About Diamond Aire

Since 1996 Montana Diamond Aire Inc has been the only company dedicated to the Piper PA 23 series. As the exclusive holder of the majority of the STC’s in existence, we can provide everything you need from avionics installations to airframe/engine overhauls to complete conversions.

Montana Diamond Aire Inc is located at the Kalispell City Airport (S27) in Kalispell, Montana.

Our customers come to us from all parts of the country. While they are here they enjoy the discounted lodging rates that are provided exclusively to our customers by The Aero Inn. Nearby
Glacier National Park, Blacktail and Big Mountain Ski Areas provide scenic diversions as well as the wildlife that can be viewed on casual drives around the area.

In addition, we are only a 15 minute drive from Glacier International Airport (GPI) for those who fly in commercially.
