In relation to recommendation R20010015:

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:

- 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 response:

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.
