(a)
Each item of equipment, each system, and each installation :
(1)
Whenperformingits intended function, may not adversely a.ect the response, operation, or accuracy of any–
(i)
Equipment essential to safe operation; or
(ii)
Otherequipment unlessthereisa meanstoinformthepilot of the e.ect.
(2)
In a single-engine airplane, must be designed to minimize hazards to the air-plane in the event of a probable malfunction or failure.
(3)
In a multiengine airplane, must be designed topreventhazards to the airplane in the event of a probable malfunction or failure.
(4)
[In a commuter categoryairplane, must be designed to safeguard against ha-zards to the airplane in the event of their malfunction or failure.]
(b)
The design of each item of equipment, each system, and each installation must be examined separately andin relationship to other airplane systems andinstallations to determine if the airplane is dependent upon its function for continued safe .ight and landing and, for airplanes not limited to VFR conditions, if failure of a system would signi.cantly reduce the capability of the airplane or the ability of the crew to cope with adverse operating conditions. Each item of equipment, each system, and eachinstallationidenti.ed by this examination as one upon which the airplane is dependent for proper functioning to ensure continued safe .ight and landing, or whosefailure would signi.cantly reduce the capability of the airplane or the ability of the crew to cope with adverse operating conditions, must be designed to comply with the following additional requirements :
