Unveiling the CIS Navajo Chieftain

The Piper PA31-350 – CIS Navajo Chieftain

A new chapter begins for the Capt. Iceman Series.

We’re excited to share the first official preview of our next aircraft add-on for the X-Plane 12 platform: the CIS Navajo Chieftain.

Following the strong support for the CIS Seneca II and CIS Seminole, we’ve been working behind the scenes on something larger, more detailed, and more ambitious. The Navajo Chieftain represents the next evolution of the CIS (Capt. Iceman Series) philosophy: high-fidelity aircraft with uncompromising detail and a focus on authenticity.

Although the project remains under active development, today we’re revealing a small glimpse. Below you’ll find early previews of the work-in-progress 3D cockpit and exterior model. These images reflect live development — many details will continue to be refined as we progress.

Our vision for the CIS Navajo Chieftain is clear:

• Capture the power, presence, and handling of the PA31-350

• Deliver an immersive, high-accuracy twin-engine experience

• Build on the realism and depth that fans of the Capt. Iceman Series expect

We are not announcing a release window yet. This is simply the first teaser.
More updates, screenshots, and development showcases will follow as the project matures.

Thank you to everyone in the X-Plane community for supporting the Capt. Iceman Series and for the incredible reception of our previous releases.

Stay tuned — the next CIS aircraft is on its way.
