REUTERS/Jason Redmond/File PhotoWASHINGTON, Oct 11 (Reuters) - The latest version of the U.S. Senate's defense bill does not contain an amendment to extend a December deadline for Boeing Co (BA.N) to win regulatory approval for the 737 MAX 7 and MAX 10 jetliners, according to sources and documents seen by Reuters. Unless it gains an extension from Congress, Boeing must meet new modern cockpit-alerting requirements that could significantly delay the planes' entry into service. Wicker had sought to attach the measure to the version of the defense bill that was filed on Tuesday. There are other opportunities to make changes to the defense bill and an extension could be attached to other measures Congress will consider before year end.
