No just any pilot or engineer can just walk in the ATSB's front door and start generating suitable reports, it takes years of experience - even for highly experienced pilots and engineers.
Oh, I don't know - it only takes about
two hours for an accident to be reported on PPRuNe before someone has posted:
- the METARs for three hours before and after the accident
- the TAF for the period
- a picture of the correct aircraft from airliners.net
- a link to the Jep chart for the approach
- a Google Maps link to the airport concerned
- the relevant ATC/Pilot radio recordings
- the route of the flight number in question on a radar tracking site, and
- the build number and previous owner history.
... and (most importantly) about three "most probable" causes
