6. Equipment Removal & Installation
This section describes how to remove and replace equipment in the King Air 300 Series
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 1-1.
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, GRS 7800, or GSU 75B and GMU 44 magnetic
calibration (reference Section 7).
To check an LRU software part number and/or version, follow the procedure defined in Section
3.2.3.
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.
