Kasper and BLA82,
Just tone it down a little. Turing what could be a useful discussion into a slanging match wont lead anywhere. The report, if the data in it is accurate, isn't good for Jabiru but the report may not tell the full story either.
Kasper, You suggest that placing a life limit on the components that fail is a suitable outcome but given the failures in the histogram below wouldn't that mean that the through bolts would need to be replaced every 100 to 200 hours give or take to be reasonably certain. Is that realistic?
Edit, My post #6 above referenced figure 10 but it is now too late to go back and edit it. . It should have been figure 6 on page 15.
