I thought the cut-off for 2" high numbers was 1983 and post '83 3" numbers were allowable for "cruise speeds" <180 knots and 12" numbers required for cruise >180 knots.??

Placard
 
Mel,
Just for clarification.
Still need experimental 2 inch and other placard inside for passenger amateur built etc...

Thanks,

Boomer

The "X" in the N number replaces the 2" EXPERIMENTAL placard.
You do still need the passenger warning for the RV-4, but not for the -3.

If the design is more than 30 years old, a newer aircraft is considered a "replica" and meets 45.22(b).

Doesnt say anything about when it was designed but when it was built.

The Riverside FSDO made me remove the 2" N numbers from my March '83 registered LongEZ and install 3" high numbers. When I removed the O-235 and installed the O-320 in 1986 I fought with the FSDO regarding 12" high N numbers as we couldn't agree on the definition of "cruise speed". The FAA relented & the plane retained the 3" numbers as does the IO-360 powered '89 LimoEZ even though "cruise" is well in excess of 180 knots.

It's a bit early but I'm taking notes!

Me too, this is the first I have heard of this. Does this mean I can just put an X in the number without a new registration? I am liking this!

Only if your plane is old enough.
