AD/CESSNA 177/28 - Fuel Cap Alignment Placard

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as a comprehensive framework governing civil aviation safety, with specific attention to aircraft airworthiness and maintenance. One particular aspect of this legislative framework is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which includes AD/CESSNA 177/28 concerning the alignment of fuel cap placards on certain Cessna 177 Series Aeroplanes. This directive was introduced to address the critical issue of ensuring the correct alignment of fuel caps on specified models to maintain efficient operation of the fuel tank secondary vent system. The policy objective behind this directive is to enhance aviation safety by mandating compliance with specific maintenance actions within a defined timeframe, thereby reducing the risk of operational failures and potential accidents. This legislative instrument underscores the importance of precise adherence to manufacturer service instructions to safeguard the integrity and safety of aircraft operations. By stipulating compliance within 100 hours of time in service following the directive's issuance date, the regulation ensures that operators of affected aircraft promptly address any discrepancies in fuel cap alignment, thereby mitigating risks associated with improper vent system function. The enactment of such directives by the Civil Aviation Safety Authority reflects a commitment to stringent safety standards and proactive risk management within the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to the specified serial numbers of the Cessna 177 Series Aeroplanes, including Models 177, 177RG, and F177RG, with the serial numbers falling within the specified ranges. These regulations mandate adherence to Airworthiness Directive AD/CESSNA 177/28, which requires the alignment placard for the fuel cap to be correctly installed and maintained. This regulation ensures that the flush fitting type fuel caps are correctly aligned, which is critical for the efficient operation of the fuel tank secondary vent system. Compliance must be achieved within 100 hours of the aircraft being in service after 30 September 1980, as outlined in Cessna Service Information Letter SE 80-59. The scope of this regulation is limited to the specified aircraft models and serial numbers, and it does not extend to other aircraft types or models outside this scope. The requirement applies across the Commonwealth of Australia, and no specific exclusions or exemptions are mentioned within the provided text, although broader regulatory frameworks may provide for such instances.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998, Part 39 - 105, specifically AD/CESSNA 177/28, mandate that certain Cessna 177 series aeroplanes must have a fuel cap alignment placard installed. This applies to Model 177 aircraft with serial numbers (S/Nos.) ranging from 661 to 17702752, Model 177RG with S/Nos. 177RG0001 to 177RG0177, and Model F177RG with S/Nos. F177RG0001 to F177RG0177. According to section 9/80, the alignment of the flush fitting type fuel caps is crucial for the efficient operation of the fuel tank secondary vent system. Compliance with the Airworthiness Directive (AD) is mandatory and must be achieved within 100 hours of time in service after 30 September 1980. The obligations imposed by this regulation are clear and specific. Operators of the affected Cessna 177 series aircraft must ensure that the fuel cap alignment placard is installed as per the requirements outlined in Cessna Service Information Letter (SIL) No. SE 80-59. This includes verifying that the placard is correctly fitted and that the fuel caps are properly aligned. The onus is on the aircraft owner or operator to maintain the aircraft in a safe and airworthy condition, which includes adhering to the AD. Failure to comply with these obligations could result in the aircraft being deemed unairworthy. In terms of consequences, non-compliance with the AD/CESSNA 177/28 directive can lead to serious legal and operational repercussions. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions against operators who fail to adhere to airworthiness directives. Penalties for non-compliance can include fines, enforcement notices, and potentially more severe sanctions such as suspension or revocation of the aircraft's certificate of airworthiness. In extreme cases, where non-compliance is found to have contributed to an aviation incident or accident, criminal charges may be pursued against the responsible parties, leading to imprisonment and additional fines. It is therefore imperative for all affected parties to strictly adhere to the requirements set forth in the AD.
