WASHINGTON (Reuters) -U.S. Federal Aviation Administration chief Michael Whitaker will travel to Seattle early next week to meet with Boeing as the agency audit's the planemaker's 737 MAX production process following a mid-air emergency. Boeing, which makes the 737 MAX in the Seattle area, was hit by the latest in a series of problems on Jan. 5 when a panel flew off one of its 737 MAX 9 jets in mid-flight.
