Probe finds no problems with plane

Investigators from the National Transportation Safety Board say they have found no mechanical problems in the single-engine plane that crashed in Greensburg Sunday night, killing four people. The NTSB said the Piper Malibu had fuel and appeared to be working well mechanically before plunging into a field. The pilot, Don Horan, had accumulated a total of nearly 400 hours of flying time. Horan’s wife, Barbara, also died in the crash along with family friends Stephen and Denise Butz.
