COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Robinson R22 Series Helicopters
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/R22/30 Amdt 4 and issues the following AD under subregulation 39.1 (1) of CAR 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 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.
AD/R22/30
Amdt 5
Applicability: All R22 helicopters.
Main Rotor Spindle 1/2002
Requirement: 1. Action in accordance with the Compliance Procedures of Robinson Service Bulletin (SB) No. 60A.
2. Visually inspect the reworked spindles and A106 Rev 0 or subsequent journals installed in accordance with Requirement 1, for cracks.
Note 1: This directive applies to all R22 helicopters regardless of serial number. The US FAA has determined that all R22 helicopters could be affected, not just those identified in the Requirement Document.
Note 2: FAA AD 88-26-01 R2 Amdt 39-6646 refers.
Compliance: 1. Before 28 April 1989.
2. Within 500 hours time in service after 23 March 2000, and thereafter at intervals not to exceed 500 hours time in service.
This amendment becomes effective on 24 January 2002.
Background: A crack was found in a main rotor spindle after a balance check of the main rotor could not be achieved. Upon rotor blade removal, a crack was found running from the spindle bolt hole to the spindle upper surface. Failure to detect the crack would have resulted in blade separation. Amendment 3 corrected the related FAA AD reference.
Amendment 5 is issued to clarify applicability of the Airworthiness Directive. The related FAA AD applies to all R22 Helicopters, not just those identified by serial number in Robinson SB 60A.
Amendment 4 of this Airworthiness Directive became effective on 23 March 2000, and was issued to correct an anomaly in the repetitive inspection requirement.
