Fourth Allegiant Air flight diverted in a week

CHATTANOOGA, Tenn. — An Allegiant Air flight made a safe emergency landing Thursday at a Tennessee airport, the fourth time an Allegiant flight from Florida has been diverted in about a week.

Chattanooga Airport spokesman Albert Waterhouse said Allegiant Air Flight 760 landed at about 8:30 a.m. Thursday after reporting an engine problem. No injuries were reported.

Allegiant Air said in a statement that the plane has been taken out of service and will be inspected.

The statement said the flight, which was headed from Sanford, Florida, to Cedar Rapids, Iowa, had 150 passengers and six crew members. Allegiant said a replacement aircraft will take passengers on to Iowa.

At least three other Allegiant Air flights from Orlando Sanford International Airport have been diverted for emergency landings in the past week.

A flight to Bangor, Maine, landed at T.F. Green Airport in Warwick on Wednesday when passengers reported an abnormal smell. The airline said the problem was traced to a leak in an air duct. The passengers were offered rooms for the night, and 108 of them left T.F. Green Airport this morning on a flight to Bangor.

A flight to Wisconsin landed in North Dakota on Tuesday after having a problem with deicing equipment, which was fixed.

On Christmas Eve, a flight to Youngstown, Ohio was diverted to Jacksonville, Florida, because of what turned out to be a faulty indicator light.

The airline said in an e-mail to NBC 10 News that "Allegiant is a very safe airline. We have robust internal and external auditing programs and are investing heavily in new training programs and technologies that are industry leading."
