Are you serious? Maybe you should also stay away of any aircraft that had an AD in it's history?

If you read the AD, it states:

(h) After the effective date of this AD, do not install any Becker Flugfunkwerk GmbH AR 4201 VHF AM transceiver with an affected SN that does not have Change Index 02 or higher index number marked on it, unless it was removed to determine the SN or to check for Change Index 02 or higher index number..

So I think the concern is quite relevant. Even if you are VFR only, according to the AD, it should not be installed after the AD date.

The AD says good units must have "Change Index 2" or greater.
Where is this "Change Index" marking?
Anybody have an example?

Thanks,
Best Regards, Dave

Dave,
Mine has “Change Index 01� Printed just beneath the serial number.
