MILAN, July 9 (Reuters) - Italian aerospace and defence group Finmeccanica (SIFI.MI) will extend the average expiry of its debt to 7.8 years from 6.5 years with its dollar bond issue this week, Chief Financial Officer Alessandro Pansa told Reuters on Thursday.

In April Pansa told the annual shareholders' meeting that the company's debt had an average expiry of 6.5 years and that it planned to extend that to eight years within two years.

He added that the dollar issue, which was in a 10-year and a 30-year tranche, left around 1 billion euros ($1.39 billion) still to finance from a 3.2 billion euro loan used to buy U.S. group DRS Technologies in a deal announced in May 2008.

"Mid-2010 there is a tranche for 750 million (euros) of the original loan and mid-2011 there is a second tranche of 800 million (euros)," Pansa said.
