PORTLAND (AP) – A USAirways Express jet landed safely Tuesday morning after reporting a hydraulic problem, officials said.

Airport emergency crews responded but the Canadair Regional Jet landed without incident at about 10:40 a.m. and taxied to the passenger terminal under its own power, said Kevin Sullivan, spokesman for the Portland International Jetport.

There were 30 people aboard Flight 4406, which had originated at Reagan National Airport in Washington, D.C., Sullivan said.

The pilot reported that an indicator in the cockpit showed there was low hydraulic pressure in one of the plane’s systems, Sullivan said. It was unclear whether it was a real problem or just a faulty gauge, he said.

One of the passengers said no one was told of a problem before the plane landed. Fire trucks were positioned at the end of the runway.
