AD/CESSNA 180/22 - Tail Wheel Steering Bellcrank

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, establish a comprehensive framework for ensuring the safety and regulation of civil aviation within Australia. This legislation aims to address the need for a coordinated and effective approach to aviation safety, including the issuance of airworthiness directives that mandate specific maintenance and inspection requirements for certain aircraft types. One such directive, AD/CESSNA 180/22, targets the Cessna 180, 182, and Wren 460 series aeroplanes, specifically addressing the inspection and replacement of tailwheel steering bellcranks in agricultural models. This directive was introduced to mitigate potential safety risks associated with the degradation of the tailwheel steering bellcranks, ensuring that these components are maintained to the highest safety standards. The policy objective of this particular airworthiness directive is to prevent potential failures in the tailwheel steering system, which could lead to compromised control of the aircraft during flight. By mandating regular inspections and the replacement of defective bellcranks, the directive aims to maintain the integrity and safety of these aircraft, thereby protecting both the crew and passengers. The directive applies to all models in the agricultural category and requires that inspections be conducted at intervals not exceeding 100 hours of time in service.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Airworthiness Directives that govern the safety standards for aircraft operating within Australia. This particular legislative instrument, AD/CESSNA 180/22, applies to all models of Cessna 180, 182, and Wren 460 Series aeroplanes in the agricultural category. It mandates that these aircraft undergo an inspection of the tailwheel steering bellcranks, identified by part number 0712309-1, located in the rear fuselage to check for elongated pin holes. Any defective bellcranks must be replaced to ensure compliance with the regulations. This inspection is required at intervals not exceeding 100 hours of time in service. The scope of this directive is nationally applicable under the Commonwealth of Australia, enforced by the Civil Aviation Safety Authority. The regulations do not specify any exclusions, exemptions, or thresholds beyond the stipulated intervals for inspection and replacement.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Cessna 180, 182, and Wren 460 Series Aeroplanes, includes AD/CESSNA 180/22 which pertains to the tail wheel steering bellcrank (section 11/67). This directive applies to all models within the agricultural category (section 11/67). The primary requirement outlined in this directive is the inspection of the tailwheel steering bellcranks, specifically those with part number 0712309-1, located in the rear fuselage (section 11/67). The inspection must focus on checking for elongated pin holes. Any bellcranks found to be defective must be replaced (section 11/67). The obligations imposed by this directive require operators of the specified Cessna models to ensure that inspections are conducted at intervals not exceeding 100 hours of time in service (section 11/67). Operators must be vigilant in identifying any signs of elongated pin holes in the tailwheel steering bellcranks and take immediate corrective action by replacing any defective components. This ensures the continued airworthiness and safety of the aircraft in the agricultural category, which often operates in environments that may exacerbate wear and tear on aircraft components. Failure to comply with the requirements set forth in AD/CESSNA 180/22 can result in severe consequences. Firstly, non-compliance may lead to the aircraft being deemed unairworthy, which can prevent it from being operated until the necessary repairs are made. Furthermore, there can be civil penalties imposed for violations of these regulations. The maximum penalty for contravening a Civil Aviation Order can include fines up to $16,500 for individuals and $82,500 for corporations, as well as potential criminal charges. These consequences underscore the importance of adhering to the directive to maintain safety standards in civil aviation.
