Overview

The Civil Aviation Regulations 1998, specifically Part 39, addresses various safety concerns and requirements within the aviation sector in Australia. This legislation was enacted to ensure the safety and airworthiness of aircraft and aeronautical products by providing comprehensive guidelines and directives. One such directive is the Airworthiness Directive AD/P68/50, issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 by a delegate of the Civil Aviation Safety Authority (CASA). This directive was introduced to address safety issues related to the installation and structural integrity of certain Partenavia P68 Series Aeroplanes. Specifically, the directive aims to correct unsafe conditions identified in the forward stabilator connecting rod/control column bolt, the installation of a missing nut, and interference between the forward control lever assembly and the aircraft structure. The policy objective behind this AD is to ensure that all affected aircraft are inspected and maintained according to the specified requirements to prevent potential safety hazards during flight.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) to ensure aircraft safety. This particular Airworthiness Directive (AD) pertains to Partenavia P68 Series Aeroplanes, more specifically, all Model P68 Observer 2 aircraft with serial numbers 401 through 413, and Model P68C aircraft with serial number 402. The directive mandates an inspection of these aircraft to rectify the unsafe condition identified, namely an incorrectly installed forward stabilator connecting rod/control column bolt, missing nut, and interference between the forward control lever assembly and the structure. Compliance with the AD is mandatory for the aircraft to continue operations within the Commonwealth of Australia, and failure to adhere to the specified requirements can result in legal ramifications. This AD applies across the entire Commonwealth, as it is a national regulation issued under the authority of the Civil Aviation Regulations 1998. The Airworthiness Directive sets forth specific requirements and timeframes for compliance, with the directive becoming effective from 17 April 2002. Part A of the requirement document mandates that the inspection be carried out before further flight after this date. Part B of the requirement document requires the inspection to be completed within 15 days or at the next 50-hour inspection after 17 April 2002, whichever occurs first. The inspection must be conducted in accordance with VulcanAir Service Bulletin No. 111 Revision 1, as referenced in the AD. This Airworthiness Directive applies to all aircraft models and serial numbers specified within its purview and is enforceable under the Civil Aviation Regulations 1998.

Key Provisions

The Airworthiness Directive (AD) issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 (CAR 1998) pertains specifically to Partenavia P68 Series Aeroplanes, as outlined in AD/P68/50. The applicability section of the AD specifies that it applies to all Model P68 Observer 2 aircraft with serial numbers ranging from 401 through 413, as well as Model P68C aircraft with serial number 402. Additionally, it applies to all Model P68 aircraft up to and including serial number 413. This means that the directive is mandatory for a specific subset of aircraft within the P68 series, requiring them to adhere to the outlined inspection and repair requirements. The requirement section of the AD mandates that an inspection be conducted in accordance with VulcanAir Service Bulletin No. 111 Revision 1. This inspection is critical for addressing issues such as an incorrectly installed forward stabilator connecting rod/control column bolt and missing nuts, as well as interference between the forward control lever assembly and the aircraft structure. The AD references ENAC AD 2002-155, indicating a parallel directive issued by another aviation authority. The compliance section stipulates that Part A of the requirement document must be completed before further flight after 17 April 2002, while Part B must be undertaken within 15 days or at the next 50-hour inspection after the same date, whichever comes first. The AD imposes clear obligations on the operators and maintainers of the affected aircraft. They must ensure that the specified inspections and any necessary corrective actions are performed meticulously and within the prescribed timeframes. This includes verifying that the forward stabilator connecting rod/control column bolt is correctly installed, that no nuts are missing, and that there is no interference between the forward control lever assembly and the aircraft structure. Failure to comply with these requirements can lead to serious safety risks, including potential loss of control over the aircraft. Failure to adhere to the AD's requirements may result in serious consequences. The Civil Aviation Safety Authority (CASA) can impose penalties for non-compliance, which can include fines and other sanctions. Additionally, continued operation of an aircraft that does not meet the AD's requirements could result in the aircraft being grounded, preventing it from further flight until the required actions are completed. The potential penalties for breach of these regulations can be severe, reflecting the critical nature of ensuring airworthiness in the aviation industry.
