1.3 Inspection:
The liners should be visually inspected annually or any time they are removed during airframe
scheduled maintenance. Check for cracks and general condition of sheet material. Confirm that
the foam seal strip is in good condition and is securely attached to the window. When inspecting
installed liners, confirm that liners are centered over the aircraft window. If the foam seal strip is
readily visible from inside or outside the aircraft, the liner should be repositioned.
1.4 Repair:
Small cracks found in the liners are to be serviced by stop-drilling as described in AC 43.13-1B
chapter 9. It is recommended that the drilled hole be sealed with a drop of clear silicon to retain
the insulating characteristics of the liner.
Cracks which extend 2 inches or more from an edge, or which result in the separation of a piece of
a liner, are cause for replacement of the entire liner assembly.
Scratches can be polished out using commercially available polishing compounds compatible with
Lexan.
Damaged foam seal strip can be replaced, in full or in part, using Cessna P/N P860037 seal strip.
Do not substitute materials when replacing damaged window liners. Refer to the Illustrated Parts
List for correct part numbers and contact Aero Twin, Inc. at (907) 274-6166 for replacement parts.

Window liners can be cleaned using accepted methods for cleaning aircraft glazing:
• Rinse using lukewarm water; wash gently with mild soap or detergent and lukewarm water,
using a soft cloth or sponge. DO NOT SCRUB or use brushes or squeegees.
• Rinse again. Dry with a soft cloth or moist cellulose sponge to prevent water spotting.
