HC. The 76 blade defect was a manufacture defect that was accepted and release to service by SK.
The fold in the strip holed the spar when it had a lightning strike, it was returned to service after going to a blade facility in the UK, wonder who owned them????? We don't use multi section strips in the EBU any more.
HC, BB. The 76 blade had a production consession for a folded over abrasion strip edge. This created a point for the lightning to burn the spar. None of this was recorded on the log card. The blade inspection after the strike was done in the UK I seem to remember. In the same area of the country.
