Boeing Co on Wednesday posted a quarterly net loss on charges related to the first three 787 flight-test planes and the 747 program.
The world's second-largest plane-maker, after EADS unit Airbus, said the net loss was $1.6 billion, or $2.23 per share, compared with a profit of $695 million, or 96 cents per share, a year earlier.
The latest results reflect the reclassification, to research and development, of costs incurred through July for the first three 787 flight-test airplanes, spending on those planes for August and September, and the 747 charge.
Revenue rose 9 percent to $16.7 billion. The year-ago period was impacted by a labor strike.
Revenue from its commercial airplane division increased 13 percent to $7.9 billion on higher deliveries. The division booked 96 gross orders during the quarter, while 17 orders were canceled. Contractual backlog was $254 billion.
Boeing's Integrated Defense Systems saw third-quarter revenue up 3 percent to $8.7 billion on increased military aircraft deliveries.
The company said the first flight of the long delayed 787 Dreamliner remains on track to occur by the end of 2009, with first delivery scheduled for the fourth quarter of 2010.
To reflect the 787 and 747 impacts, earnings guidance for 2009 has been changed to a range of $1.35 to $1.55 per share, from $4.70 to $5.00 previously.
