Prosecutors are proposing a nonprosecution agreement to resolve Boeing’s violation of an earlier settlement.

A decision by the Justice Department not to pursue a guilty plea from Boeing would be the latest about-face in a long effort to hold the plane maker accountable for the crashes of two 737 Max jets.

The Justice Department advised families of victims of two 737 Max crashes that it was considering a plan to drop a previous agreement under which Boeing would have pleaded guilty.
