AD/MU-2/16 - Main Landing Gear Drag Strut - Inspection

Overview

The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, which addresses the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives, was enacted to ensure that aircraft operating in Australian airspace meet stringent safety standards. This legislation was introduced to address the need for a comprehensive regulatory framework that mandates regular safety checks and compliance with specified maintenance and operational standards. The objective of this regulation, as stated, is to ensure the highest possible safety standards are maintained for aircraft, thus protecting the public and enhancing the integrity of the aviation industry. The Civil Aviation Regulations 1998 were enacted by the Parliament of Australia and are administered by CASA, which is responsible for enforcing compliance and setting safety directives to mitigate aviation risks.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which mandate the compliance of aircraft with certain safety standards. This particular regulation, AD/MU-2/16, is applicable to Mitsubishi MU-2 Series Aeroplanes with serial numbers ranging from 005 to 337 and 501 to 692. The directive necessitates an inspection of the main landing gear drag strut, as outlined in Mitsubishi Service Bulletin No. 173, and must be completed within 100 hours of time in service after 31 May 1976. The scope of this legislation is targeted at ensuring the continued airworthiness of specified Mitsubishi MU-2 models by addressing potential safety concerns related to the main landing gear drag strut. While the regulation itself does not explicitly detail geographic or jurisdictional reach beyond the specified aircraft models and their compliance timeframes, it is inherently subject to the broader regulatory framework of Australian civil aviation law, which operates under the Commonwealth jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, provides specific safety directives for Mitsubishi MU-2 Series Aeroplanes, particularly focusing on the Main Landing Gear Drag Strut. Section (AD/MU-2/16) mandates that all models with serial numbers (S/Nos.) ranging from 005 to 337 and 501 to 692 must comply with these directives. Compliance is achieved through the Mitsubishi Service Bulletin No. 173, which outlines the necessary procedures for inspecting the main landing gear drag strut. This regulation imposes a requirement on the operators of the specified Mitsubishi MU-2 Series Aeroplanes to conduct an inspection of the main landing gear drag strut within 100 hours of time in service after 31 May 1976. The aim is to ensure that the drag struts are in proper working condition, thereby enhancing the safety and reliability of the aircraft during landing operations. The operators must document and record the inspections in accordance with the directives provided in the Mitsubishi Service Bulletin No. 173. Failure to comply with the requirements outlined in Section (AD/MU-2/16) can result in serious consequences. Under the Civil Aviation Regulations 1998, non-compliance may lead to the aircraft being considered unairworthy, which can result in grounding of the aircraft until the necessary inspections are performed and documented. Operators found in breach of these safety directives may face regulatory action, including fines and potential criminal charges. The maximum penalties can include substantial fines and imprisonment for individuals responsible for the oversight or operation of the non-compliant aircraft. These provisions are in place to ensure that all operators adhere strictly to the safety standards set forth by the Civil Aviation Safety Authority.
