A single-engine Cessna 172 carrying a pilot and the 19-year-old woman landed at the local airport about 7 p.m. and taxied to a ramp, said Jim Peters, spokesman for the FAA in New York, N.Y.

According to Kevin Daugherty, airport manager at Frederick Municipal Airport, the injury occurred on the ramp in front of the main terminal building.

The woman had been sitting on the left side in the two-seater aircraft. She got out and was walking around the front of the plane toward the restaurant in the terminal when the propeller struck her right arm, according to Lt. Richard Hetherington of the Frederick Police Department.

A portion of her arm was partially severed, Hetherington and Peters said.

Police did not name the injured woman or the pilot, who was a friend of the victim and also a flight instructor, Hetherington said.

When Frederick Police officers arrived about 7:10 p.m., a Maryland State Police flight medic was already on the scene. Hetherington said. The injured woman was flown to Union Memorial Hospital in Baltimore, which has hand and arm specialists that are among the best in the country. Police did not know her condition Friday evening.

Airplanes based out of other airports normally stop in the transient aircraft line in front of Landmark Aviation, Daugherty said. It struck him as unusual that this plane stopped in front of the terminal building, though he said it might have been because the pilot was not familiar with the airport.

The airplane involved in the incident was based out of Martin State Airport, in Baltimore, and returned there Friday morning about 11:30 a.m., he said.

According to the FAA website, the aircraft is owned by a Laurel-based company called 210 Centurion Group LLC. A call placed to the address listed on the website was not returned Friday.

Peters said the National Transportation Safety Board is conducting an investigation, which is standard procedure when someone suffers a severe, airplane-related injury.
