If the clearance is .200 inches or more, but is less than .250 inches: inspect at intervals not to exceed 75 hours time in service until clearance is .250 inches or more, at which time replacement is required. b. If the clearance is less than .200 inches, inspect at intervals not to exceed 250 hours time in service, until the clearance is .200 inches or more. Note: These wear and clearance limits differ from, and take precedence over, the limits contained in the service information. 2. Before 6 June 1992. The compliance times remain unchanged for the Requirement 1 P/N 2-1203-3 brake initial inspection, and the Requirement 2 modification. This Airworthiness Directive becomes effective on 28 December 2000. Background: Wheel brake system malfunctions have occurred on several of the affected aircraft where regular brake system maintenance had been performed. The actions specified by this Directive are intended to prevent wheel brake system malfunctions that could result in a fire in the brake area. Amendment 1 is issued in response to a new FAA AD which incorporates inspection and replacement requirements for additional landing gear brake assemblies. The FAA AD specifies wear and maximum clearance limits which take precedence over those specified in the service information. The original issue of this Airworthiness Directive became effective on 6 March 1992. David Alan Villiers Delegate of the Civil Aviation Safety Authority 8 November 2000 The above AD is notified in the Commonwealth of Australia Gazette on 22 November 2000.
