PHOENIX >> A Delta Air Lines flight from Atlanta to Phoenix has landed safely after one of the plane’s engines shut down as it began to descend over Arizona.

Delta spokesman Paul Skrbec says Flight 2046 carrying 159 passengers landed normally Saturday afternoon at Phoenix Sky Harbor International Airport. It taxied to the gate under its own power.

The Boeing 757’s left engine shut down as the plane began to descend, so the captain followed procedure and declared an emergency. Skrbec says there were no injuries but the airline apologized to the passengers.

The twin-engine 757 can fly safely on just one of its two engines.
