6 Equipment Removal & Installation
This section describes how to remove and replace equipment in the King Air 300/B300 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.
NOTE
After installation or maintenance of electrical components near the GMU 44
magnetometers (either tail or horizontal stabilizer locations), perform the Calibration
Procedure E: Magnetometer Interference Test (reference Section 5) and Procedure B:
GRS 77 or GRS 7800 and GMU 44 magnetic Calibration (reference Section 7).
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.
