Overview
The Civil Aviation Safety Authority (CASA) enacted the Civil Aviation Regulations 1998, specifically Part 39 - 105, to address safety concerns and ensure the airworthiness of aircraft in Australia. This regulation aims to provide detailed safety directives for particular aircraft models, including the Twin Commander (Gulfstream/Rockwell/ Aerocommander 500, 600 and 700) series aeroplanes. The directive under focus pertains to the inspection and replacement of wing spar fillet screws, as outlined in AD/AC/65. The policy objective is to maintain and enhance aviation safety by ensuring that specific aircraft components meet stringent safety standards. Compliance with these directives is mandatory for the specified aircraft models to prevent potential safety hazards and ensure the reliability and airworthiness of these aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, which is pivotal in ensuring the safety and airworthiness of aircraft operating within Australian airspace. This particular legislative instrument pertains to the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600 and 700) Series Aeroplanes, mandating a rigorous inspection and replacement process for wing spar fillet screws. The directive applies to specific serial numbers of the aircraft models 685 and 690, 690A, and 690B, with certain exceptions noted in Rockwell International SB No. 164. The inspections are required within 100 hours of time in service following 1 March 1978, and subsequently at intervals not exceeding 100 hours’ time in service until the screws are replaced according to the specifications detailed in the referenced service bulletin. This regulation ensures that the specified aircraft meet stringent safety standards and are maintained in a condition fit for operation within Australia.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, detail the requirements for the inspection and replacement of wing spar fillet screws for certain models of Twin Commander aeroplanes. This applies to all model 685 aeroplanes with serial numbers ranging from 12000 to 12066, and all models 690, 690A, and 690B except those serial numbers listed in Rockwell International Service Bulletin (SB) No. 164 (sections 1/78). The directive mandates an inspection within 100 hours of time in service after 1 March 1978, and subsequent inspections must be carried out at intervals not exceeding 100 hours of time in service until the screws are replaced as per the requirement document.
Entities governed by these regulations must ensure that the inspections and any necessary replacements are performed in accordance with the specified intervals. This involves rigorous compliance with the schedule set forth in the Rockwell International SB No. 164, which serves as the compliance document for these directives. Compliance is critical to maintaining the airworthiness of these aircraft, ensuring safety standards are upheld, and preventing any potential structural failures.
Failure to comply with these airworthiness directives can result in significant legal and safety consequences. The Civil Aviation Regulations 1998 impose stringent obligations on operators and owners to adhere to these directives. Non-compliance can lead to enforcement actions, including potential grounding of the aircraft, which could result in operational disruptions and financial losses. Additionally, CASA has the authority to impose administrative penalties, and in severe cases, criminal charges could be brought against individuals or entities responsible for the non-compliance. The exact penalties for breaches of these regulations are not detailed in the provided excerpt but can include substantial fines and other sanctions as prescribed by the Civil Aviation Act 1988 and related legislation.
