Typical Questions:

Was it operator error?
Was the equipment designed and manufactured sufficiently?
Was the equipment maintained properly?
Were proper replacement parts used?
Was the equipment being used as intended?
Were proper warnings present?
Did a part fail?

When appropriate, exemplar equipment is tested to replicate the failure, or to eliminate causes. Mechanical failures can involve equipment ranging in complexity from relatively simple (lawn mowers) to extremely complicated (giant off-road excavator) equipment with a maze of sub-assemblies.

The failure of a small or inexpensive part(s) can result in major injuries and/or economic loss. Mechanical failures can contribute to vehicle crashes, including off-road equipment crashes.
