We also have approval for STC SA04516AT which allows Lycoming A4A, A3A, A4N and A4M engines to be installed along with a Sensinich fixed pitch propeller. The upgrade is relatively simple. The airbox is the same as our Bold Warrior airbox and the exhaust requires a welded extension on the rear cross tube. The airplane becomes essentially a Cherokee 180 but retains the original cowl.

Please contact us for more information.
