The cooler used is the Stewart Warner 8406R. Apparently they never produced this kit. Anyway the question I have is this: There are other companies that have coolers,which are cheaper, that have cross-over numbers to the 8406R such as NDM part 20002A and Aero Classic 800075. Can these be substituted legally? what is the difference between PMA and FAA approved? Thanks Much , Thomas ____|____ /[ ]\ <:::::::::::::[<=o=>]:::::::::::::> o/ \o N74225 D73 ________________________________ Message 2 _____________________________________ Time: 05:55:02 PM PST US From: Subject: Re: TeamGrumman-List: Oil Temp Followup --> TeamGrumman-List message posted by: Hi Thomas, I am not an A&P and I sometimes get upset at the very officious replies to simple questions so here is my input. PMA means same as factory and you can install it with a log book entry. maybe owner or maybe A&P... see part 43 (think Concord battery) TC means that it is the factory part and can be installed with a log book entry. STC means that someone has done it before, the FAA has blessed it and you can install it with a 337 and be guaranteed acceptance. 337 with no STC means that you hope the FAA will approve what you have installed!
