A month and a half after a General Electric engine failure aborted a Boeing 787 Dreamliner pre-flight taxi test in North Charleston, another GEnx engine has failed, this time as a 747 freighter jet was preparing to take off from Shanghai Tuesday night.

A GE spokesman said the cause of the latest failure in China has not been determined, but the Wall Street Journal, citing an unidentified person, said it “appeared to stem from a similar problem” as the July 28 mishap at Charleston International Airport.

The National Transportation Safety Board determined that the Dreamliner GEnx engine’s driveshaft fractured, but does not yet know why. In the meantime, other in-service GEnx engines have been inspected and continue to fly.

WASHINGTON — The number of Americans seeking unemployment benefits jumped to the highest level in two months, although the figures were skewed in part by Hurricane Isaac.

Applications increased by 15,000 to a seasonally adjusted 382,000, the Labor Department said Thursday. That’s up from 367,000 the previous week. The four-week average, a less volatile measure, increased for the fourth straight week to 375,000.

Isaac made landfall as Category 1 hurricane on Aug. 28 in Louisiana. It disrupted work in nine states.

WASHINGTON — A sharp rise in gasoline costs drove up wholesale prices last month by the most in more than three years. But outside energy and food, price gains were mild.

The producer price index, which measures price changes before they reach the consumer, jumped 1.7 percent in August, the Labor Department said Thursday. The increase was mostly because gas prices soared 13.6 percent, the biggest gain in three years. Food prices rose 0.9 percent.

WASHINGTON — The average rate on the 30-year fixed mortgage held steady this week, staying slightly above the lowest level on record.

Mortgage buyer Freddie Mac said Thursday that the rate on the 30-year loan was unchanged at 3.55 percent. The average on the 15-year fixed mortgage slipped to 2.85 percent, down from 2.86 percent.

NEW YORK — The Walt Disney Co.’s TV advertising revenue did not rebound as expected after last month’s conclusion of the hugely popular London Olympics that were aired on rival NBC, the company’s chief financial officer said Thursday.

Disney also expects to book a $50 million charge for discontinuing a movie that was in the works, Jay Rasulo said. The film write-down will trim profits by 2 cents per share in the three-month period that ends this month, Disney’s final quarter of its fiscal year.

The write-down was for an untitled stop-motion animation movie. The movie had been slated for release in October 2013.

NEW YORK — USA Today, the nation’s second-largest newspaper, is unveiling an overhaul of its printed and digital editions for the second time in less than two years.

USA Today’s print version will introduce a redesign today. It changes the logo for the first time in its 30-year history and nearly doubles the number of pages that use color.

Meanwhile, Gannett’s flagship national daily is changing the look and feel of its website and mobile apps. Readers will have to click or finger through pages as if they are perusing a digital magazine.

But even as it makes changes, USA Today is resisting charging for access.
