customer Bulletin No. 272. The Act imposes specific obligations on the parties and entities it governs, ensuring that the safety and airworthiness of the Gulfstream G.159 series aeroplanes are maintained. Operators of these aeroplanes must ensure that the required inspections are conducted by qualified personnel in accordance with the specified intervals. The obligations extend to maintaining accurate records of these inspections to demonstrate compliance with the AD/G159/26 directive. Additionally, operators must ensure that any identified issues are addressed promptly and in accordance with the manufacturer's guidelines or other relevant safety directives. Failure to comply with the inspection requirements stipulated in AD/G159/26 can lead to serious consequences. The Act outlines various offences, penalties, and civil or criminal consequences for non-compliance. Specifically, under section 136 of the Civil Aviation Act 1988, non-compliance with airworthiness directives can result in penalties. For individuals, the penalty can include fines of up to $100,000, while for bodies corporate, the fines can be significantly higher, reaching up to $500,000. Furthermore, in cases of serious non-compliance, individuals may face imprisonment, and bodies corporate may be subject to additional penalties. These stringent measures underscore the importance of adhering to the prescribed inspection intervals and ensuring the safety of the aircraft and its passengers.
