Flying Bean, thanks for the update. That makes interesting reading!
The Australian Transport Safety Bureau (ATSB) has its final report available on its website. See occurrence 200405510. It does not come to any conclusions, so adds nothing further to everything above.

The crash is referenced on the NTSB site under WAS04WA015. There seems to be a problem with the NTSB site as every attempt to access the report results in the following message: “Sorry, we are experiencing a problem with the database.”
