COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
DHC-6 (Twin Otter) Series Aeroplanes
AD/DHC-6/6 Tailplane Attachment Bolts - Modification 10/67
Applicability: All models with S/Nos. 1 to 63.
Document: De Havilland of Canada Mod. Bulletin 6/1114. Compliance: Before 1 January 1968.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address the need for stringent and updated regulations concerning civil aviation safety to ensure the safety of passengers, crew, and the general public. This legislative instrument is a part of a broader framework that aims to maintain the highest standards in civil aviation safety across Australia. One specific area of focus within this legislation is the regulation of airworthiness directives, which are mandatory orders issued by the Civil Aviation Safety Authority (CASA) to address identified safety issues with specific aircraft types. The policy objective of these regulations is to mitigate risks associated with aircraft operation by ensuring that all aircraft conform to safety standards and are maintained in a condition that allows for safe operation.
The specific legislative instrument F2006B09147 pertains to airworthiness directives for DHC-6 (Twin Otter) Series Aeroplanes, particularly addressing modifications to the tailplane attachment bolts. This directive applies to all models with serial numbers 1 to 63, and compliance is required before 1 January 1968. This regulation was introduced to ensure that any identified issues with the tailplane attachment bolts are rectified, thereby enhancing the overall safety and airworthiness of the affected aircraft. The Civil Aviation Regulations 1998, through such specific directives, play a critical role in maintaining and improving aviation safety standards in Australia.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 – 105, applies to all DHC-6 (Twin Otter) series aeroplanes with serial numbers 1 to 63, mandating modifications to the tailplane attachment bolts as per De Havilland of Canada Modification Bulletin 6/1114. These regulations are enforced by the Civil Aviation Safety Authority (CASA) and have a Commonwealth reach, applying uniformly across Australia. Compliance with these airworthiness directives is mandatory, and the required modifications must be implemented before 1 January 1968 for all specified aircraft models. The legislation does not explicitly state exclusions or exemptions, and its application may be extended or clarified through subordinate instruments issued by CASA. The regulations aim to ensure the safety and airworthiness of the specified DHC-6 aircraft models by addressing potential structural issues through mandated modifications.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, particularly Part 39 - 105, mandate specific modifications to the tailplane attachment bolts of DHC-6 (Twin Otter) Series Aeroplanes. Section 39-105, in the context of Airworthiness Directives (AD), requires all DHC-6 aircraft with serial numbers (S/Nos.) ranging from 1 to 63 to undergo a modification to the tailplane attachment bolts (section 10/67). This directive is outlined in the De Havilland of Canada Modification Bulletin 6/1114 and must be complied with before 1 January 1968.
The obligations imposed by this legislation on the parties or entities it governs include ensuring that the specified modifications are completed by the stipulated date. This involves the aircraft owner, operator, or any authorised maintenance personnel conducting the required inspection and modification of the tailplane attachment bolts as detailed in the referenced document. Compliance with these directives is mandatory to maintain the airworthiness of the aircraft, ensuring safety standards are upheld.
Should there be any breach of the requirements outlined in the Civil Aviation Regulations 1998, particularly the modifications specified in Section 39-105, there could be significant consequences. The Act provides for both civil and criminal penalties for non-compliance. Civil penalties can include fines up to a maximum of $1,000,000 for corporations and $200,000 for individuals, as stipulated under Section 13AB of the Civil Aviation Act 1988. Additionally, criminal offences for non-compliance can result in imprisonment for up to five years, reflecting the seriousness with which the regulation of air safety is treated.
