Main Exercise
Purpose: The purpose of these lessons are to learn how to
do maintenance planning based on calendar intervals and/or operational parameter
intervals.
Purpose: The purpose of this exercise is to create a simple daily
inspection routine. To reduce administrative time, it
is decided that maintenance tasks should not be created for this daily routine. This
inspection is included in the Maintenance Code called nXDAY - Daily Check.
Prerequisites: Instruction number n072112 has been
pre-registered and is connected to this maintenance code.
Windows:
Maintenance Plan
Steps: To complete this exercise, perform the following
steps.
- Open the
Maintenance Plan window.
- Query (F3) for your Maintenance Program 10n, Part
Number X747-900 and Maint Group n.
- Click the
Intervals tab (This check does not use any Operational
Parameter)
- Create new record (F5) and specify Maint Code nXDAY - Daily Check.
- Specify Calendar Interval 1 day, check the Recurring Calculation
check box and set Recurring Cal Interval to 1 day.
- Set Days Forewarning to 1 day and Duration Workshop to 0.5 hours.
- Set Calculation Rule No Calculation (to
avoid the creation of daily maintenance tasks) and cycle No Cycle.
- Optionally, you can enter additional information
on the interval maintenance in the Task Remark field. When a task is created for the
interval maintenance, this information will be transferred to the Task Remark
field of the corresponding task record on the maintenance order.
- Save the information (F12).
- Select the record just entered, right-click and select Instructions
per Maint Code to verify that the instruction and the maintenance
plan are linked together.
Purpose: The purpose of this lesson is to learn how to
define an interval based A-check for your A/C. This check should be executed
first time at 100 Flying Hours or 50 Flying Cycles and should be repeated with
the same intervals or at least once every 3 months. You
accept a +/-10% interval tolerance. You want to have 7 days forewarning on
A-check tasks. Total time in workshop for A-check is expected to be 2 hours.

Interval to 3 months.
- Select the Recurring Calculation check box and enter identical intervals
for the recurring plan.
- Select the Use Tolerance check box and set Tolerance to +/-10%
respectively.
- Specify Days Forewarning to 7 and Duration Workshop to 2 hours.
- Set Calculation Rule to Inspection and Cycle to No Cycle.
- Optionally, you can enter additional information
on the interval maintenance in the Task Remark field. When a task is created for the
interval maintenance, this information will be transferred to the Task Remark
field of the corresponding task record on the maintenance order.
- Save the information (F12).
- Select the row just entered and create new record in the lower part of
the window.
- Specify Oper Param FCYC and set Maint Interval and Recurring
Interval both to 50.
- Save (F12) and verify that upper and lower tolerances for flying cycles
are calculated according to what was specified above.
Purpose: The purpose of this lesson is to learn how to
define an interval based A-check for the Nose Landing Gear. This check should be executed
every 50 Flying Cycles or 100 Flying Hours, or at least once every 3 months. You
accept a +/-10% interval tolerance. You require 7 days task forewarning and time
in workshop is estimated to 1,5 hours.

for the recurring plan.
- Select the Use Tolerance check box and set Tolerance to +/-10%
respectively.
- Specify Days Forewarning to 7 and Duration Workshop to 1.5 hours.
- Set Calculation Rule to Inspection and Cycle to No Cycle.
- Optionally, you can enter additional information
on the interval maintenance in the Task Remark field. When a task is created for the
interval maintenance, this information will be transferred to the Task Remark
field of the corresponding task record on the maintenance order.

- Select the row just entered and create new record in the lower part of
the window.
- Specify Oper Param FHR and set Maint Interval and Recurring
Interval both to 100.
- Save and verify that upper and lower tolerances for flying cycles
are calculated according to what was specified above.
Purpose:
In this exercise you define a maintenance plan
for the C-check Overhaul of the Nose Landing Gear. The C-check is planned at every 150 Flying Cycles (with
+/-10% tolerance) or 300 Flying Hours. The C-check Overhaul of NLG means that it has to
be replaced, and therefore the C-check also creates an replacement of the Nose Landing Gear. You want 14 days forewarning of C-check tasks which require about
8 hours in the workshop.
