AD/P68/27 - Fibre Glass Leading Edges

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, introduced by the Australian Government and administered by the Civil Aviation Safety Authority, was enacted to ensure the safety of civil aviation and the public. This legislative instrument aims to address specific safety concerns related to particular aircraft models, ensuring that they comply with airworthiness standards. One such directive, AD/P68/27, pertains to Partenavia P68 Series aeroplanes and mandates actions to address fibre glass leading edge issues. The directive was introduced to mitigate the risk of cracked and disconnected leading edge ribs, a safety concern reported by the manufacturer, and requires compliance within specified timeframes. The policy objective of this legislation is to ensure that all civil aircraft in Australia meet the required safety standards, particularly in relation to structural integrity and maintenance protocols. The Civil Aviation Safety Authority, through this directive, mandates that specific maintenance actions be undertaken on Partenavia P68 Series aeroplanes to prevent structural failure and ensure continued airworthiness. This regulation is crucial for maintaining the safety and reliability of civil aviation operations within Australia, reflecting a commitment to stringent safety oversight and adherence to manufacturer recommendations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the safety directives related to aircraft airworthiness in Australia, with the Civil Aviation Safety Authority being the overseeing body. Under this legislative instrument, Airworthiness Directive AD/P68/27 pertains to the Partenavia P68 series aeroplanes, including models P68, P68B, P68C, and P68C-TC, that have specific serial numbers as referenced in the Requirement Document. The directive mandates compliance with Partenavia Service Bulletin No. 67, requiring the inspection and, if necessary, the repair of fibre glass leading edges. This requirement must be fulfilled within 25 hours of time in service after 25 July 1985 and at each subsequent scheduled inspection for a Maintenance Release to be issued. The geographic reach of these regulations is national, applying uniformly across the Commonwealth of Australia, and it is enforced by the Civil Aviation Safety Authority. The regulations do not provide specific exclusions or exemptions, implying that all specified aircraft models must comply unless otherwise noted in subordinate instruments or specific circumstances.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate that all Partenavia P68 series aeroplanes, including models P68, P68B, P68C, and P68C-TC with serial numbers (S/Nos) as referenced in the Requirement Document, must comply with Airworthiness Directive AD/P68/27 (section 9/85 DM). This directive requires adherence to Partenavia Service Bulletin No. 67 concerning the fibre glass leading edges of these aircraft models. The directive applies to aircraft that have accumulated 25 hours of time in service following 25 July 1985, and must be re-evaluated at each subsequent scheduled inspection for the issuance of a Maintenance Release (section 9/85 DM). To comply with the regulations, operators and maintenance providers must inspect the fibre glass leading edges of the specified aircraft models and ensure they conform to the requirements outlined in Partenavia Service Bulletin No. 67. This involves a thorough examination of the leading edges to identify any cracked or disconnected ribs. The inspections must be completed within the specified timeframes to ensure the continued airworthiness of the aircraft. Failure to comply with these directives can result in serious safety implications and may lead to the grounding of the aircraft until the required inspections and repairs are conducted (section 9/85 DM). The Civil Aviation Regulations impose specific obligations on aircraft operators and maintenance providers to ensure the ongoing airworthiness of the aircraft. Operators must ensure that all inspections and required maintenance are performed in accordance with the stipulated timelines. Maintenance providers, on the other hand, are responsible for conducting the necessary inspections and repairs as per the Partenavia Service Bulletin No. 67. Both parties must maintain accurate records of all inspections and repairs carried out in compliance with the AD/P68/27 directive (section 9/85 DM). Failure to comply with the requirements of AD/P68/27 can result in severe civil and criminal penalties. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties, including fines and potential legal action. Additionally, operators or maintenance providers who fail to ensure compliance may face criminal charges, which can result in imprisonment. The specific penalties are determined by the severity of the non-compliance and the associated risks to aviation safety (section 9/85 DM).
