If this was a GCAA investigation very simple, final report comes out 4 years later with inconclusive root cause. This is based on last few masterpieces produced by GCAA.
Unfortunately this is a Russia led investigation, so things work slightly different. Russia can submit their wish list to UAE. Final report will be based on the response. Or we will have two reports with different conclusions.
I am still kicking myself on how GCAA scores so high in ICAO audits, what merit ICAO sees in GCAA no one else sees?? Biggest mystery in modern aviation.
