SCHEDULE OF AIRWORTHINESS DIRECTIVES
Beechcraft 56TC (Turbo Baron) Series Aeroplanes
AD/BEECH 56/19 Fuselage Bulkheads FS 257.6 and FS 271.92 4/79
Applicability: All models 56TC and A56TC with S/Nos. TG-2 to TG-94. 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 stabiliser attachments.
Overview
The Civil Aviation Regulations 1998, under Part 39 - 105, establish a framework for ensuring the airworthiness of aircraft operating in Australia, addressing issues related to safety and compliance with international standards. Specifically, AD/BEECH 56/19 was introduced to tackle the problem of potential structural integrity in Beechcraft 56TC (Turbo Baron) Series Aeroplanes, particularly concerning fuselage bulkheads FS 257.6 and FS 271.92. This directive was enacted by the Civil Aviation Safety Authority to ensure the safety of these aircraft, which are identified by serial numbers TG-2 to TG-94. The policy objective is to prevent the development of cracks in the specified bulkhead areas, which could compromise the aircraft's structural integrity and lead to catastrophic failures. The regulation mandates regular inspections and compliance with Beechcraft Service Instruction No. 0990 to maintain the airworthiness of the affected aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, governs the airworthiness directives for civil aircraft within Australia, including the Beechcraft 56TC (Turbo Baron) Series Aeroplanes. The legislation mandates that all models 56TC and A56TC with serial numbers ranging from TG-2 to TG-94 must comply with the specified airworthiness directive concerning fuselage bulkheads FS 257.6 and FS 271.92. The requirement necessitates an inspection and potential action in accordance with Beechcraft Service Instruction No. 0990, aimed at addressing the development of cracks in the specified bulkheads near the horizontal stabiliser attachments. The directive stipulates an initial inspection within 100 hours of time in service following 30 April 1979, with subsequent inspections required at intervals not exceeding 500 hours’ time in service or 1 year, whichever comes first. The regulations are applicable nationally within the Commonwealth of Australia and extend to all relevant aircraft, ensuring safety and airworthiness standards are maintained.
The scope of the regulation is comprehensive, applying to the specified models of Beechcraft 56TC and A56TC aeroplanes within the mentioned serial number range. The regulatory framework is designed to enforce compliance with safety directives to mitigate potential hazards arising from structural weaknesses. No specific exclusions, exemptions, or thresholds are mentioned in the directive, implying that all aircraft within the specified parameters must adhere to the inspection and action requirements. The directive's application is further extended through subordinate instruments such as service instructions and operational guidelines, ensuring that the safety measures are uniformly implemented across the relevant industry.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, Part 39 - 105, specifically AD/BEECH 56/19, concern the airworthiness of Beechcraft 56TC (Turbo Baron) Series Aeroplanes. This directive, issued on 4 July 1979, applies to all models 56TC and A56TC with serial numbers TG-2 to TG-94. The primary requirement (section 1) is to address potential cracks in the fuselage bulkheads FS 257.6 and FS 271.92, particularly in the areas of the horizontal stabiliser attachments, by following the instructions in Beechcraft Service Information (SI) No. 0990. This directive mandates an initial inspection within 100 hours of time in service after 30 April 1979, with subsequent inspections required at intervals not exceeding 500 hours of time in service or one year, whichever comes first (section 2).
The obligations imposed by this directive on the relevant parties include ensuring that inspections are conducted as specified. Operators of the affected aircraft must adhere to the inspection schedule and comply with the detailed procedures outlined in Beechcraft SI No. 0990 to maintain the structural integrity of the fuselage bulkheads. These inspections are critical to prevent the development of cracks, which could compromise the safety of the aircraft. Operators must also ensure that any identified issues are addressed promptly and in accordance with the manufacturer's guidelines to maintain the airworthiness of the aircraft.
Failure to comply with the requirements set out in AD/BEECH 56/19 can lead to significant consequences. The Civil Aviation Safety Authority (CASA) can take enforcement action against non-compliant operators. The penalties for breaches can be severe and may include substantial fines. In cases where non-compliance results in an aircraft being operated without meeting the specified airworthiness standards, the operator could face criminal charges, which may result in imprisonment. The exact penalties depend on the severity of the breach and the circumstances surrounding it, but they are designed to ensure that all operators take the necessary steps to maintain the safety of their aircraft.
