AD/LEARJET 35/6 - Wing to Fuselage Attachment - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, were established to regulate and ensure the safety of civil aviation within Australia. One of the key pieces of legislation under these regulations is the Airworthiness Directives, which address specific issues related to the maintenance and safety of aircraft. The particular legislative instrument F2006B11121 pertains to the Gates Learjet 35 and 36 series aeroplanes, aiming to rectify safety concerns associated with the wing to fuselage attachment. This directive was introduced to ensure that these aircraft models meet the necessary safety standards, thereby reducing the risk of in-flight failures. The policy objective is clearly to enhance the overall safety of these specific aircraft models by mandating specific modifications to their design, as stipulated in the Airworthiness Directives.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Gates Learjet 35 and 36 series aeroplanes, with particular attention to those models meeting the specified serial numbers. This regulation pertains to the modification of the wing to fuselage attachment for certain Gates Learjet aircraft, mandating compliance with Gates Learjet Kit No. AMK 77-6. The requirement necessitates that these modifications be completed within 300 hours of time in service following 30 September 1977, underscoring the importance of timely adherence to the directive for ensuring aircraft safety and airworthiness. This regulation is a component of the broader framework established by the Civil Aviation Safety Authority, enforcing stringent safety standards across the Australian aviation sector. The scope of this regulation is limited to the specified models and serial numbers of the Gates Learjet 35 and 36 series, thereby ensuring that only relevant aircraft are subject to this directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, includes Airworthiness Directives that govern the operational safety of aircraft. One such directive, AD/LEARJET 35/6, pertains to the Gates Learjet 35 and 36 series aeroplanes and mandates a specific modification to the wing to fuselage attachment. According to section 105 of the regulations, this directive applies to all Gates Learjet model 35 aircraft with serial numbers (S/Nos.) ranging from 35-001 to 35-110, excluding 35-107, and all model 36 aircraft with S/Nos. from 36-001 to 36-031. The directive requires that the wing to fuselage attachment be modified to comply with Gates Learjet Kit No. AMK 77-6. The modification outlined in the AD/LEARJET 35/6 directive must be completed within 300 hours of time in service after 30 September 1977. This timeframe is critical to ensure that the aircraft maintain their airworthiness and meet the safety standards set by the Civil Aviation Safety Authority (CASA). The directive's applicability is stringent, leaving no room for deviation among the specified aircraft models and serial numbers. Compliance with this directive is mandatory for operators of the specified Gates Learjet models. Failure to adhere to the requirements could result in the aircraft being deemed unairworthy, which could lead to grounding and potential enforcement actions. Operators must ensure that the modifications are performed by authorised personnel and that the aircraft are inspected to confirm compliance with the specified standards. The regulation imposes a clear obligation on aircraft operators to maintain the airworthiness of their aircraft through timely and accurate compliance with CASA directives. In the event of non-compliance with the AD/LEARJET 35/6 directive, there are potential legal and financial consequences. The Civil Aviation Regulations 1998 establish various offences and penalties for breaches of airworthiness directives. For instance, operating an aircraft that does not comply with applicable airworthiness directives can lead to civil penalties, including fines and possible suspension or revocation of the aircraft's certificate of airworthiness. Additionally, there may be criminal consequences for individuals or corporations found guilty of violating these regulations, including imprisonment and significant fines. The specific penalties are outlined in the broader civil aviation legislation and can vary based on the severity and intent of the breach.
