AD/P68/16 Amdt 1 - Engine and Engine Mount Attach Bolts

Overview

The Civil Aviation Regulations 1998, amended by F2006B05343, pertain to the enforcement of airworthiness directives within Australia, specifically addressing safety concerns associated with certain Partenavia P68 series aeroplanes. Enacted by the Australian Government, this legislative instrument is designed to ensure that all relevant aircraft meet the necessary safety standards to operate. The amendment introduces a more stringent inspection regime for the bolts connecting the engine to the engine mount and the engine mount to the aircraft structure, aiming to prevent potential failures that could compromise flight safety. The policy objective is to enhance the safety of civil aviation by ensuring that aircraft components are regularly inspected and maintained according to the most current and stringent standards set by the manufacturer. This amendment was introduced by the Civil Aviation Safety Authority under the authority of the Civil Aviation Act 1988, reflecting a commitment to maintaining high safety standards in the aviation industry. The regulation requires specific inspections and torque checks on the bolts of the mentioned aircraft models, ensuring they are conducted at each engine installation and at intervals not exceeding 100 hours of service time. The revision was made to incorporate updated manufacturer criteria, thereby addressing potential safety gaps that could arise from outdated inspection practices.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, applies to all aircraft types listed under the directive, in this case, the Partenavia P68 series aeroplanes, including variants such as the P68, P68B, P68R, P68C, P68 Obs, P68-TC, and P68-TC Obs. This regulation mandates that the engine and engine mount attach bolts be inspected and checked for correct torque loading, as per Partenavia S.B. 76 Rev 1. Compliance with this directive is required at each engine installation and at intervals not exceeding 100 hours of time in service. The geographic reach of this legislation is national, impacting all operators of the specified aircraft within Australia. The directive does not specify exclusions or exemptions, indicating that all relevant aircraft must comply with the stipulated inspection and maintenance requirements. Additionally, the application of this directive may be further detailed or extended through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate the requirements for maintaining the airworthiness of Partenavia P68 Series Aeroplanes. Section AD/P68/16 Amendment 1 focuses on the inspection and maintenance of the engine and engine mount attach bolts for these aircraft models. The key requirements are outlined in the regulation, which necessitate inspections of the bolts attaching the engine to the engine mount and those attaching the engine mount to the aircraft structure, following the criteria set forth in Partenavia S.B. 76 Revision 1 (section 1). Additionally, it requires verification that the nuts associated with these bolts are torqued to the correct specifications (section 2). Compliance with these provisions is mandatory and must occur at each engine installation, and subsequently, at intervals not exceeding 100 hours of time in service (section Compliance 1 and 2). The rationale behind these regulations is to ensure that the structural integrity of the engine and engine mount is maintained, thereby enhancing safety during flight operations. The applicability of these requirements extends to all variants of the Partenavia P68 Series, including P68, P68B, P68R, P68C, P68 Obs, P68-TC, and P68-TC Obs. Entities and individuals governed by these regulations are required to adhere strictly to the inspection and maintenance protocols stipulated. This involves not only the initial inspection at engine installation but also ongoing checks at regular intervals to ensure the bolts and nuts remain within the specified parameters. Failure to comply with these mandates could lead to serious safety implications, as the structural integrity of the engine and engine mount is critical to the overall airworthiness of the aircraft. In the event of non-compliance, there are potential civil and criminal consequences. While the specific penalties are not detailed in the text provided, non-compliance with airworthiness directives can typically lead to significant regulatory action. This may include fines, suspension or revocation of the aircraft's certificate of airworthiness, and potential criminal charges against responsible parties. Such actions are designed to enforce adherence to safety standards and to deter negligence that could compromise flight safety.
