No.

The Vne is what the manufacturer says it is and tests to. If the aircraft mfg. establishes the Vne as 200 KIAS and ensures that the aircraft has required structural and flutter margin at the service ceiling at that speed, then the Vne is in indicated airspeed for that aircraft as stated by the manufacturer.

If structural strength and not flutter margin is the limiting factor for establishing a particular aircraft's Vne, then the Vne would truly be based on indicated airspeed.

It all depends on the air frame and manufacturer.

@Carl, if the limit is 200 kts than it is 200 kts everywhere. At MSL up to as high as you can get. As long as you consider it TAS because IAS says nothing (except at lower altitudes where the IAS is almost equal to TAS).

There will always be debates, non believers and rocket scientists out there but a good article to read (if not already) is the one from the Vans website written by Ken Krueger on 'Flight high & fast'
