Maintenance Intervals

Table 4-1 shows systems and items, installed by this STC, which must undergo tests or checks
at specific intervals. If the interval is shown in flight time as well as calendar months, the first
interval reached should be used as the limit.
The tolerance for inspection times is the same as that stated in 5-10-00 of
the Cessna Maintenance Manual applicable to the airframe.
The intention of Garmin is to align this maintenance program as best as possible with the
existing Cessna Nav III inspection program. For a complete description of the Cessna
inspection program, refer to the Cessna Maintenance Manuals listed in Table 1-1.
For equipment not listed here, refer to the G1000 Nav III Line Maintenance Manual.
