Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation within Australia. The regulations are administered by the Civil Aviation Safety Authority (CASA) and are designed to maintain a high standard of safety for all civil aviation activities. Part 39 - 105 of these regulations specifically addresses Airworthiness Directives, which are legally enforceable rules that are essential for ensuring aircraft safety. This part includes directives such as AD/LEARJET 35/13, which targets the modification of upper cabin door lock mechanism bolts for Gates Learjet 35 and 36 series aeroplanes. The directive was introduced to address the identified safety issue with the lock mechanism, ensuring that the aircraft comply with the necessary safety standards to prevent potential in-flight hazards. The policy objective behind these regulations is to ensure the highest safety standards in civil aviation by mandating specific modifications and compliance measures. For example, AD/LEARJET 35/13 requires that the upper cabin door lock mechanism bolts are modified by installing a Gates Learjet Kit No. AMK 79-9. This modification, which includes the installation of drilled bolts and lockwiring, must be completed within 150 hours of time in service after 30 April 1980. This directive ensures that the affected aircraft maintain the necessary safety features, thereby reducing the risk of in-flight incidents.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, applies to the Gates Learjet 35 and 36 Series Aeroplanes, targeting particular serial numbers within these models. The legislation mandates that aircraft owners or operators of model 35 with serial numbers ranging from 35-001 to 35-274 and 35-278, as well as model 36 with serial numbers ranging from 36-001 to 36-044, must modify the upper cabin door lock mechanism bolts. This directive is issued by the Civil Aviation Safety Authority (CASA) and requires compliance within 150 hours of time in service after 30 April 1980. The modification involves installing the Gates Learjet Kit No. AMK 79-9, which includes the installation of drilled bolts and lockwiring these bolts in-situ to enhance the safety of the upper cabin door lock mechanism. This legislative instrument applies across the Commonwealth of Australia and its application may be extended or restricted through subordinate instruments as necessary.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, under the authority of the Civil Aviation Safety Authority (CASA), mandates specific airworthiness directives for Gates Learjet 35 and 36 Series aeroplanes. Notably, AD/LEARJET 35/13 pertains to the modification of upper cabin door lock mechanism bolts. This directive applies to all model 35 aeroplanes with serial numbers (S/Nos.) ranging from 35-001 to 35-274 and 35-278, and all model 36 aeroplanes with S/Nos. from 36-001 to 36-044.4/80 (section 39 - 105). The requirement is to modify the upper cabin door lock mechanism bolts by installing the Gates Learjet Kit No. AMK 79-9. This installation should be completed within 150 hours of time in service after 30 April 1980 (section 39 - 105). This directive imposes specific obligations on the operators and owners of the affected aircraft. They must ensure that the modifications to the upper cabin door lock mechanism bolts are carried out as specified, using the prescribed Gates Learjet Kit No. AMK 79-9. This involves installing the kit's components and properly lockwiring the bolts in-situ to enhance safety. The modification must be completed within the stipulated timeframe, i.e., within 150 hours of time in service following 30 April 1980. Failure to comply with this directive can result in serious safety implications and potential regulatory consequences. The Civil Aviation Regulations 1998 include provisions for addressing breaches of airworthiness directives. Should an operator or owner fail to comply with the requirements of AD/LEARJET 35/13, they may be subject to enforcement actions by CASA. The penalties for non-compliance can include administrative penalties, enforcement notices, or even the grounding of the aircraft until the required modifications are completed. Additionally, persistent non-compliance could lead to more severe consequences, such as the suspension or revocation of the aircraft's airworthiness certificate. The exact penalties and consequences would be determined based on the severity and frequency of the non-compliance, as well as the potential risk posed to aviation safety.
