Randy,

You keep repeating these stats as if they mean something germane to this discussion. Are you implying LNC-2 pilots exceed Vne regularly?

I have two thoughts about these stats: 

First, without knowing the number of times the published Vne has been exceeded in LNC-2 aircraft, whether the airframe has been modified, the flight conditions, altitude, KIAS/KTAS, etc, this 'stat' means nothing. Anecdotal evidence is not data.

Second, the fact that Lancair hasn't issued a bulletin regarding flutter on a certain model of aircraft tells me the Vne chosen for it appears to be appropriate -- it says nothing about the prudence of exceeding it.

What this info says to me more than anything else is that most LNC-2 pilots have a healthy respect for the published Vne.

The stats are: Not one LNC-2 has come apart from exceeding Vne. There are no service bulletins from Lancair regarding high speed flutter on a small tail LNC-2.
