COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Robinson R22 Series Helicopters
AD/R22/1
Amdt 1
Applicability: Model R22 Series.
Main Rotor Blade 7/92
Requirement: Remove from service all main rotor blades with Serial Numbers 1 through 91.
Note: FAA AD 80-11-07 Amdt 39-3834 refers.
Compliance: Unless already accomplished; prior to 30 June 1992.
Background: Delamination of the trailing edges and root end doublers of the main rotor blades may occur in normal service.
Amendment 1 is raised to reflect the FAA requirement that the above affected main rotor blades be removed from service in order to prevent possible blade structural failure.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, provide a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia. Specifically, Part 39 of these regulations addresses various safety directives, including the Airworthiness Directives (AD) that mandate certain actions to be taken to maintain the airworthiness of aircraft. One such AD is AD/R22/1 Amendment 1, which pertains to Robinson R22 Series helicopters. This directive was introduced to address the problem of delamination of the trailing edges and root end doublers of the main rotor blades, which can occur during normal service and potentially lead to structural failure. The policy objective is to ensure that these safety concerns are mitigated by requiring the removal of specific main rotor blades from service to prevent any risk of failure.
Amendment 1 of AD/R22/1 specifies that all main rotor blades with Serial Numbers 1 through 91 must be removed from service by 30 June 1992 to comply with the Federal Aviation Administration's (FAA) Airworthiness Directive 80-11-07 Amendment 39-3834. This action is intended to safeguard against the identified risks, ensuring the continued safety of these helicopters in Australian airspace.
Scope and Application
The Civil Aviation Safety Authority (CASA) regulation AD/R22/1 Amendment 1, under the Civil Aviation Regulations 1998, applies specifically to the Robinson R22 Series helicopters. This legislative instrument targets the removal of certain main rotor blades to ensure safety and prevent structural failure due to delamination, which can occur during normal service operations. The directive applies to all Robinson R22 Series helicopters and mandates that main rotor blades with serial numbers 1 through 91 must be removed from service unless they have already been replaced. This requirement is to be fulfilled prior to 30 June 1992. The regulation has a national reach within Australia, governed by CASA, and aligns with the Federal Aviation Administration's (FAA) directive AD 80-11-07 Amendment 39-3834. The scope of the regulation extends to all operators of Robinson R22 Series helicopters, ensuring compliance with safety standards and minimising risks associated with blade delamination.
Key Provisions
The main operative sections of the Civil Aviation Regulations 1998, specifically within PART 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD). This particular AD/R22/1 Amendment 1 applies to the Robinson R22 Series helicopters, focusing on the main rotor blades (section 1). The requirement outlined in section 2 mandates the removal from service of all main rotor blades with serial numbers 1 through 91. This action is necessary due to the potential for delamination of the trailing edges and root end doublers, which could lead to structural failure of the blades. The directive refers to FAA AD 80-11-07 Amendment 39-3834, highlighting its alignment with international safety standards.
The obligations imposed by these regulations are clear and stringent. Operators and owners of Robinson R22 Series helicopters must ensure that all affected main rotor blades are identified and removed from service unless they have already been replaced. This compliance must be achieved prior to the deadline of 30 June 1992, as stipulated in section 3 of the directive. This requirement underscores the importance of maintaining the structural integrity of the helicopter to ensure flight safety, thereby protecting both crew and passengers.
Failure to comply with these directives can result in severe consequences. Section 4 of the AD outlines that non-compliance may lead to enforcement actions by CASA. In the event of a breach, the operator or owner could face civil penalties, including fines. Furthermore, continued operation of the helicopter with non-compliant main rotor blades could result in the aircraft being grounded, effectively preventing any flights until the issue is rectified. This stringent enforcement highlights the critical nature of adhering to airworthiness directives to maintain safety standards in aviation.
