I taught a composite repair class to Duncan in Lincoln a while back and they come through Flightsafety occasionally. I've been to Dallas a few times for Turbomeca school down in Grand Prairie and of course Dolphin school quite a few years ago.
I retired in 2001 out of Miami. I was in New Orleans, North Bend and Savannah in between three tours in Miami. I'm in West Palm Beach now teaching helicopter maintenance on Sikorsky's and composite repair. Who are you with in Dallas? Nice pics of the old H3!
