4 G1000 Continued Airworthiness
4.1 Airworthiness Limitations
The G1000 integrated cockpit is airworthy when installed and configured in accordance the STC issued
under FAA Project #ST3636WI-A. The Airworthiness Limitations section is FAA-approved and specifies
maintenance required under §§ 43.16 and 91.403 of Title 14 of the Code of Federal Regulations, unless an
alternative program has been FAA-approved.
The G1000 system possesses the following maintenance airworthiness limitations:
Every 2 years, replace all lightning protection 3.2 Amp slow-blow fuses. There are five total
fuses in the following locations:
•
Two fuses mounted behind the instrument panel, near the circuit breaker panel. Each fuse in
wired inline with a voltage suppressor.
•
Three fuses mounted on the field-fabricated lightning protection component block, which is
attached to the forward portion of the remote avionics enclosure. Each fuse is mounted to the
side of the block, and each is labeled.
Replacement consists of twisting each fuse holder cap counter-clockwise, removing each fuse and
replacing with a new fuse. For detailed drawings, see Section 2.5.
There are no other maintenance airworthiness limitations associated with this type design change. The
G1000/DA 40 Airplane Flight Manual Supplement defines all other airworthiness limitations.
4.2 Servicing Information
G1000 LRU maintenance is ‘on condition’ only. No component-level overhaul is required for this type
design change.
4.3 On Condition Servicing
‘On Condition’ replacement and/or servicing should occur when an item exhibits conditions, symptoms,
and/or abnormalities defined in Section 5 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 maintenance practices.
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
common sense and a thorough knowledge of the system. Use sound avionics
maintenance practices when working around or on G1000 equipment.
