- Date: March 3, 1991
- Aircraft: Boeing 737-200
- Location: Colorado Springs, Colorado, United States
- Fatalities: 25
- Phase of flight: Approach and landing
- Cause: Rudder deflected to its blowdown limit opposite to the pilots' commands, caused by a jammed secondary slide in the rudder power control unit servo valve; the NTSB's original 1992 report had not identified a cause and was revised later.
United flight 585 from Denver to Colorado Springs rolled steadily right and pitched nose-down after turning final at Colorado Springs in visual conditions. The 737 hit the ground in Widefield Park, and all 25 aboard died. The NTSB later traced the loss of control to the rudder driving to its blowdown limit.
