Retrofit Kit (applicable to serial numbers JSX0003 thru JSX0022).

Kit parts in-production and are estimated to ship by the 2nd quarter of 2019.

SubSonex Main Gear Up-Locks prevent “sagging” (partial deployment) of the gear during aerobatic positive G-loads. The system is automatic and the operating procedures in the cockpit are unchanged.

SubSonex Up-Locks have been in-use in Sonex factory prototype aircraft with frequent air show performances, exhibition and test flight operations since mid-2018. See our video of the locking mechanism in-action!

All new SubSonex Personal Jet orders under current pricing will include Up-Locks, and Upgrade Kits are available to existing customers.
