The engine manufacturer did not require its manufacturing engineers to consult with the design engineers to ensure that design intent would be maintained when introducing manufacturing datums.
Rolls-Royce advised the ATSB that:
In January 2011, a revision to GQP [group quality procedure] ‘Manufacturing Technical Package’ was issued that provided greater structure and guidance for buy-off [manufacturing acceptance] between design and manufacturing personnel.
The ATSB is satisfied that the action taken by Rolls-Royce adequately addresses this safety issue and therefore makes no recommendation.
