Aircraft maker Airbus hopes to get certification for its new long-haul A350 model by the end of September, its Chief Executive Officer Fabrice Bregier said on Tuesday.
"We have finished all the tests for certification and we hope to have it by the end of September," Bregier told reporters.
"To my knowledge nothing more needs to be done to have the certification."
To date, 750 A350 aircrafts have been ordered. The first of the aircraft family, the A350-900, will enter service at the end of the year with an initial delivery to Qatar Airways.
However, it must first get certification from civil aviation authorities the European Aviation Safety Agency and the US Federal Aviation Administration.
Bregier also said that the A320neo, a re-engineered version of the best-selling A320 that offers fuel savings of up to 20 percent, should make its first flight this week.
"On Thursday if weather conditions are good and there is no last-minute issue, the A320neo with Pratt & Whitney engines will make its first flight," Bregier said on the sidelines of an event at the French Chamber of Commerce in Great Britain.
The new unit is expected to enter service in the fourth quarter of 2015.
