Page 4-2 G1000 / GFC 700 System Maintenance Manual - 300/B300 Series King Air
Revision 4 190-00716-01
4.2 Servicing Information
G1000/GFC 700 LRU maintenance is ‘on condition’ only. No component-level overhaul is required for
the G1000/GFC 700 installation.
4.2.1 On Condition Servicing
‘On Condition’ replacement and/or servicing should occur when an item exhibits conditions, symptoms,
and/or abnormalities defined in Section 1 of this manual. Replacement and/or servicing should be made
only after the technician troubleshoots the system to the extent determined necessary by using the
guidance in this manual along with common avionics maintenance practices.
IMPORTANT!
It is impossible to provide guidance for every conceivable failure scenario within the
scope of this manual. Every effort has been made to provide comprehensive
guidance for possible failures. The information in this document should always be
combined with sound aviation maintenance practices and a thorough knowledge of
the system. Use sound avionics maintenance practices when working around or on
G1000 equipment.
The remainder of this document is organized in the following fashion:
• Section 4.3 lists maintenance requirements related to the G1000 system.
• Section 6 gives instructions regarding the removal and replacement of physical G1000 equipment
and parts.
• Section 7 gives configuration and testing instructions to be accomplished if G1000 equipment or
parts are removed or replaced.
• Section 8 specifies system return-to-service procedures.
The beginning of Section 6 provides instructions to check the software part number and version of each
LRU before removing a unit. Procedures in Section 7 require the same check after LRU replacement and
software loading.
IMPORTANT!
All structural repairs associated with this installation are to be addressed in
accordance with the Hawker Beechcraft Structural Inspection and Repair Manual
listed in Table 1-2.
NOTE
After replacing or servicing electrical components near the GMU 44 magnetometers, the Magnetometer
Interference Test (reference Section 5) and Magnetometer Calibration Procedure (reference Section 7)
must be performed.
