Medium-size airports in Toledo, Ohio; Rockford, Ill., and Huntsville, Ala., are among those asking the Federal Aviation Administration for approval to receive the massive 747-8 freighter. Boeing expects to deliver the first planes to customers later this year.

The airports are eager to grab a share of the air-cargo market, which is growing faster than passenger traffic as the economy recovers. But some residents feel threatened by the big cargo planes currently flying over their homes and doubt Boeing’s claims that the new 747 won’t be as noisy.

The 747-8 is the biggest airplane Boeing has built, with a wingspan 11 feet wider and a body 18 feet longer than the current 747-400 model. Despite its size, Boeing says the 747-8’s engines will be 30 percent quieter.

Dealers warned of Toyota shortages

DETROIT | Toyota Motor Corp. is telling U.S. dealers that new vehicles could be in short supply this summer.

In a memo to dealers obtained Monday by the Associated Press, Toyota’s U.S. general manager, Bob Carter, said new-vehicle supplies could be “significantly impacted” owing to production slowdowns in Japan and North America.

Toyota has had trouble getting some parts after its suppliers were damaged by the March 11 earthquake and tsunami in Japan.

Mr. Carter said plants won’t be running at full capacity this month and that production schedules haven’t been set for May through July.

Toyota also says some paint colors won’t be available because of damage to a supplier.

Still, Mr. Carter said the company is optimistic about April sales and has more than 300,000 vehicles in stock.
