Washington ? The Pentagon’s inspector general found that officials followed improper procedures in 2001 and 2002 in negotiating the price of a $1.32 billion contract with Boeing Co. to upgrade some NATO radar aircraft.

As a result, it is unclear whether the price tag is reasonable, the inspector general said in a report released this week.

Boeing said it would renegotiate the deal. Pentagon officials said they expected a lower price.

In 2001 and 2002, the U.S. military’s senior negotiator with Boeing was Darleen Druyun, then the principal deputy assistant secretary of the Air Force for acquisition and management. The final price was agreed upon Sept. 26, 2002, according to the inspector general’s report.

In fall 2002, Druyun also was allegedly in negotiations with Boeing’s chief financial officer, Mike Sears, for a job, and was reviewing a proposal for a multibillion-dollar air tanker-leasing contract between the company and the Air Force.

The report does not specify any wrongdoing by Boeing.
