1.0 Maintenance Manual
1.1 Description
The Aero Twin Anti-Fog Window Liner Kit is intended to prevent condensation in the passenger
cabin windows by providing an insulating space between the outside cabin windows and the normally
warmer air inside the cabin. The window liners are constructed from 1/16” thick clear polycarbonate
sheet (Lexan →) with a foam seal strip located around the outer perimeter. The liners are installed
against the aircraft windows with the foam seal acting as a spacer. The existing interior trim is used
to secure the liner.
1.2 Installation / Removal
NOTE: These supplementary windows are not intended for installation on door
windows or cockpit windows.
This section describes general installation procedures.
1.2.1 Setup and Installation:
See Aero Twin, Inc. Document No. ATSW8-IM (Installation Instructions) for full
details on installation. In short, the molded interior window trim panels are
removed, the liners are placed against the corresponding windows with the foam
strip acting as a spacer, and then the interior panels are replaced. The interior
panels hold the liners in position.
1.2.2 Removal / Breakdown:
Window liner removal is accomplished by removing the molded interior window trim panels,
removing the liners, then reinstalling the interior panels. For long-term storage it is recommended
that the liners be covered to protect against direct sunlight, moisture and dust.
1.2.3 Weight and Balance
When supplementary windows are installed or removed, the aircraft empty weight and balance
must be updated to reflect the configuration change. Weights and arms for complete kits are
shown in Table 1.1.
