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 revokes Airworth iness Directive (AD) AD/R22/24 and issues the following 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.
Robinson R22 Series Helicopters
AD/R22/24
Amdt 1
Lower Actuator Bearing Mounting Brackets 6/2003
Applicability: All R22 series helicopters.
Requirement: Action in accordance with the R22 Maintenance Manual, Rev 21, June 2000, Page 2.24, Section 2.410, Item # 8.
Note: This requirement was formerly contained in SB-44, which has now been cancelled.
Compliance: As specified in the R22 Maintenance Manual.
This Amendment becomes effective on 12 June 2003.
Background: This AD was raised to mandate the incorporation of SB-44 after loose rivets were found in an R22 helicopter, allowing the A181 bearing to misalign. This eventually led to vee belt drive failure.
This amendment changes the requirement section to refer to the Maintenance Manual instead of SB-44 (R22 model only), because SB-44 has been cancelled. There is no change to the compliance time.
The original issue of the AD became effective on the 31 May 1985.
David Villiers
Delegate of the Civil Aviation Safety Authority 22 April 2003
The above AD is notified in the Commonwealth of Australia Gazette on 21 May 2003.

Overview
The Civil Aviation Safety Regulations 1998 (CASR) were enacted to ensure the safety of civil aviation in Australia, addressing the need for comprehensive safety regulations to protect the public and maintain high standards within the aviation industry. The 1998 Regulations were introduced to modernise and consolidate existing safety legislation, providing a clear and structured framework for the Civil Aviation Safety Authority (CASA) to oversee and enforce safety measures across the aviation sector. The policy objective of the CASR is to mitigate risks associated with civil aviation, ensuring the safety and efficiency of air travel through stringent regulatory standards. This particular legislative instrument, F2006B06430, focuses on Airworthiness Directives, specifically addressing the safety concerns related to the Robinson R22 Series Helicopters, and was issued by the delegate of the Civil Aviation Safety Authority on 22 April 2003, with the amendment becoming effective on 12 June 2003.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Safety Authority (CASA), establish specific airworthiness directives that apply to the aviation industry, particularly to aircraft and aeronautical products. This legislative instrument focuses on the R22 series helicopters, mandating corrective actions to address specific safety concerns identified in these aircraft. The directive applies to all R22 series helicopters, requiring actions to be taken in accordance with the R22 Maintenance Manual, revision 21, June 2000, specifically addressing the lower actuator bearing mounting brackets to rectify issues such as loose rivets leading to bearing misalignment and subsequent vee belt drive failure. The compliance period for these directives is set as per the R22 Maintenance Manual instructions. This legislative instrument is effective within the Commonwealth of Australia, overseen by the CASA delegate, David Villiers, and was published in the Commonwealth of Australia Gazette on 21 May 2003.
Key Provisions
The Civil Aviation Safety Regulations 1998, particularly in Part 39-105, set out specific Airworthiness Directives (ADs) for ensuring the safety of aircraft and aeronautical products. Section 39.1 (1) allows the Civil Aviation Safety Authority (CASA) to issue ADs to address safety concerns. One such AD, AD/R22/24, pertains to the Robinson R22 Series Helicopters and specifically addresses issues with the lower actuator bearing mounting brackets. This AD, amended in 2003, mandates that all R22 series helicopters must follow the requirements outlined in the R22 Maintenance Manual, revision 21, June 2000, page 2.24, section 2.410, item #8. The directive became effective on 12 June 2003, replacing the previously referenced Service Bulletin 44 (SB-44) which was cancelled at that time.
The AD imposes clear obligations on the owners and operators of R22 series helicopters. They must ensure that the action specified in the R22 Maintenance Manual is carried out to correct the identified unsafe condition. This includes verifying that the lower actuator bearing mounting brackets are properly secured to prevent misalignment of the A181 bearing, which was found to be a safety risk due to loose rivets leading to vee belt drive failure. Compliance with these requirements is essential for maintaining the airworthiness of the aircraft.
Failure to comply with the AD/R22/24 could result in serious consequences. While the regulations do not explicitly state civil or criminal penalties for non-compliance, the overarching Civil Aviation Act 1988 provides for enforcement actions that can include fines and imprisonment for serious breaches of safety regulations. The severity of the penalty would depend on the specific circumstances and the extent of the non-compliance. The main goal of these provisions is to ensure that all R22 series helicopters are maintained to the highest safety standards, thereby protecting the public and maintaining the integrity of civil aviation safety.
