Reading the preliminary BFU report puzzles me and makes me think: how could people like that be allowed to fly such a demanding airplane? How was the crew's performance during their latest recurrent trainings? Has nobody noticed anything before that accident?
Gear and landing flaps fully down, spoilers extended (?), power at 34%? The Citation X won't maintain level flight like this.
Why on earth being constantly below a 3 degree glideslope (and below the PAPI of 4,4 degrees) 4 miles from the runway, 500 ft above the ground, fully configured and with a rate of descent of 1,200 FPM?
It appears that they never overflew the point YANKEE ONE but rather intercepted the final course just before reaching the next point YANKEE TWO, losing altitude at a moderate rate at first. Can there still be any doubt about the concept of a stabilized approach?
Why going to this unfamiliar airfield, at night and in marginal weather in the first place? Maintaining VMC...
And then the crew's reaction to the EGWS alert, the last line of defence. Unbelievable.
