Rambo, of Nashville, Tenn., was on her way to a Mother's Day performance in Texas, according to her Web site.
"She was a giant in the gospel music industry," said Beckie Simmons, Rambo's agent. "Dolly Parton recorded some of her songs."
Parton sent condolences to "everyone involved in this terrible tragedy."
"I know Dottie is in heaven in the arms of God right now, but our earth angel will surely be missed," Parton said in a statement. "Dottie was a dear friend, a fellow singer, songwriter and entertainer, and as of late my duet singing partner."
Rambo was inducted into the Nashville Songwriters Hall of Fame last year and the Kentucky Music Hall of Fame in 2006.
