Occurrences reporting
=============================

An occurrence is an aircraft malfunction that may endanger the safety of the aircraft. In order to raise an occurrence, the user can go to ``FRACAS > Continued Airworthiness``. After filtering a period of time, all the defects are presented. Then, the user has to create an occurrence if necessary.

There are two ways to associate a criterion to a defect:

- Searching by ATA chapter
- Searching by keywords

In any case, the user has then to select an associated criteria in order to create the occurrence.
