AD/MU-2/12 - Nose Landing Gear Shimmy Damper - Inspection

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, was enacted to establish and maintain airworthiness standards for aircraft, ensuring the safety and reliability of commercial and private aviation within Australia. The Mitsubishi MU-2 Series Aeroplanes Nose Landing Gear Shimmy Damper Inspection directive (AD/MU-2/12) was introduced to address specific safety concerns related to the nose landing gear shimmy damper in Mitsubishi MU-2 aircraft. This directive was created to comply with international standards and ensure the safety of these aircraft by mandating inspections within a specified timeframe to prevent potential operational hazards. This legislative instrument was enacted by the Australian Government to ensure that all civil aviation activities adhere to rigorous safety standards, overseen by the Civil Aviation Safety Authority (CASA). The policy objective is to maintain the highest level of safety in civil aviation, thereby protecting the public, crew, and passengers from potential risks associated with aircraft operations.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to all Mitsubishi MU-2 Series aeroplanes operating within Australia, ensuring adherence to the specific airworthiness directives issued by the Civil Aviation Safety Authority. These directives, which are enforced under the authority granted by the Civil Aviation Act 1988, mandate that all operators of the Mitsubishi MU-2 Series must comply with the inspection requirements of the nose landing gear shimmy damper as outlined in either Mitsubishi SB No. 169 or Japan Civil Aviation Bureau AD No. TCD-1209-75. Compliance with these directives is mandatory, with inspections to be carried out within 25 hours of time in service after 13 November 1975. The regulations extend their application to all relevant models of the Mitsubishi MU-2 Series, ensuring a standardised approach to aviation safety across the Commonwealth.

Key Provisions

The primary operative section of the Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. The directive AD/MU-2/12 addresses the nose landing gear shimmy damper on Mitsubishi MU-2 Series Aeroplanes (section 1). This directive mandates that the inspection of the nose landing gear shimmy damper must be performed within 25 hours of time in service after 13 November 1975. The applicable documents for compliance are Mitsubishi SB No. 169 or Japan Civil Aviation Bureau AD No. TCD-1209-75 (section 11/75). The obligations and requirements imposed by this directive are clear and precise. Operators of Mitsubishi MU-2 Series Aeroplanes must ensure that the nose landing gear shimmy damper is inspected within the specified timeframe. This inspection must be in accordance with the guidelines set out in either Mitsubishi SB No. 169 or Japan Civil Aviation Bureau AD No. TCD-1209-75. Failure to comply with this directive could result in serious safety implications, thus it is imperative that operators adhere strictly to these requirements. Failure to comply with the requirements set out in AD/MU-2/12 can lead to various consequences. The primary concern is the potential risk to flight safety, as the nose landing gear shimmy damper plays a critical role in the stability and control of the aircraft during landing. Non-compliance with this directive could result in enforcement actions by CASA, which may include fines, operational restrictions, or even grounding of the affected aircraft until compliance is achieved. The regulations do not specify maximum penalties within the text, but such enforcement actions are designed to ensure that all operators take the necessary steps to maintain airworthiness and safety standards. The consequences for non-compliance extend beyond potential fines and operational restrictions. Operators found in breach of this directive may also face legal repercussions, including civil or criminal charges, depending on the severity of the non-compliance and its impact on aviation safety. These legal consequences underscore the importance of adhering to the directive and maintaining the airworthiness of the aircraft. It is essential for operators to stay informed and up-to-date with CASA directives to avoid any potential legal and safety issues.
