AD/PA-32/53 - Engine Control Rod End Bearings - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serves to regulate all aspects of civil aviation within the country, ensuring safety and efficiency in air travel. One specific legislative instrument under this act is F2006B05850, which pertains to the Piper PA-32 (Cherokee Six) series aeroplanes. This legislation was introduced to address safety concerns associated with engine control rod end bearings, specifically those attached to the mixture, throttle, and propeller governor control cables. The policy objective behind this directive is to ensure that these components are maintained in a safe and reliable condition, thereby preventing potential mechanical failures that could compromise flight safety. Compliance with these directives is mandatory for specified models and serial numbers, requiring inspections and necessary replacements within a stipulated timeframe to uphold the stringent safety standards set by the Civil Aviation Safety Authority. The Civil Aviation (Airworthiness) Regulations 1998, as amended, provide a comprehensive framework for maintaining airworthiness standards across the aviation industry in Australia. Legislative instrument F2006B05850 is a critical component of this regulatory structure, focusing on the Piper PA-32 series aeroplanes. This directive mandates inspections and, where necessary, the replacement of engine control rod end bearings to prevent potential mechanical failures. By enforcing these measures, the Civil Aviation Safety Authority aims to mitigate risks associated with the specified models, ensuring that they remain airworthy and safe for operation. The requirement for compliance within a specific timeframe underscores the urgency and importance of addressing these safety issues to protect both the aircraft and its occupants.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses the maintenance and inspection requirements for certain models of the Piper PA-32 (Cherokee Six) series aeroplanes. This legislation applies to aeroplanes of the PA32-260, PA32-300, and PA32R-300 series with specific serial number ranges. The directive mandates that these aircraft must undergo an inspection of the rod end bearing assemblies attached to the mixture, throttle, and propeller governor control cables, with a specific focus on identifying and replacing any rod end bearings that do not correspond to the approved types illustrated in the directive. Compliance with these requirements is necessary within 25 hours of time in service after the directive was issued on 22 November 1977. This regulation applies across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority, ensuring that the specified aircraft models meet the necessary safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, include provisions concerning the airworthiness directives issued by the Civil Aviation Safety Authority (CASA). One such directive, AD/PA-32/53, pertains to the Piper PA-32 (Cherokee Six) series aeroplanes and requires inspections and replacements of engine control rod end bearings. This directive applies to specific models and serial numbers of the PA32-260, PA32-300, and PA32R-300 series. The directive mandates that the rod end bearing assemblies attached to the mixture, throttle, and propeller governor control cables must be inspected against the provided illustration. If any rod end bearing matches the description in the illustration as number one (1), it must be replaced with a bearing corresponding to number two (2) or number three (3) of the same illustration. Compliance with this directive is required within 25 hours of time in service after 22 November 1977. The obligations imposed by this airworthiness directive are clear and specific. Operators and owners of the affected aircraft must ensure that the required inspections are conducted and that any necessary replacements of the rod end bearings are completed in accordance with the directive. This involves having trained personnel perform the inspection and replacement tasks and ensuring that the correct parts are used as specified. Failure to comply with these obligations could lead to significant safety risks, as the directive aims to address potential issues with the rod end bearings that could compromise the safe operation of the aircraft. Violations of airworthiness directives, such as AD/PA-32/53, can have serious consequences. While the specific penalties for non-compliance are not detailed in the provided text, generally, under the Civil Aviation Act 1988, non-compliance with CASA regulations can result in civil penalties. The maximum penalty for a corporation can be up to $210,000, and for an individual, it can be up to $42,000. In more severe cases, criminal penalties may also apply, potentially leading to imprisonment. CASA has the authority to issue enforcement notices, suspend or revoke aircraft certificates, and take legal action against those who fail to comply with the regulations. These consequences underscore the importance of adhering to the specified airworthiness directives to maintain the safety standards required in civil aviation.
