COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Beechcraft 95 (Travelair) Series Aeroplanes
AD/BEECH 95/23 Control Surface Trim Tab Systems 6/80
Applicability: All models 95, B95, B95A, D95A and E95 with S/Nos. TD-2 to TD-721. Requirement: Action in accordance with Beechcraft SI No 0846-152, Rev 2.
Compliance: Within 100 hours’ time in service after 30 June 1980 and thereafter at intervals not exceeding 100 hours’ time in service.
Background: The inspection procedure defines maximum allowable control surface trim tab freeplay caused by accumulative wear in control linkages and actuators.
Overview
The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B04295, address the need for ensuring the airworthiness of certain aircraft models, specifically the Beechcraft 95 (Travelair) Series Aeroplanes. This legislation was enacted by the Australian Government to enhance aviation safety by implementing strict standards for maintaining the control surface trim tab systems of these aircraft. The objective is to prevent potential hazards caused by accumulative wear in control linkages and actuators, which could compromise the aircraft’s stability and handling. Compliance with these regulations is mandatory for all models 95, B95, B95A, D95A and E95 with specified serial numbers, requiring inspections and actions as per the instructions in Beechcraft SI No 0846-152, Rev 2, within 100 hours’ time in service following 30 June 1980 and subsequently at intervals not exceeding 100 hours’ time in service.
This legislative instrument was developed to fill a critical gap in ensuring that the specified Beechcraft models meet stringent safety standards, thereby safeguarding passengers, crew, and the general public. By mandating regular inspections and maintenance of the control surface trim tab systems, the legislation aims to mitigate the risks associated with operational wear and tear, contributing to overall aviation safety and regulatory compliance.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives for the Beechcraft 95 (Travelair) Series Aeroplanes, focusing on the control surface trim tab systems. This directive applies to all models 95, B95, B95A, D95A, and E95 with serial numbers ranging from TD-2 to TD-721. The primary requirement outlined in AD/BEECH 95/23 is compliance with Beechcraft Service Instruction No 0846-152, Revision 2, which specifies the necessary actions to maintain the airworthiness of these aircraft. The directive stipulates that these inspections and actions must be conducted within 100 hours of time in service following 30 June 1980 and subsequently at intervals not exceeding 100 hours of time in service. This regulation ensures that the control surface trim tab systems meet specified maximum allowable freeplay limits to prevent issues arising from wear in control linkages and actuators. The scope of this legislation is national, applying across the Commonwealth of Australia and overseen by the Civil Aviation Safety Authority. There are no stated exclusions, exemptions, or thresholds within this directive, and its application is further detailed through subordinate instruments as necessary.
Key Provisions
The key sections of the AD/BEECH 95/23 directive include the applicability (paragraph 1), which specifies that it applies to all models 95, B95, B95A, D95A, and E95 with serial numbers ranging from TD-2 to TD-721. The requirement (paragraph 2) is that action must be taken in accordance with Beechcraft Service Instruction No 0846-152, Revision 2. Compliance (paragraph 3) must occur within 100 hours of time in service after 30 June 1980 and subsequently at intervals not exceeding 100 hours of time in service.
The obligations imposed by this Act are primarily on the operators of the specified Beechcraft 95 series aeroplanes. They are required to ensure that the inspection and action stipulated in the Beechcraft Service Instruction No 0846-152, Revision 2, are carried out. This involves inspecting the control surface trim tab systems for any maximum allowable control surface trim tab freeplay caused by accumulative wear in the control linkages and actuators. Compliance with the directive is mandatory and must be achieved within the specified timeframes.
Failure to comply with the requirements set forth in AD/BEECH 95/23 may result in civil or criminal consequences. The exact nature of these consequences would depend on the severity of the breach and the circumstances of the non-compliance. However, the regulations do not explicitly state the maximum penalties for breach within the text provided. It is important for operators to adhere to the directive to avoid any potential legal repercussions or safety hazards.
