Can an a&p remove/reinstall xpndr after testing?

I assumed the aircraft this thread pertains to does have an MMEL, could be wrong, haven't checked.
It matters not if there is an (M)MEL or not. A non-A&P has no authority to return an aircraft to service after he removes the transponder.
 
To do what??
5.81 General privileges and limitations.
(a) A certificated mechanic may perform or supervise the maintenance, preventive maintenance or alteration of an aircraft or appliance, or a part thereof, for which he is rated (but excluding major repairs to, and major alterations of, propellers, and any repair to, or alteration of, instruments), and may perform additional duties in accordance with §§65.85, 65.87, and 65.95. However, he may not supervise the maintenance, preventive maintenance, or alteration of, or approve and return to service, any aircraft or appliance, or part thereof, for which he is rated unless he has satisfactorily performed the work concerned at an earlier date. If he has not so performed that work at an earlier date, he may show his ability to do it by performing it to the satisfaction of the Administrator or under the direct supervision of a certificated and appropriately rated mechanic, or a certificated repairman, who has had previous experience in the specific operation concerned.

(b) A certificated mechanic may not exercise the privileges of his certificate and rating unless he understands the current instructions of the manufacturer, and the maintenance manuals, for the specific operation concerned.

You only need them to do what they are rated to do, the common A&P is not rated to do transponder tests
Way to repost 65.81, Tom.

I said an A&P could/might be able to (perform the transponder test) you say "the common A&P can't"... we agree.
 
Lol, it takes no certificates to remove something from the airplane. However, it takes an "appropriately rated person" to return that aircraft to service afterward...

What if your nifty transponder has the encoder built in? Lol... Nuances...

Not susre why that makes a whole lot of difference. An owner-pilot can't RTS in any case. If you remove the static line, you may need a different repair station to cert things for IFR after you do it.
