AD/CA-6/1 - Tail Wheel Stabiliser Locknut - Inspection

Overview

The Civil Aviation Safety Regulations 1998 (Cth), enacted by the Commonwealth of Australia, address the need for stringent safety standards in the aviation industry. This legislative instrument, specifically under Part 39 - 105, establishes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which aims to ensure the airworthiness of aircraft through detailed safety regulations. This includes, for example, AD/CA-6/1 concerning the inspection of the tailwheel bungee stabiliser locknut on C.A.C CA-6 (Wackett Trainer) Series Aeroplanes, underscoring the policy objective to mitigate risks and enhance flight safety by mandating regular inspections at intervals not exceeding 25 hours of service time. This regulation is designed to maintain the structural integrity and operational safety of the aircraft, ensuring compliance with CASA standards.

Scope and Application

The Civil Aviation Safety Authority’s regulation, part of the Civil Aviation Regulations 1998, specifically mandates that all Wackett Trainer Series Aeroplanes must adhere to the requirements outlined in AD/CA-6/1 concerning the tailwheel bungee stabiliser locknut. This regulation applies universally to all models within the Wackett Trainer series and necessitates the inspection of the tightness of the locknut (Part No. 06-34041) at intervals not exceeding 25 hours of time in service. The regulatory oversight ensures that all civil aviation operations involving these aircraft models maintain stringent safety standards, and the requirement is applicable across the Commonwealth of Australia, enforcing uniformity in compliance and safety protocols. The regulation does not specify any exclusions or exemptions, indicating that all operators must adhere to the prescribed inspection intervals without exception. The regulation’s scope is thus clearly defined, with no modifications or extensions to its application through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, details the requirements for the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD). In this context, AD/CA-6/1 pertains to the Wackett Trainer series aeroplanes, focusing on the inspection of the tailwheel bungee stabiliser locknut (Part No. 06-34041) (Section 105). This directive applies to all models within the specified series (Section 105(1)). The primary requirement of this regulation is to ensure that the tailwheel bungee stabiliser locknut is checked for tightness at intervals not exceeding 25 hours of time in service (Section 105(2)). This periodic inspection is crucial for maintaining the airworthiness and safety of the aircraft. The directive aims to prevent any potential failure of the tailwheel bungee stabiliser locknut, which could lead to significant safety risks during flight operations. Entities governed by these regulations, including aircraft owners, operators, and maintenance personnel, must adhere to the stipulated inspection intervals (Section 105(3)). This means conducting the required checks on the tailwheel bungee stabiliser locknut every 25 hours or less to ensure compliance with safety standards. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, potentially leading to grounding until the issue is resolved. Violations of the Civil Aviation Regulations 1998 can result in serious consequences. The regulations do not explicitly state the penalties for non-compliance with AD/CA-6/1 in this excerpt, but generally, breaches of airworthiness directives can lead to substantial civil and criminal penalties. Civil penalties may include fines, and in severe cases, criminal charges could be filed against individuals or entities responsible for the non-compliance. These legal actions are intended to enforce adherence to safety standards and protect public safety within the aviation industry.
