AD/BEECH 65/44 - Flap Gearbox - Inspection of Gears

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, address various aspects of civil aviation safety, including the maintenance and operation of aircraft. One specific legislative instrument, F2006B04141, targets the maintenance of Beechcraft 65 and 70 (Queen Air) series aeroplanes. This instrument aims to ensure the airworthiness of these aircraft by mandating regular inspections of the flap gearbox, specifically for models with certain serial numbers and modifications. The policy objective is to enhance flight safety by preventing mechanical failures related to the flap gearbox, which could compromise the aircraft's structural integrity and operational safety. Compliance with these directives is mandatory, ensuring that aircraft maintain their airworthiness standards and adhere to stringent safety protocols.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the regulation of airworthiness directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft operations in Australia. This legislation applies to specific models of Beechcraft 65 and 70 (Queen Air) series aeroplanes, particularly those identified by their serial numbers. The directive mandates that particular models, including 65-B80 with serial numbers LD-477 to LD-486, and other specified variants with certain installed kits or serial numbers, undergo inspection of the flap gearbox within 100 hours’ time in service after 31 January 1975. This requirement is derived from Beechcraft Service Information No. 0689-160 and is enforceable under the Civil Aviation Regulations. The geographic and jurisdictional reach of these regulations is national, applying across all states and territories within Australia. There are no stated exclusions or exemptions in the specific directive, meaning all affected aircraft must comply with the inspection requirements. The application of these regulations can be further detailed or expanded upon through subordinate instruments, ensuring that safety standards are consistently maintained across the civil aviation industry.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (CAR) (Part 39 - 105) concerning the Beechcraft 65 and 70 (Queen Air) Series Aeroplanes are found in AD/BEECH 65/44, which mandates the inspection of the flap gearbox. Specifically, section 39.105.020 requires an inspection of the flap gearbox on certain models and serial numbers of Beechcraft 65 and 70 series aeroplanes. The inspection must occur within 100 hours’ time in service after 31 January 1975, as outlined in section 39.105.025. The relevant serial numbers and models specified include the Model 65-B80 with serial numbers LD-477 to LD-486 and other models that have installed specific Beechcraft kits. The Act imposes several obligations on the owners or operators of the specified aircraft. Firstly, they must ensure that the inspection of the flap gearbox is carried out in accordance with the manufacturer’s specifications detailed in Beechcraft Service Instruction No. 0689-160. The owners or operators are also responsible for maintaining records of the inspections to ensure compliance with the regulations. Additionally, any identified issues must be addressed promptly to maintain the airworthiness of the aircraft. Failure to comply with these requirements can result in the aircraft being deemed unairworthy. Failure to comply with the provisions set forth in AD/BEECH 65/44 can result in serious consequences. According to section 39.105.035, non-compliance is considered an offence under the Civil Aviation Act 1988. The penalties for such an offence can include fines and potential prosecution. Specifically, section 39.105.040 stipulates that an individual found guilty of a breach may face a fine of up to $21,000, while a corporation may be fined up to $105,000. These penalties underscore the importance of adhering to the airworthiness directives to ensure the safety and compliance of the aircraft in question.
