I was flying already weary C210s in the mid 70s. 50 years later they’re still tooling around (mainly) desert Australia with its strong thermals and subsequent heavy turbulence.
I’ll bet Mr. Cessna never designed the C210 to have so many hours and cycles put on it.
To answer the question… the C210 type is no more or less dangerous than any of its peers. However, certain, examples maybe because of too many airframe hours, poor maintenance and pilot abuse.
