AD/BEECH 65/7 Amdt 1 - Landing Gear Chain and Torque Shaft - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form the backbone of civil aviation regulation within the country, providing the necessary framework for maintaining safety standards. This legislation is part of a broader set of regulations overseen by the Civil Aviation Safety Authority (CASA) and aims to ensure that all aircraft operating within Australian airspace meet stringent safety requirements. One specific legislative instrument within this framework is F2006B04164, which pertains to Airworthiness Directives for certain aircraft models, including the Beechcraft 65 and 70 (Queen Air) series aeroplanes. This directive, among others, was introduced to address specific safety concerns identified in the operation of these aircraft models. The policy objective behind such directives is to mandate regular inspections and maintenance actions to prevent potential mechanical failures, thereby enhancing overall aviation safety. The specific Airworthiness Directive AD/BEECH 65/7 Amendment 1 targets the landing gear chain and torque shaft of Beechcraft 65 and 70 series aeroplanes. It requires inspections to be conducted within 25 hours of time in service after a specified date, in this case, 15 March 1967. The directive applies to particular serial numbers of the models A65 and 65-B80, ensuring that only those aeroplanes identified are subject to these inspection requirements. This targeted approach is designed to mitigate risks associated with known mechanical issues, ensuring that these aircraft remain airworthy and safe for operation.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically Part 39 - 105, issues Airworthiness Directives (AD) to ensure the safe operation of aircraft within Australian airspace. One such directive, AD/BEECH 65/7 Amendment 1, pertains to the inspection of the landing gear chain and torque shaft on Beechcraft 65 and 70 (Queen Air) series aeroplanes. This AD applies to specific serial numbers of the Model A65, ranging from LC-240 to LC-249, and the Model 65-B80, with serial numbers between LD-270 and LD-330. Compliance with this directive is mandatory, requiring that the specified inspection be conducted within 25 hours’ time in service following 15 March 1967, in accordance with the guidance provided in Beechcraft Service Bulletin 67-1. The regulation extends to all aircraft fitting the specified models and serial numbers operating in Australian airspace, with no exclusions or exemptions mentioned in the directive. The scope of the AD is defined strictly to the identified aircraft models and serial numbers, and it does not extend to other types of aircraft unless similarly specified in other ADs.

Key Provisions

The key operative sections of the AD/BEECH 65/7 Amendment 1 mandate specific actions regarding the inspection of landing gear chains and torque shafts for certain Beechcraft 65 and 70 (Queen Air) series aeroplanes. Section (1) identifies the applicable models and serial numbers that must comply with these requirements, namely Model A65 with serial numbers LC-240 to LC-249 and Model 65-B80 with serial numbers LD-270 to LD-330. Section (2) specifies the document, Beechcraft SB 67-1, which provides the detailed instructions for the required inspection. Section (3) sets the compliance deadline, stipulating that the inspection must be completed within 25 hours of time in service after 15 March 1967. The obligations imposed by this legislation are clear and specific. Owners and operators of the affected Beechcraft aeroplanes must ensure that the inspection of the landing gear chains and torque shafts is conducted according to the instructions outlined in Beechcraft SB 67-1. This requirement is binding and must be fulfilled within the specified timeframe to maintain compliance with civil aviation safety standards. Failure to adhere to these requirements could result in the aircraft being deemed unairworthy, which would prevent it from operating legally. Breaches of these regulations can have serious consequences. While the specific penalties are not detailed in this excerpt, generally, violations of civil aviation safety directives can lead to significant civil and criminal penalties. These may include fines, suspension or revocation of aircraft certificates, and potential criminal charges for those responsible for the non-compliance. The severity of the penalties reflects the importance of adhering to safety directives to ensure the continued safety of air travel.
