Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve to regulate civil aviation activities and ensure the safety and efficiency of aviation operations. The regulations address various aspects of civil aviation, including the airworthiness of aircraft. Part 39 of these regulations, specifically addressing Airworthiness Directives, is instrumental in maintaining the safety standards of aircraft in operation. One such directive, AD/LEARJET/10, pertains to Gates Learjet 24 & 25 Series Aeroplanes, focusing on the inspection of spoiler centre hinge brackets to ensure they meet specified safety standards. This directive was introduced to address potential safety issues identified with certain Learjet models, ensuring that the aircraft remain airworthy and compliant with safety regulations. The policy objective behind such directives is to safeguard the integrity and safety of the aircraft and its occupants by mandating regular inspections and necessary repairs.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, which deals with airworthiness directives issued by the Civil Aviation Safety Authority (CASA), applies to specific series of Gates Learjet aeroplanes. The regulation mandates inspections of spoiler centre hinge brackets on Learjet 24 and 25 series aeroplanes. It applies to Learjet 24 models with serial numbers ranging from 24-100 to 24-301, 24-309, 24-310, 24-313, and 24-314, as well as Learjet 25 models with serial numbers from 25-002 to 25-185. The directive requires compliance within the next 100 hours of time in service after 31 July 1975, as outlined in Gates Learjet Service Bulletin 23/24/25-262. This regulation is part of the Commonwealth of Australia’s framework and operates under the jurisdiction of CASA, ensuring that these specific aircraft models meet required safety standards. The regulation's scope is limited to the specified models and serial numbers, and compliance is to be verified according to the specified timeframe and documentation.
Key Provisions
The primary operative sections of this legislation are found within AD/LEARJET/10, which focuses on the inspection of spoiler centre hinge brackets on Gates Learjet 24 and 25 series aeroplanes. Specifically, Section 6/75 requires that certain model numbers of these aircraft must undergo an inspection of their spoiler centre hinge brackets. The applicable models are the Gates Learjet 24 series with serial numbers ranging from 24-100 to 24-301, excluding 24-302 to 24-308, and including 24-309 to 24-314. For the Gates Learjet 25 series, the serial numbers from 25-002 to 25-185 are covered. This directive is to be complied with within the next 100 hours of time in service after 31 July 1975.
The Act imposes specific obligations on the operators and owners of the affected aircraft. These parties must ensure that the required inspections of the spoiler centre hinge brackets are conducted in accordance with the specifications provided in Gates Learjet Service Bulletin 23/24/25-262. Failure to comply with these inspection requirements could result in the aircraft being deemed unairworthy, thus prohibiting its operation until the necessary inspections and any required repairs have been completed.
There are no specific offences, penalties, or civil/criminal consequences mentioned in the text for non-compliance with the inspection requirements. However, the overarching principle of the Civil Aviation Regulations 1998 is that non-compliance with airworthiness directives can lead to severe repercussions, including potential fines, suspension or revocation of aircraft certificates, and criminal charges if the non-compliance results in safety incidents or accidents. The maximum penalties for such offences can vary widely depending on the severity of the breach and the specific provisions of the Civil Aviation Act 1988. It is essential for operators and owners to adhere to these directives to maintain the safety and airworthiness of their aircraft.
