Hey 'aroa'
I have heard it said, in the most 'hallowed halls' of 'Tiger Moth' knowledge, that the 'real' cause for that one, may have been a 'delamination' of the spar (s) due to the ageing of the 'animal based' glue holding said laminations...….
i.e. The 'slats' had nothing to do with it...……
And, being a 'DH-82A' owner, I am inclined to give it some credence...…
'Old' history now, and unable to be substantiated either way.....but...….
Cheers
