AD/BEECH 23/6 - Rudder Pedal Position Gear

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. The regulations are designed to address issues related to the airworthiness of aircraft and to ensure that all civil aviation activities are conducted in a manner that protects the public and enhances the safety of aviation operations. The legislative instrument in question, F2006B03762, specifically pertains to Beechcraft 19, 23, and 24 Series aeroplanes, outlining an Airworthiness Directive (AD) to address a critical safety issue with the rudder pedal position gear. This directive, AD/BEECH 23/6, requires the replacement of all nylon gears P/N 169-524039-1 with aluminium gears P/N 169-524039-3 on applicable models, aiming to enhance the structural integrity and safety of the rudder system, thereby mitigating potential risks associated with the use of nylon gears in this critical component.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, apply to all Beechcraft 19, 23, and 24 series aeroplanes that are fitted with rudder pedal position gear part number 169-524039-1. This regulation mandates the replacement of all existing nylon gears with aluminium gears part number 169-524039-3. Compliance with this directive is required for aeroplanes manufactured before 1 September 1971. The regulation is issued by the Civil Aviation Safety Authority and applies across the Commonwealth of Australia, ensuring a uniform standard of airworthiness for these aircraft. The scope of this legislation extends to all operators and owners of the specified Beechcraft models within the Australian jurisdiction, thereby ensuring the safety and reliability of these aircraft in the national airspace. There are no stated exclusions or exemptions in this directive, and its application is enforced through the subordinate instruments of the Civil Aviation Regulations.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, includes Airworthiness Directives (AD) that mandate certain safety requirements for aircraft. One such AD is AD/BEECH 23/6 concerning Beechcraft 19, 23, and 24 series aeroplanes. The directive (AD/BEECH 23/6) focuses on the rudder pedal position gear and mandates the replacement of nylon gears with aluminium gears in specific models (Section 11/64). This directive applies to all models fitted with gear P/N 169-524039-1. The requirement is to replace these nylon gears with aluminium gears P/N 169-524039-3. The AD imposes obligations on aircraft owners and operators to ensure that the specified rudder pedal position gear is replaced in accordance with the directive. The requirement must be fulfilled before 1 September 1971 to ensure compliance with safety standards set by the Civil Aviation Safety Authority (CASA). This obligation includes conducting a thorough inspection to identify the relevant nylon gears and then replacing them with the specified aluminium gears. Failure to comply with this AD could lead to serious safety implications, potentially compromising the aircraft's control and stability. Although the Civil Aviation Regulations do not explicitly state offences, penalties, or consequences for non-compliance with specific ADs, CASA has the authority to enforce compliance through various means. Non-compliance could result in the aircraft being grounded, or the operator facing fines, enforcement actions, or even criminal charges if the non-compliance leads to an accident or endangers flight safety. The potential penalties can be severe, given the critical nature of the rudder pedal position gear to flight safety.
