STC Timeline

We are constantly adding aircraft to this list, it is not all inclusive. Approval timeline is determined by the FAA, we have no control over this and will try to keep the timeline updated to the best of our ability. If you have an aircraft not listed, please reach out to us at sales@earthxbatteries.com and let us know what model you have so we can consider it on our STC list to pursue.

Also note that WHERE the battery is installed makes a difference to the FAA (AFT or FWF). Currently submitted STC pending approval is batteries located AFT of the firewall. If the battery is located in the engine compartment, this will come later this year.
