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 95/21 Fuselage Bulkheads FS 257.6 & FS 271.92 4/79
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 0990.
Compliance: Initially inspect within 100 hours’ time in service after 30 April 1979 and thereafter at intervals not exceeding 500 hours’ time in service or 1 year, whichever occurs first.
Background: Cracks may develop in the subject bulkheads in the areas of the horizontal stabilator attachments.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, provide a comprehensive framework for ensuring the safety of civil aviation in Australia. One particular legislative instrument, F2006B04293, was introduced to address a specific safety concern related to Beechcraft 95 (Travelair) Series Aeroplanes. This instrument targets fuselage bulkheads FS 257.6 and FS 271.92, aiming to mitigate the risk of cracks developing in these areas near the horizontal stabilator attachments, which could compromise the structural integrity of the aircraft. The policy objective is to mandate regular inspections to ensure ongoing airworthiness and passenger safety, thereby reducing the likelihood of in-flight failures. The requirement set forth in this legislative instrument ensures that all affected aircraft undergo initial inspection within 100 hours of service after 30 April 1979, followed by subsequent inspections at intervals not exceeding 500 hours of service or 1 year, whichever comes first.
This instrument is part of a broader effort by the Civil Aviation Safety Authority to implement Airworthiness Directives that maintain high safety standards within the aviation industry. By specifying detailed inspection protocols and timeframes, the legislation aims to proactively manage potential safety hazards and ensure that all relevant aircraft remain compliant with safety standards. The enactment of such measures underscores the commitment to safeguarding the public and maintaining the integrity of Australia's civil aviation sector.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, applies to the maintenance and inspection of Beechcraft 95 (Travelair) series aeroplanes, including all models 95, B95, B95A, D95A, and E95, with serial numbers ranging from TD-2 to TD-721. This regulation mandates compliance with the safety directive AD/BEECH 95/21, which necessitates the inspection of fuselage bulkheads FS 257.6 and FS 271.92 for potential cracks in the areas of the horizontal stabilator attachments. The inspection must initially be conducted within 100 hours of the aircraft’s time in service after 30 April 1979, followed by inspections at intervals not exceeding 500 hours’ time in service or once a year, whichever comes first. This directive is a crucial part of ensuring the airworthiness and safety of these aircraft within the Australian aviation sector.
Key Provisions
The primary sections of the Civil Aviation Regulations 1998, Part 39 - 105, as outlined in the Legislative Instrument AD/BEECH 95/21, pertain specifically to the Beechcraft 95 (Travelair) Series Aeroplanes, focusing on the fuselage bulkheads FS 257.6 and FS 271.92. These sections mandate actions to address potential structural integrity issues, particularly around the horizontal stabilator attachments. The regulation (section 1) identifies the affected aircraft models (95, B95, B95A, D95A, and E95) with serial numbers ranging from TD-2 to TD-721. The directive requires compliance with Beechcraft Service Instruction No 0990 (section 2), which outlines specific inspection and maintenance procedures to mitigate the risk of cracks in the designated fuselage bulkheads. The inspection must initially occur within 100 hours of time in service following 30 April 1979 and subsequently at intervals not exceeding 500 hours of time in service or 1 year, whichever comes first (section 3).
These provisions impose clear obligations on the owners, operators, and maintenance providers of the specified Beechcraft models. They must ensure that all inspections and required actions are carried out as per the stipulated intervals and in accordance with Beechcraft SI No 0990. This includes thorough examination of the fuselage bulkheads for any signs of cracks or other structural deficiencies. Proper documentation of all inspections and maintenance activities must be maintained to demonstrate compliance with the regulation (section 4). Failure to adhere to these inspection and maintenance schedules can compromise the airworthiness of the aircraft, leading to potential safety hazards.
Violation of these civil aviation safety directives can result in significant legal and financial consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance, and non-compliance can lead to penalties under the Civil Aviation Act 1988. In severe cases, CASA may impose fines, suspend or revoke airworthiness certificates, or take other regulatory actions against the non-compliant parties (section 5). The exact penalties can vary depending on the severity of the breach and the impact on aviation safety, but they are designed to ensure that all aircraft remain in a safe and airworthy condition at all times.
