?NTSB_logoWASHINGTON – The National Transportation Safety Board (NTSB) unveiled its 2016 Most Wanted List of transportation safety improvements Wednesday, calling it a “road map from lessons learned to lives saved.” The list focuses on 10 broad safety improvements on which the NTSB has made recommendations that have not yet been implemented.

Several items on the list demonstrate the importance of technology in saving lives, preventing accidents and lessening the number and severity of injuries from accidents. For example, the list calls for promoting both the availability of collision avoidance technology in highway vehicles, and the completion of rail safety initiatives to prevent accidents. The list also calls for strengthening occupant protection in all modes of transportation, including laws mandating primary enforcement of seatbelt use, and age-appropriate child restraints.

Twenty years ago, the NTSB issued its first recommendation on the use of technology to prevent rear-end collisions. Implementation of this technology could significantly reduce motor vehicle crashes – by far the leading cause of death and injuries in transportation. Although federal regulators have made progress toward including such technologies in the 5-star safety rating on new vehicles, the NTSB advocates including such new technologies as standard equipment on all new highway vehicles – including commercial vehicles — just as airbags and seatbelts are now standard equipment.

The NTSB also called for completion of rail safety initiatives, including the implementation of positive train control (PTC). A 2008 law mandated implementation of positive train control by the end of 2015. Congress changed the law and implementation deadline late last year to avoid a possible rail transportation shut-down.

NTSB Chairman Christopher Hart cited the PTC implementation as an example of why a sense of urgency is needed in implementing Most Wanted List improvements. “Every PTC-preventable accident, death, and injury on tracks and trains affected by the law will be a direct result of the missed 2015 deadline and the delayed implementation of this life-saving technology,” Hart said.

The NTSB’s push to improve rail transit safety oversight was in part a result of the agency’s investigation of a deadly smoke event last January near Washington’s L’Enfant Plaza Metro station. The accident exposed many safety issues, some of which resulted from shortcomings in the safety oversight of WMATA. This year, the NTSB will continue to examine the way that the Federal Transit Administration is implementing such oversight – not only in Washington, but nationwide.

Improving rail tank car safety by phasing out the use of DOT-111 rail tank cars to transport flammable liquids such as crude oil and ethanol is another improvement addressed in the 2016 Most Wanted List. The deadline for implementing such tank rules is 2025. Until these tank cars are removed from service, people, their towns, and the environment surrounding the rail system remain at risk.

Distraction (especially from portable electronic devices) and fatigue continue to be serious safety issues in all modes of transportation, and the NTSB’s 2016 Most Wanted List addresses them all. The list also notes that undiagnosed and untreated medical conditions have caused or contributed to accidents and calls for operators and regulators to require medical fitness for duty.

Impairment is also an issue in all modes of transportation. The NTSB has recommended lowering the legal limit on blood alcohol content to .05 to reduce deaths and injuries on highways. However, drugs other than alcohol can also impair drivers and operators of other types of vehicles – whether these drugs are recreational, over-the-counter, or prescription.

Another improvement on the 2016 list is preventing inadvertent spins and stalls within the general aviation community – the worst safety problem facing general aviation. While airlines have become very safe, safety progress has slowed in the less widely understood world of general aviation.

All of these most wanted transportation safety improvements are the result of our accident investigations. Our most powerful tool to learn safety lessons from accidents is data recorders. Thus, the list calls for their increased use in all modes of transportation.

NTSB_logoWashington, D.C. – As part of its ongoing investigation of the derailment of a crude oil unit train in Casselton, North Dakota, the National Transportation Safety Board produced a Train Braking Simulation Study, which it placed into the investigation docket. The study was prompted by recent North American crude oil and ethanol train derailments that resulted in the release of large volumes of flammable liquids that endangered persons, property and the environment.

The study shows that Electronically Controlled Pneumatic (ECP) brake systems out-performed distributed power configurations, which in turn out-performed conventional brake systems. The study provides detailed description and analysis of each rail braking system and the stopping distances they achieved under various circumstances.

“Over the last decade, the NTSB has investigated a number of catastrophic flammable liquid unit train derailments. Our recommendations have called for improved technologies that can reduce or minimize the risk of derailments. Improved braking capabilities are but one part of the equation in making rail transportation safer,” said NTSB Chairman Christopher A. Hart.

The NTSB considered emergency and full service brake applications on uniform grade, tangent track with clean, dry rails. The study also evaluated the effect of different net braking ratios, which measure the amount of force applied by the brake shoes against the wheels. While ECP brake systems performed best, increasing the net braking ratio for any brake system substantially improved its stopping performance.

The NTSB’s investigation of the Casselton, ND accident is ongoing. Analysis of the accident, along with a determination of probable cause, will come later when the investigation is completed.

WASHINGTON – Christopher A. Hart was sworn as the 13th chairman of the National Transportation Safety Board March 17 during a ceremony presided over by Chief Administrative Law Judge Alfonso Montano.

President Barack Obama nominated Hart to serve as chairman in January 2015, and the U.S. Senate confirmed him on March 12, 2015. He has been serving as acting chairman since April 26, 2014.

Prior to stepping into the role of acting chairman, Hart had served as vice chairman and a member of the board since 2009. He also served as a member of the board from 1990 to 1993.

“I am very grateful for this opportunity to lead this dynamic agency that is dedicated to improving transportation safety,” said Hart. “I have been involved in transportation safety for more than 30 years, and the NTSB truly sets the bar higher for continued safety improvement.”

Hart is an aerospace engineer, attorney, and licensed pilot with commercial, multi-engine and instrument ratings. His family has a tradition of accomplishment in the field of transportation. In 1926, his great uncle, James Herman Banning, was the first African-American to receive a pilot’s license issued by the U.S. Government.

After serving as a member of the board from 1990-1993, Hart served as deputy administrator of the National Highway Traffic Safety Administration, before moving to the Federal Aviation Administration in 1995. He served as the FAA assistant administrator for System Safety and then became deputy director for Air Traffic Safety Oversight before returning to the board in 2009.

Hart holds a law degree from Harvard Law School and Master’s and Bachelor’s degrees in Aerospace Engineering from Princeton University. He is a member of the District of Columbia Bar and the Lawyer-Pilots Bar Association.
