He just called and said Piper wanted about $325 for the SWITCH. I
looked in Aircraft Spruce and a non PMA switch is about $25.

Even $25 is way too much. As an A&P and practicing engineer, I would
never suggest that you simply pull the switch out, find one that looks
and functions the same (good sources include Mouser, Digikey, and
Newark), and install it. After all, that would not be an approved
part, so you would not be able to make the proper logbook entry.


Nor would this A&P IA, engineer, and avionics author ever recommend such an
approach. No siree, not me, not hardly ever. "Switch? What switch. It
must have been put on there before I bought the airplane."

Neither would this aspiring A&P replace the stall microswitch with one
from Radio Shack (switches drawer, left column, second from the bottom).

No way.

That reminds me of the movie "The Russians are coming, the Russians are coming!"
"... do not, under any circumstances, insert the ammunition magazine into the
mechanism ... and never move this lever to its full forward position to lock
the magazine in place ..." ;-)

I thought that was in "1941". Dan Ackroyd's character telling the hapless
homeowner what "not" to do with the anti-aircraft gun the Army was
positioning on his property.

We had a Mooney shop that figured out that Mooney gear actuator gears
are actually the same as some Cessna flap gears (the manufactor shipped
some to Cessna and some to Mooney). For about 3 years you couldn't get
Mooney gears so this shop grabbed a bunch of the Cessna ones. A friend
of mine bought some and about a month later got a call from the FAA in
Sacramento. They knew that Mooney gears could not be found and wanted
to know how he got his. The FAA was hoping most Mooneys would just be
grounded. Grounding the GA fleet would improve the aviation safety
record.

Manual trim isn't that bad but it seems a shame to lose a function
because of "attempted rape".

Piper made two different trim switches. One is a round switch with a
ridged slide. That switch is made by Mason Switch, but it is not one
that they keep in stock. You can order one from them, but it will run
you pretty close to the $325 that Piper charges for it. Most of the
cost is tooling set-up fees. If you have more than one made, the
incremental cost for the additional switches is quite small (on the
order of $10). One of the guys on the Cherokee Pilots Association chat
did this a while back and got 10 switches, which he sold at his cost.
There was recently several people on the Chat looking to buy switches,
so you might join if not already a member and get on the bandwagon.

The other trim switch they made was a custom assembly that contained a
pair of standard microswitches and a superstructure that holds a plastic
push button rocker. I don't know who made that one, and have not found
anything like it in any of the electronic catalogs.

Dave Wheeler on the Cherokee Pilot Association's Chat is putting
together an order for switches on Tuesday. If you are looking or one,
now is the time to sign up for CPA and get on the list.
