Boeing starts building first Next-Generation 737 at increased production rate

Boeing is starting assembly this week of the first Next-Generation 737 to be built at the increased rate of 42 airplanes per month. Since 2010, production of the 737 has increased about 33%, from 31.5 to 42 airplanes a month, its highest rate ever. On February 5th, Mechanics will load initial parts of the spars – internal support structures in the wings – into an automated spar-assembly machine. The spar is the first step in building the wings and marks the start of the assembly of the airplane at the Renton, Wash. factory.
