Which amendment introduced CS 29.610?

Amdt 29/4 introduced CS 29.610.

CS 29.610 Lightning and static electricity protection

Q: How can compliance with lightning protection be demonstrated for non-metallic components?

For non-metallic components, compliance may be shown by (1) designing the components to minimise the effect of a strike, or (2) incorporating acceptable means of diverting the resulting electrical current to not endanger the rotorcraft.

Q: What are the four requirements for electrical bonding and protection against lightning and static electricity?

The electrical bonding and protection must: (1) minimise the accumulation of electrostatic charge; (2) minimise the risk of electrical shock to crew, passengers, and servicing and maintenance personnel using normal precautions; (3) provide an electrical return path, under both normal and fault conditions, on rotorcraft having grounded electrical systems; and (4) reduce to an acceptable level the effects of static electricity on the functioning of essential electrical and electronic equipment.

Q: Under what conditions must an electrical return path be provided on rotorcraft with grounded electrical systems?

An electrical return path must be provided under both normal and fault conditions on rotorcraft having grounded electrical systems.

Q: What specific risk to personnel must be minimised by the electrical bonding and protection requirements?

The risk of electrical shock to crew, passengers, and servicing and maintenance personnel using normal precautions must be minimised.

Q: What effect of static electricity must be reduced to an acceptable level?

The effects of static electricity on the functioning of essential electrical and electronic equipment must be reduced to an acceptable level.

Q: For metallic components, what are the two acceptable methods to show compliance with the lightning protection requirement?

For metallic components, compliance may be shown by (1) electrically bonding the components properly to the airframe, or (2) designing the components so that a strike will not endanger the rotorcraft.
