Watch live: FAA chief testifies before House on Boeing shortfalls

Federal Aviation Administration (FAA) Administrator Michael Whitaker will testify Wednesday afternoon before the Senate's Homeland Security investigations subcommittee in a hearing entitled "FAA Oversight of Boeing’s Broken Safety Culture."

Aerospace giant Boeing has seen multiple, highly public technical failures this year, including the mid-air blowout of a door plug from Alaska Airlines Flight 1282 in January. The Boeing 737-9 MAX made an emergency return landing at Portland's airport with no fatalities. Passengers were shaken, and several required short term medical care for apparently non-life-threatening injuries.

Whitaker's testimony also comes after 33,000 Boeing machinists went on strike earlier this month. On Monday, the company made what it termed its "best and final" offer to their union, proposing a timeline for wage hikes and increased retirement contributions.

He is expected to appear before the committee at 2 p.m. EDT.
