Federal Aviation Administration spokesman Roland Herwig confirmed two of the four people aboard the jet died, WSBT-TV and the South Bend Tribune reported. Two people were hospitalized in fair condition and one in serious condition, the news outlets said.
South Bend fire officials said the Beechcraft Premier 1 with tail number N26DK out of Tulsa, Okla., touched down on a South Bend airport runway about 4:30 p.m. local time, then started to climb again before crashing.
The FAA said the pilot had reported a problem with electrical power as the aircraft approached the airport, WSBT-TV and the Tribune said.
One resident, Stan Klaybor, said the plane clipped the top of one house, heavily damaged a second and wound up against a third.
A South Bend fire official said efforts to find survivors was made dangerous because of jet fuel that leaked and structural damage to the house where the plane stopped.
