COMPARTMENT HATCHES
A number of access doors and hatches for different airplane systems
can be found along the fuselage.
The compartment hatches provide access for servicing the airplane
systems and equipment.
The under cockpit access hatch is located under the fuselage,
providing access to the fuselage pressurized compartment.
The forward electronic compartment access hatch is inside the nose
landing gear wheel well.
The rear electronic compartment access hatch is located on the rear
right side of the fuselage. This hatch provides access to the airplane
pressurized area containing the rear electronic compartment, rudder
autopilot servo, rudder control cables and electrical harness, stabilizer
electrical harness and elevators control cables.
A unlocked condition of any compartment hatch causes a single
caution message on Eicas. In addition, the MFD indicates the open-
hatch(es) condition in a graphical representation.
