15.1 An FMEA test programme shall be drawn up
to prove the conclusions of FMEA. It is recommended that the test
programme shall include all systems or system elements whose failure
would lead to:
-
.1 major or more severe effects;
-
.2 restricted operations; and
-
.3 any other corrective action.
For equipment where failure cannot be easily simulated on the
craft, the results of other tests can be used to determine the effects
and influences on the systems and craft.
15.2 The trials shall also include investigations
into:
-
.1 the layout of control stations with particular
regard to the relative positioning of switches and other control devices
to ensure a low potential for inadvertent and incorrect crew action,
particularly during emergencies, and the provision of interlocks to
prevent inadvertent operation for important system operation;
-
.2 the existence and quality of the craft's operational
documentation with particular regard to the pre-voyage checklists.
It is essential that these checks account for any unrevealed failure
modes identified in the failure analysis; and
-
.3 the effects of the main failure modes as prescribed
in the theoretical analysis.
15.3 The FMEA tests on board shall be conducted
in conjunction with the provisions specified in 5.3, 16.4 and 17.4 of this Code, before the craft enters
into service.
