Assistant Chief Kim Iannucci of the Sacramento Fire Department said emergency crews about 6:40 p.m. responded to the golf course at 6801 Freeport Blvd.
She said the small plane, a Piper PA-28, had taken off from Sacramento Executive Airport. Witnesses said they heard it sputter, then saw it turn and go into a wooded area of the golf course.
One wing of the plane was damaged in the crash, Iannucci said.
Assistant Chief Scott Williams, who was on scene, said witnesses reported that the plane's engine had died and it appeared the pilot was attempting to return to the airport.
Witnesses helped the men out of the plane and both were walking around when firefighters arrived. The names of the men were not released. Williams said the passenger was a law enforcement officer with an agency in the Sacramento region, but not with the Sacramento County Sheriff's Department as initially reported.
Federal Aviation Administration online records show the plane is registered to Capitol Flying Inc. of Antelope.
The men suffered injuries that were not life threatening, according to Sacramento Police Department officials.
A Level 2 hazmat incident was declared due to fuel that leaked from the plane. Iannucci said one of the witnesses at the golf course was a pilot and was able to shut off the fuel, helping to stem the leak.
