Boeing says it has a software fix ready for its 737 Max airplanes that will be unveiled to airline officials, pilots and aviation authorities from around the world Wednesday, as the aircraft manufacturer works to rebuild trust among its customers and the flying public following two fatal crashes of the planes in recent months.

Meanwhile, those crashes and the relationship between Boeing and the federal agency charged with regulating it will be discussed at a U.S. Senate aviation subcommittee hearing on Wednesday. Scheduled to testify are the heads of the Federal Aviation Administration and the National Transportation Safety Board, along with the Transportation Department’s inspector general, who is investigating how the FAA went about certifying the 737 Max as airworthy, and whether regulators relied too heavily on Boeing’s own safety assessments in their review.

Those developments come as transportation authorities in Ethiopia prepare to release preliminary findings on the cause of the crash of an Ethiopian Airlines Boeing 737 Max 8 plane earlier this month that killed all 157 people on board.

A spokesman for Ethiopia’s transport ministry told The Associated Press “a date has not been set but (the preliminary report) will be released later this week.” The spokesman says the U.S. National Transportation Safety Board, France’s aviation investigative authority BEA and Ethiopia’s Transport Ministry have been conducting the investigation jointly.

The investigators have said there were striking similarities between the March 10 crash outside of Ethiopia’s capital city Addis Ababa and the crash of a Lion Air Boeing 737 Max 8 into the Java Sea in Indonesia last October. Both planes crashed shortly after takeoff and both followed similar, erratic flight tracks in the air that indicate the pilots may have been struggling to try keep the planes from going into nosedives.

In the Lion Air jet crash Oct. 29, which killed all 189 people on board, Indonesian investigators say an automated flight control system, acting on erroneous data from a faulty sensor, repeatedly forced the nose of the plane down. That system, called MCAS, for Maneuvering Characteristics Augmentation System, is designed to prevent the airplane from stalling. But the Lion Air pilots apparently did not know how to counteract the system or disengage it, and were in a futile struggle to regain control of the plane.

After the Lion Air crash, many pilots complained that had not been made aware of the MCAS system, as it did not exist on previous versions of the 737, nor had they been trained on what to do when the system engages and forces the nose of the plane downward unexpectedly.

It still is not clear if something similar happened on the Ethiopian Airlines jet but the company’s CEO says pilots had been trained on how to handle the new system after the Lion Air crash.

Boeing officials say the company has completed developing software upgrades for MCAS aimed at preventing such occurrences in the future. The system will no longer act repeatedly in forcing the nose of the plane and will act just once if detecting the plane entering an aerodynamic stall. And the MCAS system will rely on data from the two angle of attack sensors on the plane, instead of just one.

In addition, a warning light that alerts the pilot when the angle of attack sensors disagree will become standard instead of being a more expensive option for airlines to purchase, and it will be added to the entire fleet of 737 Max aircraft for free.

A Boeing official says the software upgrades have undergone extensive lab and simulator testing, with pilots in a simulator facing a series of errors and failures, including sensor errors and other erroneous inputs.

The Boeing official says the FAA participated in the evaluation, even demonstrating the software upgrades during a test flight on March 12.

It is unlikely that the FAA will act quickly in certifying the software upgrades and other fixes, especially considering the scrutiny of the certification process coming from Congress and others. And regulators in Canada, Europe, China and other countries say they will no longer rely on FAA data and will conduct their own tests of the MCAS software updates before allowing Boeing’s 737 Max planes in the air again. As a result, some experts say it could be months before the airplanes are allowed back into service.

Women Tell FDA That More Research Is Needed On Health Risks Of Breast Implants

Advisers to the FDA concluded a meeting Tuesday on the safety of breast implants. What’s emerged is a lack of scientific certainty about the risks implants pose to millions of women who have them.



AUDIE CORNISH, HOST:

Advisers to the U.S. Food and Drug Administration have spent two days focusing on the safety of breast implants. What’s emerged is a lack of scientific certainty about the risks implants pose to the millions of women who have them. NPR’s Patti Neighmond reports.

PATTI NEIGHMOND, BYLINE: The panel heard from manufacturers, plastic surgeons, researchers and women who got implants for reconstruction after mastectomy or for cosmetic reasons. Tara Huppco (ph) told the panel she was a healthy mom and bodybuilder in her mid-30s when she decided to get implants for aesthetic reasons. Problems started just weeks after surgery, when she became extremely exhausted and could no longer remember the names of colleagues at work.

TARA HUPPCO: I had panic attacks that woke me in the night and anxiety that kept me shut in in my house. My hair stopped growing. My vision was blurry. I couldn’t eat without pain and nausea. Every morning, getting out of bed, my legs were numb and my feet burned.

NEIGHMOND: Huppco was one of dozens of women to address the panel about a range of autoimmune-related symptoms, often called Breast Implant Illness. She had her implants removed about a year ago.

HUPPCO: My symptoms are almost all gone. I am the person that I used to be. And if I knew anything of what could have happened, I would have said, no, thank you to my implants.

NEIGHMOND: Like most women who spoke, Huppco implored the FDA to look more closely at safety concerns and move right away to take textured implants off the market. These implants have a bumpy surface to help them stay in place, but there’s an increasing number of anecdotal reports suggesting they cause autoimmune illness. They’ve also been linked to a very rare cancer of the immune system.

Even so, most members of the panel say there’s not enough evidence yet to rush textured implants off the market and that larger, longer-term studies are needed. Reina Doria (ph) with the implant manufacturer Mentor says the company provides patient education brochures to doctors to help patients understand potential risks of implants.

REINA DORIA: There may be a gap between what we are providing and what information is reaching the patients. We believe the best way to ensure patient understanding of risk is for them to have a conversation directly with their surgeon.

NEIGHMOND: The FDA panel is not expected to make specific recommendations about implants at this point. It is expected to call for more research into implant safety. Patti Neighmond, NPR News.

Soccer-Playing Engineer Calls Foul On Pricey Knee Brace

After a sports injury, Esteban Serrano owed $829.41 for a knee brace purchased with insurance through his doctor’s office. He says he found the same kind of brace selling for less than $250 online.

Last October, Esteban Serrano wrenched his knee badly during his weekly soccer game with friends.

Serrano, a software engineer, grew up playing soccer in Quito, Ecuador, and he has kept up the sport since moving to the United States two decades ago.

He hobbled off the field and iced his knee. But the pain was so severe that he made an appointment with Rothman Orthopaedic Institute, a network of orthopedists practicing in Greater Philadelphia, New Jersey and New York.

The doctor diagnosed a strain of the medial collateral ligament and prescribed over-the-counter pain medication as well as a hinged knee brace, which Serrano used for several weeks until he’d healed.

He expected his insurance to cover his treatment. A plan from a previous job had covered him when he needed surgery to fix a broken nose sustained in another soccer game in 2017.

Then the bill came.

Patient: Esteban Serrano, 41, a software engineer and father of two from Phoenixville, Pa., outside Philadelphia.

Total bill: $1,197. $210 for the office outpatient visit, $105 for an X-ray and $882 for a hinged knee brace, all billed by the orthopedic practice. His insurer, Aetna, negotiated only $52.59 off the cost of the brace. That left Serrano with a balance of $829.41 because he hadn’t met his $3,000 deductible for the year.

Service provider: Rothman Orthopaedic Institute in Bryn Mawr, Pa.

Medical service: A doctor examined Serrano’s knee and sent him for an X-ray. The doctor said he should use a knee brace for four weeks and recommended a hinged one sold through the practice.

What gives: A medial collateral ligament injury is a common knee injury occurring frequently among participants in contact sports. According to the American Academy of Physical Medicine and Rehabilitation, the medial collateral ligament is involved in at least 42 percent of knee ligament injuries. Although most cases are sports related, such injuries can also result from everyday activities like tripping on stairs.

“The doctor told me that he thought I didn’t have damage, that it was more of an inflammation, but he ordered an MRI just to make sure,” said Serrano. (The MRI, performed at a later date, confirmed that suspicion.)

Serrano said the brace did ease the discomfort and stabilized his knee as it healed. However, the bill was almost more painful — he owed the orthopedic practice $829.41.

“You can find the same brace for less than $250 online,” he said.

The bill came close to Christmas, when Serrano’s 12-year-old daughter wanted her first iPhone. “I told her, ‘Sorry, honey, but I already paid a price of an iPhone for the hinged knee brace,’ ” Serrano joked.

Serrano emphasized that he felt lucky to have the money to handle a bill that for many people could equal a month’s rent or three months of groceries.

Knee braces fall into a category of products called “durable medical equipment,” whose prices can vary widely. Items range from slings and braces to wheelchairs and commodes. They also include glucose meters and breast pumps for new mothers.

Doctors and hospitals that dispense such equipment for patients to take home almost always bill for them and add hefty markups that can catch patients unaware.

Braces and other products “are often marked up two or three times what the cost is, and unfortunately, that is the standard practice,” said Dr. Matthew Matava, an orthopedic surgeon and chief of sports medicine for Washington University Physicians in St. Louis.

Rothman Orthopaedic didn’t respond to requests for comments.

The type of hinged knee brace Serrano bought was a DonJoy Playmaker. DonJoy is one of the nation’s largest producers of braces. A customer service representative for the company said it charges a retail price of $242.51 for the model that Serrano got. Serrano paid more than three times that price.

In an emailed statement about the case, an Aetna spokesman wrote that “while the cost of a knee brace, or any other health care service, is determined by the negotiated rate between the health care provider and the health plan, the starting point is the charge from the health care provider.”

It is not even clear that such an elaborate knee brace was needed for Serrano’s injury.

Dr. Elizabeth Matzkin, chief of women’s sports medicine at Brigham and Women’s Hospital in Boston and an assistant professor at Harvard Medical School, said that while it is helpful to give patients some kind of knee brace for support after medial collateral ligament injuries, the use of a hinged knee brace does not influence recovery, according to studies. She called hinged braces “luxury products.” Simpler, cheaper braces also offer support.

Resolution: Serrano recalled that when he received the brace, an employee showed him a form with its estimated cost in writing. He remembered his share was more than $700, but he didn’t pay too much attention because he assumed his insurance would cover it.

After receiving the bill, he made several phone calls to the doctor’s practice to get a copy of the form he’d signed. It stated that the product could be returned within seven days. A month had already passed. Because he had not met his deductible, his $829.41 balance was even more than the estimate.

The takeaway: These days, many types of equipment dispensed by doctors’ offices or hospitals involve a charge. Don’t assume generosity. Ask the doctor to identify precisely what you need and explain why you need it.

When a doctor or hospital offers you a piece of equipment to help your healing, decide if you really need it or will use it. Say no if you won’t. Ask if you will be billed for it and how much.

Many items can be purchased at a fraction of the cost online or from a pharmacy just down the block.

Know your insurance plan’s copay or coinsurance for medical equipment (often 20 percent). The cost of purchasing the equipment yourself online may well be less than if you purchase through a medical office.
