A United Airlines jetliner that made an emergency landing in Grand Junction, Colo., over the weekend after an engine shut down is grounded until the Federal Aviation Administration reviews the airline's investigation and repairs.

FAA spokesman Mike Fergus said Monday the usual process is to give the airline time to fix the problem, unless an accident was involved.

The Boeing 757 was flying from Denver to Los Angeles on Sunday with 125 passengers and crew members on board when one of its two engines shut down. The flight was diverted to Grand Junction Regional Airport, where passengers were put on another plane.
