Overview

The Civil Aviation Regulations 1998, specifically Part 39, which includes AD/BEECH 65/56, was introduced to address safety concerns related to side windows of Beechcraft 65 and 70 (Queen Air) series aeroplanes. Enacted by the Australian Parliament, this regulation aims to ensure the safety of passengers and crew by mandating regular inspections and, where necessary, the replacement of side windows to prevent in-service failures. The policy objective is to mitigate the risk of window failure, which has been a documented issue both in Australia and internationally, by setting clear and regular inspection intervals to maintain airworthiness standards. The regulation applies to all Beechcraft 65-88 models with specific serial numbers, requiring initial inspections within 50 hours of service after 7 July 1981, followed by inspections at intervals not exceeding 300 hours of service or one year, whichever comes first. This proactive approach is intended to ensure that any potential issues are identified and rectified promptly, thus enhancing the overall safety of air travel. The requirement for inspections and subsequent actions is detailed in Beechcraft Service Instruction No. 0711-110, Revision 111, and references the Federal Aviation Administration’s Advisory Directive AD 81-12-01 Amendment 39-4126.

Scope and Application

The Civil Aviation Regulations 1998, as amended, encompass a comprehensive regulatory framework designed to ensure the safety and efficiency of civil aviation in Australia. Within this extensive body of regulations, Part 39 specifically addresses airworthiness directives, which are binding orders issued by the Civil Aviation Safety Authority (CASA) to ensure aircraft are maintained in a safe condition. The regulation in question, AD/BEECH 65/56, applies to all Beechcraft 65 and 70 (Queen Air) series aeroplanes with specific serial numbers LP-1 to LP-26, LP-28, and LP-30 to LP-47. The directive mandates a rigorous inspection schedule for the cabin, baggage, and pilot compartment side windows to prevent window failures, a known issue in similar aircraft models both domestically and internationally. Compliance with this directive is mandatory for all affected aircraft within the specified serial number range, and it must be adhered to under the oversight of CASA, ensuring that inspections are performed within 50 hours of time in service following the initial directive issuance and subsequently at intervals not exceeding 300 hours or one year, whichever comes first. This regulatory approach underscores the commitment to maintaining high safety standards across the Australian civil aviation sector.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, particularly the Airworthiness Directive AD/BEECH 65/56, focus on the inspection of side windows in Beechcraft 65 and 70 (Queen Air) Series Aeroplanes (section 1). This directive mandates inspections for all models 65-88 with serial numbers LP-1 to LP-26, LP-28, and LP-30 to LP-47. The inspection is a response to documented failures of side windows in similar aircraft both in Australia and internationally, which could potentially compromise the structural integrity and safety of the aeroplanes (section 2). Under this Act, the operators of the specified Beechcraft models are obligated to conduct an initial inspection within 50 hours of the aeroplanes being in service after 7 July 1981. Following this initial inspection, further inspections are required at intervals not exceeding 300 hours of service or annually, whichever comes first, until the windows are replaced as per Beechcraft Service Instruction No. 0711-110, Revision 111 (section 3). This ongoing requirement ensures that the windows are regularly assessed for any signs of wear, damage, or deterioration that could lead to in-flight failures. Failure to comply with the inspection requirements set forth in the Airworthiness Directive can result in significant legal and operational repercussions. The Civil Aviation Safety Authority (CASA) may take enforcement actions against non-compliant operators. These actions can include fines, suspension of airworthiness certificates, or other regulatory penalties. The potential penalties are designed to ensure that all operators adhere strictly to the safety standards, thereby maintaining the high safety standards of Australian civil aviation (section 4). The maximum penalties can vary depending on the severity and frequency of non-compliance but are intended to ensure that operators take the safety directives seriously.
