Requirement: Due to possible elevator flutter, further flight is prohibited. (LBA AD 2001-317 refers) Compliance: Effective immediately. Effective Date: 18 October 2001 Section 72I(3)(a) of the Civil Aviation Act 1990 requires NZ airworthiness directives to be notified in the New Zealand Gazette. This cannot be achieved until 18 October 2001 and hence is the effective date of the AD. While the AD does not legally become effective until then, the AD does address a serious un-safe condition and should be accomplished immediately.
