Boeing Co. has started conducting flight trials of its 777-9 aircraft with US regulators on board, achieving a milestone toward certifying its jumbo airliner after years of setbacks.

The company announced that it took the initial test flight late Friday with Federal Aviation Administration personnel. Achieving so-called Type Inspection Authorization marks the start of certification flight testing, a key step in one of the most extensive commercial test efforts that Boeing has ever undertaken.
