AD/BEECH 35/29 - Engine Mount Bolt Nuts

Overview

The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B03828, specifically address the issue of airworthiness directives to ensure the safety and compliance of aircraft operations within Australia. Enacted by the Australian Government, this legislation was introduced to address the critical need for maintaining stringent safety standards in civil aviation. The policy objective of this directive is to mandate compliance with specific safety instructions issued by the Civil Aviation Safety Authority (CASA) to rectify known safety deficiencies in the Beechcraft 35 (Bonanza) Series Aeroplanes. This particular legislative instrument focuses on the requirement for engine mount bolt nuts, applicable to all models with serial numbers D-8837 and subsequent, mandating action in accordance with Beechcraft Service Information No. 0396-241, with a compliance timeline set within 25 hours of time in service after 21 August 1970.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the safety directives concerning the airworthiness of certain aircraft, with this particular legislative instrument focusing on Beechcraft 35 (Bonanza) Series Aeroplanes. This regulation applies to all models of the Beechcraft 35 series with serial numbers D-8837 and subsequent. The directive mandates that action be taken in accordance with Beechcraft Service Information No. 0396-241, specifically addressing the engine mount bolt nuts, to ensure compliance with safety standards. This requirement must be fulfilled within 25 hours of time in service after 21 August 1970, establishing a clear timeline for the necessary maintenance actions. The regulation’s scope is limited to the specified aircraft models and does not extend to other aircraft types or models outside the defined serial numbers. The Civil Aviation Safety Authority oversees the implementation and compliance of these directives to maintain airworthiness standards.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) establish specific requirements for the airworthiness of aircraft in Australian airspace, with Part 39 focusing on airworthiness directives (ADs). One such directive, AD/BEECH 35/29, pertains to the Beechcraft 35 (Bonanza) Series Aeroplanes, specifically regarding engine mount bolt nuts (Section 105). This directive applies to all models with serial numbers D-8837 and subsequent. The primary requirement under this directive is to take action in accordance with Beechcraft Service Information (SI) No. 0396-241. This action must be completed within 25 hours of time in service following 21 August 1970, ensuring that the aircraft meets the specified safety standards. The obligations imposed by this AD on the operators of Beechcraft 35 (Bonanza) Series Aeroplanes include ensuring that the specified maintenance action is carried out without delay. Operators must verify that the engine mount bolt nuts are addressed in line with the instructions provided by Beechcraft SI No. 0396-241. This involves detailed inspection and, where necessary, repair or replacement of the bolts to ensure they meet the safety requirements set forth by the Civil Aviation Safety Authority (CASA). Compliance with these directives is mandatory, and failure to adhere to the specified timeframes and procedures could result in the aircraft being deemed unairworthy. Failure to comply with AD/BEECH 35/29 may result in severe consequences, including potential enforcement actions by CASA. Non-compliance with airworthiness directives can lead to penalties, including fines and other sanctions as stipulated by the Civil Aviation Act 1988 (Cth). In more severe cases, CASA may take action to suspend or revoke the aircraft's certificate of airworthiness, which could result in the aircraft being grounded until the required maintenance is performed. The specific penalties and consequences for non-compliance are governed by the broader regulatory framework, but they underscore the importance of adhering to the directives to ensure the safety of flight operations.
