series magnetos, inspect and if necessary, replace Bendix rotating magnets identified in the Detailed Instructions of TCM Ignition Systems Mandatory Service Bulletin MSB644 dated 4 April 1994 with appropriate serviceable rotating magnets. (Ignition coils of the S-600 series magnetos already incorporate the improved design.)

           For the Bendix S-1200 series magnetos, inspect and if necessary, replace Bendix ignition coils identified in the Detailed Instructions of TCM Ignition Systems Mandatory Service Bulletin MSB644 dated 4 April 1994 with appropriate serviceable ignition coils. (The rotating magnets of the S-1200 series magnetos already incorporate the improved design.)

           Note: Previous compliance with AD/ELECT/53 Amdt 2 or earlier issues of that Directive does not constitute full compliance with this Directive, similarly compliance with Bendix Electrical Components Division Service Bulletin 560 or 560A would not constitute full compliance.

           Compliance:  The original compliance remains unchanged as within the next 100 hours time in service after 10 November 1994. This amendment is effective from 14 September 1995.

           Note: FAA AD 94-01-03 R2 Amdt 39-9271 refers.

           Background:  The original issue of this Directive superseded AD/ELECT/53 Amdt 2, which was cancelled. Reports are still being received of `clear case coils" being identified during magneto servicing, compliance with this Directive, whilst ensuring that all coils of this type are finally removed from Australian aircraft, will also ensure that older style rotating magnets are removed.

           This amendment is issued to clarify the applicability statement and reflects the issue of a revision to the FAA Airworthiness Directive, no further action is required if magnetos are in compliance with the original issue of this Directive.
