PORTLAND — Several Portland area fire and rescue departments responded to the Portland International Jetport tonight after a commercial airline pilot reported problems with his landing gear.

Paul Bradbury, the jetport’s director, said the pilot, who was approaching from the west with about 20 passengers on board, called the jetport tower to report that his cockpit instrument panel indicated his landing gear was malfunctioning.

However, the landing gear worked properly and the plane landed safely around 9:30 p.m., Bradbury said.

Bradbury said the twin-engine turboprop plane is one of the smaller commercial planes that operate out of the jetport. He did not know which airline the plane belongs to.
