Kurt,
Sorry to hear about it. Nylon screws would have certainly prevented that[:-]

On the bright side this is a pretty clean break! Its actually good that the blind nuts were pulled through the block and not totally ripped the block out with it. That would have resulted in more complicated damage. The firewall and sheeting look unscrached too! Says a lot about this tough bird!

Looks like youre right on track getting her back on the flight line![8D]
