Yeah, I'd check for signs of the glue joints failing, first.

If that's not the cause it needs to be asked whether there may have been damage from that previous accident. Has the wing flown since the previous accident? Has it endured at least the same amo unt of strain since that previous accident as it has on this flight?

Did you remove the covering and check where the most likely damage may have occured on the previous accident? I peel the covering off, and push and pull on everything possible with enou gh force that if anything were amiss, it would break, but if all was well, it wouldn't.Ï+
