News Release: NTSB Issues 3 Safety Recommendations Following Investigation of Rollover Bus Crash

​WASHINGTON (June 3, 2021) — The National Transportation Safety Board issued three safety recommendations Thursday with its final report on the agency’s investigation of the fatal Sept. 20, 2019, rollover bus crash near Bryce Canyon City, Utah.

In its safety recommendations the NTSB asks the National Highway Traffic Safety Administration to:

-Require lane departure prevention systems on new commercial motor vehicles with gross vehicle weight ratings above 10,000 pounds.

-Require all new buses, other than school buses, with a gross vehicle weight rating above 10,000 pounds to meet a roof strength standard that provides maximum survival space for all seating positions.

-Require all new buses, other than school buses, with a gross vehicle weight rating above 10,000 pounds to meet a window glazing standard that prevents occupant ejection.

In Highway Accident Report 21/01, the NTSB also reiterated five previously issued safety recommendations, including two concerning stability control systems for commercial vehicles, and classified five others as “Closed – Unacceptable Action/Superseded.”

The crash happened when the medium-size bus was traveling east on Utah State Route 12, operated by a 60-year-old driver and carrying 30 passengers during a trip from Los Angeles to Salt Lake City. At a recorded speed of 64 mph (in a posted 65 mph zone) the bus’s right wheels departed the right edge of the roadway. The driver steered left, and the bus went into the westbound lane. The driver then steered sharply to the right, causing the bus to become unstable. The bus then rolled 90 degrees onto its left side, sliding for about 85 feet until its roof struck the guardrail, rolled over the guardrail and came to rest on its wheels, straddling the damaged guardrail. The crash killed four passengers, 17 others suffered serious injuries, nine more suffered minor injuries, and a total of 13 of the 30 passengers were ejected from the bus. The driver was not injured.

The NTSB determined the probable cause of the crash was the driver’s failure, for undetermined reasons, to maintain the bus within its travel lane, and his subsequent steering overcorrections, which caused the bus to become unstable and roll over. Factors that contributed to the severity of the crash include:

-The bus roof’s deformation and collapse, which created ejection portals and compromised passengers’ survival space.

-The National Highway Traffic Safety Administration’s failure to develop and issue standards for bus roof strength and window glazing to enhance the protection of bus passengers.

The lack of passenger lap/shoulder belts on the bus contributed to the ejections and the severity of injuries.

NTSB investigators determined driver experience, licensing, alcohol or drug use, fatigue, distraction, and/or medical issues were not factors in the crash, nor was the mechanical operation of the bus. Similarly, highway design, markings, signage and friction characteristics of the highway were not considered as factors in the crash. Motor carrier operations and state or federal oversight of the motor carrier, America Shengjia, were also ruled out as factors in the crash.

“This crash highlights the role that technology can play in preventing bus crashes,” said Rob Molloy, Director of the Office of Highway Safety at the NTSB. “A lane departure prevention system could have kept this crash from happening by keeping the bus in its travel lane. An electronic stability control system could have helped maintain the bus’s stability during the driver’s steering overcorrections, preventing the bus rollover,” said Molloy.

News Release: Medical Incapacitation Led to Fatal I-75 Crash

​WASHINGTON (May 27, 2021) — The National Transportation Safety Board said in a report issued Thursday that the medical incapacitation of an Eagle Express truck driver led to the fatal, Jan. 3, 2019, multi-vehicle crash on I-75 near Alachua, Florida.

NTSB Highway Accident Brief 21/01 states the truck driver’s incapacitation resulted in his failure to maintain his travel lane and led to the truck crossing the highway’s center median and colliding with several vehicles in the opposite lanes of travel. Evidence from the roadway, dashboard camera and witness interviews suggest the driver did not attempt evasive action as the truck veered across the median and into oncoming traffic. The crash resulted in seven fatalities and injuries to eight others. The crash involved five vehicles.

Autopsy results identified “ischemic heart disease” as a contributing factor in the truck driver’s cause of death, however, the truck driver had a number of medical conditions and used medication that could also have caused incapacitation.

During his most recent medical certification examination, the driver did not disclose all his medical conditions nor all the medications he was taking. The failure to disclose his conditions to medical examiners led to his receipt of medical certifications valid for the maximum of two years each. NTSB investigators noted that had the driver disclosed his relevant health information it may have resulted in a shorter medical certification period, but it would not have predicted his incapacitation on the day of the crash.

NTSB investigators determined the Eagle Express truck, a 2016 Freightliner with a 2018 Vanguard semitrailer, had no apparent defects that would have led to the crash. Analysis of maintenance records and a search of the safety recall database and related records showed no factors relevant to the events in this crash.

Highway Accident Brief 21/01 is available online at http://go.usa.gov/x6apS and the docket, which contains 73 items, is available at https://go.usa.gov/x6adx.

News Release: Investigative Update: Wednesday's Mid-Air Collision Near Denver

​WASHINGTON (May 13, 2021) — National Transportation Safety Board investigators continue Thursday to gather information about Wednesday’s mid-air collision involving a Cirrus SR-22 airplane and a Swearingen Metroliner airplane near Centennial Airport, Denver.

No one was injured when the Swearingen Metroliner, operated by Key Lime Air, and a Cirrus SR-22 rented, from Independence Aviation, collided as the planes were landing at Centennial Airport.

The NTSB Investigator-in-Charge for this accident has interviewed both pilots, and an NTSB air traffic control specialist has listened to recordings from air traffic control. Interviews of the controllers working with the Cirrus and Metroliner pilots are planned.

An NTSB investigator examined the wrecked Cirrus Wednesday and will examine the Metroliner Thursday. The insurer of the Cirrus arranged for removal and transport of the plane to Centennial Airport and the Metroliner is at a Key Lime Air facility at Centennial Airport.

Both aircraft were operating under Part 91 general aviation rules. The Cirrus was on a local flight from Centennial and the Metroliner was repositioning from Salida, Colorado.

The NTSB’s investigation of the mid-air collision will, in general terms, look at the people involved in the accident, the airplanes involved in the accident and the environment in which the accident happened. There are currently four NTSB investigators working on this accident investigation.

“We are working to understand how and why these planes collided,” said John Brannen, a Senior Air Safety Investigator from the NTSB’s Central Region office and the Investigator-in-Charge for the accident investigation. “It is so fortunate that no one was injured in this collision.”

A preliminary report will publish in the next 14 days and the investigation is expected to take between 12 and 18 months to complete.

News Release: NTSB Issues Preliminary Report for Fatal, Texas, Tesla Crash

WASHINGTON (May 10, 2021) — The National Transportation Safety Board issued Monday the preliminary report for its ongoing investigation of the fatal, April 17, 2021, crash of a 2019 Tesla Model S near Spring, Texas.

Information in the report is preliminary and subject to change as the investigation progresses and as such, no conclusions about the cause of the crash should be drawn from the report.

The report states the Model S P100D car was equipped with “Autopilot” – Tesla’s advanced driver assistance system. This system requires both the Traffic Aware Cruise Control and the Autosteer systems to be engaged. NTSB tests of an exemplar car at the crash location showed that Traffic Aware Cruise Control could be engaged, but Autosteer was not available on the part of the road (Hammock Dunes Place) where the crash happened.

According to the report the crash trip began at the owner’s residence. Footage from the owner’s home security cameras show the owner entering the driver’s seat and the passenger entering the front passenger seat. The video also shows the car slowly entering the roadway and then accelerating down the road away from the camera and out of sight. Based on examination of the accident scene investigators have determined the car traveled about 550 feet before departing the road on a curve, driving over the curb, and hitting a drainage culvert, a raised manhole and a tree.

The post-crash fire destroyed the car’s onboard data storage device and damaged the car’s restraint control module. The damaged module was recovered and taken to the NTSB’s recorder laboratory for evaluation. Restraint control modules can record data associated with vehicle speed, seat belt status, acceleration and airbag deployment.

The steering wheel from the Tesla was shipped to the NTSB materials laboratory for analysis of the damage to the steering wheel investigators observed during the post-crash inspection.

The 59-year-old owner and a 69-year-old passenger died in the crash.

The NTSB’s investigation of the crash is ongoing, and investigators continue to gather information including data to analyze the crash dynamics, postmortem toxicology test results, seat belt use, occupant egress and the post-crash fire.

News Release: Lack of Continuous Monitoring At Issue in Shipyard Fire

​WASHINGTON (May 4, 2021) – A 2020 shipyard fire aboard the Iron Maiden was able to start and spread without notice because no one was continually monitoring the vessel while fire detectors were shut off during repairs, the National Transportation Safety Board said in a report issued Tuesday.

Marine Accident Brief 21/11 details the NTSB’s investigation into the April 16, 2020, fire aboard the dive support vessel docked at the Allied Shipyard in Larose, Louisiana. The fire caused $900,000 in damage. There were no injuries.

While the fire caused extensive damage throughout the generator room, the NTSB found fire pattern and damage indicating the fire started near the forward bulkhead. Because the battery charger, alarm panel, and generator push button start-stop panel were in the area of fire ignition identified by fire investigators, an electrical short from one of these components may have been the source of the fire. However, the exact location of the source of the fire could not be identified by fire investigators.

There was no crewmember or shipyard worker staying on board the Iron Maiden during the night of the fire. The vessel’s fire detection system was shut off while work was being conducted within the vessel to prevent false alarms from smoke and dust. In addition, there was no shipyard policy or vessel owner policy in place to have shipyard personnel or vessel crewmembers conduct safety rounds after hours when there was no work being done on the vessel.

“Fire and flooding are risks for both crewed and unattended vessels,” the report said. “To protect personnel, property, and the environment, it is good marine practice for owners, operators, and shipyard managers to coordinate and implement some form of continuous monitoring for vessels undergoing maintenance in a shipyard, in lay-up, or in some other inactive period without regular crews aboard. Continuous monitoring can consist of scheduled security rounds and/or active monitoring with sensing and alarm systems.”
