(1) electronic equipments are located in a compartment below the cabin floor aft or the nose gear. This electronic equipment compartment is accessible on the ground through a door in the lower fuselage. If necessary, the compartment can be reached in flight through a floor panel In the forward part of the passenger cabin. Modification and troubleshooting are simplified through use of easily removable shelf assemblies.
