Do you think ATSB investigates every BOS and LOSA that they receive from AsA? And if they don't how would we know given that the list is only from BOSs and LOSAs investigated by ATSB.
That would be very disturbing GF that the ATSB would choose to not investigate a BOS/LOSA event, which by ICAO definition is a 'serious incident'. However the bureau has a notified difference that does allow them the option of not investigating
:
Reference:
AIP SUPPLEMENT (SUP) H12/11 DATE: 5 MAY 11
PG 65 Para 5.1.1
Australia may not institute an investigation into all foreign or
Australian-registered aircraft involved in serious incidents.
Decisions on whether particular serious incidents will be
investigated will depend on resources and the likely benefit to
future safety.
Even if the bureau was crazy enough or in such current disarray that they chose not to investigate a BOS/LOSA they would still be obligated under Annex 13 section 4.1 to fwd the occurrence notification to ICAO.
If they haven't done that...wweeell
that would be something the good Senators and ICAO would be extremely interested in!
GF if your interested here are the ATSB BOS/LOSA incidents from 2000-2006:
