(Reuters) – U.S. lawmakers introduced a bipartisan bill on Tuesday that would reform aircraft certification following two fatal 737 MAX crashes, U.S. Senators Roger Wicker and Maria Cantwell said in a joint release.

Top Republicans and Democrats on the U.S. Senate commerce committee struck a deal on the proposal that would if enacted revise aircraft certification rules.

The proposal includes only technical changes from a draft circulated last week, people familiar with the matter said.
