I have reached the limit of my regulation digging and knowledge and need some guidance from real mechanic types:
I have an RV-9A with an O-320-E2D with 160hp ECI Titan Cylinder Assembiles. There is no 337 or STC because it doesn't apply to airframe and the HP increase was not greater than 10%, but there is a logbook entry saying all worked performed IAW Lycoming service manual and AC43-13.
Special Airworthiness was issued with 25hr Phase 1 due to certified engine and prop combo. Is it correct one of the following 2 options must be done?
I would assume there's more aircraft value in option #1.
Also...does swapping the originally certified -E2D Slick Mag with an E-MAG make the engine experimental anyway requiring removal of the data plate or may this be covered by "C" stamp also?
Thanks...Tim

- Keep engine "certified" by complying with Lycoming Service instruction and ensuring a "C" is appended to the engine serial number
- Make engine experimental and remove the data plate
