Human Factors
During a flight to STS; the Captain and I briefed the RNAV 14 approach into STS. Our briefings overlooked the step down fix UCEVE at 1700 feet. Because of this oversight; we descended from 3300 feet at EHETY to around 700. This is where we received a terrain climb alert and went missed approach.
After crossing EHETY I instructed the non-flying pilot to set MDA; We flew down to the MDA and then got a Terrain warning. I called for go around; we executed the go around and got vectors for another approach.
CE560XLS flight crew reported omitting the step down fix UCEVE with a crossing altitude of 1700 feet during the RNAV 14 approach to STS. This resulted in a terrain warning and a go-around was initiated.
