See ATSB report BS/20010005,
"Investigation into Ansett Australia maintenance safety
deficiencies and the control of continuing airworthiness of Class A
aircraft".
The Australian Transport Safety Bureau recommends that the
International Civil Aviation Organization develop standards for
States of Registry to ensure that there are appropriate performance
measures for continuing airworthiness standards, that take into
consideration:
* the process defined in the standard
* a defined outcome that the standard is intended to achieve.
It is believed that the intent of the recommendation was
achieved by work which culminated in the 9th Edition (Amendment 98)
to Annex 8 -Airworthiness of Aircraft which became
applicable on 2 March 2004. The changes to Annex 8 included
restructuring Part II into four chapters, namely, Type Certificate,
Production. Certificate of Airworthiness and Continuing
Airworthiness with the intent of assisting States to understand
their responsibilities. ICAO Standards in these areas are high
level and do not prescribe the process or means by which a State
complies with the Standards, however, more detailed guidance
material has been included in these areas in the revised
Airworthiness Manual (Doc 9760).
