Bosch Releases CDR Version 14.0

On August 29th, 2014 Bosch CDR (Crash Data Retrieval) announced the release of its latest software version, 14.0.  The new software adds airbag module imaging support for select 2015 Audi vehicles sold in the US and Canada.  Select Audi vehicle “black boxes” can now be accessed via the DLC (Diagnostic Link Connector) or by directly connecting to the vehicle’s Airbag Control Module (ACM).  The select Audi vehicles which are now supported include:
  • Audi A3
  • Audi A4
  • Audi A5
  • Audi A6
  • Audi A7
  • Audi A8
  • Audi Q3
  • Audi Q5
In addition, Bosch has also released a software patch (Version 14.0.1) which adds coverage for the 2014 and 2015 Volkswagen EOS models. The Bosch CDR system supports select airbag modules for vehicle as far back as 1994.  To see if the pre-crash data from your vehicle’s airbag module can be downloaded please see the BOSCH CDR Coverage List. Veritech engineers utilize the Bosch CDR system as an important tool to aid in performing vehicle accident reconstructions.  Airbag modules are capable of recording valuable pre-crash information, such as vehicle speed, brake application and seatbelt usage, but are not capable of telling the entire story.  Accident reconstruction engineers must still consider all of the available physical evidence, along with the ACM data, in to order to properly reconstruct an accident.  Veritech Consulting Engineering employs Professional Engineers who are specifically trained and certified in the use of the Bosch CDR system and have performed numerous accident reconstructions utilizing airbag module information.  Please visit our web page at for additional information on “black box” technology.

The “Black Box” Revealed: History of Flight Data Recorders

How many time have we heard that investigators are searching for the “black box” after an aviation accident? This refers to the flight data recorder (FDR) which all commercial and corporate airplanes in the United States are required to carry. They are also required to be equipped with a cockpit voice recorder. It might seem like the FDR is an extremely modern, space age device, but in fact, the earliest type of flight recorders date back to 1939. Developed in France by François Hussenot and Paul Beaudouin, their “type HB” flight recorder used a photographic record. Another early version was developed in the UK during World War II by Len Harrison and Vic Husband. Their technology used various styli which indicated readings of various instruments / aircraft controls and were recorded on copper foil. Modern FDR technology was invented by Dr. David Warren at the Aeronautical Research Laboratory in Melbourne, Australia. In the mid-1950s he took part in the investigation of a mysterious crash involving the world’s first jet-powered commercial aircraft, the Comet. It occurred to Dr. Warren that if there had been some kind of recording of what was happening on the aircraft just prior to the crash—that would have been a huge help to the investigation. His first demonstration unit was produced in 1957. In 1960, an unexplained plane crash in the northern part of Australia prompted that government to make the Black Box mandatory for all commercial aircraft. They were the first country to do so. The media was quick to adopt the term, “black box.” Although the origins of the term “black box” are uncertain, what is certain is that having them onboard aircraft has revolutionized the accident reconstruction industry. Black Box Facts: • FDRs are not located in the cockpit of an aircraft, but rather in the rear, typically in the tail. Why? It’s unlikely that a plane would go down tail first. The entire front and midsection of the plane acts as a buffer, to reduce the shock reaching the recorder. • Today’s black box is not black at all, but a bright orange for ease in spotting it among the wreckage in case of an accident. • Black boxes emit an underwater locator beacon for up to 30 days, in case of a water crash. They can operate in depths of up to 20,000 feet.

As the Motorcycling Community Grows, so do Fatality Rates

The National Highway Traffic Safety Administration’s (NHTSA) website reports on recent trends in their Motorcycle Safety Program. They state that the numbers of motorcyclists on our nation’s roads continues to expand at a rapid pace. New unit sales of on-highway motorcycles have increased approximately 91 percent since 1997. The Motorcycle Industry Council (MIC) predicts continued increases in motorcycle sales over the next 5 to 7 years as well. Although the NHTSA doesn’t go into much detail about the reasons behind these increases, they do share some sobering statistics. Although helmet use is falling, leading to more fatalities, helmet usage is not now and has never been the cause of accidents. Rider impairment, lack of skill/training, and excessive speed are contributing factors in many motorcycle crashes. For fifty percent of motorcycle fatalities in single vehicle crashes (no other vehicle involved) difficulty negotiating a curve has been found to be a major contributing factor. Almost 60 percent of motorcycle fatalities, also single vehicle, happen at night. More than 80 percent of single vehicle crash fatalities occur off the roadway itself. This could be on the median, shoulder, in parking lanes, and gores (area where to roads either converge or diverge.) NHTSA also reports that motorcyclists over 40, specifically those riding larger motorcycle engine sizes, now are the fastest growing group of motorcyclist fatalities. No specific reasons for this are given. In contrast, over the past 10 years, fatalities in the 20 to 29 year old age group decreased. This was the group that had consistently had the highest fatality rate in the past. Again, no reasons are given. During this time, however, there were more driving age individuals in the 40 and over age group in the United States. According to NHTSA statistics, only 20 percent of passenger vehicle crashes result in injury or death. But a whopping 80 percent of motorcycle crashes result in injury or death. In 1997, NHTSA partnered with the Motorcycle Safety Foundation (MSF). Together, they created the National Agenda for Motorcycle Safety (National Agenda). This strategic planning document was intended to provide a shared National vision for future motorcycle safety efforts.

NTSB Releases Preliminary Report on Collapse of I-5 Bridge in Washington State

The National Transportation Safety Board continues their investigation into the I-5 bridge collapse over the Skagit River in Mount Vernon, WA. Although the collapse occurred on May 24, 2013, to date they have only released a preliminary report, covering the circumstances and causes of this collapse. The details from PRELIMINARY REPORT HIGHWAY HWY13MH012 are as follows: On Thursday, May 23, 2013, a span of the Interstate 5 Bridge (Structure 4794A) at milepost 228.25 in Mount Vernon, Skagit County, Washington, collapsed into the Skagit River.The bridge was constructed in 1955 and the collapsed span consisted of two northbound and two southbound traffic lanes divided by a concrete barrier. Leading up to the collapse, a Kenworth truck-tractor hauling an oversize load was following a pilot vehicle southbound on I-5. Witnesses reported that as these two vehicles approached the bridge, a second southbound tractor-trailor overtook and passed the vehicle with the oversize load in the left lane. The driver of the first tractor-trailor reported to NTSB investigators that he had felt “crowded” by the other vehicle trying to pass. In reaction, he moved his vehicle over towards the right hand side of the road. As the oversize load he was hauling moved onto the bridge, it collided with the overhead portal and multiple sway braces on the far right side of the truss structure. This caused major damage to load-bearing members of the bridge’s superstructure. The result was the subsequent collapse of the bridge into the river. The height of the oversize load was a major contributing factor. The driver reported the height of the load to be 15 feet 9 inches, but the lowest portion of the sway braces was later measured at only 14 feet 8 inches. Two passenger vehicles were also on the bridge span at the time of the collapse, and wound up in the river as well. Injuries but no fatalities were reported. The second part of the NTSB’s report has yet to be issued and the investigation is still listed as ongoing and active.

NTSB Investigates Fatal Metro-North Derailment

The National Transportation Safety Board (NTSB) report on the Metro-North derailment in the Bronx is only in its first days, but it has already turned up some startling facts. The train derailed on the morning of Dec. 1, right outside the Spuyten Duyvil station, with four fatalities and 70 injuries as the tragic result. As is customary in NTSB investigations, as well as all kinds of accident reconstructions, two event recorders from the derailed train were examined. The train, plane, or truck’s speed is just one of the many specifics documented by the vehicle’s event recorder. According to NTSB board member Earl Weener, the train headed into the curve just ahead of the station at 82 mph, in a zone where the speed limit drops from 70 mph to 30 mph. In addition, the NTSB also found some kind of problem with the train’s brake pressure. A mere five seconds prior to the engine finally stopping, brake pressure dropped from 120 psi to 0. NTSB investigators still have more work to do to determine whether or not the brakes were functioning correctly and why the pressure went to 0. U.S. Sen. Richard Blumenthal (D-Conn.) remarked that “given this was the fifth major accident or malfunction on the Metro-North Railroad in just over six months, major questions have arisen about safety on the commuter railroad system.” As of Dec. 3, the NTSB states that it remains unclear whether human error or faulty equipment was responsible for this deadly derailment. Their investigation continues. Needless to say, this fatal accident has brought service on the line to a halt, inconveniencing thousands of commuters. N.Y. Governor Cuomo said in a statement on Monday that he expects to see Metro-North service restored toward the end of the week, though officials for the railroad itself said there was no definitive timetable for full service.

How the NTSB Investigates an Accident

The National Transportation Safety Board (NTSB) is the independent Federal Agency tasked with investigating every civil aviation accident in the U.S. and significant accidents in other modes of transportation. This can include railroad, highway, marine and pipeline. When an accident occurs, their investigators are immediately sent to the scene. Called the “Go Team,” these experts are on call and must be ready to leave quickly during their duty shift. The team can number anywhere from three to more than a dozen specialists, depending on the nature of the accident itself. Their purpose: to begin the investigation into the causes of the accident right at the scene. Team members are sent from the NTSB’s headquarters in D.C., and they may travel to the accident scene either on a commercial airliner or on a government plane. They work under an Investigator-in-Charge. This is a senior investigator, who has many years of experience. Each investigator on the “Go Team” is an expert in a particular area and is responsible for one, clearly defined area of the investigation. Each of these experts head a “working group,” which is basically a subcommittee consisting of the representatives of many other involved parties. For example, for an aviation accident, a working group might consist of the NTSB specialist and representatives from the Federal Aviation Administration, the airline, the pilots’ and flight attendants’ unions, airframe and engine manufacturers, and the like. Aviation accidents are particularly complex, requiring bigger teams with more specialists. For surface accidents, such as the recent Dec. 1 Metro North derailment, a locomotive engineers, signal system specialists and track engineers would head the working groups, along with representatives from Metro North and any unions involved. During the on-scene investigation, only confirmed, factual information is ever released to the public. The NTSB does not ever speculate about cause. After the on-scene investigation, the second stage of the investigation continues at NTSB headquarters in Washington. One of the main roles of the Board is to issue recommendations for improving transportation safety. It might take the board a year or more from the date of the accident for the board to conclude their investigation, analyze all the data, and present a report including their recommendations.

NTSB Reports on Airplane Accidents Caused by Wildlife

Much is made in the news about terrorist attacks on airplanes, of course with good reason. But there are other, somewhat “hairier” things that can also take a plane down (no pun intended). Take a look at these two reports from the NTSB (National Transportation Safety Board):

In the first incident, the NTSB reports that a plane was attempting to land on a small airport runway, when a deer ran onto the pavement right toward the oncoming plane. The pilot attempted to climb, but couldn’t accomplish it before the deer struck and substantially damaged the left horizontal stabilizer. The pilot was able to stop without further incident, and no mention is made of what happened to the deer.

For an incident like this, the NTSB didn’t send an investigator, but depended upon reports from the FAA and the pilot to make its determination: The probable cause(s) of this accident—An inadvertent collision with a deer during landing. This raises the question of whether or not the airport should have had a fence, however, no fence could have prevented what happened in the next incident.

The second reported incident took place between a student pilot and our national bird, the bald eagle. According to the flight instructor, the plane was 1,000 feet above the ground when the eagle hit the right horizontal stabilizer. The instructor immediately took over and landed at the nearest airport. He reported that the rudder controls were impaired on final approach, but he managed to land without incident. Again, nothing was mentioned as to what happened to the bald eagle.

However, the plane showed a large indentation on the right horizontal stabilizer with bird feathers embedded in it. The tail cone was shoved upward into contact with the rudder, which had impeded the rudder’s movement.

For those of you unfamiliar with NTSB, it’s an independent branch of the government charged with advancing transportation safety. The NTSB’s mandate is to investigate every civil aviation accident, as well as major accidents in other types of transportation, including train accidents, marine accidents, and even pipeline accidents. They attempt to determine the probable causes and issue recommendations for safety improvements that could prevent future accidents.

California Police Departments Testing Cost-Effective Electric Motorcycles

USA Today reports that more police departments are trying out electric motorcycles. According to an article posted on Oct. 30, 2013, the San Mateo California police department has purchased one Zero electric motorcycle. San Mateo is joining several other California police departments in the San Francisco Bay Area in trying out the new, recently-developed motorcycle. It’s supposed to have various advantages over its gas fueled competitors, including, of course, a much lower cost to run. The bikes were specifically designed for law enforcement agencies, and are reported to be highly maneuverable in traffic. Their battery holds enough of a charge to last a police officer’s entire shift. According to Zero’s vice president, John Lloyd, “Police Departments are continuing to select Zero Motorcycles to be added to their fleets because the motorcycles have been developed from the ground up to meet the requirements of law enforcement agencies around the world.” For more information about Zero and their innovative line of products, click here. They have a compelling infographic titled, TOP 15 THINGS YOU’LL NEVER DO AGAIN. One of them is pump gas. Take a look here. Perhaps the most impressive advantage of these vehicles is that they cost about a penny per mile to run! In these days of ever-rising gas prices, that can’t be beat.  San Mateo’s Deputy Chief praised the Zero in a public statement, saying, “The Zero Police Motorcycle provides the solution that allows our officers to provide security without the intrusive odors and loud noises of traditional police motorcycles.” No one can argue with the idea of less intrusive odors on our nations roadways, but the loud noises the Deputy Chief referred to are one of the aspects of motorcycles that may keep a cyclist safer on the road. It’s been shown that car drivers frequently fail to see motorcyclists, because they are so much smaller, and this leads to accidents. Because of their quietness, electric motorcycles have created a fair amount of controversy. What impact will their introduction onto our roadways have in terms of automobile versus motorcycle accidents? We’ll talk more about this in our next post, so stay tuned.
