If I remember correctly (The ATSB website is broken) the incident was caused by the wrong grade of bronze in a bushing in a fuel pump, which failed as a result.
I wonder what action CASA has taken to find out exactly how this occurred?
There are zillions of types of Bronze and its easy to "turn up" a little bushing. Trouble is, the loadings on aircraft parts are considerably higher than automotive use and the consequences of failure somewhat greater.
