The Australian Transport Safety Bureau recommends the Civil
Aviation Safety Authority consider revising Civil Aviation Safety
Authority Safety Trend Indicator form to indicate organisational
non-acquittal of Aircraft Surveillance Report ASSP 604 forms within
the last 12 months.
In relation to recommendation R20010016:
Non-acquittal of an ASR within a particular time period does not
necessary reflect poorly on an operator. Consequently, for ASR
acquittal information to be meaningful, in regards to Safety
Trending, would need complex and prescriptive criteria to be
developed and followed by CASA inspectors in the field.
Depending on the outcome of the review mentioned in Para 2 above,
CASA would also explore what useful application that information
might have in regard to the Safety Trend Indicator.
ATSB Note: CASA has revised it's Aircraft Survey Report- ASSP
604 form to include a return portion with corrective action related
to the noted discrepancy. This then precluded the opportunity for
an ASSP 604 form non-acquittal.
