3. Why INDeT?
Information and communication technologies like Internet, mobile phones, and more generally
computer-based systems belong now to our daily life. These fabulous modern tools
contribute widely to decrease paper media, speed up the circulation of information and
strengthen reactivity when you have to face up to difficulties. Today, inspection electronics
are already frequently coupled with PC technology, which will surely still increase in the
near future. This means that the majority of the modern inspection equipment already has
the hardware platform for the documentation system.
Besides, the aeronautical industry still uses a lot of paper media especially for maintenance
inspections for airlines. Current procedures and manuals written exclusively in English can
sometimes be difficult to understand and interpret. The result can be that this bulky mass of
papers and documents to store persuades the inspector not to use the last updated procedure
version or to glance quickly through the modifications mentioned without remembering
them. Airlines often rebuild manufacturers’ raw data and re-split the contents of manuals/
procedures in order to get the exact information needed to answer end-user expectations.
The difficulties with the application are thus not the result of poor technical implementation.
Rather, the medium (paper) is the decisive parameter that prevents an improvement of
applicability.
4. The 3MP
One of the main questions during the project was, how to handle and organize the tools
which have been developed. The solution was a platform, from which all application can be
selected and started. This platform was named: Multi-Media Maintenance Portal (3MP)
(refer to figure 1).

4.1. 4M
The documentation for maintenance is handled in several different manuals, e.g.:
AMM – Aircraft Maintenance Manual
MPD – Maintenance Planning Document
MRB – Maintenance Review Board
SRM – Structural Repair Manual
NTM – Non-Destructive Testing Manual
Within the INDeT project the NTM was analyzed and transferred into the multi-media
demonstrator.
So some years ago, the NTM was a fully paper-based document. Hundreds of pages of paper,
mainly text, illustrated by some graphics in black and white, properly sorted into DIN
A4 folders with an overall thickness of 12 cm and a weight of approx. five kilograms – this
is the documentation (NTM – Non-Destructive Testing Manual) according to which the
most advanced civil aircraft are carefully and reliably tested for damage such as cracks,
corrosion or deformations. This paper document was than “digitized”. That means, that the
paper documents were transferred one by one onto a CD. So the weight was reduced, but
the type of documentation was still the same.
The change to multimedia documentation will bring a range of innovations for the operator.
Addressing the human factor is an important point in aeronautics as it influences directly
inspection reliability. First it will be possible to develop multi-media procedures where the
structure, its characteristics and the inspection conditions can be more clearly illustrated,
using relevant pictures, drawings, photos, CAD part descriptions or movies. This will be a
definitive benefit in understanding for operators whose mother tongue is seldom English.
For complex procedures, more specific information will also be inserted in order to avoid
potential interpretation error. A digital documentation will be adaptive, interactive and
more accessible thus easier to consult, and operators will be more disposed to read it. Indeed,
in the case of multi-media information, it is quicker to find the required item, using
key-words and embedded links. IT tools enable as well to highlight the most important
points such as a revision in procedure. The inspector will also have the opportunity to familiarize
with new NDT methodologies and emerging technologies in a user-friendly way.
The information being easier to access and to interpret, time would be saved in the preparation,
realization and interpretation of inspection operations thus saving cost.
The multi-media elements, which are used in the 4M are:
• Photos
• Films
• Animation
• Colored Graphics
• Sound
