(KTVU/CNN) - Almost a year after the deadly Asiana Airlines Flight 214 crash at the San Francisco International Airport, the NTSB is expected to reveal the official cause of the accident Tuesday.
The board will hold a meeting to vote on what likely led to the crash that left three dead and 200 injured.
Federal investigators have said inexperience in the cockpit contributed to the crash. But safety officials will weigh whether plane manufacturer Boeing created a system too complicated for pilots to understand.
