Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, aim to ensure the safety of civil aviation operations within the country. This legislative instrument is part of a broader framework designed to address various aviation safety issues, including the need to manage and mitigate risks associated with specific aircraft models. The particular regulation in focus pertains to Beechcraft 55, 58 and 95-55 (Baron) series aeroplanes, specifically addressing elevator control push rod corrosion issues. The regulation mandates actions in accordance with Beechcraft Service Information No. 1019 and requires compliance within 100 hours’ time in service after 31 May 1980, reflecting a policy objective to enhance air safety by addressing known mechanical vulnerabilities in these aircraft models.
This regulation was introduced to address the identified problem of corrosion in the elevator pushrods of certain Beechcraft models, a safety concern that was previously observed in other models with similar pushrod designs. By mandating specific maintenance actions and timeframes, the regulation seeks to proactively prevent potential in-flight failures and ensure the continued airworthiness of these aircraft, thereby protecting both passengers and crew.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of airworthiness directives to ensure the safety of aviation operations. This legislative instrument targets the Beechcraft 55, 58, and 95-55 (Baron) series aeroplanes by requiring compliance with AD/BEECH 55/58 concerning the elevator control push rods. The directive applies to specific serial number ranges across various model types, such as 95-55, 95-A55, 95-B55, 95-B55A, 95-C55, 95-C55A, D55, D55A, E55, E55A, 58, 58A, 58P, 58PA, 58TC, and 58TCA, all of which must adhere to the action specified in Beechcraft Service Information No. 1019. Compliance must be achieved within 100 hours of the aeroplane's time in service after 31 May 1980, reflecting the urgency and importance of addressing potential corrosion issues identified in similar models. This regulation ensures the maintenance of safety standards across the specified aircraft, thereby protecting the integrity of civil aviation operations within Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Airworthiness Directives applicable to various aircraft models, including the Beechcraft 55, 58 and 95-55 (Baron) series aeroplanes. Section 3/80 focuses on the elevator control pushrods of these aircraft models, establishing requirements and compliance timelines for their maintenance. This directive is critical for ensuring the structural integrity and safe operation of these aircraft by addressing potential corrosion issues in the elevator pushrods, which have been observed in other similar models.
In terms of applicability, Section 3/80 specifies a range of serial numbers for each model variant of the Beechcraft 55, 58 and 95-55 series aeroplanes. Owners and operators of these aircraft must ensure that the elevator control pushrods are examined and maintained according to the specified requirements. The directive mandates compliance within 100 hours of time in service after 31 May 1980.
To comply with the directive, aircraft owners and operators must follow the instructions provided in Beechcraft Service Information (SI) No. 1019. This includes conducting a thorough inspection of the elevator control pushrods and taking corrective action as necessary. The directive is designed to mitigate the risk of structural failure due to corrosion, ensuring the continued airworthiness of the affected aircraft.
Failure to comply with the requirements outlined in Section 3/80 of the Civil Aviation Regulations 1998 could result in serious safety implications. The Civil Aviation Safety Authority (CASA) can impose various penalties and consequences for non-compliance. If an aircraft is found to be operating without the required maintenance on the elevator control pushrods, the operator could face enforcement actions, including fines, suspension or revocation of the aircraft’s Certificate of Airworthiness. These measures are in place to ensure that all aircraft meet the necessary safety standards and to protect the public from potential hazards.
