EVERETT, Wash. -- On Wednesday, the Boeing Company announced they're pushing back the inaugural flight of the new 787 Dreamliner. Boeing stock fell nearly $4 a share Thursday after rising to a record high on Wednesday.

A supply company that helps to build the 787 said it isn't worried by the small delay.

Complete Deburr,Inc., a metal shop in Snohomish County, is deburring parts for the plane. The work is one of the last finishing steps before the parts are coated and handed over to Boeing for assembly.

There are currently 683 orders for the Dreamliner from 47 customers.

The entire industry is waiting to see the 787 fly for the first time, but Boeing said Wednesday they've pushed back the maiden flight from late August or early September to late September.

According to the Seattle Times, development costs for the Dreamliner are millions higher than anticipated, and that the company needs more employees than expected to keep the work on schedule.

Company officials said the delay will not affect the first delivery date set for next May.
