Part 103 to E-AB

[Bill Berson]

I got a chance to skim over the doc and did not see where it said that. In fact, it specifically says:

15. AIRWORTHINESS CERTIFICATE (103.1(c).

a. If your ultralight has been issued an airworthiness certificate. YOU
cannot operate it as an ultralight vehicle under Part 103, An ultralight cannot
be operated interchangeably as a certificated aircraft and an ultralight
vehicle.


It does say it can be an E-A/B if it meets the major portion rule; if not it can be experimental-exhibition. To return it to a Part 103 ultralight requires surrender of any A/W certificate.

Sorry, I didn't intend to imply that it can be both at same time. It can't be both at same time.
But an ultralight can convert to EA-B with issuance of airworthiness certificate. Or EA-B can convert to ultralight with surrender of airworthiness certificate. It doesn't say how often you can do this conversion.
