Ann: An update from the Executive Chairman, page-173

As per the Chairman's Update:

“The current milestone dates for the remaining tasks that has been issued to us by Boeing on Nov 30 are as follows:

Dec 18 – Resubmit Cert Plan to FAA
Jan 15 – Complete Cert Plan Deliverables
Jan 15 – FAA acceptance of Cert Plan
Jan 15 – Route CVM deliverables to ODA for approval/recommend approval
Mar 1 – Submit CVM deliverables to FAA (Service Bulletins and Compliance Report
May 15 – FAA Approval of Deliverables
June – SB Release with AMOC"

“While we cannot guarantee that any of these dates won’t change again we are sharing them at this time to confirm our confidence that the formal approval process is well advanced and into its final stages, and our judgment (and that of others familiar with the Boeing/FAA certification process) is that this schedule, even if being constantly updated, is evidence of Boeing’s commitment to the success of the project and the FAA’s engagement at a detailed level."
