AD/CESSNA 500/3 - Elevator Torque Tube Assembly - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation within Australia. One of the key issues these regulations aim to address is the maintenance and safety of specific aircraft models, ensuring they comply with international standards. The legislative instrument F2006B08403, specifically pertaining to the Cessna 500 (Citation) Series Aeroplanes, targets the inspection and replacement of the elevator torque tube assembly. This measure is crucial for ensuring the continued airworthiness of these aircraft, thereby maintaining high safety standards for all involved in civil aviation. The enactment of this regulation by the Commonwealth of Australia demonstrates a commitment to addressing specific safety concerns related to particular aircraft models. The policy objective is to proactively manage and mitigate risks associated with the elevator torque tube assembly in Cessna 500 series aeroplanes. By requiring inspections and necessary replacements before the issue of a certificate of airworthiness, CASA reinforces its role in safeguarding aviation safety. This targeted approach is intended to prevent potential failures and ensure that all aircraft meet stringent safety requirements, thereby protecting both operators and passengers.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/CESSNA 500/3, applies to all Cessna 500 (Citation) series aeroplanes with serial numbers ranging from 500-0001 to 500-0072. This regulation mandates the inspection and replacement of the elevator torque tube assembly and is enforceable under the Civil Aviation Regulations 1998, which are applicable throughout the Commonwealth of Australia. The directive must be adhered to before the issuance of a certificate of airworthiness, as stipulated in document Cessna SB 55-2. The scope of this directive is narrowly focused on the specified model and serial numbers of the aircraft, and it is an integral part of ensuring that these aircraft meet the necessary safety standards set forth by the Civil Aviation Safety Authority. The regulation does not explicitly mention any exclusions, exemptions, or thresholds, and its application may be extended or clarified through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, include a Schedule of Airworthiness Directives (AD) for specific aircraft types. In this case, AD/CESSNA 500/3 pertains to Cessna 500 (Citation) Series Aeroplanes with serial numbers ranging from 500-0001 to 500-0072 (subsection 6/73). This directive mandates inspection and replacement of the elevator torque tube assembly. The primary requirement is that any compliance with this directive must occur before the issue of a certificate of airworthiness (subsection 6/73). These regulations impose clear obligations on aircraft owners, operators, and maintenance personnel. The primary obligation is to ensure that the elevator torque tube assembly of the specified Cessna 500 aircraft is inspected and, if necessary, replaced according to the procedures outlined in Cessna Service Bulletin 55-2 (subsection 6/73). This requirement is essential to maintain the safety and airworthiness of these aircraft, ensuring they meet the stringent safety standards set by the Civil Aviation Safety Authority (CASA). Failure to comply with the airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to civil penalties. The maximum penalty for a corporation can be up to $1,650,000, and for an individual, it can be up to $330,000 (subsection 319). Additionally, CASA has the authority to suspend or cancel the aircraft’s certificate of airworthiness if it is found that the required inspections and repairs have not been performed. This suspension or cancellation can result in the aircraft being grounded, preventing it from operating until the necessary compliance is achieved.
