FAR 29.1163 : Powerplant accessories.
(a)
Each engine mounted accessory must–
(1)
Be approved for mounting on the engine involved;
(2)
Use the provisions on the engine for mounting; and
(3)
Be sealed in such a way as to prevent contamination of the engine oil system and the accessory system.
(b)
Electrical equipment subject to arcing or sparking must be installed to mini-mize the probability of igniting .ammable .uids or vapors.
(c)
If, continued rotation of an engine-driven cabin supercharger or any remote accessory driven by the engine will be a hazard if they malfunction, there must be means to prevent their hazardous rotation without interfering with the continued operation of the engine.
(d)
[Unlessother meansareprovided,torquelimitingmeans mustbeprovidedfor accessorydriveslocated on any component of the transmission and rotordrive system topreventdamage to these componentsfrom excessive accessoryload.]

FAR 29.1165 : Engine ignition systems.
(a)
Each battery ignition system must be supplemented with a generator that is automatically available as an alternate source of electrical energy to allow continued engine operation if any battery becomes depleted.
(b)
The capacity of batteries and generators must be large enough to meet the simultaneousdemands of the engineignition system and thegreatestdemands of any electrical system components that draw from the same source.
(c)
The design of the engine ignition system must account for–
(1)
The condition of aninoperativegenerator;
(2)
The condition ofa completelydepletedbattery withthegenerator running atits normal operating speed; and

(3) The condition of a completely depleted battery with the generator ope-rating at idling speed, if there is only one battery.
(d)
Magnetoground wiring(for separateignition circuits) thatlies onthe engine side of any .rewall must be installed, located, or protected, to minimize the probability of the simultaneous failure of two or more wires as a result of mechanical damage, electrical fault, or other cause.
(e)
No ground wire for any engine may be routed through a .re zone of another engine unless each part of that wire within that zone is .reproof.
(f)
[Each ignition system must be independent ofany electrical circuit that is not used for assisting, controlling, or analyzing the operation of that system.]
(g)
There must be means to warn appropriate crewmembers if the malfunctioning of anypart of the electrical systemis causing the continuousdischargeof any battery necessary for engine ignition.
