first, my condolences to the family and friends of the pilot. this is going to be a bit harsh but is not meant to be judgemental, I just hope that it helps stop somebody else from making theses mistakes.
there are two many IFR accidents because pilots say, " i have done my six approaches ect and i'm current". yes, you are legal, but not current. as a 15,000 hour 121 captain those weather conditions still would make the hairs on my neck stand up. approaches down to mins are a serious game and should only be done by pilots that are more current than 6 approaches in six months.
the atc tapes show that this pilot was well behind the aircraft and weather conditions. he received multiple low altitude alerts from atc, that is the time to go around and go some where else.
weather mins. the approach mins for that ils is 7/8 and 927 feet, 300 feet above the ground. the current weather was 1/2 and vv2. both below mins. yes under part 91 you can "go take a look" but that really is not a good idea. 300 feet above the ground single pilot, looking for the runway is not a good place to be, and that's why in the 135 and 121 world you cannot "go take a look"
it saddens me every time i see an accident like this, we as pilots are doing a poor job at decision making skills, and CFI's need to do a better job of teaching these skills and dangers when teaching IFR students. there are a lot of lessons that can be learned from this accident, lets all look at it objectively and learn something so theses types of accidents don't happen.
