A major milestone for our partner, Solo Aircraft Engines!

Today marks a significant achievement with the awarding of EASA Type Certification for the Solo SEDO engine.

This innovative, low-vibration engine variant has been developed over the past three years through a close collaboration between Solo Aircraft Engines and Ontrack Technologies, with Jonker Sailplanes as the launch customer for its JS2 and JS5 self-launching sailplanes.

This certification represents a crucial step forward in the certification journey of the JS2 and JS5 self-launchers, bringing both aircraft another major step closer to receiving EASA Type Certification, which are now anticipated in the very near future.

Congratulations to everyone involved in reaching this important milestone! A fantastic example of what can be achieved through technical innovation, perseverance, and strong industry partnerships.
