NTSB: No initial theory for Moab plane crash

Federal investigators say there's no evidence that a twin-engine airplane that crashed near Moab and killed 10 people had any kind of "in-flight structural failure."

A preliminary report from National Transportation Safety Board investigators doesn't offer any theory about why the plane crashed and burned Aug. 22.

The crash killed nine employees of a Cedar City skin care company and the pilot. The crew was returning to Cedar City after spending the day in Moab treating patients at a clinic.

No one saw the crash. The NTSB says two pilots on the ground at the Moab airport heard the plane take off and said everything sounded normal. About 15 minutes later, one of the pilots went outside and saw smoke in the distance.

The NTSB says the plane crashed in hilly terrain about 1.2 miles from the airport. Most of the plane was consumed by fire after the crash.

The crash remains under investigation.
