    Crash d'un hélicopter en mission HEMS : envoi de texto en vol...

    Texting by a pilot before and during a 2011 medical-helicopter flight in Missouri contributed to its crash, the first time such distractions have been implicated in a fatal commercial-aviation accident, the U.S. National Transportation Safety Board found.

    The distraction from texting helped lead the pilot to take off without enough fuel, the investigative agency found at a hearing today in Washington. The helicopter’s engine stopped after the pilot reported that he had more fuel than was aboard, the NTSB found.

    While calling texting a contributing factor rather than a probable cause of the accident, the safety board issued a warning today to pilots about the distractions posed by using wireless devices during flight.

    “We continue to see this in multiple modes of transportation,” NTSB Chairman Debbie Hersman said. “How many people have to die before we have to say something about it?”

    The NTSB documented at least 240 texts sent and received by the pilot during his shift the day of the accident, according to records cited by Bill Bramble, an NTSB investigator. There were 20 such texts with a coworker before and during the accident, the safety board found.

    The Air Methods Corp. (AIRM) helicopter crashed in a field after running out of fuel, according to preliminary NTSB reports. Use of electronic devices by pilots during flight was prohibited by company rules, according to the reports.

    Hypothetical Reality

    “This is a classic example of dividing attention in a way that compromises safety,” said David Strayer, a psychology professor at the University of Utah in Salt Lake City who has studied how personal electronic devices cause distraction.

    This is the first time the NTSB has uncovered evidence of texting or mobile-phone use during a flight involved in a fatal accident, Kelly Nantel, an NTSB spokeswoman, said in an e-mail.

    In talks he gives on distracted driving, Strayer said he often asks people what they would think about an airline pilot phoning to make dinner reservations while approaching an airport.

    “Curiously enough, here is a situation in which that ludicrous example occurred,” Strayer said. “Now you’ve got it coming full circle.”

    Four Texts

    The company has put in place safety improvements since the accident, Mike Allen, president of domestic air medical services at Air Methods, said in a statement. Among the changes is a “zero tolerance policy” for mobile phone use during flight, Allen said.

    Air Methods, based in Englewood, Colorado, says on its website that it operates more than 300 air-medical bases in 48 states.

    The crash on Aug. 26, 2011, in Mosby, Missouri, killed Terry Tacoronte, a patient who was being flown from one hospital to another. Pilot James Freudenbert, Randy Bever, a flight nurse, and Chris Frakes, a paramedic, also died. The helicopter was being operated under the name LifeNet.

    Freudenbert received four texts, three of them from a friend at work, and sent three others during the flight, according to NTSB records. He was planning to have dinner with the coworker, according to the records.

    Another 13 texts were logged on his phone in the 71 minutes before the flight, including two during a previous flight, according to NTSB records.

    Federal Regulations

    Freudenbert, 34, who told the coworker he hadn’t slept well the night before, failed to refuel the helicopter before flying to a hospital in Bethany, Missouri, to pick up Tacorente, according to NTSB records.

    He realized his mistake after landing at the hospital and discussed where to get more fuel with a company dispatcher. He was headed to Midwest National Air Center Airport in Mosby when the helicopter went down.

    Taking off on the final flight may have violated U.S. Federal Aviation Administration regulations on how much fuel is required, according to NTSB records. Helicopters carrying passengers for hire must carry a 20-minute fuel reserve beyond what they need to get to their destination, according to NTSB records.

    Freudenbert radioed a dispatcher after takeoff that he had enough fuel to fly 45 minutes. The copter was aloft for 30 minutes before it ran out of fuel, according to NTSB records.

    Warning Light

    “I don’t want to run short and I don’t want to run into that 20-minute reserve if I don’t have to,” he radioed a company dispatcher shortly before taking off.

    The Eurocopter AS350 helicopter was equipped with a warning light to alert pilots when fuel ran low, according to the records. Freudenbert never radioed that he was having an emergency.

    The preliminary NTSB reports didn’t say why the helicopter struck the ground with such force. A powerless helicopter should be able to land safely.

    Air Methods prohibits its pilots from using mobile phones during flights, according to NTSB’s preliminary reports.

    While FAA regulations also prohibit extraneous conversation and using personal electronic devices during “critical” phases of commercial flights, it allows their use during level cruise flight.

    “It’s hard to know what to say,” Tom Judge, executive director of LifeFlight of Maine, the state’s emergency helicopter service, and an advocate for enhanced safety, said in an interview. “We’ve got to increase the level of accountability.”

    Distracted Driving

    The crash is different from what is commonly seen in distracted driving when a motorist takes his or her eyes off the road and causes an accident, John Lee, an engineering professor at the University of Wisconsin, said in an interview.

    Instead, it’s similar to an office worker who gets a phone call and forgets to send an e-mail, said Lee, who studies people’s interaction with technology. Such distractions from so- called multi tasking have been linked to medical errors, he said.

    The NTSB’s Hersman and Transportation Secretary Ray LaHood have spoken out about increasing accidents in which mobile phones and other electronic devices have led to lapses in attention.

    April is National Distracted Driving Awareness Month, LaHood said in a blog post yesterday. Text messaging raises the risk of a crash on the road by 23 times, he said.

    Use of electronic devices in the cockpit has occasionally come up in NTSB cases. The co-pilot on a Pinnacle Airlines Corp. (PNCLQ) Colgan Air flight that crashed near Buffalo on Feb. 12, 2009, killing 50 people, texted her husband while the plane was still on the ground before departure.

    There have been 13 helicopter air-medical flight accidents since 2011, killing 12 people, according to NTSB records. Three of the accidents were on Air Methods helicopters.

    le lien !
    C'est surtout un manque de pétrole !
    L'affaire des textos avant ne peut expliquer le bilan à mon avis !
    Très surprenant
