Mechanical Failure

Failure analysis has roots that run deep in mechanical engineering. When something fails there are a number of questions – and failure analysis provides the answers. Garrett’s Mechanical Engineers are qualified to conduct investigations of machinery defects and failures. These experts investigate, test, and offer insights about the machinery, code compliance, as well as safety and reliability issues relating to a mechanical failure. Their in-depth examinations are designed to help understand how the failure occurred, whether it was a defective part, or operator negligence that contributed to the breakdown. With wide-ranging expertise, Garrett’s Mechanical Engineers can assess such items as:


Garrett’s experts can determine why an appliance failed by investigating if it had an improper design and/or was used and/or maintained improperly. They can also identify what part or component of the product caused the failure and why.

Automotive Component/Mechanical Failures

Garrett’s Automotive Engineers evaluate claims of auto component failure related to such items as: brakes & braking systems; suspensions; tires; engine; transmission and other system components considered to be the possible cause(s) of an accident. By examining a vehicle and its component parts, our experts can determine if the cause of failure were already known (i.e. recalls), due to long-term wear-and-tear and/or a single event.


Garrett’s Engineering Experts are often asked to review documents and perform site inspections to determine what may have led to an injury on an elevator or escalator. As part of their review, it can be determined if proper service and maintenance had been performed prior to the accident and/or, if the costs involved in the repair of the elevator or escalator were in-line with industry standards.

Medical Equipment

Garrett’s experts can identify, investigate, and analyze safety issues and failures relating to machinery involved in an accident by examining equipment design, operation manual and instructions, safety features, and other information pertaining to safe and appropriate operation of the machinery. They can also determine the cause of the failure and whether that failure was due to such items as: improper design and/or use; component(s) stress/fatigue; inadequate maintenance and/or training.

Metallurgy Testing

Garrett’s Metalllurgy Experts examine evidence of metal/plastic failures, down to microscopic levels, to determine the cause(s) of a failure. Their investigations include examining the metal/plastic itself as well as its properties, the failed item’s processing and use to reveal if long-term cracking/damage or a single-event failure was a primary contributor to the failure.

Safety and Code Compliance

Garrett’s Safety and Code Compliance Experts assist on code compliance and safety issues at construction sites and workplaces to determine what procedures should have been followed to prevent accidents. They also look for potential hazards by inspecting facilities, machinery, and safety equipment to make sure that they meet safety requirements.
