Hi, I need to create a Flight test form for a PA-18 after the installation of some STC´s, looking for a valid reference i found a Flight test form in the Lycoming Operator manual (O-360), but this form is requiered only after a Top Overhaul. consulting with Piper they recommend me to use the AC 23-8C but this is for Airplane certification. Do you have any idea of a valid reference to créate a Flight test form or Operation check form?
