Boeing sees FAA approving software fix in May, MAX ungrounding in July: Sources

Boeing has told some 737 MAX owners it is targeting US FAA approval of its software fix as early as the third week of May and the ungrounding of the aircraft around mid-July, 2 sources said. 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 2 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, 2 other sources said. None of the sources said they knew for sure how long the re-certification process will take. Boeing CE Dennis Muilenburg said last week the company had made the final test flight with the new MAX software before a final certification flight. <br/>
