AD/BEECH 35/65 - Cabin Fresh Air Blower

Overview

The Civil Aviation Regulations 1998 (Cth), specifically under PART 39 - 105, addresses the safety of aircraft through the issuance of Airworthiness Directives. One such directive, AD/BEECH 35/65, pertains to the cabin fresh air blower of the Beechcraft 35 (Bonanza) Series Aeroplanes. This directive was introduced to address a problem involving the air blower housing attachment failures in certain models, which could potentially lead to significant safety hazards, such as the blower impinging on flight control cables. The directive aligns with the technical requirements of FAA AD 91-20-08 Amdt 39-8042, and requires compliance by Australian registered aircraft as specified, with a compliance deadline set for 12 December 1991. This directive is enacted by the Civil Aviation Safety Authority and aims to ensure the continued airworthiness and safety of the affected aircraft models.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 105, govern the application of airworthiness directives in Australia, ensuring that civil aviation safety standards are uniformly upheld across the nation. Specifically, AD/BEECH 35/65 pertains to the Beechcraft 35 (Bonanza) Series aeroplanes, with a focus on the cabin fresh air blower system for models V35B with specified serial numbers. This directive applies to aircraft registered in Australia and mandates compliance with the technical requirements outlined in FAA AD 91-20-08 Amdt 39-8042, referencing Beech SB 2380. The regulation aims to address reported issues of air blower housing attachment failures, which pose a risk of impingement on flight control cables, thereby enhancing flight safety. The effective date for compliance is set at 12 December 1991, extended by approximately one month from the original FAA requirement. This legislative instrument ensures that all relevant aircraft meet the stipulated safety standards within the Commonwealth of Australia.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39, concerning the Beechcraft 35 (Bonanza) Series Aeroplanes, include Section 105 which establishes the Airworthiness Directives (ADs) for specific aircraft types and models. In this instance, AD/BEECH 35/65 (paragraph 105) addresses the cabin fresh air blower for Model V35B aeroplanes with specified serial numbers (Section 105(1)). The requirement detailed in the directive mandates that the action be taken in accordance with the Technical Requirements of FAA AD 91-20-08 Amendment 39-8042 (Section 105(2)). The directive notes that compliance should follow the requirements specified in the referenced documents, with a revised effective date of 12 December 1991 for Australian registered aircraft (Section 105(3)). The Civil Aviation Regulations impose several obligations on the parties or entities governed by this legislation. Operators of the specified Beechcraft 35 (Bonanza) Series Aeroplanes must ensure that the cabin fresh air blower is maintained or modified in compliance with the FAA AD 91-20-08 Amendment 39-8042, as referenced in the Airworthiness Directive (Section 105(1)). This includes verifying that any attachment failures are rectified to prevent potential blower impingement on flight control cables (Section 105(2)). Operators must also adhere to the revised effective date of 12 December 1991 to ensure timely compliance for Australian registered aircraft (Section 105(3)). Additionally, operators should reference the Beech SB 2380 for further guidance on implementing the required actions. Failure to comply with the provisions of the Airworthiness Directive can result in significant consequences. Under the Civil Aviation Regulations 1998, non-compliance with ADs may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). This can include administrative penalties for operators who fail to address the specified airworthiness issues. In severe cases, CASA may take further action such as grounding the aircraft or imposing fines. The exact penalties and consequences for non-compliance are detailed in other sections of the Civil Aviation Regulations and can vary based on the severity and frequency of the breach.
