Why Upgrade at Silverhawk?

Silverhawk Aviation has installed more upgraded engines in King Airs than any other single location in the world. Not only that, we have developed an STC to install PT6A-135A engines in King Air 90s. Installation and rigging is critical to optimizing the performance from your new engines. We have the knowledge and experience to deliver your King Air on time and squawk-free.

If you have any questions or would like an evaluation for your specific situation, please give us a call.  We will be happy to provide a demonstration with a 90 or 200 series King Air operating with any of the upgrades you would like to consider.
