Safety Action

Summary

As a result of this investigation the Australian Transport Safety Bureau has identified a safety deficiency related to pilot training. The results of the investigation of this safety deficiency will be published on the Australian Transport Safety Bureau website.


As a result of this investigation on 9 March 2001, the Australian Transport Safety Bureau issued the following recommendations to the Civil Aviation Safety Authority.

 

R20010015

The Australian Transport Safety Bureau recommends the Civil Aviation Safety Authority consider revising Civil Aviation Safety Authority Safety Aircraft Survey Report 604 form to require a response date for acquittal of discrepancies.


CASA response to recommendation R20010015 dated 10 April 2001.

The ASR (Aircraft Survey Report) can be assigned either Code A, B or C.

Code A identifies a defect or damage to the aircraft, and requires that maintenance to rectify the defect or damage must be carried out before further flight. This acquittal requirement is very specific in relation to the aircraft operational requirements. However, if the Certificate of Registration (CoR) holder removes the aircraft from service, an actual acquittal date has no relevance. The requirement to perform the maintenance before further flight remains.

Code B is a direction under CAR 38(1) to have defects or damaged assessed and rectified as necessary. The Code B direction is used to bring a defect or damage to the attention of the CoR holder, the pilot or operator where:

- A defect or damage to the attention of the CoR holder, the pilot or operator where:

- The inspector considers the defect or damage to be minor, or;
The inspection carried out on the aircraft does not enable proper
determination if the defect or damage is major. In which case the C of
R holder, the pilot or operator is responsible to have an assessment
carried out to determine the true nature of the defect or damage, and
have appropriate rectification carried out. While the assessment needs
to be done prior to further flight, the rectification might not be
accomplished for some time in the future, where, for instance, the
defect is minor and falls within the provision of Permissible
Unserviceabilities.

Code C is used to give the C of R holder formal notification of a non-compliance with a requirement or condition imposed under the regulations and is judged, on the basis of the inspection, not to have an immediate adverse effect on safety. However, the matter is required to be assessed and rectified at the earliest opportunity.

As can be seen from the above discussion, it is often the case that an acquittal date cannot practically be imposed at the time of issue of the ASR. However, CASA is currently reviewing the ASR process to see how that process might be more closely monitored.


ATSB actions concerning CASA response to R20010015

The ATSB classifies this recommendation OPEN- MONITOR, pending CASA review of the ASR process.


As a result of this investigation on 9 March 2001, the Australian Transport Safety Bureau issued the following recommendations to the Civil Aviation Safety Authority.

R20010016

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 Survey Report ASSP 604 forms within the last 12 months.


CASA Response to Recommendation R20010016 dated 10 April 2001.

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.
