Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as a comprehensive regulatory framework governing aviation safety and operations within the country. Among its numerous provisions, Part 39, specifically Section 105, focuses on the authority and procedures of the Civil Aviation Safety Authority (CASA) in issuing airworthiness directives, ensuring that aircraft maintain a standard of airworthiness. This legislative instrument, F2006B04149, addresses the critical need for maintaining specific aircraft models, such as the Beechcraft 65 and 70 (Queen Air) series, to adhere to stringent safety standards. The directive AD/BEECH 65/53 Amendment 1, which mandates specific actions for the rudder and elevator trim tab systems, exemplifies the regulatory intent to prevent mechanical failures and ensure operational safety by implementing regular inspection and maintenance protocols. The overarching policy objective is to enhance aviation safety through continuous oversight and adherence to established maintenance procedures.
Scope and Application
The Civil Aviation Regulations 1998, specifically under PART 39 - 105, mandates Airworthiness Directives for certain Beechcraft 65 and 70 (Queen Air) series aeroplanes. This legislation applies to all models of Queen Air 65, A65 and A65-8200 with specified serial numbers, as well as models 65-80, 65-A80, 65-A80-8800, 65-B80, 65-88, and 70 with their respective serial numbers. The directive concerns the rudder and elevator trim tab systems and requires adherence to Beechcraft Service Instructions No. 0691-133 and -135 Rev. 2. Compliance is mandatory within 100 hours of time in service after 30 June 1980 and at intervals not exceeding 100 hours thereafter. The aim is to ensure that the inspection procedures and trim tab freeplay limitations specified in the service instructions are followed to prevent excessive wear in trim tab linkages or actuators. This regulation ensures the safety and airworthiness of the specified aircraft within Australia and its territories.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, addresses the airworthiness directives for certain Beechcraft aeroplanes. This legislative instrument mandates that owners or operators of Beechcraft 65 and 70 (Queen Air) series aeroplanes must adhere to specific maintenance requirements as outlined in the Beechcraft Service Instructions (SI) No. 0691-133, -135 Rev. 2. These directives apply to all models of Queen Air 65, including A65, A65-8200, 65-80, 65-A80, 65-A80-8800, 65-B80, and 70, within specified serial number ranges. The primary requirement is to perform actions in accordance with these service instructions to ensure that the rudder and elevator trim tab systems are maintained correctly.
The obligations under this legislation are clear and specific. Owners or operators must ensure that the inspection procedures and trim tab freeplay limitations, as outlined in the referenced service instructions, are followed diligently. This involves conducting inspections within 100 hours of time in service after 30 June 1980 and thereafter at intervals not exceeding 100 hours of time in service. These inspections are critical to identifying and rectifying any excessive wear in trim tab linkages or actuators, ensuring the continued airworthiness and safety of the aircraft.
Failure to comply with these airworthiness directives can lead to serious consequences. While the specific penalties for non-compliance are not detailed in the text, non-compliance with airworthiness directives can result in severe civil or criminal penalties under Australian aviation law. These can include fines, suspension or revocation of the aircraft’s certificate of airworthiness, and potential criminal charges if the non-compliance results in an accident or endangers flight safety. The severity of the penalties reflects the critical importance of adhering to these maintenance requirements to ensure the safety of all those involved in aviation activities.
