Description
1 General
This data module describes the recommended Scheduled / Unscheduled Maintenance Program for the PC-12/47E
aircraft.
The current PC-12 maintenance policy (100 Hour and Annual Inspection Program as well a Progressive Inspection
Program (PIP)) is superseded by a revised maintenance program issued with Revision 19 of the AMM. This new
program increases the inspection interval and allows greater flexibility in scheduling maintenance to reduce the
number of inspections.
Chapter 5 contains a new Master Maintenance Plan (MMP), a revised Time Limited Inspection Requirements data
module and a number of inspection packages with defined intervals based on a combination of fight hours, number
of landings and/or calendar time.
Note
It is the responsibility of the owner or operator to make sure the times are monitored correctly.
Note
For the engine scheduled maintenance tasks, refer to P&WC Engine Maintenance Manual (EMM).
2 How to Transition to the New Maintenance Program
2.1 100 Hour and Annual Inspection Program
If you are on the 100 Hour and Annual Inspection Program, you must complete an Annual Inspection in accordance
with the AMM (at Revision 18) before you use the new maintenance program with the extended inspection
intervals.
2.2 Progressive Inspection Program
If you are on the PIP you need to complete the inspection program cycle (Phase 1 to 6) given in the AMM (at
Revision 18) as scheduled before you use the new maintenance program with the extended inspection intervals.
Alternatively, at the next scheduled inspection, complete the outstanding inspection phases.
3 New Maintenance Program With Increased Interval Extension
The new maintenance program has these sections:
− Time Limits
− Scheduled Maintenance Check Lists
− Scheduled Maintenance Check
− Unscheduled Maintenance Check.
3.1 Time Limits
This section consists of a list of time limited inspection requirements. These tasks do not fit in one of the predefined
scheduled inspection packages. Refer to 12-B-05-10-00-00A-018A-A.
There is no change to the Overhaul and Replacement Schedule and, the Supplemental Inspection Program.

UNCLASSIFIED 2019-11-19 Page 2

3.2 Scheduled Maintenance Check Lists
This section gives the details of the scheduled inspection for the aircraft. Refer to AMM 12-B-05-20-00-00A-018A-
A.
3.3 Scheduled Maintenance Checks
The scheduled maintenance checks gives the MMP and the scheduled inspection for different flying hours or
calendar time based inspection packages.
The Master Maintenance Plan (MMP) gives the list of all the Airworthiness Limitations (AL), Time Limits and
Scheduled maintenance checks by S1000D system, sub-system order. Refer to AMM 12-B-05-40-00-00A-000B-A.
For those operators that would like to repackage the task requirements, the MMP can be used as long as the given
intervals are not exceeded. Refer to AMM 12-B-05-40-00-00A-000B-A.
3.4 Unscheduled Maintenance Checks
This section gives inspection requirements which are necessary after a special or unusual circumstance has
occurred which may have damaged the aircraft. Refer to AMM 12-B-05-50-00-00A-018A-A.
4 Definition of Terminology
It is the responsibility of the owner or operator to make sure that the time intervals are monitored correctly.
If the interval is given as any combination of Flying Hours, Months or Landings, such as 600 FH or 12 Months, the
interval is understood as “whichever comes first”.
4.1 Flying Hours (FH)
Flying hours are defined as the total time between take-off and landing.
4.2 Months
The date on the aircraft data plate is used as the start time for all the calendar month intervals.
The subsequent monitoring procedure, for all the calendar time limited items after their initial replacement or
inspection will be in elapsed time or installed time. This is given with each component interval in these data
modules, refer to AMM 12-B-05-10-10-00A-281A-A and AMM 12-B-05-10-20-00A-281A-A
Elapsed time is the time interval since manufacture of the component.
Installed time is the time interval since the installation of the component on the aircraft.
For calendar based time limited items, the inspection requirement is to be done no later than the last day of the
month of the calendar interval given. This is also applicable to all the subsequent calendar time limited inspection
requirements.
4.3 Landings
All landings of a flight including the final landing; touch-and-goes; full stop landing with a follow on take-off in the
same flight.

5 Permissible Tolerances
The following paragraphs outline the permissible tolerances that can be applied to the interval of the tasks listed in
the Time Limits and Scheduled maintenance sections. The tolerance is not cumulative.
It is the responsibility of the owner or operator to make sure that any maintenance interval extension is accepted by
the local Airworthiness Authority of the country of registration of the affected aircraft.
The owner or operator is responsible for complying with all national regulations.
5.1 Flying Hour Based Intervals
The tolerance permissible for the flying hour based intervals is ±10%, but not more than 500 FH.
5.2 Calendar Time Based Intervals
The tolerance permissible for the calendar time based intervals is ±10%, but not more than 6 months.
The subsequent monitoring procedure for all the calendar time limited items after their initial replacement or
inspection, will be in installed or elapsed time. Each task with a calendar time is understood as installed time unless
stated as “elapsed”. This applies to tasks in Chapter 4 and Chapter 5.
5.3 Landing Based Intervals
The tolerance permissible for the landings based intervals is ±10%, but not more than 500 landings.
5.4 Examples
If you do an inspection inside the permitted tolerance, the planned inspection times do not shift. Two examples
have been provided for reference:
− The 300 FH inspection package can be accomplished any time between 270 FH and 330 FH (±10% or ±30
FH). The next inspection is still due at 600 FH (±30 FH). The inspection intervals do not change
− The 12 months inspection package can be accomplished any time between 11 months and 13 months (±10%
or 1 month). The next inspection is still due at 24 months (±1 month). The inspection intervals do not change.
If you do an inspection earlier and outside the given tolerance, then the planned inspection time will shift, examples
shown below:
If you do the 300 FH and the 300 FH / 12 Months inspection packages earlier and outside the given tolerance, for
example at 150 FH (2 months of operation), the inspection interval shifts. In this case the following inspection is
due at 450 FH (6 months of operation) with a ±10% or ±30 FH tolerance since only the 300 FH and the 300 FH / 12
Months inspection packages are due. However, the next inspection would then be at 600 FH (8 months of
operation) where only the 600 FH and the 600 FH / 12 Months inspection packages are due and as a result, ±10%
or ±60 FH tolerance can be applied. If the operation continues like this, at 1800 FH (24 months of operation) the
600 FH, 600 FH / 12 Months, 1200 FH / 12 Months and 2400 FH / 24 Months inspection packages will be due with
a ±10% or ±60 FH tolerance. The tolerance for the inspection is always driven by the inspection package that is
due with the lowest interval. The tolerance can be calendar time driven, if the inspection package calendar time
interval is reached first.

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.
