CS 23.2510Equipment, systems, and installations

(a)The equipment and systems identified in CS 23.2500, considered separately and in relation to other systems, must be designed and installed such that:

(1)each catastrophic failure condition is extremely improbable; and

(2)each hazardous failure condition is extremely remote; and

(3)each major failure condition is remote.

(b)The operation of equipment and systems not covered by CS 23.2500 does not cause a hazard to the aeroplane or its occupants throughout the operating and environmental limits for which the aeroplane is certified.

Remarks F3061/F3061M-24a Standard Specification for Systems and Equipment in Small Aircraft At variance with F3061-24a, paragraph 4.4.2, use of system level verification is usually not acceptable, and it should be discussed with EASA. F3230-25 Standard Practice for Safety Assessment of Systems and Equipment in Small Aircraft For aircraft that are powered by electric motors, EASA has not yet accepted Table 3 of F3230-25, and its use should be discussed with EASA. F3227/F3227M-25 Standard Specification for Environmental Systems in Aircraft At variance with F3227-25, Oxygen Fire Hazards Analysis is not completely covered in current ASTM standards. At variance, additional means of compliance have been developed by EASA for the specific application [AMC & GM to CS-23: Issue 4] [AMC & GM to CS-23: Issue 5]
