American Eagle was wrong when it said that the left engine of a plane that crashed had been repaired hours earlier, the company said Friday.

The American Eagle plane with an engine that would not start Tuesday was in Nashville, Tenn., airline spokesman Tim Kincaid said. It was not the plane that crashed Tuesday night on approach to Raleigh-Durham International Airport, killing 15 of the 20 people aboard.The mistake was made because of nearly identical identification numbers between the two Jetstream 3200 aircraft, Kincaid said.

"We are very embarrassed," he said. "We regret the error and any problems or any inconvenience it caused."
