Do not use them unless you have no other option. Spent $3500 on a part they sent us that we where supposed to swap and send our old part back. The new part didnt work and we sent the exact same part back and they would not refund us anything. Of course they do not tell you there is no refund until they get there part back. All around bad experience and much better companies out there.
I had problems with my Piper Archers Pitot and radio systems while visiting the Fort Worth Area. Field Tech was recommended to me by a friend and I was really impressed with their work and the courtesy they extended to me. They went above and beyond what most shops do and they repaired my aircraft for a very reasonable price. For GA pilots when you see the nose of a King Air or Gulfstream sticking out of the shop you immediately think this is going to hurt and I am on the bottom of the list. Not so with these guys they give great service to anyone who pulls a plane in their hanger. I will take my airplane back to them for any avionics work I need in the future. Ask for Andy, he is a straight shooter and a hell of a pilot/instructor.
One stop shop, they have it all. Friendly staff and quality products. These guys lead the way.
If you need it they have it.
