ACCIDENT RECONSTRUCTION - FAILURE ANALYSIS - FORENSIC INVESTIGATION

Accident Reconstruction is the analysis of the facts and physical evidence obtained from an accident investigation. It involves the application of scientific principles for the purpose of determining how an accident occurred. Santeler Forensic Engineering, PLLC employs the best generally accepted methodologies to analyze the facts and physical evidence from a collision. Investigation reports, vehicle inspections, imaging of Event Data Recorders (EDR) and Electronic Control Modules (ECM), tests, scene measurements, photographs, and witness testimony are used to determine vehicle speeds, positions, directions, and avoidance maneuvers. The interaction of the road, the driver, and the vehicle is considered in the evaluation of accident causation. Scene diagrams, simulations, and animations are created to enhance ones understanding of an accident.

Questions regarding the involvement of the product or vehicle as a cause for an accident or injury often arise. Design defects, manufacturing defects, improper maintenance, or improper warnings are frequently theorized to have been causative to an injury.

Through the analysis of a failed component and evaluation of its design, manufacture and use, Santeler Forensic Engineering, PLLC can determine the extent that a product may or may not have contributed to an injury. Additionally, they often investigate the history of the product, review regulatory compliance, study maintenance procedures, operator training, and other pertinent information to help determine cause and effect and create create failure analysis models. Findings are then translated into understandable exhibits that may consist of reports, diagrams, charts, models, or animations. In some cases, accident reconstruction and product analyses are combined to produce a better understanding of an accident.

The EXPERTS

Prior to working as a consulting engineer Mr. Santeler was a Chief Engineer with an industrial corporation overseeing design, testing, and research & development projects. Mr. Santeler has performed failure analysis and led teams of engineers to investigate production and field failures of commercial and military aerospace components. In these investigations he has utilized his experience in finite element analysis (FEA) methods and statistical approaches to investigate component and system failures. In addition to failure analysis, Mr. Santeler has extensive experience in product and process design, 3D computer modeling, drawing review, and developing design concepts from creation to production.


Mr. Santeler is also experienced in investment casting component and tool design, as well as failure analysis of cast components relating to the casting process and operational failures. He is a certified Design for Six Sigma (DFSS) Black Belt and is the inventor or co-inventor on sixteen (16) patents and one (1) patent application.  He is a member of several industry professional organizations.


Mr. Santeler is certified in both Accident Reconstruction and Vehicle Dynamics by the Society of Automotive Engineers including training in: Accident Reconstruction Methodology, Vehicle Dynamics, Commercial Vehicle Brake Systems, Automotive Brake Control Systems, Photogrammetry, and Video Analysis. He has completed training courses from the Northwestern University Center for Public Safety (NUCPS) and the Collision Safety Institute (CSI) in automotive Event Data Recorder imaging (downloading) and data analysis. Mr. Santeler has also completed SAE training courses for both Automotive and Heavy Vehicle Event Data Recorder (EDR, black box) imaging, analysis, and application to Accident Reconstruction. His curriculum vitae is available on request.
David Sallmann has worked in the field of automotive and forensic engineering for over 50 years. For more than 30 years David Sallmann served Rudny & Sallmann Engineering and then mentored Keith Santeler, PE prior to Mr. Santeler taking over the business. During that time he has consulted and provided expert testimony regarding accident reconstruction and vehicle designs. He has performed numerous tests on vehicles and vehicle components and performed staged collisions on automobiles, light trucks, and motorcycles.


Prior to founding Rudny & Sallmann Engineering, he designed, tested and developed construction, mining, and agricultural vehicles for several major manufacturers. In addition to a list of vehicle designs, David Sallmann developed heavy-duty brakes, transmissions, and axles. He also developed standard test procedures and wrote service manuals for off-highway vehicles.


David Sallmann has served as a member of several SAE committees including the Accident Investigation / Reconstruction Practices Committee, the Accident Reconstruction Publications Review Committee and the Heavy Truck Reconstruction Forum. He has also served as a member of the SAE Drivelines and Transmissions Organizing Committee and the Trailer Sway Stability Subcommittee. David Sallmann has also published peer reviewed articles regarding accident reconstruction.


In addition to his experience with land vehicles, David Sallmann has extensive experience with watercraft. He has taught classes in boating safety and has testified regarding watercraft accidents. His curriculum vitae is available on request.

FAQ

What is accident reconstruction?


The analysis of the facts obtained from an accident investigation and the application of scientific principles for the purpose of determining how the accident occurred.

How much does a reconstruction cost?


The cost is dependent on the time involved to gather facts, analyze, and present opinions.  The extent of reporting will also weigh into the ultimate cost.

Are vehicle damage measurements always needed to reconstruct vehicle speed?


No. Certain types of collisions involving some vehicles may require knowledge of crush damage to reconstruct speed. Frequently, scene data is can be just as useful to determine vehicle speed.

Are accident scene measurements of vehicle impact and rest positions always required to reconstruct an accident?


No. Scene measurements can be beneficial, but scene photographs and even witness testimony may provide the needed information.

Do all recently produced automobiles and trucks have data recorders that provide accident data?


Most automobiles and light trucks produced in recent years have event data recorders as part of the air bag system. However, recorded data varies by manufacturer. Many heavy trucks are equipped with individual electronic control modules (ECM) for the engine, transmission, and brake system. These ECMs can be capable of recording crash data or other parameters useful in accident reconstruction. Also, the electronic logging device (ELD) in commercial trucks may have useful data as well. Please contact us to find out what data the vehicles involved in your accident may record.

Will the data recorders provide vehicle speed at impact and also speed prior to impact?


The data available varies by manufacturer. Many automobiles and light trucks record this data as well as some heavy trucks. Please contact us to find out what data the vehicles involved in your accident may record.
