Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which includes AD/SD3-60/6 related to oil cooler left air intake scoop modifications for certain model SD3-60 aeroplanes. This directive was introduced to address a problem identified by the manufacturer, where high oil temperature readings were recorded during operations in severe icing conditions. The Civil Aviation Safety Authority, acting under the authority of the Australian Parliament, established this directive to ensure the continued airworthiness and safety of the specified aircraft models. The policy objective is to mitigate the risk of engine failure due to elevated oil temperatures in adverse weather conditions, thereby maintaining the integrity of flight operations and protecting passenger safety.
The directive applies to all model SD3-60 aeroplanes with serial numbers SH 3601 to SH 3629, SH 3631, and SH 3632, mandating that modifications to the oil cooler left air intake scoop be completed before 30 November 1984. Compliance with this directive is essential to ensure that the aircraft can safely operate in environments with severe icing conditions, thereby preventing potential engine overheating and associated risks. The legislation underscores the importance of proactive measures in aviation safety, reflecting a commitment to uphold stringent safety standards across the industry.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, focusing on the safety and operational standards of aircraft within Australia. This particular regulation, AD/SD3-60/6, applies to all Short SD3-60 model aeroplanes with serial numbers SH 3601 to SH 3629, SH 3631, and SH 3632. The directive mandates modifications to the oil cooler left air intake scoop to mitigate risks associated with high oil temperature readings in severe icing conditions. This requirement is designed to ensure the continued airworthiness of these aircraft, thereby protecting the safety of passengers, crew, and the general public. The regulation operates under the national jurisdiction of the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority, with compliance mandated by the specified deadline of 30 November 1984. This directive is supported by the Shorts SB SD360-71-05 document, which provides detailed instructions on the required modifications.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives. One such directive, AD/SD3-60/6, pertains to the oil cooler left air intake scoop modification for Short SD3-60 Series Aeroplanes. According to section 6/84, this directive applies to all model SD3-60 aircraft with serial numbers SH 3601 to SH 3629, SH 3631, and SH 3632. The directive requires these aircraft to undergo modifications as detailed in Shorts SB SD360-71-05 and mandates that the modifications must be completed before 30 November 1984.
The primary requirement of this directive is the modification of the oil cooler left air intake scoop to address high oil temperature readings that have been recorded during operation in severe icing conditions. This directive is critical for ensuring the continued airworthiness and safety of the affected aircraft. The modifications are intended to mitigate the risk of overheating, which could lead to engine failure or other critical failures during flight.
Compliance with AD/SD3-60/6 is mandatory for the specified aircraft. The directive imposes obligations on aircraft owners, operators, and maintenance personnel to ensure that the required modifications are made by the specified deadline. This includes verifying that the aircraft fall within the serial numbers identified, accessing and following the guidance provided in Shorts SB SD360-71-05, and ensuring that all modifications are completed and documented properly. Failure to comply with this directive can result in serious safety implications and potential regulatory action.
In terms of consequences for non-compliance, the Civil Aviation Regulations 1998 outline various penalties and enforcement actions. Although specific penalties for non-compliance with AD/SD3-60/6 are not detailed in the provided excerpt, general regulations indicate that non-compliance with airworthiness directives can result in significant civil penalties, including fines. Additionally, CASA has the authority to take enforcement actions such as grounding non-compliant aircraft, which can have severe operational and financial implications for the operators. In the most severe cases, non-compliance can lead to criminal charges, resulting in imprisonment, particularly if the non-compliance leads to an aviation accident or incident.
