I have seen it in the POH, either in the safety notices or as a CAA supplement, limit is 26Kts i think. The best wind position to avoid a tailboom strike is to have the wind at 10 - 11 o'clock which means you have the blade rising on the left side of the A/C and at a high point as it goes over the tailboom and falling on the right side and at a low point as it passes the nose.

If the wind is from forward-left as you describe, the the blade advancing from the right side will reach maximum upflap at the 1 - 2 o'clock point, the retreating blade will reach maximum downflap at the 7 - 8 o'clock position. The tailboom is at the 6 o'clock position. You do the math
