GEA 71 Engine/Airframe Unit

Original GEA 71 Reinstalled
No software or configuration loading is required if the removed GEA 71 is re-installed. This does not
include units that were returned for repair as their software and configuration files are deleted during the
repair testing process. Continue to the return-to-service checks in Section 8.
Original GEA 71 Installed in Opposite Locations for Troubleshooting
No software loading is required if the original GEA units are installed in opposite locations (GEA #1 and
GEA #2 in opposite unit racks). Continue to the GEA 71 Test (Section 7.4.1).
New, Repaired or Exchange GEA 71 Installed
If a new, repaired or exchange GEA 71 is installed, the correct software and configuration files must be
loaded to the unit. See Section 3.9, and then continue to the GEA 71 Test (Section 7.4.1).
7.4.1
GEA 71 Test
On the MFD (normal mode), check the indication for each of the sensor or monitor inputs with the
aircraft engines off.
In general, verify all engine and system instruments show valid static normal values and markings, with
no red Xs or erratic indications. Reference Figure 7-4 for normal engine instrument markings (figure
may not reflect actual aircraft installation). If necessary, reference Sections 7.4.2, 7.4.3 and 7.4.4 for
additional tests to verify instrument readings.
