of each aircraft and can store this under an ATA

identify the different suppliers of the part.
Maximo also has links to the IPC so that
the correct parts can be identified.”
M&E IT systems communicate with
the OEMs’ and suppliers’ systems via
Spec 2000. “The airline’s system logs into
the suppliers. VISaer checks the various
capabilities of suppliers, including repair
capabilities, level of availability,
availability lead times, and purchase
discounts available and warranties that
are offered,” says Bruch. “VISaer also
allows the purchaser to ask for
alternative parts if the required one is not
available, as well as enquiring about
superseded and obsolete part numbers.
Prices of various suppliers can also be
checked.”
Technical manuals
There are many types of technical
manuals used in maintenance and
engineering, including: the IPC for listing
and illustrating parts; aircraft
maintenance manual (AMM) in assisting
with maintenance tasks; fault isolation
manual (FIM) for isolating faults during
line maintenance; troubleshooting
manual; and wiring diagram manual.
These have traditionally been supplied by
OEMs in paper format or in some cases
on microfiches. Engineering departments
constantly receive revisions and updates
to these manuals and this process requires
a large infrastructure. Manuals are then
consulted during operations, line
maintenance, hangar checks and in
component repairs.
These manuals can now be accessed
in electronic format and used in the
various M&E IT systems. “As an
example, pages of these manuals can be
accessed by mechanics via tablet
computers while performing work, with a
hyperlink to access the manuals,” says
Hughes. “This saves mechanics the time
they would spend searching through
manuals. Task cards can also be called up
on tablet computers, together with
pictures of the AMM or other
manuals. Our AuRA system goes out on
the server to the OEM’s data and gets the
latest manual. This leaves it up to the
OEM to provide the latest picture of a
manual’s page, and means the engineering
department no longer has to maintain
and keep its manuals up to date. We are
working closely with technologies like
Jouve, and with OEMs like Airbus and
Embraer on this integration.”
Manuals can be accessed from OEMs
in several ways. “They can be accessed
via the server or uploaded into the
airline’s M&E IT system,” explains
Dibble. “Revisions to manuals are made
automatically by updating the link to the
OEM.”
Bruch explains that manuals can also
be accessed via the internet. Airlines have
to pay for this on-line service, but realise
savings because they no longer have to
pay engineers to update and manage
manuals.
Jouve provides another method of
accessing technical manuals. Jouve’s
AirGTI manual takes OEMs’ manuals
and improves them. The manuals that
can be viewed on AirGTI include: the
aircraft maintenance manual (AMM),
aircraft illustrated parts catalogue (AIPC),
fault rectification and fault isolation
manual (FRMFIM), electronic illustrated
parts catalogue (EIPC), Aircraft service
manual (ASM) and aircraft wiring
manual (AWM).
“One example is by generating several
thousand hyperlinks between wiring
diagrams and wiring lists,” explains
Geoffrey Godet, president of Jouve. “A
mechanic looking at the AMM will
search for a part of sub-assembly in the
AMM and can open it at the page level. It
can also get groups of repair manual
pages and acquire the graphics associated
with the AMM text. AirGTI also has a
‘limit by’ function, which lists the aircraft
to which the particular page of the AMM
relates, ensuring the correct manual is
used.
“The IPC can be searched by ATA
chapter, by proximity to an aircraft part
or structure, or by a word search. Once
the part is found AirGTI gets a picture of
the part, but the mechanic also needs to
know the part number,” continues Godet.
“The IPC shows an item number, and this
item number is used to find the part
number. The ATA chapter system uses a
hierarchy to locate the part number.”
