Overview
The Civil Aviation Regulations 1998, specifically Part 39, were enacted to regulate the safety standards within Australia's civil aviation sector. Among these, AD/CESSNA310/15 Amendment 1, issued under the authority of the Civil Aviation Safety Authority, addresses the specific safety concerns related to the nose gear main drive tube assembly of Cessna 310 series aeroplanes. This legislation was introduced to mitigate the risk of accidents stemming from the degradation of the nose gear drive tube's bearing, as evidenced by incidents that had already occurred. The policy objective is to ensure the ongoing airworthiness of these aircraft by mandating regular inspections of the bearing, thus preventing potential failures that could compromise safety.
This legislative instrument, as amended, applies to all models of the Cessna 310 series that have accumulated over 1000 hours of service time and are equipped with the specified bearing part number 4NBC612ZP. The requirement is to inspect the bearing for any signs of movement between the outer bearing race and the eye end of the nose gear main drive tube, with compliance intervals set at no more than 200 hours of service time. This directive aims to enhance safety by ensuring that any potential issues are identified and rectified promptly, thereby protecting both the aircraft and its occupants.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 and Schedule of Airworthiness Directives, specifically target operators of Cessna 310 Series aeroplanes that have surpassed 1000 hours in service time and are equipped with a particular bearing, P/N 4NBC612ZP, fitted to the nose gear drive tube P/N 0842120-1. This legislation is applicable on a national level, encompassing all regions within Australia as it falls under the Commonwealth jurisdiction. The directive mandates the inspection of the specified bearing for any movement between the outer bearing race and the eye end of the nose gear main drive tube, with inspections to be conducted at intervals not exceeding 200 hours of service time. The original directive was issued on 5 September 1968, with this amendment and reissue becoming effective from 5 September 1991, highlighting a continuous commitment to aviation safety and the necessity for periodic checks to prevent potential accidents, as evidenced by past incidents that prompted these regulatory measures.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, address the Airworthiness Directives for the Cessna 310 Series Aeroplanes, including a notable amendment concerning the nose gear main drive tube assembly (AD/CESSNA310/15 Amdt 1). This directive applies to all models that have accrued more than 1000 hours of time in service and feature a bearing P/N 4NBC612ZP installed in the nose gear drive tube P/N 0842120-1. The key requirement under this directive is the inspection of the specified bearing for any movement between the outer bearing race and the eye end of the nose gear main drive tube (Section 39-105). The compliance with this inspection must occur at intervals not exceeding 200 hours of time in service (Section 39-105). This directive was originally issued on 5 September 1968, with the current reissue being effective from 5 September 1991.
Under this legislation, operators and owners of the affected Cessna 310 Series Aeroplanes have specific obligations. They must ensure that the inspections mandated by the Airworthiness Directive are performed strictly according to the stipulated intervals, not exceeding 200 hours of time in service. This requirement is critical to maintaining the safety standards set by the Civil Aviation Safety Authority. Failure to comply with these inspection intervals could lead to potential safety risks and non-compliance with the Civil Aviation Regulations.
Breach of the requirements set forth in the Airworthiness Directives can result in significant consequences. While the specific penalties are not detailed in the legislative instrument provided, non-compliance with Civil Aviation Regulations generally can result in enforcement actions by the Civil Aviation Safety Authority. These actions may include administrative penalties, fines, and in severe cases, grounding of the aircraft until compliance is achieved. The exact penalties can vary based on the severity and frequency of the breach but may also include civil or criminal charges under broader aviation safety legislation.
