SEATTLE (AP) -- Boeing may announce a fourth delay in the 787 on Wednesday when it updates its status.
A Boeing spokeswoman, Yvonne Leach, says it has been assessing the production schedule.
Last month the head of a leasing company that has ordered 74 Boeing 787s, Steven Udvar-Hazy of International Lease Finance, said he expects another delay to redesign the center wing box, which connects wings to the fuselage.
Under the schedule announced in January, Boeing plans the first 787 flight in June with the first delivery early next year, about seven months behind the original goal.
The twin-engine widebody will be the first jetliner made largely of carbon-fiber plastic that Boeing says will save fuel and be cheaper to maintain. Boeing has about 900 orders for the plane from more than 50 customers.
