1. A method for analyzing faults present on a platform, in particular an aircraft, including the following steps:
- (a) providing a table of correspondence between a plurality of observable symptoms on the platform and fault modes capable of creating each observable symptom;
(b) measuring the symptoms present on the platform and selecting at least part of the measured present symptoms;
(c) establishing at least one family of faults, the establishing comprising;
obtaining, from the table of correspondence, a list of fault modes capable of creating, alone or in combination, all of the selected symptoms that are present; and
, for each fault mode of said list;
placing the fault mode in a fault family;
grouping together, within the same fault family as the fault mode, all of the fault modes of said list capable of creating at least one selected present symptom in common with the fault mode.

Abstract
A method for analyzing faults present on a platform includes the following steps:
- (a) providing a table of correspondence between a plurality of observable symptoms on the platform (10) and the fault modes capable of creating each observable symptom;
- (b) measuring the observable symptoms present on the platform (10);
- (c) establishing at least one family of faults, including determining a list of fault modes capable of creating, alone or in combination, all of the selected present symptoms, placing each given fault mode of the group in a fault family, and grouping all of the fault modes capable of creating at least one selected present symptom shared with the given fault mode together in the same fault family as the given fault mode. The method is applicable to fault analyses on aircrafts.

19. A system for analyzing faults present on a platform, comprising:
-
a processor for storing a table of correspondence between a plurality of observable symptoms on the platform and fault modes capable of creating each observable symptoms; detectors for measuring the observable symptoms present on the platform and selecting at least some of the measured present symptoms; a processor for establishing at least one fault family, the processor being configured to; obtain, from the table of correspondence, a list of fault modes capable of creating, alone or in combination, all of the selected present symptoms; place each fault mode of said list in a fault family; group together, in the same fault family as the fault, all of the fault modes from the list capable of creating at least one selected present symptom shared with the fault mode.
