Piper SB No 836 (alluminum wire replacement)

Strictly speaking, the change of wiring is a change to the type
certificate.

You could deem it a minor modification and do it with a log book entry.

You would be ok unless somewhere down the line someone wanted to debate
the point.

Then the $115 would look pretty cheap.

My service manual (page 4D1) states that the #1 aluminum wire can be
replaced by #3 copper by following procedures in 43-13.

No STC or kit needed, just get some wire and terminals and do it by the
book.

You *can* change the wiring per the SB836, but because the approved data
is the SB and maintenance manual, but may *only* use the materials
specified in the SB or maintenance manual.

Go ahead and try to find exactly the specified wire and particular
terminal numbers. Some of them are next to impossible to find,
especially in qty 1 each.

The Bogert cables are pricey. American Aviation has an STC kit that is
about $130, which went on my Cherokee over the winter while my engine
was being overhauled.

You could barely buy the wire and terminals for that much. #2 aircraft
cable is expensive and you need a lot of it for a PA28 with a rear
mounted battery.
