Response text:

On 19 November 2015 the Civil Aviation Safety Authority (CASA) advised the ATSB that CASA ‘have now produced CAAP 5.23-1 (2) Multi-engine aeroplane operations and training, … [CASA] believe that this contains sufficient information to respond to the report safety issue’.

Current issue status: Adequately addressed
Status justification:

The ATSB notes that CAAP 5.23-1(2), dated September 2015, contains a comprehensive listing of reference material on page 4 and a new section on page 37, Section 6.17 En route engine/system failure training. The ATSB considers that the information provided in section 6.17, together with the content of the listed reference material, addresses the safety issue.
