Thanks Blakmax for the reassurance about loads and disbonds. As I mention before the samples taken showed two types of failures.
1) There is adhesive and core impression on the outside skin. No adhesive on core cells.
2) There is adhesive on the core cells and only random areas or no adhesive on the outside skin. There is just a slight core impression in the areas of random adhesive.
It appeared to me that there maybe should have been an additional layer of unsupported film adhesive applied during layup particularly in the curved areas.
Anyway I'll leave it to the composite experts at Agusta to sort out their process woes.
And YES the replacement booms are under warranty even though some only last about 2 days before they disbonded as well.
The 139 is a good A/C and as with all new A/C has some growing pains. Luckily for us history dictates these pains get sorted out fairly quickly and I'm sure we will see a new improved Tailboom Assy sooner than later.
