Boeing has confirmed that final assembly of the newest member of the 787 family will take place exclusively at its North Charleston plant in South Carolina because the -10’s longer fuselage is too large to transport.
From nose to tail the 787-10 will be 5.5m longer than the -9, with the midbody section alone being 3m longer than the -9. This means that the section is too long to be “transported efficiently” to Boeing’s Everett facility in Washington for final assembly, the OEM has confirmed.
In its announcement, Boeing confirms that its Everett plant will focus on building 787-8 and -9. The first 787-10 is due to being final assembly in 2017.
