Expanded vs normal envelope Cherokee 180C

[Caramon13]

Plane is a 1965 Piper Cherokee 180C, serial 28-2919.

I found this in the type certification for the plane:

The Model PA-28-180, S/N 28-671 through 28-5859, may be operated to the expanded C.G. envelope:

(a) For S/N 28-671 through 28-3072 by the installation of P/N 65280-00 tube - Landing Gear Strut
Piston in accordance with Piper Service Letter 567 and in accordance with FAA approved Airplane
Flight Manual Supplement No. 2, dated September 14, 1970, for Model PA-28-180 (Piper Report
VB-261).

(b) For S/N 28-3073 through 28-5859 in accordance with FAA approved Airplane Flight Manual
Supplement No. 2, dated September 14, 1970, for Model PA-28-180 (Piper Report VB-261).


My question is, where would that information be properly documented? I went through all the logbooks last night, nothing in there that says this was installed. Would it be in the POH or W&B?

If it's not there, is there a way to VISUALLY verify it's been installed?

Thanks

If your cherokee 180 satisfies (b)[S/N 28-3073 through 28-5859] there's probably nothing in the log books because there's nothing to install. All you need to do is download the Supplement 2 (if you can't find it, PM me and I'll email you a PDF) and keep it with the regular documentation you keep in the airplane.

I keep 2 separate versions of the W&B forms (tablet & excel) one set for the "default" and the other set for Sup2. Example - for flight planning at home, I'll use my Excel spreadsheet and see which W&B works best for the flight.

On the other hand, if, by dint of the SN, your cherokee comes under (a) and there's nothing in the logs then it probably hasn't been done, because the shop would have needed to do it.
