Boeing 757 And 767 Production Efficiency

Wed Dec 08, 2004 1:24 pm

It seems like the 767 will be in production for a few years longer then the 757. My question is, why did Boeing decide to produce the the two planes separately? They were designed together and have a great deal of commonality with each other. However Boeing began 757 production in Renton and 767 in Everett which is over 30 miles away.

It seems like they could have saved costs by having the planes produced side by side. the 757 and 737 aren't very similar with the exception of being narrowbodies, and likewise the 767 and 747 don't share much in common either. There have been a number of threads about Boeing production efficiency recently and how it isn't as good as Airbus. So why did Boeing put themselves at a disadvantage from the beginning by eliminating the economies of scale of an integrated production system? Was it due to land space, unions, or some other reason? If they were produced side by side, then would the 757 probably still be in production rather then getting phased out because of poor sales and in favor of increasing 737 production?

Any comments are appreciated.

The reason the 757 and 737 are better suited to be built together is because they have the same fuselage crossection and are much easier to park in the smaller building at RNT, while the Everett plant was built specifically for the 747 and other widebody planes. It is the largest building in the world and is what is needed to house the wider planes. The Commonality betweed the 757 and 767 has more to do with their cockpit and flying dynamics and design, so little is gained by building them together

Much of the 757 was produced in Wichita, alongside the 737. Parts for both aircraft were transported to Renton for final assembly. So there are some common systems, but there in some ways, the 757 had more in common with the 737 than 767. You can't transport the 767 parts as easily...much of it had to be produced in-place.
