COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 210 Series Aeroplanes
AD/CESSNA 210/55
Amdt 1
Bladder Type Fuel Cells - Inspection and Modification
6/85
Applicability: All models with S/Nos as listed in Cessna SIL SE 84-4.
Requirement: Inspect fuel cells in accordance with Cessna SIL SE 84-4 and record the result in the aircraft log book. Where cells exhibit wrinkles or folds, purge fuel system of moisture or other contaminants.
Note: Additional information on fuel system purging is contained in Cessna Owner Advisory SE 82-36A.
Compliance: 1. AIRCRAFT NOT MODIFIED IN ACCORDANCE WITH CESSNA SIL SE 84-9,Rev 1.
Initially, before further flight after 31 August 1984 for cells currently fitted, and at installation of any cell after 31 August 1984. Thereafter, for cells that exhibited signs of unacceptable wrinkles or folds at initial inspection, repeat the system purging procedures at each issue of a new Maintenance Release.
2. AIRCRAFT MODIFIED IN ACCORDANCE WITH CESSNA SIL SE 84-9, Rev 1.
When future cell replacement is required, carry out further instructions required by Attachment No. 1 of | Cessna SIL SE 84-9 Rev 1.
3. For aircraft that have complied with the previous issue of this Directive, the log book statement requirement shall be made before the issue of the next Maintenance Release after 30 June 1985.
Background: This Directive promulgates the latest revision to Cessna SIL SE 84-9 containing “Helpful Hints” useful to maintenance personnel. The fuel cap testing requirement has been removed and now becomes the subject of a separate Directive. Editorial changes and a requirement for log book statements are also included.
Overview
The Civil Aviation Regulations 1998, specifically within Part 39, addresses the safety and operational standards for civil aviation in Australia. One of the key legislative instruments under this Act is the Airworthiness Directives (AD) series, which aims to ensure the safety and airworthiness of aircraft. The AD/CESSNA 210/55 Amendment 1, enacted to address safety concerns related to bladder-type fuel cells in Cessna 210 Series aeroplanes, was introduced to mitigate the risks associated with wrinkles or folds in these fuel cells that could potentially lead to contamination of the fuel system. This amendment, implemented by the Civil Aviation Safety Authority (CASA), underscores the policy objective of maintaining stringent safety standards to prevent operational failures and enhance the safety of air travel. The directive requires inspections and necessary modifications to ensure the fuel cells are free from defects, with specific compliance protocols outlined for both unmodified and modified aircraft, ultimately aiming to safeguard the integrity of the fuel system and the safety of flights.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the application of airworthiness directives through the Civil Aviation Safety Authority, with the schedule focusing on the Cessna 210 Series Aeroplanes. This regulation mandates that all models of the Cessna 210 Series with specific serial numbers as outlined in Cessna SIL SE 84-4 must comply with the Airworthiness Directive AD/CESSNA 210/55 Amendment 1. This directive requires the inspection of bladder-type fuel cells in accordance with Cessna SIL SE 84-4 and mandates recording the inspection results in the aircraft log book. If the cells exhibit wrinkles or folds, the fuel system must be purged of moisture or other contaminants. For aircraft that have not been modified according to Cessna SIL SE 84-9, Rev 1, the inspection and subsequent system purging must be performed before further flight after 31 August 1984 for currently fitted cells, and at the installation of any new cell after this date. Aircraft that have complied with previous directives must record the log book statement before the issue of the next Maintenance Release after 30 June 1985. For modified aircraft, further instructions are to be followed as detailed in Attachment No. 1 of Cessna SIL SE 84-9, Rev 1.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39, includes detailed directives concerning the airworthiness of aircraft. Section 105 of the regulations provides specific requirements for the inspection and modification of bladder type fuel cells in Cessna 210 series aeroplanes, outlined in AD/CESSNA 210/55 Amendment 1. The regulation mandates that all models with serial numbers listed in Cessna SIL SE 84-4 must undergo inspection in accordance with the specified procedures. This inspection includes checking for wrinkles or folds in the fuel cells and requires the aircraft log book to record the results (Section 105). If wrinkles or folds are identified, the fuel system must be purged of moisture or contaminants, with additional details provided in Cessna Owner Advisory SE 82-36A.
These regulations impose several obligations on aircraft operators and maintenance personnel. For aircraft that have not been modified according to Cessna SIL SE 84-9, Revision 1, inspections must occur before further flight after 31 August 1984 for existing fuel cells and at the installation of any new cell post-date. For aircraft modified in accordance with the specified standards, any future cell replacement must follow additional instructions detailed in Attachment No. 1 of Cessna SIL SE 84-9, Revision 1. Furthermore, aircraft that have already complied with earlier versions of this directive must record the compliance in their log book before the next Maintenance Release after 30 June 1985.
Failure to comply with these provisions can result in significant consequences. The regulations do not explicitly state penalties, but non-compliance with airworthiness directives can lead to serious safety issues, potentially resulting in the grounding of the aircraft. Operators found to be in breach of these safety directives may face scrutiny and enforcement actions from the Civil Aviation Safety Authority (CASA). Such actions can include fines, legal action, or other regulatory sanctions, depending on the severity of the non-compliance and its impact on flight safety.
