17 June 1998 refers.

           This amendment does not effect the compliance requirements of the initial issue. This amendment becomes effective on 10 September 1998.
           Background:   Several separations of No. 3 bearing aft stationary air/oil seal have been experienced in service, resulting in rubbing on the disk of high pressure compressor spool stage 1-
           2. To prevent the effects due to seal separation and rubbing, this directive mandates the removal and replacement of certain spools and seals. This revision is to correct some typing errors in Requirement paragraph 3b, note (2).

           The original issue of this airworthiness directive became effective on 1 April 1998.
