Damaged (patched, cut, bruised, cracked to braid or deflated) air bag
You must know the normal appearance of air bags used in vehicle suspension systems, be able to recognize the signs of damage and identify when the damage may also cause an air bag to be deflated. You must also know a vehicle has a major defect when any air bag is damaged and has no air in it.

Procedure:

    • Inspect the vehicle (or describe the process) to ensure an air leak is not noticeable in the air-suspension system and any air bag is not damaged and has air in it.

You must know the importance of doing a visual inspection of leaf springs and how to identify a broken leaf spring, and that the vehicle has this minor defect when any spring has a single broken leaf.

Cracked or broken main spring leaf or more than one broken leaf spring
You must know which leaves in a spring are considered to be “main” leaves, and that a vehicle has this major defect when either a main leaf or more than one other leaf is broken.

Part of leaf spring or suspension is missing, shifted out of place, in contact with another vehicle component
You must know the condition of the suspension-system components, and the hardware that attaches it to the vehicle need to be inspected visually; you must be able to recognize the signs of more serious unsafe suspension-system conditions, and that a vehicle has this major defect when any part of a leaf spring or suspension part is missing, has shifted out of place or is in contact with another vehicle component.

Procedure:

    • Inspect the vehicle (or describe the process where not accessible) to identify any cracked or broken spring leaves, or a spring leaf or suspension part is missing, has shifted out of place or is in contact with another vehicle component.
