AD/LEARJET/13 - Spoiler System - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive framework governing civil aviation activities within Australia. This legislation addresses the need for stringent safety standards and operational protocols to ensure the safe and efficient use of airspace and to protect the public from aviation-related risks. One particular aspect of these regulations, the Schedule of Airworthiness Directives, is crucial in maintaining the safety and airworthiness of specific aircraft models. The directive pertaining to Gates Learjet 24 & 25 Series Aeroplanes, specifically AD/LEARJET/13, focuses on the inspection of the spoiler system, which is critical for the safe operation of these aircraft. This directive applies to certain serial numbers of model 24 and 25 Learjet aeroplanes, ensuring that the specified aircraft meet the necessary safety standards as detailed in the relevant service bulletin (Gates Learjet SB 23/24/25-265). The objective of these directives is to maintain the highest safety standards and ensure compliance with civil aviation safety requirements.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, focusing on Gates Learjet 24 and 25 series aeroplanes. This legislation applies to certain serial numbered aircraft within these models, namely all model 24 with serial numbers 24-100 to 24-302 and 24-309 to 24-317, and all model 25 with serial numbers 25-003 to 25-194. The directive mandates an inspection of the spoiler system as stipulated in Gates Learjet Service Bulletin 23/24/25-265, with compliance required as per the detailed specifications in the referenced document. This regulation applies nationally, overseen by the Civil Aviation Safety Authority, and its enforcement ensures the continued airworthiness and safety of these specific aircraft models within Australia.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically PART 39 - 105, include an Airworthiness Directive (AD) for Gates Learjet 24 and 25 series aeroplanes, identified as AD/LEARJET/13. This directive pertains to the inspection of the spoiler system (section 9/75). The directive applies to specific serial numbers of these aircraft models: for model 24, the serial numbers range from 24-100 to 24-302 and 24-309 to 24-317, and for model 25, from 25-003 to 25-194. The requirement for compliance is documented in Gates Learjet SB 23/24/25-265, which outlines the specific inspection procedures and standards that must be followed. The AD imposes several obligations on the parties or entities it governs. Primarily, it mandates that the specified Gates Learjet 24 and 25 aircraft undergo a thorough inspection of their spoiler systems. This inspection is crucial to ensure that the aeroplanes maintain their airworthiness and comply with safety standards set by the Civil Aviation Safety Authority (CASA). Operators and maintenance providers are required to adhere to the detailed instructions provided in the Gates Learjet Service Bulletin SB 23/24/25-265, which includes specific steps for the inspection and any necessary corrective actions. Failure to comply with the AD/LEARJET/13 directive may result in significant legal consequences. Non-compliance with airworthiness directives is considered a serious matter under aviation law. Operators who do not ensure that their aircraft meet the specified inspection requirements can face penalties, including fines and potential grounding of the aircraft. In severe cases, CASA may take enforcement action that could lead to criminal charges. The exact penalties for non-compliance are not detailed in the provided text, but they can be substantial, reflecting the critical nature of maintaining aircraft safety standards.
