Maintenance Program Development MPD Presentation: Layout – Threshold & Interval
SAMPLE THRESHOLD : ST SAMPLE INTERVAL : SI 100% THRESHOLD : T 100% INTERVAL : I
Page 122
Maintenance Program Development MPD Presentation: Focus on Threshold & Interval Commonly used threshold/interval units:
Usage Parameters intervals
DaYs, MOnths, YEars, Flight Hours, Flight Cycles, Equipment Operating Units
Letter intervals (1A, 2A, 4A, 1C, 2C, 4C, 8C)
A = X FH
C = Y MO
e.g. In A330 MPD
X,Y varies from one MPD to another. A = 800 FH & C = 24 MO / 10000 FH
Starting point for calculation of the due dates or times of maintenance tasks:
First Flight (FF) of the aircraft (Flight Cycles, Flight Hours intervals)
Date of Transfer of Title (ToT) of the aircraft to the customer (Calendar intervals) when (ToT-FF)<=3 Months
Date of manufacture of the equipment when ageing of the equipment is not linked to the airframe
Interval rules: Thresholds or intervals with multiple units: First to expire must be considered (when otherwise not stated) Page 123

operator) a set of maintenance tasks with closer intervals Æ Less engineering work
' Theoretical task interval not reflected
Usage parameter concept Usage Parameters Intervals only
Used for WB, SA and LA
& Flexibility as no more pre-planning/prepackaging at airline level
„A“ check „C“ check
FH FC Cal. Time
Intervals are established in terms of the measure of exposure to the conditions that cause the failure at which the task is directed
Page 124
& Maximum interval & Direct Maintenance Costs savings due to Optimized Maintenance events based on real A/C utilization
' More planning work at airline level

Maintenance Program Customization MPD Customization – Work Scope
Why MPD customization is needed ? MPD is an envelope document and therefore contains scheduled maintenance tasks for the overall aircraft type. Design standards generally differs from one aircraft to the other, thus, an operator fleet is not concerned by all tasks.
What are the information needed to customize MPD ?
-
Aircraft type
- Weight variant
-
Engine type
- APU type
-
Mod Status
- SB status
-
Cabin Layout
- Emergency equipment list
How to select MPD tasks ? Select tasks according to Applicability column using the above listed documents

Some SSIs have different fatigue inspection requirements for the various Weight Variants (WV) of an aircraft type.
The Weight Variant represents the delivery standard of each aircraft.

A/C subject to a WV change through a service bulletin embodiment which implies a Group change: ¾
the maintenance requirements that apply are those with the lowest threshold and interval figures applicable to this A/C during service life regardless of the current WV of that subject aircraft.
