Fast-Tracked Aircraft Certification, Pushed by Boeing, Comes Under the Spotlight

Boeing Co. and its lobbyists for years pushed to speed up the time it takes to get a new plane certified to fly. Congress and the Federal Aviation Administration—which were both targets of the company’s multimillion-dollar lobbying—supported efforts to delegate some safety-certification functions to Boeing.
