Pattern Altitude
What information or mis-information I've gained by osmosis. When a homebuilt is finished, it gets inspected and assigned some time to fly off and then has achieved some sort of certification. The annual condition inspection is supposed to, among other things, confirm that the plane hasn't been changed sufficiently to invalidate that certificate. Would an engine type change invalidate that certification? Theoretically, what if an plane built with an Lyc. IO-360 had been changed to some version of an Lyc. O-320. Would it have to be "re-certified"?. What if the kind of engine was changed, say a Rotax is changed out for a Subaru?
