Overview

The Civil Aviation Regulations 1998, as amended by the Airworthiness Directive (AD/P68/51), were enacted to address safety concerns specific to Partenavia P68 Series Aeroplanes, namely issues with the flight controls. This legislation was introduced by the Civil Aviation Safety Authority (CASA) to ensure the safety of these aircraft by mandating corrective actions in response to reported instances of interference between the control column interconnection chain and the engine control pedestal assembly. This interference could arise from incorrect longitudinal pitch control rigging adjustments or excessive nose-down pressure beyond the stabilator torque tube full-travel limit. The AD requires specific inspections and modifications as outlined in VulcanAir Service Bulletin No. 110, dated 19 March 2002, to be carried out by all operators of P68 Observer, Observer 2, and P68TC Observer aircraft with serial numbers up to and including 411. Compliance with these directives is critical for maintaining airworthiness and ensuring safe flight operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the issuance of Airworthiness Directives by the Civil Aviation Safety Authority (CASA) to address identified safety issues in certain aircraft. This legislative instrument applies to all Partenavia P68 series aeroplanes, including the Observer, Observer 2, and P68TC Observer models with serial numbers up to and including 411. The directive is issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, which empowers the CASA delegate to ensure corrective actions are taken to mitigate unsafe conditions. Compliance with this directive requires specific actions, as outlined in the directive, to be undertaken by the relevant aircraft operators or owners. This includes an inspection before further flight after 24 April 2002 and a modification by 24 May 2002, unless these actions have already been completed. The directive becomes effective from 24 April 2002 and is designed to address potential interference issues between the control column interconnection chain and the engine control pedestal assembly, which could arise from incorrect rigging adjustments or excessive nose-down pressure application.

Key Provisions

The Civil Aviation Regulations 1998 (CAR 1998) establish several operative sections that pertain to airworthiness directives. Specifically, section 39.1 (1) empowers a delegate of the Civil Aviation Safety Authority (CASA) to issue an Airworthiness Directive (AD) when it is deemed necessary to correct an unsafe condition (section 39.1(1)). In this context, AD/P68/51 pertains to all Partenavia P68 Observer, Observer 2, and P68TC Observer aircraft with serial numbers up to and including 411. This directive requires specific actions to be taken in relation to flight controls, in accordance with the instructions provided by VulcanAir Service Bulletin No. 110, dated 19 March 2002. The AD was issued on 24 April 2002 and became effective on the same date. Under the AD, there are distinct obligations imposed on the parties or entities governed by the Act. Primarily, the directive mandates that an inspection be conducted before further flight after 24 April 2002, unless it has already been completed. Additionally, any modifications required by the directive must be carried out not later than 24 May 2002, again unless already accomplished. These obligations are intended to ensure that the specified aircraft meet the safety standards set forth in the AD. Failure to comply with the AD may result in various legal consequences. While the specific penalties for non-compliance are not detailed within the text of the AD itself, under CAR 1998, non-compliance with an AD can lead to civil or criminal penalties. In cases of civil liability, the penalties may include fines or other civil sanctions. Criminal penalties can include imprisonment, fines, or both, depending on the severity of the breach and the discretion of the court. The exact penalties would be determined in the context of a legal proceeding following a breach of the AD.
