AD/CESSNA 180/69 Amdt 1 - Bladder Type Fuel Cells

Overview

The Civil Aviation Regulations 1998, amended in 2006, were enacted to ensure the safety of civil aviation within Australia, providing comprehensive regulatory oversight of all aspects of civil aviation operations. This legislation, overseen by the Parliament of Australia, addresses the need for a robust framework to maintain airworthiness standards, particularly in the context of aircraft maintenance and safety directives. One such directive, AD/CESSNA 180/69 Amendment 1, pertains specifically to Cessna 180, 182, and Wren 460 Series Aeroplanes, focusing on bladder type fuel cells. The objective of this directive is to mandate inspections and necessary actions to ensure the integrity of the fuel cells, thereby mitigating risks associated with fuel contamination and ensuring continued compliance with airworthiness standards. The policy objective aligns with the overarching goal of enhancing aviation safety by addressing specific technical issues within the aircraft maintenance protocol.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 105, mandates Airworthiness Directives for certain aircraft models, including the Cessna 180, 182, and Wren 460 series aeroplanes. This legislation applies to all aircraft with serial numbers as listed in the Cessna SIL SE 84-4 document, and its geographic reach encompasses the entire Commonwealth of Australia. The primary requirement of this directive is the inspection of bladder type fuel cells in accordance with Cessna SIL SE 84-4, with the results to be recorded in the aircraft logbook. If any cells show signs of wrinkles or folds, the fuel system must be purged of moisture or contaminants. For aircraft not modified in line with Cessna SIL SE 84-9, Rev 1, initial inspections must be conducted before further flight after August 31, 1984, and at the installation of any new cell post this date. For aircraft that have been modified as per Cessna SIL SE 84-9, Rev 1, further instructions for cell replacement are outlined in Attachment No. 1 of Cessna SIL SE 84-9, Rev 1. Aircraft that have already complied with earlier versions of this directive must include a logbook statement before the issuance of the next Maintenance Release after June 30, 1985. This directive also removes the fuel cap testing requirement, which is now subject to a separate directive, and includes editorial changes and a requirement for logbook statements.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, and the accompanying schedule of Airworthiness Directives, include detailed provisions for the maintenance and safety of various aircraft models. For Cessna 180, 182, and Wren 460 Series Aeroplanes, the key provision under AD/CESSNA 180/69 Amendment 1 pertains to bladder type fuel cells (Section 6/85). This section mandates that all affected models with specific serial numbers must undergo an inspection of their fuel cells as outlined in Cessna SIL SE 84-4. The inspection results must be recorded in the aircraft log book. If any cells exhibit wrinkles or folds, the fuel system must be purged of moisture or other contaminants. Entities governed by these regulations must ensure that the inspections and necessary actions are carried out as specified. For aircraft not modified according to Cessna SIL SE 84-9, Revision 1, the inspection must occur before further flight after 31 August 1984 for existing cells and at the time of any new cell installation post-31 August 1984. For cells that show unacceptable wrinkles or folds during the initial inspection, the fuel system purging procedures must be repeated each time a new Maintenance Release is issued. For aircraft modified according to Cessna SIL SE 84-9, Revision 1, the instructions provided in Attachment No. 1 of Cessna SIL SE 84-9, Revision 1, must be followed when future cell replacements are required. Furthermore, for aircraft that have already complied with the previous version of this directive, the log book statement requirement must be fulfilled before the next Maintenance Release after 30 June 1985. Failure to comply with these regulations can result in significant legal consequences. The breach of these Airworthiness Directives can lead to civil or criminal penalties, depending on the severity and intent of the violation. The maximum penalties for non-compliance with Civil Aviation Regulations can include substantial fines and, in severe cases, imprisonment. The exact penalties may vary based on the specific breach and the discretion of the court, but they underscore the importance of adhering to these safety requirements to ensure the continued airworthiness and safety of the aircraft in question.
