>Someone put out on the Teenie forum that if your N number was NX something, >then you did not have to put the EXPERIMENTAL inside the cockpit. >Does anyone know if this is true? I posted information here on this topic in Feb, 2002, where I mentioned that in 2007 the KR design would be 30 years old and builders would be eligible to apply the "NX" registration prefix in lieu of a passenger warning placard. Here's a snip from my post, as well as the text of the applicable FAR: ==================== 'Scuse my slip; it's FAR 45.22(b). It doesn't say you can prefix the registration number with an "X"... it always has to start with an "N" but under the provisions of this FAR it can be "NX..." and the large passenger notification "EXPERIMENTAL" at the entry to the cockpit can be dispensed with. Here's the text of the FAR, from the EAA Homebuilders' website: (b) A small U.S.-registered aircraft built at least 30 years ago or a U.S.-registered aircraft for which an experimental certificate has been issued under § 21.191(d) or 21.191(g) for operation as an exhibition aircraft or as an amateur built aircraft and which has the same external configuration as an aircraft built at least 30 years ago may be operated without displaying marks in accordance with §§ 45.21 and 45.23 through 45.33 if: (1) It displays in accordance with § 45.21(c) marks at least 2 inches high on each side of the fuselage or vertical tail surface consisting of the Roman capital letter "N" followed by: (i) The U.S. registration number of the aircraft; or (ii) The symbol appropriate to the airworthiness certificate of the aircraft ("C", standard; "R", restricted; "L", limited; or "X", experimental) followed by the U.S. registration number of the aircraft; and (2) It displays no other mark that begins with the letter "N" anywhere on the aircraft, unless it is the same mark that is displayed under paragraph (b)(1) of this section. ==================== Oscar Zuniga San Antonio, TX mailto: taildr...@hotmail.com website at http://www.flysquirrel.net
