AD/ROBIN/20 - Main Gear Torque Link Attachment

Overview

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, incorporates an Airworthiness Directive (AD) concerning the Robin Aviation Series aeroplanes. The AD, titled "Main Gear Torque Link Attachment," was enacted to address safety concerns related to the attachment points of the strut torque link on certain Robin Aviation aircraft models, namely the HR100/250TR and HR100/285TR. The directive was introduced in response to field reports of cracks at these welded attachment points, as mandated by the French civil aviation authority, DGAC, through their AD 94-129(A). The Civil Aviation Safety Authority (CASA) subsequently adopted this directive to ensure the airworthiness of these aircraft in Australian airspace. Compliance with this AD is mandatory, requiring inspections to be carried out within 25 hours of the aircraft being in service after 8 December 1994 and at intervals specified in the applicable service bulletin, ensuring ongoing structural integrity and safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, applies to the maintenance and operation of Robin Aviation Series aeroplanes, including the model HR100/250TR and HR100/285TR. The scope of this legislation mandates that these aircraft must comply with Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). This includes the requirement to perform specific actions outlined in Avions Pierre Robin Service Bulletin 134, in response to identified issues such as cracks at the strut torque link welded attachment points, as directed by the French Directorate General for Civil Aviation (DGAC) in their AD 94-129(A). Compliance with these directives is mandatory unless the specified action has already been completed, with inspections required within 25 hours of the aircraft being in service after 8 December 1994 and at further intervals as detailed in the Requirement Document. The application of this Act is national and overseen by CASA, with the aim of ensuring the safety and airworthiness of the specified aircraft within Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, Section 105, outlines Airworthiness Directives (ADs) related to the safety of aircraft. One such directive, AD/ROBIN/20, pertains to the Robin Aviation Series Aeroplanes, particularly models HR100/250TR and HR100/285TR. This directive mandates actions to be taken in accordance with Avions Pierre Robin Service Bulletin 134, which references DGAC AD 94-129(A). The primary requirement of this directive is that an inspection must be conducted unless it has already been completed. This inspection must be carried out within 25 hours of time in service following 8 December 1994, and subsequently at intervals specified in the Requirement Document. This stems from the DGAC's requirement for an inspection in response to reports of cracks on the strut torque link welded attachment points. Under the Civil Aviation Regulations 1998, the obligations imposed on the parties governed by this directive are clear and specific. Aircraft owners and operators must ensure that the inspections and any necessary repairs or modifications are conducted in compliance with the AD/ROBIN/20 directive. This involves adhering to the instructions outlined in Avions Pierre Robin Service Bulletin 134, ensuring that the inspection is performed within the stipulated timeframe, and maintaining records of compliance. These obligations are crucial for maintaining the airworthiness of the aircraft and ensuring the safety of all personnel involved in flight operations. Breaches of the requirements set forth in the AD/ROBIN/20 directive can result in serious consequences. While the Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with specific ADs, general provisions within the regulations may apply. Non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). This may include the issuance of a Notice of Proposed Civil Penalty, which can result in significant financial penalties. Additionally, CASA has the authority to suspend or revoke airworthiness certificates if the aircraft is found to be operating in a non-airworthy condition, which could lead to grounding of the aircraft until the required actions are taken. The potential for these actions underscores the importance of adhering to the directive to avoid serious ramifications.
