Multi-Media NDT Procedures and Online-
Maintenance Assistance in the Frame of the
European R&D Project INDeT
(Integration of NDT)

Abstract Advanced information technologies are undergoing vast changes. Only a
few years ago, hyper- and multimedia were still in their infancy. A European research
group with considerable participation of Airbus studied the possibilities of
developing in-service applications from these technologies.
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.
An electronic demonstrator of a Multi-Media-Maintenance Manual (4M) has been
designed, developed and tested for its suitability for daily business within the
framework of the research project “Integration of Non-Destructive Testing“, (INDeT).
It is designed to substantially improve the efficiency of future maintenance
processes by using multimedia and remote diagnostics systems.
Further, in case of possible problems during a maintenance operation, the maintenance
engineer can log into the computers of specialists at the aircraft manufacturers’
via a telephone line. A small camera transmits live pictures of the aircraft – all
around the world if required. The specialist can now view the problem area and rapidly
support the engineer. Complicated descriptions on the phone and handwritten
notes transmitted per fax belong to the past. This process is called Online-
Maintenance Assistance (OMA).
The deployment of the modern information technology will result in saving significant
amounts of time and thus also reduce costs for the manufacturer (development
of new procedures/instructions) and the airlines (application of these procedures/
instructions).
Creating and ensuring uniformity of structures and work processes in manuals and
procedures will additionally result in a considerable reduction of the “human factor“
as a potential influence on the measured results. By using multimedia-based forms
of procedures and manuals, these procedures will be “less misinterpreted“, as animations
and links within documents can point out changes and new items more effectively.
1. Introduction
The Non-Destructive-Testing (NDT) community in the aerospace business has done a lot of
research on new technologies to enable new and effective ways to inspect aircraft structures.
Less research has been done on the “infrastructure” for NDT. These infrastructures
are:
ECNDT 2006 - Th.4.1.1
1
• Non-Destructive Testing Manual (NTM)
• NDT procedures
• Adjustment and handling of complex NDT equipment
• Support for NDT staff at Airlines and Maintenance and Repair Organizations
(MRO)
• Collection and analysis of structural life cycle data
These topics and some others were worked out in the INDeT project.
The overall objective of the INDeT project was to
”Give the aeronautical industry the benefit of the introduction of powerful modern and economic
tools offered by the Information and Communication Technologies (ICT) for the
development and the improvement of non destructive inspection methods and concepts in
production and maintenance, resulting in saving costs - both for the manufacturers and airlines
-, increasing efficiency and reliability of the diagnosis and guaranteeing high levels of
safety”.
2. What is INDeT?
INDeT was an European research project in the Fifth Framework Program (FP5) of the
European Commission (EC). It started in 2002 and was finished in 2005. 13 partners from
all over Europe were participating:
• Aerospace OEM
o Airbus in Spain and Germany
o EADS-Corporate Research Center, France
o Alenia
o Dassault
• Universities and Institutes
o University of Applied Sciences Furtwangen, Germany
o University of Central Lancashire (UCLAN)
o University of Limerick, Ireland
o CNR-ISTI, Italy
• Small and Medium Enterprises (SME)
o Tanner, Germany
o NDTexpert, France
o Tecnatom, Spain
o IntelTec
o Sogitec
The main topics which have been investigated in INDeT were:
• 4M (Multi-Media Maintenance Manual)
• 3MP (Multi-Media Maintenance Portal)
