General Arrangement of the Floor Covering3. Component Description
A. The floor covering gives passenger-comfort, soundproofing and is the protection for the floor panels and the floor structure. The floor covering is slip-resistant and made of fire-resistant material.
There is:
There is:
- The textile floor covering (TF) in the passenger area
- The textile floor covering (TF) / non textile floor covering (NTF) in the utility (wet) area.
B. Passenger Area
The floor of the passenger area in the cabin has pieces of textile floor covering on it.
The floor of the passenger area in the cabin has pieces of textile floor covering on it.
(1) Seat-Track Area:
Plastic covers are installed on the seat tracks. They make an overlap on the carpet and hold the carpet edges. The plastic covers are installed to give a smooth surface to the carpet at the seat tracks.

(2) Floor-Panel Area:
Double-sided adhesive tape or dispersion-adhesive attaches the textile floor covering to the floor panels. The double-sided adhesive tape is installed around the outer edges of the textile floor-covering pieces. The dispersion-adhesive is on all of the bottom surface of the textile floor covering.
Also all floor-panel cross-joints have double-side adhesive tape on them.

Also all floor-panel cross-joints have double-side adhesive tape on them.
The tape is installed:
- In the seat area 300 mm (11.8110 in.) apart
- In the aisle area 100 mm (3.9370 in.) apart.
(1) The floor of each cabin utility (wet) area has a cover of textile floor covering (TF) and/or non textile floor covering (NTF) . Floors in the galleys and near the passenger doors have usually a cover of NTF. The floor panels of the utility (wet) area have a layer of Adhesive Foil (MYLAR). This gives protection to the floor structure from liquids that can cause corrosion. Adhesive film attaches the floor covering to the floor panels. There are cut-outs for the floor attachments of the cabin furnishings. The edges and the cut-outs of the non textile floor covering are sealed with sealant.
There are different procedures to close the gap between the NTF sections:
There are different procedures to close the gap between the NTF sections:
- Sealing procedure
- Welding procedure.
(2) Utility (wet) area zone:
Areas that are frequently in touch with liquids are defined as wet areas and these are:
Areas that are frequently in touch with liquids are defined as wet areas and these are:
- Door entrance area with a minimum of 2 frame bays forward and aft of the door
- Galley areas with a minimum of 1 frame bay forward and aft of the galley outline
- Lavatory areas with a minimum of 1 frame bay forward and aft of the lavatory outline.
Utility (wet) areas have a cover of Adhesive Foil (MYLAR) -full floor width in transverse direction- .
(a) Seat-Track Area:
Corrosion inhibitor spray is applied to the seat tracks in (wet) areas . In areas of all seat track length under the Adhesive Foil (MYLAR), the seat tracks crowns are filled fully with corrosion preventive compound. Spacer-strips are installed on the seat tracks to give protection to the corrosion preventive compound.

(b) Floor-Panel Area:
The Adhesive Foil (MYLAR) is attached to the floor panels. This is a moisture barrier and gives protection to the aircraft structure from liquids. The (MYLAR) foil has an overlap of each other by 50 mm (1.9685 in.). Adhesive film attach the NTF to the (MYLAR) foil. Adhesive double-sided tape attaches the TF to the (MYLAR) foil.

(c) Joint Strips:
Stainless-steel cover-strips are installed across the aisles to cover the joints between the textile and the non textile floor coverings. The attachment screws are installed with anti-corrosion paste.
