From Boeing investor guidance..
Boeing Co has told some 737 MAX owners it is targeting U.S. Federal Aviation Administration approval of its software fix as early as the third week of May and the ungrounding of the aircraft around mid-July, two sources told Reuters.
The dates are part of a provisional timeline that Boeing has shared in meetings with airline customers as it explains an upgrade to software that played a role in two fatal crashes and led to the worldwide grounding of its MAX 737 jetliner in March.
However, Boeing has not yet submitted its completed software package to the FAA for approval, two other sources said.
