Boeing Co. doesn’t expect its 737 Max 10 model to be ready for certification until next summer at the soonest, US aviation regulators told a key lawmaker.

The planemaker’s latest plan was relayed in a letter Monday from Federal Aviation Administration acting Administrator Billy Nolen to Senator Roger Wicker, a Mississippi Republican. The comments provided the latest indication that the plane won’t meet a crucial deadline to finalize its approvals by the end of 2022.
