Overhead Stowage Compartment ** ON A/C NOT FOR ALL
The overhead stowage compartments (OHSC) have a box structure and are of different lengths:
- spacer
- 1-frame pitch
- 2-frame pitch
- 3-frame pitch and
- 4-frame pitch.
Each OHSC has:
- one or more doors with a handle/latch assembly for each door
- a handgrip along its length
- hinge mechanisms that attach the door to the OHSC
- a gas filled damper strut on each hinge mechanism (spacer OHSC only on one hinge) for a controlled door operation
- upper attachment brackets
- lower attachment brackets.
- mounting rails for the installation of the passenger service/information unit (PSUI) and the emergency oxygen container.
Brackets connect the OHSC to each other.
Brackets and turnbuckles attach the OHSC to the fuselage structure.
Cabin temperature control sensors are installed between the OHSC with reference to the cabin layout.

The Overhead Stowage Compartment (OHSC) XL bins with more volume and payload have a box structure with different lengths:
- 4-Frame "plus"
- 4-Frame "minus"
- 1-Frame "plus"
- 1-Frame
- 2-Frame
Each OHSC has:
- One or more doors equipped with 2 adjustable hinges and 1 latch for each door
- A maintenance hatch with the one connector ATA92 interface on top
- An under-bin light
- Illumination units lateral and on top Cabin LED Unit (CLEDU)
- A rail
- Cabin air outlet
- Ceiling support brackets
- Attachment points to A/C structure (X-/Y-tierods, Z-attachments)
- Bin to bin connection through inter-bin connecting plate
- As a 4-frame variant a stiffening device (O-Frame) in the middle of the bin
- Mounting rails for Passenger Supply Channel
- 2 covers installed on the bottom of the bin (inboard/outboard lateral panel)
- If requested through cabin layout (Ref. AMM D/O 21-63-00-00) - a temperature control sensor, which is installed between 2 bins (maximum at 3 positions inside the cabin).
