S3000L is the international standard for Logistic Support Analysis.
Logistic Support Analysis is often abbreviated to LSA.
There are other standards for LSA, in individual countries.
One such example is the UK Defence Standard 00-600.
The advantage of the standard, is that it is international, rather than national.
The S3000L LSA procedure standard, is jointly published by two organisations.
The two organisations represent the aerospace industries of Europe and the USA.
The result of two publishers, are that you will come across two slightly differing titles.
In Europe the standard is published by the AeroSpace and Defence Industries Association of Europe.
The published S3000L standard in Europe is called ASD S3000L
In the USA the Aerospace Industries Association of America (AIA), publishes the standard.
The USA standard, whilst being exactly the same as the European ASD S3000L standard, is called AIA S3000L.
