11/21/2007



Hello Bob Nuckolls and other list experts, My friend wants to replace the 

two conventional 12 volt lead acid Gill batteries in his 24 volt system 

Beech Sierra with two 12 volt Concorde recombinant gas batteries.



I can find tables that shows the correct batteries, but also show that an 

STC (held by Wilco) is involved:

What is the proper procedure / FAA required paperwork / permission from STC 

holder, to make this battery switch?



Thanks.

   Call Wilco and I'm sure they'll be able to cite

   the process down to the last signature on your

   ship's paperwork. Generally speaking, the battery

   STC's are probably the simplest of "mods" to accomplish

   on a TC aircraft. I crafted a couple of STCs for B&C

   some years ago to put Genesis RG batteries (Hawker)

   on the smaller Cessnas and Pipers. When you buy

   the battery + STC it will come with the proper permission

   documents.
