Even if the aircraft exceeded 171 knots, the normal engineering factor is 150% (also known as the "ultimate load limit"). So, the structure should have been able to hold together until at least Vne x 1.5 (for example 171knots x 1.5 = 256.5knots). If your aircraft tears apart right at Vne, then imagine how much damage you would be doing flying one knot below Vne. That's why there's normal an engineering factor of 150%.

However, if the structure was damaged it might not make it to 150% over, such as corrosion. I've found lots of corrosion in the wing tips before. It's possible. However, from my many accident investigations experience...it's usually a "change" that caused it. My Vegas odds are on improper wing tip modifications & or design. That's were I would start as an investigator.
