I didn't want to muddle up the pre 55 337 thread so I thought I'd take it up here.
Per Longwinglover:
The second caviat is "not contrary to regulatory requirements". In the posted 337, the data plate was changed. There are regulations saying you can't, TODAY.
Per the FAA's own rules and words, I believe Piper J3L-65, SN 5581, registered N32746 had its Type changed to a J3C-65 on Feb 16, 1946. I don't believe it can be done today.
Per the FAA:
(b) Except as provided in paragraph (d)(1) of this section, no person may remove, change, or place identification information required by paragraph (a) of this section, on any aircraft, aircraft engine, propeller, propeller blade, or propeller hub, without the approval of the Administrator.
[ (c) Except as provided in paragraph (d)(2) of this section, no person may remove or install any identification plate required by Sec. 45.11, without the approval of the Administrator.]
(d) Persons performing work under the provisions of Part 43 of this chapter may, in accordance with methods, techniques, and practices acceptable to the Administrator--
(1) Remove, change, or place the identification information required by paragraph (a) of this section on any aircraft, aircraft engine, propeller, propeller blade, or propeller hub;
Furthermore, another hangup seems to be the aircraft certified under different Type certificates. Leading some to believe the aircraft must stay under the TC it originally was certified.
If this was the case, One could not convert an AR7 certified Supercub to a 2A3 Supercub.
But this note in the AR7 TC proves otherwise:
(c) The Model PA-18A "150" (Restricted Category) is the same as the Standard Category PA-18A "150" except for minor design changes and can be converted to the Standard Category using the manufacturer's conversion instructions dated August 6, 1957. When operating in Standard Category, FAA Type Certificate Data Sheet No. 1A2 will apply.
The caveat in the case of the J3's is the "serial numbers eligible"
2325, 2327, 2339, 2340, 2342, 2344, 2345, 2347, 2349, 2351, 2355 and up;
2356-A and up; and 8277-1 through 8277-40.
If you have an aircraft in that S/N range, it is eligible to be re-certified under A-691.
