TSB31-B is going through a 30-day default ballot period, which ends today, May 15. The editors are working on the editorial changes to the document, which will not be published until we have the Part 68 Harmonized Rulemaking, which is scheduled to be issued in the summer. TSB31-B is based exclusively on the Harmonized Part 68 Sections. Regards. Anh Wride.
