Federal accident investigators say they're looking at options for recovering aircraft parts found in the search area for air ambulance that disappeared in Alaska with three people on board in January.

Clint Johnson, chief of the National Transportation Safety Board in Alaska, says the plane's black box recorder was recovered Monday evening during a search for the missing King Air 200 commissioned by Guardian Flight, the Utah-based company that owns the missing plane.

He says there also are plans to ultimately recover a landing gear and engine also were located in the same waters of Fredrick Sound, but adds those plans may change.

Johnson says an NTSB investigator is on board the recovery boat at the southeast Alaska site and has possession of the black box, also known as a cockpit voice recorder.

The plane disappeared with three Guardian Flight employees Jan. 29 flying to pick up a patient in the southeast community of Kake.

The company, based in Utah, says it continues its search for the three people on the plane. It disappeared Jan. 29 flying to pick up a patient in the southeast community of Kake.

The pilot, flight nurse and flight paramedic were Guardian Flight employees.
