I understand what you want to say but do not compare Indonesia KNKT with country Xxx (and I agree there are a few xxx out there ) but look at the NTSC report on the accident of the Sukhoi SSJ100 in Mt Salak in 2012 for instance . Go to pages 61 to 68 to make yourself an educated opinion of their expertise and independance. (You can download the report from ASN )
