AD/CESSNA 188/17 - Alternator Earth Lead

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, are a comprehensive set of rules and standards designed to ensure the safety and efficiency of civil aviation within Australian airspace. One of the specific enactments under this overarching regulation is the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes AD/CESSNA 188/17 concerning the Cessna 188 (Agwagon) Series Aeroplanes. This directive was introduced to address a specific safety concern identified with the aircraft's alternator earth lead, ensuring it is correctly installed, in good condition, and securely attached. The policy objective behind this directive is to maintain the highest safety standards in civil aviation by mandating regular inspections and compliance with critical maintenance tasks within a specified timeframe, in this case, within 100 hours of time in service after 29 February 1972.

Scope and Application

The Civil Aviation Safety Authority's Schedule of Airworthiness Directives, specifically AD/CESSNA 188/17, pertains to the Cessna 188 (Agwagon) Series Aeroplanes, applying to all models within this series. This regulation is mandated by the Civil Aviation Regulations 1998, which governs civil aviation in Australia and ensures that aircraft meet specific safety standards. The directive requires operators and owners of these aircraft to verify that the alternator earth lead is installed, in good condition, and securely attached, with compliance necessary within 100 hours of time in service after 29 February 1972. This legislative instrument is applicable throughout the Commonwealth of Australia and extends its reach to all entities operating Cessna 188 series aircraft within the country. The directive does not specify any exclusions or exemptions but mandates compliance as a critical safety measure, with potential extensions or restrictions to application potentially provided through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998 (CARs) are found in Part 39, which deals with airworthiness directives. Specifically, AD/CESSNA 188/17 concerns the Cessna 188 (Agwagon) series aeroplanes and mandates that the alternator earth lead must be fitted, in good condition, and securely attached (CARs 39-105). The requirement is to ensure the aircraft complies with these standards within 100 hours of time in service after 29 February 1972. This directive is crucial for maintaining the safe operation of the aircraft and preventing electrical failures that could compromise flight safety. The obligations imposed by AD/CESSNA 188/17 on the parties governed by this legislation, primarily aircraft operators and maintenance personnel, include the inspection and maintenance of the alternator earth lead. Operators must ensure that the specified maintenance checks are carried out, and maintenance personnel are responsible for verifying that the alternator earth lead is indeed installed, in good working order, and securely attached. These tasks must be completed within the prescribed timeframe to comply with the regulation. Failure to comply with AD/CESSNA 188/17 can lead to serious consequences. The legislation does not explicitly state penalties but implies that non-compliance could result in the aircraft being deemed unairworthy, which could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, legal action, or other regulatory penalties as deemed appropriate by CASA. Additionally, failure to adhere to these directives can potentially result in accidents or incidents, which could lead to criminal charges if negligence or willful disregard of safety regulations is established.
