AD/LEARJET/11 - Lower Cabin Door Jamb - Inspection

Overview

The Civil Aviation Regulations 1998, as amended, are an integral part of Australia's aviation safety framework, governing various aspects of civil aviation operations, including aircraft maintenance and airworthiness. One particular legislative instrument, F2006B11127, was introduced to address specific safety concerns related to the Gates Learjet 24 and 25 series aeroplanes. Enacted by the Commonwealth of Australia, this regulation aims to ensure that these aircraft models comply with stringent safety standards, particularly focusing on the inspection of the lower cabin door jamb. The policy objective behind this directive is to prevent potential structural failures and ensure the safety of passengers and crew by mandating regular inspections within a specified timeframe. This legislative instrument is a component of the overarching Civil Aviation Regulations, reflecting the commitment to maintaining high safety standards within the Australian aviation industry. The enactment of F2006B11127 by the Commonwealth of Australia, under the Civil Aviation Regulations 1998, highlights the regulatory body's dedication to addressing specific safety deficiencies in certain aircraft models. This particular instrument targets the Gates Learjet 24 and 25 series aeroplanes, requiring inspections of the lower cabin door jamb to mitigate any risks associated with structural integrity. The regulation was implemented to ensure compliance within 100 hours of time in service after 31 July 1975, underscoring the importance of timely and regular maintenance checks. By incorporating this directive, the Civil Aviation Safety Authority aims to uphold the highest safety standards, thereby protecting the well-being of those involved in aviation activities.

Scope and Application

The Civil Aviation Safety Authority, under the Civil Aviation Regulations 1998, has issued specific airworthiness directives pertaining to Gates Learjet 24 and 25 series aeroplanes. These directives apply to certain serial numbers of the mentioned models, specifically Gates Learjet 24 with serial numbers ranging from 24-272 to 24-319 with the exclusion of 24-303, 24-304, and 24-305, and Gates Learjet 25 with serial numbers from 25-134 to 25-195 with a 24-inch door installed. This regulation is a Commonwealth instrument, binding across Australia and ensuring that these aircraft meet specified safety standards. The directive mandates an inspection of the lower cabin door jamb within 100 hours of time in service after 31 July 1975, as outlined in Gates Learjet Service Bulletin 24/25-260. Compliance with this directive is mandatory for the specified aircraft, ensuring that they adhere to the prescribed safety standards.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998 (CAR) Part 39 - 105, specifically the Airworthiness Directive (AD) concerning Gates Learjet 24 and 25 series aeroplanes, are outlined in AD/LEARJET/11. This directive mandates an inspection of the lower cabin door jamb for specific model numbers and serial ranges. For the Model 24, the serial numbers affected are 24-272, 24-295 to 319, excluding 24-303, 24-304, and 24-305. For the Model 25, the serial numbers covered are 25-134, 25-168 to 25-195, provided they are equipped with a 24-inch door. The directive references Gates Learjet Service Bulletin 24/25-260 as the document detailing the inspection requirements. Compliance with this directive is required within 100 hours of time in service following 31 July 1975. Entities and individuals governed by this directive are obligated to ensure that the specified inspections are conducted according to the referenced service bulletin. This includes adherence to the technical instructions and procedures outlined within Gates Learjet SB 24/25-260 to maintain the airworthiness of the aircraft. Failure to comply with the mandated inspection within the stipulated timeframe can lead to significant safety risks and potential non-compliance with regulatory standards. Breaching the requirements of this Airworthiness Directive can result in serious consequences. The AD is enforced to maintain the highest safety standards in civil aviation, and non-compliance may lead to enforcement actions. While the specific penalties are not detailed within this directive, non-compliance with CAR can generally lead to enforcement actions such as fines, suspension or revocation of aircraft certificates of airworthiness, and potentially criminal charges. The severity of the penalties can vary depending on the nature and extent of the non-compliance, with maximum penalties potentially including substantial financial fines and imprisonment for individuals found guilty of serious breaches.
