The cockpit of the XA42 has two seats in a tandem layout. The cockpit of the XA41 has one
seat. Special aerobatic harnesses are installed on all seats. The aircraft flight manual and the
log book are kept in a document bag on the left side wall.

The seats are made of a carbon-/glass fiber-reinforced composite. It is possible to remove
them for maintenance on systems that are installed below the seats (for example: the
control system, the electrical wiring and the smoke system). The seats are attached to the
fuselage structure with MS24693S274 screws. The top of the front seat is attached to the
instrument frame with MS35214-42 or AN526-832R8 screws. The front bottom of the rear
seat is attached to the fuselage floor with Velcro or with MS21083N08 nuts on male studs.
These studs are bonded on the fuselage floor.
To remove the seats:
1 Remove the screws.
2 Pull the seat up.
3 Pull the shoulder harnesses through the applicable holes in the top part of the seat.
(Exception for rear seats from SN 152 and on or after applying SB-XA42-2018-016).
