On 7 October 2015, the Civil Aviation Safety Authority (CASA) advised the ATSB that,
CASA has considered the issue raised and is in the process of developing a policy and/or supporting procedure to address this. The procedure will give recognition to the relationship between the consensus standard for non-destructive inspection (NDI) AS3669 and reg. 2A of the Civil Aviation Regulations 1988, ensuring a minimum equivalent level of safety for alternate NDI procedures and approved maintenance data.
The ATSB has assessed the proposed safety action by CASA and considers that it should adequately address the identified safety issue. However, the ATSB will reconsider this assessment when the proposed safety action has taken place to determine if it remains adequate.
