As quick as some have been to suggest that this flight shouldn't have been attempted given the TAF, or that the approach(es) shouldn't have been attempted based on the AWIS, it's worth noting that two other IFR twins arrived without difficulty that morning - one a bit earlier and one about half an hour after the accident. Both reputable companies, both reportedly got visual comfortably above the RNAV minima. I'm not doubting that it was fluctuating and was rubbish when OZO arrived, but the TAF was nothing out of the ordinary for a tropical wet season day. There is also a suggestion that the aircraft may have only made one missed approach and that the accident was on the second attempt - doesn't change the outcome but it might change the tone of the conversation about how hard he had been trying to get in.
