Not quite sure what, "if properly maintained" and "spoilers rigged well", means, but I can assure you that the (5) beechjets that I am associated with are extremely well maintained and cared for (Raytheon, Jet Aviation and our own dedicated 4 mechanics). All are above RK-250 and (2) above RK-330, all of which still on warranty.
Here's a list of items that I've had go wrong in those (5) beechjets:
roll trim runaways, rudder trim actuator failure, faulty takeoff trim warnings, double generator failure twice, gcu failure, AOA failure, outflow valves failing, potable water tank exploding, hstab deice fail, itt gauge failure, standby attitude failure, standby battery failure, mfd failure, stuck/broken entry door, landing light motor failure, autopilot trim failure, reversers not stowing, igniter failure, 4 or 5 starter generator failures, windshield heater failure, trunk fuel transfer pump failure, AHRS failure and efc failures.
Now spread across a sampling of 5 different airplanes by 2 different operators, I'd say that the Beechjet has some issues. The biggest issue of all, is that most of those items above are intermittent and virtually impossible to track down.
Also, compared with the other airplane I fly regularly (800XP), there is absolutely no comparison between the two in terms of reliability. I have never had to cancel a trip on the Hawker, whereas I've had to either cancel or switch airplanes on 4 different occasions over a 3 year span.
Also, compare the beechjet to a hawker in a crosswind, and you'll see what a chore the beechjet is in a crosswind. The spoilers are such a distinct disadvantage as compared to ailerons. Personally, after over 1000 hours in the beechjet, I'd be scared of a 32 knot crosswind with the rudder pegged to floor, especially since my Simuflite checklist says 25 knot max demonstrated crosswind for takeoffs and landings.
Ask some seasoned Flight Options guys what they think of it.
