I'm trying to understand the Light Sport Pilot rules as they apply to EA-B, specifically lifetime changes.
As I understand, the gross weight must be under 1320lbs and have remained under 1320 for the aircraft's entire life (this disqualifies some Ercoupes). I'm wondering if the lifetime requirements apply to every factor. Namely, if the aircraft has an in-flight adjustable prop installed, does that permanently disqualify it from Light Sport Flying, or can you just swap the prop for a fixed pitch and fly it Light Sport?
