I picked this up from BookFace: surprised that we haven't mentioned it on Rotorheads yet? 1800 hours on the blade,
This is what happened during our flight on the 7th of Sep 2012 on you way back from Gilgit(OPGT) to Islamabad(OPRN) on the 139. Experienced strong vibrations at 120 kts, reducing speed to 60 Kts did not help our case, hence had to force land in huripur, 10 mins short of OPRN. The first skin of the blade was pealed off. Did field repairs and changed the blade, flying back to base early next morning.
