Well after 800 hours of TW time I finally bolloxed it up
Taxiing along after landing at Corona California, seen a short pole and sign out the left window, panicked because I realized I was turning into parking to early jammed the brakes on with a 15k tailwind, nosed it over, prop shagged. First damage/ accident in 1100 Hours and 20 odd years of flying
Bugger bugger bugger bugger bugger bugger bugger and bugger again.
Sitting on a bench outside airport waiting on an Uber, would like to give myself a good beating.

Sorry to hear of your misfortune. I wish I could say I was accident free, but that is not the case. You just carry on a sadder but wiser aviator.
Sympathies piperboy. As for any required reports, NTSB 830 dictates. What happened in your case may or may not be reportable dependent upon the extent of the damage. See the second paragraph below for what constitutes "substantial damage". I hope you have her flying again soon.
Substantial damage means damage or failure which adversely affects the structural strength, performance, or flight characteristics of the aircraft, and which would normally require major repair or replacement of the affected component. Engine failure or damage limited to an engine if only one engine fails or is damaged, bent fairings or cowling, dented skin, small punctured holes in the skin or fabric, ground damage to rotor or propeller blades, and damage to landing gear, wheels, tires, flaps, engine accessories, brakes, or wingtips are not considered “substantial damage” for the purpose of this part.
§830.2 Definitions.
As used in this part the following words or phrases are defined as follows:
Aircraft accident means an occurrence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight and all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage.

My sympathies Piperboy. I flew the other half for a nice lunch to celebrate 30 years of accident free flying. Had a similar incident to yours and trashed the prop.
In my case the wooden prop was sacrificed and saved any other damage. Best of luck.

Pic of the damage, the van in the pic is the Aircraftspruce van that was picking me up to buy new tyres for the airplane, won't be needing them for a while I guess

Nice set of Q Tips you have there. 
It doesn't look like a sudden stoppage and you would have been at low power. You might get lucky.
I don't know the exact parameters but you may get away with a runout check on the crankshaft prop flange and, if that's within limits, just a new prop.

Sorry to hear it. I groundlooped a vintage taildragger a few years back and I must say it removed my enthusiasm for flying vintage aircraft pretty thoroughly. Haven't looked at a Tiger Moth the same way since.
Practically speaking whether it gets reported is largely in the hands of the airport management - if they choose to report it, it's reported. But either way a sudden stoppage requires an engine teardown, which hurts in the wallet and means you're grounded for a while.

This is the dirt where it hit, hard to believe it caused so much damage to the prop

Sorry you had a bad day Piperboy, But it does not look like too bad a day to me... I am confident that what 27/09 suggests will turn out to be the case.
You'll be buying a new prop, but I think many of us have had to do that
. Based upon my considerable experience with MT propellers, I suggest you consider theirs, if they have one for your aircraft.
As for your engine, I think you'll be breathing a sigh of relief before long...
And your pride? You're just in a different club with a bunch of us now! Welcome, 'just a bit more humble since!

Piperboy - Look on the bright side. You might have just started a new trend to "proplets", to reduce prop tip vortices, noise and vibration!

You have to be more careful with some types other than with other types! Some have very little clearance from the prop tip and the ground which means you have to be more careful over bumpy fields.
Another Gotcha point is leaving a tarmac runway to cross a grass field at an early untested point. There is often a marked hump on the edge points between grass field and runway.
Better to leave at such points column well back and at 45 degrees rather than head on as well as throttled back rather than powered over suspect areas
But you will get over it! Kind of reinforces the point that the landing isn't over until the engine is shut down

AD 2004-10-14 and Lycoming MSB 475C require an engine disassembly and some parts be replaced. The bent propeller is considered a major repair (AC 20-37E) and must be done by an approved prop shop. Depending upon age of the prop and their inspection, you might get by with only new blades ($9500) and keep the original hub.

My sympathies. I came very close once in the Chippy taxying downwind in a very strong wind. I had the stick forward so the wind was pushing on the 'down' elevator and pinning the tail down, but the rudder got away from me and was blown hard over. Having a touch of brake on for steering while taxying the full rudder deflection jammed the brake hard on on that side and the tail lifted.
I was considering (for an instant!) whether to pull the stick hard back and whack on the power to blow the tail down when it stopped rising, probably due to the forward stick position, and sat down on the tailwheel again. Nasty lump in the throat when that tail went up!
I once almost ground looped as well, having returned to the Chippy after a few years flying a Yak 52. I turned off the runway still going a bit too fast after the roll-out and instantly felt the tail step out. Full rudder and a hard squeeze of the brake handle stopped the swing almost before it started, but again, a nasty feeling when I felt it 'go'.
I hope your damage is limited to the prop. In UK I think it'd be a shock-load strip down regardless. When our Yak was landed gear up (not by me!) the wooden prop shattered to matchwood as it is designed to do to protect the gearbox and engine. That cut no ice with our 'take no chances' system. It was a full tear down (which, of course, revealed a perfect engine and gearbox).

Sorry to hear that. Don't beat yourself up about it, stuff happens. That's what we pay the insurance for. Could be a lot worse. Nobody hurt, and the aircraft is repairable.
grounded for a while.
