Authorities say four people were killed when a small plane crashed and burst into flames Wednesday shortly after departure near the South Carolina coast.

Federal Aviation Administration spokeswoman Kathleen Bergen said agents at the scene Wednesday confirmed that four people died in the fiery crash. The twin-engine Piper PA-23 crashed shortly after departure around 6:45 a.m. near the Summerville airport in a rural area northwest of Jedburg.

Dorchester County Administrator Jason Ward says the plane was fully engulfed in flames when firefighters arrived. The flight plan indicated the aircraft was headed to Florida.

A call to the Dorchester County coroner's office was not immediately returned.

Jedburg is around 30 miles northwest of Charleston.
