Intercom installation

Post by jkvincent » Wed Jan 14, 2009 18:20

I'd like to permanently install a Sigtronics SPA400 (TSO'd) intercom in my Champ which has an electrical system.

Would this be just a Log Book entry or a (God forbid) Field Approval?

If its really installed in the airplane then believe that it would require approval.

Mount it with Velcro and run a power cable up to the intercom with a plug in connection. That way its not mounted full time in the plane and no paperwork at all needed.

Everything I have found shows it to be a minor alteration. I have installed them using the manufactures instructions and 43.13 as a guide. The aircraft equipment list and weight and balance will need to be updated and the electrical load computed.

If your Champ has a legal electric system, it just takes a 337 by the AP/IA or the avionics shop....whomever installed it! NBD! The velcro approach works too!
