Fairly strong. A bird isn't too big a deal. Clipping trees (which happens quite often...and recently, actually) will usually destroy the tip caps but the blades do okay. I've taken a soda can through the arc on a ship(non-event, left some green on the blade from the paint on the can) and a kids baby blanket through the arc. Fortunately, the baby blanket ripped up and some of it went back out while the rest of it blew down onto the ground after a few passes from the blades. We couldn't shut down until a couple hours later, but everything was fine when we did.
1) Had a SEAL team drive their Hummer into the rotor arc to load some stuff (while shutdown of course). They had a .50 pinned pointed upwards and destroyed a tip cap, trim tab, and about 6" of blade. Pulled up into a hover later to see if the bird was stable enough to fly back to Mx and you couldn't tell the difference.
2) Destroyed two tip caps when we hit some trees on the edge of a river, didn't even know it till we shut down.
3) Heard about a 60 losing TR authority while conducting HA/DR in Pakistan around '05-'06. They kinda slid down the side of the mountain and took some softball sized rocks through the arc...flew that one home too.

The ole Sikorsky Hedge trimmer is pretty tough. I know a couple of guys who have lost tip caps.
PhrogLoop can probably provide better stories, but I've heard of Phrogs taking messenger lines for the RAS through the arc and rappel lines that have gotten wrapped up on the pitch change rods (or links or whatever the phrog called the connections from the swashplate to the blades).
H-60 tip caps might as well be sacrificial (except for the part where the pilot gets in trouble and the fact that replacing them takes some effort and an FCF).
Rotor blades in general can survive some pretty amazing hits. The most extreme case I can think of was a Bell 206 hitting high tension powerlines (the big kind that come out of powerplants to power a whole city). Granted, those blades were a writeoff afterward but immediately following the wire strike they held on long enough for the helo to land (as opposed to crashing). Anecdotal, but impressive.

Do you even know what a write-off is, Kramer?
BTW, how in the fuck does a rap rope get all the way up in the rotor head?
Brett
The case I know of the rope wrapping around the aft head resulted in a class "C".
For Brett, the HAC was a known issue - it wasn't even the worst incident he had that FY.
My passdown sea story knowledge of it has the RAS event occurring off of USNS Mt Baker. The Phrog happened to be flying between the two ships before the RAS when a deckhand popped off a messenger line earlier then expected. The line went into the rotor arc and tightened up around the rotor systems.Do you even know what a write-off is, Kramer?

I still have no real clue how the rappel incident happened. I've rappelled guys a couple of times and the line has never made a move towards the rotor.

"You can't make this shit up..."
I was going to say the same thing! Good to see a P-8 with the old AIRTEVRON One colors on it.
That's why living OCONUS is so nice. Between all the TAD and govt travel, I have elite status and tons of miles. Those traspac flights are MUCH mo better in Business Elite/first.
Well, that's one way of looking at it.
Damn that thing showing up in your rear view mirror is what nightmares are made of.
