Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, were established to regulate and ensure the safety of civil aviation activities within Australia. One component of these regulations, as detailed in PART 39 - 105, pertains to airworthiness directives for specific aircraft types, including the Mitsubishi MU-2 Series Aeroplanes. Specifically, AD/MU-2/13 mandates the inspection of the main landing gear forward door emergency cable for certain MU-2B-30 and MU-2B-35 models, with particular serial number ranges, to address potential safety concerns. This directive aims to ensure that these aircraft maintain their airworthiness and operational safety by adhering to specified inspection intervals. The policy objective is to maintain the highest safety standards in Australian civil aviation by providing clear, actionable directives for aircraft maintenance and operation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to the Mitsubishi MU-2 Series aeroplanes, with a focus on models MU-2B-30 with serial numbers ranging from 502 to 547, and MU-2B-35 with serial numbers ranging from 501 to 615, provided they are not fitted with Cable Part Number 030A-38558-41/51. This legislation pertains to the inspection of the main landing gear forward door emergency cable, as stipulated in AD/MU-2/13 11/75, and mandates compliance within 100 hours of time in service after 31 December 1975, with subsequent inspections occurring at intervals not exceeding 100 hours of time in service. The regulation's application is enforced nationwide, ensuring safety standards are uniformly maintained across all states and territories within the Commonwealth of Australia.
Key Provisions
The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 (section 105) concerning the Mitsubishi MU-2 Series Aeroplanes, specifically targeting the Main Landing Gear Forward Door Emergency Cable (AD/MU-2/13 11/75). The directive applies to all MU-2B-30 models with serial numbers (S/Nos.) ranging from 502 to 547, and MU-2B-35 models with S/Nos. 501 and 548 to 615, excluding those equipped with Cable P/N 030A-38558-41/51. The directive mandates that Mitsubishi SB No. 170 must be followed for compliance. Operators are required to inspect the specified component within 100 hours of time in service after 31 December 1975, and subsequently, at intervals not exceeding 100 hours of time in service.
Operators of affected aircraft must adhere to stringent maintenance protocols as outlined in the Mitsubishi SB No. 170. This involves conducting thorough inspections of the Main Landing Gear Forward Door Emergency Cable to ensure its structural integrity and functionality. These inspections are crucial in preventing potential failures that could compromise the safety of the aircraft during operation. The frequency of these inspections, mandated within 100 hours of time in service following the directive's issuance and thereafter at intervals not exceeding 100 hours, underscores the importance of regular maintenance to uphold airworthiness standards.
Failure to comply with the provisions of AD/MU-2/13 11/75 could result in severe consequences. The Civil Aviation Regulations 1998 impose strict obligations on operators to ensure that all maintenance and inspection requirements are met. Non-compliance may lead to enforcement actions by CASA, which can include imposing fines, penalties, and potentially grounding the aircraft. The severity of these penalties reflects the critical nature of adhering to airworthiness directives, highlighting the paramount importance of safety in aviation operations. Operators are therefore required to meticulously document and record all inspections and maintenance activities to demonstrate compliance with the regulatory requirements.
