AD/BEECH 60/8 - Engine Mount Bolt Nuts

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were designed to comprehensively regulate all aspects of civil aviation within the country. One particular legislative instrument, F2006B04112, introduced under the authority of the Civil Aviation Act 1988, addresses specific safety directives for certain aircraft models. This legislative instrument, AD/BEECH 60/8, was introduced to address the problem of ensuring the airworthiness of Beechcraft 60 (Duke) Series Aeroplanes by specifying requirements for the engine mount bolt nuts. The policy objective behind this directive is to maintain high safety standards within civil aviation by ensuring that critical components of aircraft are regularly inspected and maintained according to stringent specifications. The Civil Aviation Safety Authority, as the enforcing body, mandates compliance with this directive to mitigate risks associated with the engine mount bolt nuts, ensuring the safety and reliability of the aircraft. The requirement is that all models with serial numbers P-5 and subsequent must adhere to the actions outlined in Beechcraft Service Instruction No. 0396-241, with compliance expected within 25 hours of time in service after 21 August 1971.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 105, specifically address the safety and airworthiness of aircraft through the issuance of Airworthiness Directives (ADs). This particular legislation, AD/BEECH 60/8, pertains to all Beechcraft 60 (Duke) Series aeroplanes with serial numbers P-5 and subsequent. It mandates compliance with Beechcraft Service Instruction No. 0396-241, which outlines the required action concerning the engine mount bolt nuts. The directive is applicable to the relevant aircraft models and requires compliance within 25 hours of time in service after the issuance date of 21 August 1971. This regulation is part of a broader framework overseen by the Civil Aviation Safety Authority, ensuring that the specified aircraft meet necessary safety standards to maintain airworthiness. The regulation is enforced within the Commonwealth of Australia and applies to the entities or individuals operating these aircraft, ensuring uniformity and safety across the national airspace.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Beechcraft 60 (Duke) Series Aeroplanes, detail requirements for maintaining the airworthiness of these aircraft models. Section 39-105 (AD/BEECH 60/8) mandates that all models with serial numbers (S/Nos.) P-5 and subsequent must adhere to the action specified in Beechcraft Service Instruction No. 0396-241 regarding the engine mount bolt nuts. This action must be completed within 25 hours’ time in service after 21 August 1971. This means that owners and operators of these aircraft must ensure that the specified maintenance work on the engine mount bolt nuts is carried out as per the detailed instructions provided by Beechcraft. The obligations imposed by this Act on the parties or entities it governs include a strict timeline for compliance, which is critical for ensuring the safety and airworthiness of the aircraft. Operators and owners of the affected Beechcraft 60 (Duke) Series aeroplanes must verify that the engine mount bolt nuts are addressed within the specified timeframe to remain compliant with the regulations. This involves following the detailed maintenance instructions provided by Beechcraft to ensure that the necessary actions are carried out correctly and effectively. Failure to comply with these obligations can result in the aircraft being deemed unairworthy, which could lead to operational restrictions and potential grounding of the aircraft. The consequences for non-compliance with the provisions outlined in Section 39-105 (AD/BEECH 60/8) can be significant. The Civil Aviation Safety Authority (CASA) can impose both civil and criminal penalties for failure to adhere to the mandated airworthiness directives. Civil penalties may include fines and the potential for enforcement actions such as grounding of the aircraft until compliance is achieved. In more severe cases, where non-compliance is found to have led to unsafe conditions or accidents, criminal charges may be pursued against the responsible parties. The exact penalties are not specified in the provided text, but they can be substantial, reflecting the importance of maintaining airworthiness standards to ensure the safety of all involved in aviation activities.
