Report Timing
Since some have asked.
We can expect a preliminary report after 30 days, as stipulated by ICAO Annex 13.
This first report will usually have nothing to say about causes, only statistical information about aircraft involved, persons involved, number of fatalities and injuries, timeline (as far as known), a narrative about what happened, and what has so far been investigated, and what is being investigated in the future.
Interim reports are published when something substantial and interesting to the public has been found, the final report takes however long it takes to tie up all loose ends.
Urgent other information, not necessarily interesting for the public, will be made available to manufacturers, operators, and relevant rulemaking bodies.
Reports must be made available in one of the ICAO working languages (English, Arabic, Chinese, French, Russian and Spanish). For high-profile accidents in non-English-speaking countries, English translations are often made available. In this case, the NTSB may provide a translation, but the original version will be authoritative.
