The Federal Aviation Administration says two of four people aboard a private jet that crashed in a northern Indiana neighborhood have died.

Authorities say the Beechcraft Premier I twin-jet flying out of Oklahoma apparently was experiencing mechanical trouble when it crashed late Sunday afternoon in South Bend. It struck three homes, becoming lodged in one of them.

Federal Aviation Administration spokesman Roland Herwig in Oklahoma City says two people on the plane were killed. Two others aboard were injured, as was one person on the ground, officials said. Officials say none of the survivors had life-threatening injuries.

A South Bend fire official says they believe everyone connected with the damaged homes has been accounted for.

An investigator with the National Transportation Safety Board arrived on the scene late Sunday.
