EVERETT, Wash. (AP) — Boeing Co. said Monday it has finished fixing structural problems in two more of its 787 jetliners. The flaws had forced the airplane maker to further delay delivery of the highly anticipated plane earlier this year.

Chicago-based Boeing said last week it has completed similar repairs to the first of six test versions of the plane, which is built for fuel efficiency with lightweight carbon composite parts.

Boeing cited the problem — weak points near the area where the wings attach to the fuselage — when it postponed the 787's first test flight and deliveries for a fifth time in June, putting the plane more than two years behind schedule. Repeated delays of the 787 have cost Boeing credibility and billions of dollars in anticipated expenses and fines.

Shares of Boeing edged up $1.32, or 2.6 percent, to $52 in morning trading.
