FYI
" A blade strile is any incident during which a rapid deceleration of the drive system occurs due to conact of the main or tail rotor blades with the ground, water, snow, dense vegetation, or any other object sufficinent to cause any of the following:
Main rotor blades- Any impact damage to the leading edge or lower skin which exceeds the limits spcified in Chapter 62. Any skin cracks"
There are other criteria but not relevent to this incident based on the info on this forum.
The Question is did the drive system experience "RAPID DECELERATION" ?
and what constitutes it?
