While this is an important issue, it begs the question - how long before they make the same statement about legacy G1000's? These systems are 20 years old and it's not a $10K decision like a 430W, it's more like $150K. That will be a painful day. As a long-time semiconductor executive, I echo the earlier comment about the responsibility of a manufacturer of a long-lifecycle product to stockpile spares for extended maintenance. Garmin is playing in the same arena as other manufacturers of military-aerospace systems that require ongoing maintenance for 30 years or more. You don't ground A10 Warthogs due to lack of a few spare parts.
