6 Equipment Removal & Replacement
This section describes how to remove and replace equipment in the King Air C90A/C90GT/C90GTi
associated with this STC. After removal and replacement, LRUs must be configured and tested as
described in Section 7.
CAUTION:
When removing and/or replacing any G1000 component, always ensure that aircraft
power is off. Unplug any auxiliary power supplies. Before performing maintenance, it is
required that the technician verify the LRU software part number and version number
matches the software configuration listed in the General Arrangement drawing, listed in
Table 1-2.
To check an LRU software part number and/or version, follow the procedure defined in Section 3.9.3.
If a faulty LRU is not reporting its software version and part number, check aircraft maintenance logs for
last software version loaded and verify against the General Arrangement drawing. The Software Manifest
page may also be used to check part numbers and versions.
The General Arrangement drawing allows alternate part number units to be installed with certain
hardware/software combination restrictions. Refer to the applicable “Garmin Equipment/Software List”
contained in the General Arrangement drawing for details.
