The ATSB is still, in many ways, the model investigator and is world leading in its approach to accident and incident investigation. The NTSB is still into pilot error and single accident causes,
I hate it when ATSB comes up with "Significant Factors" thus leaving the reader to work out for himself the cause of the accident. Significant factors for example could be a crosswind, tired pilots, and so on but ATSB seem to carefully avoid any suspicion that the pilot may have stuffed up somewhere.
Years ago in the old Aviation Safety Digest days, the editor of that august journal was permitted to use his discretion and opine that the pilot did not use good airmanship where an obvious pilot stuff up caused the crash.
At least in those long gone times there was no pussy-footing around and plain English language was used. Now we see politically correct bureacratic weasel words with the prime aim to avoid under all conditions using anything which could be construed as the dreaded pilot error words. And then often we are none the wiser on what or who was responsible for the crash.
