3rd Window STC Modification Technical Description:

The modification requires the installation of Piper Cherokee aluminum structural channels and angles that rivet into place. The new windows may be cut from sheet Plexiglas or purchased. The window is held into place by interior trim angles which screw in place. On some models without a baggage compartment the windows are installed aft of the cabin divider. In this case, curtains may be added to enhance the appearance. On Piper Cherokee models with a baggage compartment the windows install forward of the cabin divider and provide improved visibility and appearance. In either case the airplane appears to be much newer and more expensive.
