PARIS (Reuters) - Steep losses at planemaker Airbus pushed European aerospace group EADS (EAD.PA: Quote, Profile, Research) further than expected into the red last year, hitting its shares as it also disappointed investors with a cautious profit forecast.

Chief Executive Louis Gallois said the group was turning the corner after a slew of production delays but faced a challenge from the relentless rise of the euro against the dollar, which sliced $1 billion off revenue at the Airbus subsidiary in 2007.

Gallois said the planemaker was looking at adding to its Power8 restructuring plan, which involves 10,000 job losses and half a dozen factory sales, and took the unusual step of revealing an internal clash over operating business forecasts.

EADS's 2007 net loss of 446 million euros ($685 million) compared with a slender 99 million euro profit in 2006 and an average market forecast of a 329 million loss.

"I am not happy with the 2007 figures but I believe their underlying strength will allow an improvement in performance as we move forward," Gallois told a news conference.

"We have prepared the future and cleaned up a lot of the past," he added.

Shares in Europe's biggest aerospace and defense group fell up to 7 percent on the results which also included a below-consensus operating profit of 52 million euros, down from 399 million in 2006. At 1442 GMT they were down 5.2 percent at 16.39 euros.

Group revenue dipped to 39.1 billion euros from 39.434 billion, due mainly to the recent slide in the dollar.
