EASA and FAA-PMA parts

I was digging around for something and came across this on an obscure EASA site:

There is a Technical Implementation Procedure (TIP) for Airworthiness and environmental Certification, as a bilateral agreement between the FAA and EASA
EUTIP_rev6_pdf

Section 3.3.4 states the cases in which a FAA PMA part can be accepted by EASA, with the information that needs to be present in the Form 8130-3 (for example, a statement that the part is not a critical component).

I believe this is clear for new parts. However, my question has to do with when those parts are subjected to an inspection, repair or overhaul. I believe that a repair shop that carries out an overhaul, for example, on a component that is a PMA part, can’t add to the Form 1 or Form 8130-3 a statement such as “is not a critical component”. Only the part’s manufacurer can do it.

So, my question is: Are the requirements of the TIP out only applicable for new parts? What should a Form 8130-3 or Form 1 of an inspected/repaired/overhaul PMA part have, in order for us to be able to install it on an aircraft?

and the answer given was

Design changes under PMA concept are not considered under European rules nor by means of the bilateral.
If there is no design change linked to the PMA part (for instance the PMA part was produced under a license agreement), the part belongs to a design approved in Europe and the particular used part was already installed in a European aircraft, it can be installed if the part was maintained in an European approved maintenance organisation or if the part was maintained in a maintenance organisation located in the US and holding both FAA and EASA approvals. In this later case, the Form 8130-3 to release the part is called ‘Dual’ since the part can be installed in both US and European registered aircraft.
For maintenance provisions in regards to the Bilateral, do not refer to the TIP, but to the MAG instead.

Not sure I understand it, but it does sound like one of those combinations of requirements which nobody can satisfy in practice

Is a cylinder a “critical” part ? Hard to believe it isn’t.
Are Superior cylinders installed on EASA regs ?

Was reading through stuff and found this list of critical PMA parts according to OSAC (French ARC manager, document G -24 -00) :
Piston engines :
-Crankshafts;
-Connecting Rod Assemblies;
-Pistons;
-Wrist Pins;
-Cylinders;
-Cylinder Heads;
-Engine Mounts;
-Crankcase;
-Crankshaft Bearings;
-Valve Train (valves, valve springs, rocker shaftassembly, pushrods, camshafts);
-Fuel Delivery Systems (carburetors, injectors, fuel pumps).

At each ARC review, an up-to-date list of the PMA critical parts must be provided to the inspector with their limitations (time, calendar) and their CoC ( or whatever document is provided).

So it seems they are approved as long as listed and their limitations followed.
