Boeing on Sunday said some of its 737 planes, including many 737 Max aircraft, may have faulty parts on their wings. It's the latest problem Boeing faces as it tries to get its most important and popular airplane, the grounded 737 Max, back in the air.Working with the Federal Aviation Administration, Boeing said it has reached out to airlines that fly 737 planes, advising them to inspect their slat track assemblies on Max and NG aircraft. The 737 NG series includes the 737-600, -700, -800 and -900 planes.Leading edge slats are an aerodynamic control surface that extend from the front of the wing. Some the tracks may not meet manufacturing standards and may need to be replaced, Boeing and the FAA said. They said if the parts are found to be defective, airlines should replace them before returning the planes to service.The faulty parts could fail prematurely or crack. The FAA said a part failure would not bring down a plane, it could damage an aircraft while in flight.Boeing has sent out a service bulletin and the FAA will issue an airworthiness directive requiring airlines to inspect and repair its slat track assemblies within 10 days.The company discovered the problem Friday, when Boeing was meeting with the parts supplier. Boeing employees noticed some of the parts were not heat treated, which led them to believe there might be a safety issue.The development comes as Boeing seeks to get the 737 Max back in the air. The plane was grounded worldwide after a fatal crash of an Ethiopian Airlines jet in March, which followed a fatal crash of a Lion Air jet in Indonesia in October. Crash investigators have focused on an automatic safety feature on the jet as a possible contributor to the crashes.The newly discovered issue affects 148 slat tracks produced by a single supplier, Boeing said. The company said it believes 20 737 Max and 21 737 NG planes may have defective slat tracks. But the FAA advised airlines to check an additional 179 Max planes and 133 NGs to determine if there parts are also faulty. Of the group that needs to be inspected, 33 Max and 32 NG planes are in the United States.The company and the FAA said it has not been notified of any incidents related to the tracks on operating flights, and the fix should take a couple days to complete."We are committed to supporting our customers in every way possible as they identify and replace these potentially non-conforming tracks," said Kevin McAllister, CEO of Boeing Commercial Airplanes, in a statement. 2512

As President Donald Trump continues to make clear that he wants to kill the Affordable Care Act, new research suggests that a big part of the ACA -- the expansion of the Medicaid program -- was linked with fewer cardiovascular-related deaths in counties where expansion took place.Between 2010 and 2016, counties in states where Medicaid expanded had 4 fewer deaths per 100,000 residents each year from cardiovascular causes after expansion, compared with counties in non-expansion states, according to the research. The findings were presented at the 564

AT&T announced this week that its streaming TV service DirecTV Now has increased prices and reduced its offering of channels.When the service launched in late 2016, it was seen as an affordable alternative to cable. For those who signed up for the service in its early days, a monthly fee was good for nearly 100 channels. But the service's launch was plagued by sluggish and inconsistent service. But starting in April, the pricing and number of offerings will change. The cheapest option for DirecTV Now will be the DirecTV Now Max package, which offers 40 channels for a month. For more, consumers get 10 added channels, which includes Cinemax and regional sports networks. DirecTV Now's price increase is part of a trend of streaming services increasing prices. 793

B. Don Russell wasn’t thinking about preventing a wildfire when he developed a tool to detect power line problems before blackouts and bigger disasters.The electrical engineering professor at Texas A&M University figured he might save a life if his creation could prevent someone from being electrocuted by a downed live wire.But fire prevention may be his product’s biggest selling point in California and other places that have experienced devastating wildland blazes blamed on electrical equipment.“If we can find things when they start to fail, if we can find things that are in the process of degrading before a catastrophic event occurs, such as a downed line that might electrocute someone or a fire starting or even an outage for their customers, that’s kind of the Holy Grail,” Russell said.The technology he bills as a one-of-a kind diagnostic tool called Distribution Fault Anticipation is now in use in Texas and being tested in California by Pacific Gas & Electric Co. and Southern California Edison. The utilities have been blamed for some of the most destructive and deadliest fires in California.Texas A&M said the technology will also be tested in New Zealand and Australia, which is currently reeling from destructive wildfires.The tool detects variations in electrical currents caused by deteriorating conditions or equipment and notifies utility operators so they can send a crew to fix the problems, Russell said.It can anticipate many problems in their early stages — sometimes years before they cause an outage or present a greater hazard during high winds when utilities are now pre-emptively shutting off power to prevent sparking wildfires.Before the technology was developed, electric companies often didn’t know they had a problem until there was a failure or a customer called to report sparks on power lines or a loss of electricity.“The assumption the utility has to make today is it’s healthy until we get a call that says somebody’s lights (are) out,” Russell said. “By then the fire’s started or the outage has happened or the person’s electrocuted.”Pedernales Electric Cooperative Inc. that serves about 330,000 customers outside San Antonio and Austin, Texas, began implementing the system after successful tests that began in 2015. The utility serves areas so rural that before the technology was installed, electricity powering a pump on a well could have been off for days before being detected by a farmer.The devices installed at substations are now trouble-shooting all kinds of problems, said Robert Peterson, principal engineer for the utility.“We’ve found tree branches on the line. Failing arrestors. Failing capacitors. Failing connections,” Peterson said. “It’s pretty amazing.”In California, the testing process has just begun and there are no results yet, according to PG&E and SoCal Edison.In Southern California, the software is running on just 60 of Edison’s 1,100 circuits in the utility’s high-risk fire zone, which accounts for about a quarter of its total circuits.It’s just one of several tools the utility is testing to continue to modernize its system.“There is no silver bullet,” said Bill Chiu, managing director of grid modernization and resiliency at SoCal Edison. “This is really more of a preventive measure. ... The important point is this will be one of the suite of technology that will help us better assess the condition of the grid.”Chiu said the technology was not at the point where it could be used to determine where to shut off power when dangerous winds are forecast during dry conditions. He also said it won’t pinpoint problems but can help dispatch crews closer to the source of equipment that needs to be fixed, saving time that would be wasted patrolling miles of power lines.One question is whether the technology is economically feasible to deploy across tens of thousands of miles of power lines, Chiu said.At an expense estimated between ,000 to ,000 per circuit, it could cost the utility million in its high-risk fire area and that doesn’t include installation, operation and maintenance costs.That’s a fraction of what a moderate wildfire sparked by a utility could cost, Russell said.PG&E, which is testing the technology on nine circuits, was driven into bankruptcy protection this year while facing at least billion in losses from a series of deadly and destructive wildfires in 2017 and 2018.SoCal Edison recently agreed to pay 0 million to local governments to settle lawsuits over deadly wildfires sparked by its equipment during the last two years. That figure doesn’t include lawsuits by thousands who lost their homes in those fires or family members of 21 people killed when a mudslide tore down a fire-scarred mountain. Two other people were never found.Bluebonnet Electric Cooperative found the cost was feasible and has installed it on about a sixth of its circuits for the utility that has about 100,000 customers in Central Texas, said Eric Kocian, chief engineer and system operations officer.While the system has helped proactively diagnose problems and detect the cause of outages, the university team that developed it can often find problems the utility’s control room operators don’t detect.Pedernales Coop is working with an analytics company to streamline the analysis of the myriad information the software evaluates to find and fix problems in a day, Peterson said.Russell said he never had a hint the device his research team created 15 years ago would have fire prevention applications until a series of bad wildfires in Texas in 2011. They were focused on keeping power systems safe and the lights on.“It’s obvious now in today’s context of the drought that we’ve had in California and other places,” Russell said. “Serendipitously, that’s where we find ourselves today.” 5838

As emergency crews pick through the charred remains of Notre Dame cathedral's ancient wooden beams, which turned the world-famous site into an inferno on Monday night, focus has turned to the investigation into how the blaze started.Thirty employees working at the Paris landmark before the fire broke out were interviewed by Paris prosecutors on Tuesday, the Paris prosecutor's office said. They included construction workers and Notre Dame security staff.Interviews will resume on Wednesday, the prosecutor's office said, adding: "Investigations continue to search for the truth and identify the origins and causes of the fire."On Tuesday, prosecutor Remy Heitz told CNN the cause of the fire was "likely accidental," and that "nothing shows that it's an intentional act."He said police were interviewing witnesses to ascertain what happened. Scrutiny appears to have fallen on the firms undertaking the renovation of the 150-year-old spire, which collapsed Monday as the flames raged around it.The fire was extinguished early Tuesday after nine grueling hours, but not before the cathedral's roof had fallen in.Two policemen and a firefighter -- one of 400 fire personnel deployed to tackle the blaze -- were injured during the operation.French Junior Interior Minister Laurent Nunez said Tuesday that experts had identified "some vulnerabilities" in the fabric of the building following the devastating fire.Relics and artwork rescuedSecurity guards at the 850-year-old cathedral first heard the fire alarm at 6:20 p.m. local time on Monday, and evacuated the cathedral even though they didn't see any sign of fire, a spokesman for the Paris Fire Brigade told CNN.The alarm sounded again some 20 minutes later, at which point the cathedral's security officers noticed the fire, Paris prosecutor Remy Heitz said.Despite the rapid spread and intensity of the fire, authorities announced that some of the cathedral's major relics, artifacts and artwork had been rescued. Some of the most valuable artworks are being held at City Hall, while a number of other pieces are being transferred to the Louvre museum.The Crown of Thorns, believed to be a relic of the passion of Christ, and the Tunic of Saint Louis were among the venerated artifacts saved, Paris Mayor Anne Hidalgo said.The copper rooster that sat atop the spire which collapsed in Monday's blaze has been recovered intact, according to the French Ambassador to the United States Gerard Araud. It "contains relics for the protection of Paris," including a spine from the crown of thorns and relics of two Parisian saints, he said on Twitter.French newspaper Le Parisien, citing a source from the Ministry of Culture, said it was as yet unknown if the relics had survived the blaze.Outpouring of supportThe show of emotion in the French capital and around the world has been heartfelt.Hundreds attended a vigil Tuesday evening to grieve and sing hymns in tribute to the fire-ravaged cathedral, gathering in Paris' Place Saint-Michel square, a stone's throw from the devastated cathedral, after marching from the Church of Saint-Sulpice.Most French political parties have suspended their European election campaigns, including French President Emmanuel Macron's La Republique en Marche party.Meanwhile, donations towards the restoration have been rising steadily; the total raised so far for the reconstruction of the Gothic masterpiece has topped 800 million euros (4 million), including gifts of tens of millions of euros from some of France's wealthiest families.French billionaire Bernard Arnault, chairman and CEO of luxury good consortium LVMH, pledged 0 million, adding to a purse of million promised by the city of Paris.Cosmetics company L'Oréal, along with The Bettencourt Meyers family and the Bettencourt Schueller Foundation, has donated 200 million euros (6 million) to help fund the repairs.Difficult, costly rebuildThe Vatican's Cultural Minister has said the Vatican will offer technical know-how on rebuilding the cathedral, one of Paris' most recognizable landmarks and a symbol of French identity."We have the type of know-how that the whole word recognizes as being of high quality," Cardinal Gianfranco Ravasi told reporters. "So I think an eventual future offer by the Holy See will be significant."The full restoration of Notre Dame Cathedral will take "ten to fifteen years", according to the head of the Group of Companies for the Restoration of Historic Monuments, Frédéric Létoffé.Speaking at a press conference in Paris on Tuesday, he said that the site would need to be secured before any restoration work can take place.But the reconstruction of the cathedral, whose foundation stone was laid in the 12th century, could be hindered by a lack of suitable materials.According to Bertrand de Feydeau, Vice-President of the French Heritage Foundation, there are no trees in France large enough to replace the ancient beechwood beams that burned in the fire. 4968
