AD/DO-27/9 - Front Seat Restraint Installation - Modification

Overview

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, include a legislative instrument F2006B09304 that addresses the airworthiness of Dornier DO-27 Series aeroplanes. This instrument, enacted by the Commonwealth of Australia, targets the critical safety concern of ensuring that all models of the Dornier DO-27 Series aeroplanes have adequate restraint systems for front-seat occupants. The problem it was introduced to address is the need for improved safety measures for pilots and co-pilots, reducing the risk of injury during flight operations. The policy objective outlined in the regulation is to mandate modifications to the front seat restraint installations by requiring the fitting of safety harnesses that meet approved standards. The compliance deadline set for these modifications was before 1 October 1973, ensuring that all affected aircraft meet the new safety requirements within a specified timeframe.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 – 105, mandate the installation of safety harnesses for front seat restraints in Dornier DO-27 Series aeroplanes. This directive applies universally to all models within the specified series, ensuring that each aircraft complies with the stringent safety standards set forth by the Civil Aviation Safety Authority (CASA). The regulation necessitates that the installation of the safety harness be conducted according to a scheme approved by the Secretary, with guidance provided in the Airworthiness Advisory Circular No. 62 dated March 1972. Compliance with these safety directives is mandatory and must be achieved before 1 October 1973, underscoring the importance of timely adherence to aviation safety protocols. This legislation reflects the Commonwealth’s commitment to maintaining high safety standards across the aviation industry, impacting all operators and owners of the Dornier DO-27 Series aeroplanes within the national jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, under PART 39 - 105, specifically address the airworthiness directives for certain aircraft types, including the Dornier DO-27 Series Aeroplanes. One such directive, AD/DO-27/9, pertains to the modification of the front seat restraint installation (Section 105). According to this directive, all models of the Dornier DO-27 Series must have their front seat restraint installations modified by fitting a safety harness. This modification must adhere to an installation scheme that is approved by the Secretary (Section 105(1)). The guidelines for these installation schemes are detailed in Airworthiness Advisory Circular No. 62 dated March 1972. The Civil Aviation Regulations impose specific obligations on the operators and owners of Dornier DO-27 Series Aeroplanes. They must ensure that the required modifications to the front seat restraint installations are completed before the specified compliance date, which is 1 October 1973. This includes obtaining approval for the installation scheme from the Secretary and implementing the modifications as per the approved guidelines (Section 105(2)). Operators and owners must also maintain records demonstrating compliance with these requirements, as this is part of the broader framework for ensuring the safety and airworthiness of the aircraft. Failure to comply with the provisions outlined in AD/DO-27/9 may result in various consequences. The Civil Aviation Regulations provide for both civil and criminal penalties for non-compliance with airworthiness directives. For instance, an operator or owner who fails to complete the required modifications by the compliance date may face civil penalties, including fines. The specific amount of the fine is not detailed in the provided text but is subject to the general penalty provisions under the Civil Aviation Act 1988. Additionally, continued operation of a non-compliant aircraft may lead to enforcement actions, including the grounding of the aircraft until the required modifications are made. In severe cases, non-compliance could also result in criminal charges, particularly if the failure to comply has led to safety incidents or accidents. The maximum penalties for such offences are determined by the courts and can include substantial fines and imprisonment, depending on the severity of the breach and its consequences.
