COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Cessna 190 and 195 Series Aeroplanes
AD/CESSNA 190/8 Magnesium Inboard Aileron Hinge Brackets 1/2005
Applicability: All Model 190, 195, 195A, and 195B aircraft; equipped with at least one part number 0322709 or 0322709-1 inboard aileron hinge bracket.
Requirement: 1. Inspect each part number 0322709 or 0322709-1 inboard aileron hinge bracket or any other bracket made from magnesium for cracks or corrosion, in accordance with Cessna Single Engine Service Bulletin SEB04-1, dated 26 April 2004.
2. Replace any cracked or corroded inboard aileron hinge bracket after any inspection where any cracked or corroded bracket is found. Use the procedures included with the FAA-approved replacement and the FAA-approved maintenance manual. This could include Cessna parts, supplemental type certificate (STC) parts, or parts manufacturer approval (PMA) parts, etc.
Note: FAA AD 2004-21-08 Amdt 39-13828 refers.
Compliance: 1. Unless the initial inspection is already accomplished, within 100 hours time in service after 20 January 2005. Inspect thereafter at intervals not to exceed 100 hours time in service until each affected bracket is replaced with an FAA- approved bracket that is made from aluminium, as specified in the service information.
2. Before further flight.
This Airworthiness Directive becomes effective on 20 January 2005.
Background: The FAA received several reports of cracks and corrosion found on the magnesium inboard aileron hinge brackets. Magnesium is known to be susceptible to corrosion. Such damage could result in the brackets cracking across the bearing boss and could lead to the aileron separating from the aircraft, with consequent reduced or loss of control of the aircraft.

The above AD is notified in the Commonwealth of Australia Gazette on 22 December 2004.

Overview
The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to provide a comprehensive regulatory framework for ensuring the safety of civil aviation in Australia. This legislation addresses the need for consistent and effective standards across the aviation industry, aiming to prevent accidents and incidents by ensuring all aircraft and related products meet stringent safety requirements. The CASR 1998 empowers the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (ADs) as a critical tool to mandate corrective actions when safety issues are identified. An example of this is AD/CESSNA 190/8, issued in 2005, which was aimed at addressing the identified risk of cracks and corrosion in magnesium inboard aileron hinge brackets of certain Cessna aircraft models. The directive was introduced to mitigate the risk of potential loss of control due to bracket failure, thereby enhancing flight safety. The AD was issued under the authority of the Civil Aviation Safety Authority, reflecting the policy objective of maintaining high safety standards in the aviation sector.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Safety Authority, issue specific Airworthiness Directives (AD) to address identified safety issues with particular aircraft or aeronautical products. In this instance, AD/CESSNA 190/8 concerns all Model 190, 195, 195A, and 195B aircraft equipped with certain inboard aileron hinge brackets. The directive requires an inspection of the specified brackets for cracks or corrosion and mandates their replacement if any damage is found. Compliance with this AD must be achieved within 100 hours of the directive's effective date, and inspections must continue at intervals not exceeding 100 hours until all affected brackets are replaced with FAA-approved aluminium brackets. The AD extends to the Commonwealth of Australia, as administered by the Civil Aviation Safety Authority, and applies to all relevant aircraft operating within Australian jurisdiction. The AD was issued under subregulation 39.1 (1) of CASR 1998 and was gazetted on 22 December 2004, ensuring its application across the relevant industry.
Key Provisions
The Civil Aviation Safety Regulations 1998 (CASR) contain various provisions for ensuring the safety of aviation activities in Australia. Under Part 39, specifically section 105, an Airworthiness Directive (AD) is issued by the Civil Aviation Safety Authority (CASA) delegate, who considers it necessary to address an unsafe condition in certain aircraft. This particular AD, AD/CESSNA 190/8, pertains to all Model 190, 195, 195A, and 195B aircraft equipped with specific inboard aileron hinge brackets made from magnesium (sections 1 and 2). The AD mandates the inspection of these brackets for cracks or corrosion, and if any are found, they must be replaced with FAA-approved brackets made from aluminium (section 3).
The AD imposes specific obligations on the operators and owners of the affected aircraft. They must conduct the required inspections and replacements within stipulated timeframes. The initial inspection must be completed within 100 hours of time in service after 20 January 2005, and subsequent inspections must be conducted at intervals not exceeding 100 hours until the replacement is complete (section 4). The replacement must be carried out before any further flight, ensuring that the aircraft remains airworthy at all times (section 5). This directive underscores the importance of adhering to specific procedures, including those outlined in the Cessna Single Engine Service Bulletin SEB04-1 and FAA-approved maintenance manuals, to maintain the structural integrity of the aircraft.
Failure to comply with the AD may result in serious safety implications, given the potential for the brackets to crack and lead to loss of control over the aircraft. The consequences of non-compliance could be severe, potentially resulting in accidents that could endanger lives. The Civil Aviation Safety Regulations do not explicitly detail the penalties for non-compliance with ADs, but non-compliance with aviation safety regulations can generally lead to civil or criminal penalties under the Civil Aviation Act 1988. These penalties may include fines and, in more severe cases, imprisonment. The exact penalties would depend on the specific circumstances and the discretion of the court.
