Abstract
The aim of this paper is to urge airlines' maintenance
organizations to look at their costs in a different way to the
normal, traditional ways of controlling spend against budget.
This is not to say that existing financial controls should be
done away with - far from it. The areas for review suggested in
this paper are additional and have yielded significant savings in
the past for airlines that have used these review techniques.
A lot of maintenance organizations find it difficult to state
what their costs are at any detailed level but even high level data
can be used to compare with other organizations to see if there is
a problem that needs to be addressed.
By looking at the content of the work pack for each heavy check,
it will usually be possible to take out many additional tasks that
have crept in but are no longer appropriate. The organization's
strategy on outsourcing its component maintenance or having its own
backshops can have significant implications on the level of cost.
By checking the average interval since the aircraft's last
heavy check, the organization can reduce the ""throwing
away' of remaining component life and can ensure that the
aircraft comes in for heavy maintenance no more frequently than
necessary. A number of suggestions are made for reviewing hangar
efficiencies.
Each airline will already be using some of these
recommendations, but most will be able to incorporate the
additional ones to their benefit
