Narrative:

This event occurred during landing at ZZZ1 on runway 36 C. The touchdown was very soft and the landing roll out was totally normal at first. I flew the nose wheel down easily to the runway and added forward pressure.after touching down and after applying reverse thrust; and after reaching about 85 knots during deceleration; I began applying the brakes very slightly and smoothly. At that moment the master caution light illuminated along with an amber antiskid fail cas message; and simultaneously I felt the wheels slip and heard a loud squeal/skid noise.I immediately released the brakes and the amber antiskid fail cas message immediately extinguished. From the time we saw the cas and master caution and heard the squeal to the time it extinguished and I released brake pressure was about 1 second.we did not notice any change in ground handling during the taxi off of the runway and/or to the ramp; and there were no unusual sounds or anything of the sort to indicate that a tire was flat.however while being marshalled in we noticed that the lineman was staring at our left main gear assembly.after opening the door we noted that the left inboard main tire (# 2) was flat. The runway at ZZZ1 was mostly clean; with areas of dry patchy snow minimal and some patches of dry frozen ice. Braking action had been reported as good.the conditions at the departure airport 1 hour prior were light rain with above freezing temperatures; approximately 6 degrees C; and no standing water.this was the second malfunction of a similar kind in less than two weeks on a separate identical airplane.I believe we should have the manufacturer take a very close look at the problems they are having with the anti- skid systems on these airplanes; and do whatever we can to get them to work with us on preventing this from happening again.it has been said that cessna is being 'tight lipped' about this. That is unacceptable and we should not allow this to continue. The manufacturer of an airplane should divulge all available information about any fleet wide problems that have occurred with this anti- skid system on the citation sovereign line.we had a similar issue in our other identical ce-680 just two weeks prior. They are four serial numbers apart.we have been flying these airplanes for several years without incident and both anti- skid systems fail within two weeks of one another.the cause is said to be a combination of bad valves and bad anti-skid controllers; yet the anti- skid controller they sent us for the first airplane repair was from another ce-680 (not ours) that had the same problem. It was tested and they could not duplicate the problem so cessna put it back into the system. The only reason we know it came from another 680 with the same issue is that it stated so on the 8130 form. Again this is totally unacceptable and it seems like there is a larger problem with the design of the anti-skid system in citations. I believe the FAA should conduct an investigation on this matter.

Title: A Pilot reports Cessna is being 'tight lipped' about incidences involving failures of the Anti-Skid Systems on Cessna-680 Citation Sovereign aircraft. During a recent landing using slight application of the brakes; he noticed a Master Caution illuminated with the 'AMBER ANTISKID FAIL CAS' message and a loud squeal/skid noise; the left main landing gear inboard tire was found flat. Bad valves and bad Anti-Skid Controllers were noted as recurring contributors.
