Steak&Kidney_Pie,
I guess that depends on how you read what I wrote lol.
Yes FAR 23 is common, but because of the CJ3 (C25B) being over the 12,500lb mark it was certified under the Commuter category, which the lighter C525 models were not.
This had implications such as the additional requirements for a smoke detection system in the baggage holds, an annunciation to display if the emergency exit is insecure and a prohibition on takeoff with defective anti-skid function (among other requirements of course).
Whether this affected landing on paved runways or not I am not sure, and only suggested that the different regulations affecting the CJ3 compared to the smaller varients MAY have been a factor.

Chinchilla.
