AD/DC4/5 - Cap Bolts - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were established to ensure the safe operation of aircraft within the country's airspace. A specific legislative instrument within this framework, F2006B08848, pertains to the Airworthiness Directives for the Douglas DC4 Series Aeroplanes, specifically targeting the replacement of cap bolts. This directive was introduced to address safety concerns related to the structural integrity of the aircraft, ensuring that all Douglas DC4 Series Aeroplanes comply with stringent safety standards. The policy objective outlined within this legislative instrument is to enhance aviation safety by mandating the replacement of cap bolts, thereby mitigating potential risks associated with aircraft operation. The enactment of this directive by the Civil Aviation Safety Authority underscores a commitment to maintaining high safety standards in civil aviation. By aligning with international directives such as the FAA AD 49-38-2 and referencing the Australian National Standard ANO 105.1.16.2.5.4, the legislation ensures that the safety measures are both robust and internationally recognised. This regulatory approach helps to protect passengers, crew, and the general public from the risks associated with aircraft malfunctions, thereby reinforcing the overall safety framework within Australia's civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 – 105, pertain specifically to airworthiness directives issued by the Civil Aviation Safety Authority (CASA). The scope of this particular legislative instrument, AD/DC4/5, applies to the replacement of cap bolts on Douglas DC4 Series aeroplanes. The regulation is directed at operators, maintenance personnel, and other entities involved in the operation and maintenance of these aircraft. The regulation ensures that the specified cap bolts are replaced to maintain the structural integrity and airworthiness of the aircraft, thereby enhancing safety standards in civil aviation. The jurisdiction of this regulation is national, applying across the Commonwealth of Australia, and it is enforced by CASA, the regulatory body for civil aviation safety in the country. There are no stated exclusions or exemptions within the text provided, suggesting that the directive applies universally to all relevant aircraft within the specified series operating within Australia. The regulation may also extend its application through subordinate instruments that CASA may issue to provide further detail or operational guidance.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998 (CARs) in PART 39 - 105 specifically address the airworthiness directives for Douglas DC4 Series aeroplanes. Section 39.105 pertains to the replacement of cap bolts, with reference to AD/DC4/5. This section mandates that operators of Douglas DC4 aeroplanes must adhere to the instructions provided in either the Douglas Service August 1947, FAA AD 49-38-2, or ANO 105.1.16.2.5.4, which are recognised as authoritative documents for the replacement of these cap bolts to ensure compliance with airworthiness standards. These regulations impose several obligations on the parties or entities governed by them. Primarily, operators of the Douglas DC4 aeroplanes must ensure that all specified cap bolts are replaced according to the referenced documents. This involves conducting thorough inspections, identifying any cap bolts that need replacement, and executing the replacement process in accordance with the detailed procedures outlined in the authoritative documents. Operators must also maintain accurate records of these inspections and replacements, as documentation is critical for compliance verification and safety audits. Failure to comply with the airworthiness directives set out in these regulations can result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and non-compliance may lead to enforcement actions. In terms of civil consequences, operators may face fines, which under the Civil Aviation Act 1988 can reach up to $210,000 for individuals and $1,050,000 for corporations, depending on the severity and frequency of the breach. Furthermore, continued non-compliance can result in the grounding of the aircraft, which would effectively halt operations until the necessary compliance measures are undertaken. In extreme cases, criminal charges may be brought against responsible individuals, leading to potential imprisonment. It is crucial for operators to take these directives seriously to avoid the severe penalties associated with non-compliance.
