AD/LEARJET/2 - Spoiler Actuator Attachment Bolts - Replacement

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the framework under which airworthiness directives are issued by the Civil Aviation Safety Authority (CASA). This legislative instrument, F2006B11136, was enacted to ensure that civil aviation operations maintain high safety standards, addressing potential risks associated with specific aircraft components. This particular regulation pertains to the Gates Learjet 24 and 25 series aeroplanes, aiming to mitigate safety issues by mandating the replacement of spoiler actuator attachment bolts, as detailed in Gates Learjet Service Bulletin No. 24/25-237B. The policy objective of these regulations is to enhance aviation safety by ensuring that all applicable aircraft meet the necessary safety standards. The authority to enact and enforce these regulations lies with the Australian Parliament, ensuring compliance and adherence to safety protocols across the industry.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued an airworthiness directive under the Civil Aviation Regulations 1998, specifically within Part 39-105, which mandates the replacement of spoiler actuator attachment bolts for Gates Learjet 24 and 25 series aeroplanes. This directive applies to all model 24 aircraft with serial numbers ranging from 24-178 to 24-268, and model 25 aircraft with serial numbers from 25-020 to 25-114. The directive is enforced to ensure the continued airworthiness of these aircraft by addressing a critical safety issue identified in Gates Learjet Service Bulletin No. 24/25-237B. Compliance with this directive is mandatory for the specified aircraft models and serial numbers, and it must be carried out as per the detailed requirements outlined in the referenced service bulletin. The directive is applicable across the Commonwealth of Australia, ensuring a consistent approach to aircraft safety regulation throughout the nation.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, addresses the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, with a particular focus on Gates Learjet 24 and 25 series aeroplanes. One of the key provisions in this section is AD/LEARJET/2, which mandates the replacement of spoiler actuator attachment bolts in certain model 24 and 25 aeroplanes (section 39-105). The directive applies to all model 24 aeroplanes with serial numbers (S/Nos.) ranging from 24-178 to 24-268 and all model 25 aeroplanes with S/Nos. from 25-020 to 25-114. This requirement is detailed in Gates Learjet Service Bulletin No. 24/25-237B and compliance must be achieved as per the specified instructions in the requirement document. The obligations imposed by this legislation on the relevant parties include ensuring that the specified spoiler actuator attachment bolts are replaced in the identified aircraft. This involves thorough inspection of the affected aeroplanes to verify their serial numbers and the condition of the spoiler actuator attachment bolts. Once identified, the replacement must be carried out by authorised personnel following the procedures outlined in the requirement document. Compliance with these directives is crucial to maintaining the airworthiness of the affected aircraft and ensuring the safety of all passengers and crew. Failure to comply with the airworthiness directives stipulated in the Civil Aviation Regulations 1998 can result in significant legal consequences. If an entity or individual fails to replace the spoiler actuator attachment bolts as required, it could lead to enforcement actions by CASA. The potential penalties for non-compliance can include fines, enforcement notices, and in severe cases, the grounding of the aircraft. The exact penalties are not specified in the extract but could range from civil to criminal liabilities depending on the severity and impact of the non-compliance. It is imperative for all stakeholders to adhere to these directives to avoid such repercussions and ensure the highest standards of aviation safety are maintained.
