The NTSB said the Piper Malibu had fuel and appeared to be working well mechanically before plunging into a field in Decatur County.
Horan’s wife Barbara, 44, also died along with two family friends: Stephen Butz, 45, and his wife, Denise, 42. The couples were returning from a weekend trip in Florida. The investigation now turns to how much of a factor weather played in the crash. Conditions in Greensburg were foggy on Sunday night when Horan was attempting to land.
Visitation for the victims is Thursday in Greensburg. Funeral services follow on Friday.
