BALTIMORE – No one was seriously injured after a helicopter carrying workers who were inspecting power lines crashed near Baltimore’s airport Saturday, authorities said.

The helicopter went down in a wooded area near a stream by Baltimore-Washington International Thurgood Marshall Airport, Maryland State Police said.

Police said the cause of the crash is being investigated by the Federal Aviation Administration.

The pilot was identified as Owen J. Garnett of Montrose, Pennsylvania. His passengers were Kevin A. Tennis of Colora, Maryland, and Jordan M. Marsh of Monkton, Maryland. The Bell 206 Jet Ranger helicopter is owned by Sky River Helicopters of New Jersey.

None of the people reported serious injuries but were taken to the hospital as a precaution, state police said.

Baltimore Gas and Electric said the workers were checking electric transmission lines for the company when the crash occurred. One of the people is an employee for the company and the other two are contractors, the company said in a statement.

The crash helicopter caught fire after it went down, causing a brush fire in the area, police said. The crash occurred near the train tracks, leading to delays for some rail passengers.

Amtrak temporarily halted all service between Baltimore and Washington before resuming it Saturday afternoon.
