What was the first PG-13 movie released by Disney itself instead of one its studios?

The first PG-13 movie released by Disney itself, rather than one of its studios, was "The Rocketeer" in 1991.

While Disney had released PG-13 films before, such as "The Black Hole" (1979) by Disney's subsidiary, Walt Disney Productions, "The Rocketeer" was the first film produced and distributed directly by Walt Disney Pictures, the company's main film production arm, with a PG-13 rating.
