PARIS (Reuters) - Airbus faces a challenge to meet delivery targets for the A350 jet this year due to problems with suppliers, the head of the European planemaker said in remarks published on Wednesday.

Airbus still has to deliver at least 41 of the new long-haul jets to reach a target of more than 50 for the whole year, after a slow start blamed partly on shortages of seats and lavatories.

"The target remains a challenge because some of our industrial partners are experiencing difficulties," Fabrice Bregier, president and CEO of the planemaking division of Airbus Group <AIR.PA> told France's La Tribune daily in an interview.

Asked whether this meant problems and delays with cabin equipment from France's Zodiac Aerospace <ZODC.PA> remained unresolved, Bregier said: "The situation is improving, but not enough to allow us to meet all our commitments. Improvement plans have been launched, but too late".

Zodiac said on Tuesday the operational performance of its Cabin branch continued to be affected by problems with lavatories for the Airbus A350, but that delays in seat production were coming under control.

Bregier expressed greater optimism about production of the smaller A320neo, saying glitches with Pratt & Whitney <UTX.N> engines were being fixed and Airbus aimed to catch up with delivery plans in the second half of the year.

"It is achievable, even if it is a stretch," he said.

Bregier said Airbus did not yet have sufficient promises of orders to commit to a possible larger version of the A350 to compete with Boeing's 406-seat 777-9, and that discussions of an engine revamp of the slow-selling A380 were on hold for now.
