Hi Mr 'arawa',
I could have said a lot more, but then I normally don't feed the 'ignorant trolls' who just sprout crap & like to see their name on the site.
I would think that EVERY DH-82A on the register has been 'rebuilt' - most of them more than once - and the 'old' problems of delaminating spars etc, are way behind us, one would hope!
Your suggestion is one of my thoughts also....
However, I'll leave all of that conjecture / speculation until more facts come to light.
And, if the go-pro is situated at the same site as in the 'Promo's', and intact, then there well might be an answer....
With respect,
Griffo
