2 Time Limited Inspection Requirements
2.1 General
The time limits stated are based on average usage and average environmental conditions.
The stated time limits do not constitute a guarantee that the item will reach the time without malfunction as the
factors mentioned before cannot be controlled by the manufacturer. Particularly, if an aircraft is operated in extreme
climatic conditions such as humid tropics, extreme cold, damp climates, or salt-laden conditions.
2.2 Time Limited Inspection Intervals
This data module gives a list of items that require inspecting or testing at different intervals. The intervals are
expressed in flying hours, calendar time, or landings.
To give the best utilization, each item listed in this section has been given an individual optimized periodicity. For
this reason, they are listed in a separate data module titled Scheduled Maintenance Checks Lists. Refer to AMM
12-B-05-20-00-00A-018A-A.
When a scheduled inspection is completed, the section should be reviewed and all requirements complied with.
3 Overhaul and Replacement Schedule
This data module lists component overhaul times and replacement times. The time limits for the components
are based on flying hours, calendar time or landings. The first overhaul and/or replacement of a component is
recommended to be done at the stated interval (permissible tolerances applicable). Based on the inspection results
at the end of the first overhaul or replacement task, the operator can use these results to determine subsequent
intervals applicable to the individual airplane or fleet operation, provided the operator has an approved condition
monitoring system. If such an approved monitoring system is not available, subsequent overhaul and replacement
of components should be done at the stated interval. Refer to AMM 12-B-05-10-10-00A-281A-A
The requirements of this topic may be accomplished by either:
− disassembly, inspection, assembly and test of overhauled components in accordance with the appropriate
Component Maintenance Manual or
− exchange parts from Pilatus Aircraft Limited may be purchased and installed. Compliance with one of these
two options is at the discretion of the maintenance center carrying out the time limit requirement.
Components not listed in the Overhaul and Replacement Schedule need only to be replaced when their condition
shows that replacement is necessary.
4 Supplemental Inspection Program
This data module gives the additional structural and component life limits and the supplemental inspections needed
for aircraft that have 25,000 flying hours or 30,000 landings or more and forms the Supplemental Structural
Inspection Document (SSID) needed to increase the life of the airframe. Refer to AMM 12-B-04-00-00-00A-000A-A
and 12-B-05-10-30-00A-280A-A.
