After four years Air Force “confident” it has found F-22 problem source

By Larry Shaughnessy

An imperfect valve, a filter meant to protect pilots from chemical and biological threats, and decades-old vest technology combined to cause problems that grounded the state-of-the-art F-22 fighter jet, according to Air Force Maj. Gen. Charles Lyon, director of operations for Air Combat Command.

"We determined with confidence the source of the unexplained physiological incident resides in the F-22 cockpit," Lyon said.

The Air Force has been investigating why a number of F-22 pilots have experienced a mysterious loss of oxygen while in the air, causing dizziness and confusion known as hypoxia, since spring 2011. Oxygen problems that have caused hypoxia-like symptoms in pilots and ground crew members have occurred for the past four years.

In recent months, Air Force officials, under pressure from Congress and Secretary of Defense Leon Panetta, have searched for a root cause of the problem and have thoroughly examined the system as a whole and found what they believes is the cause.

"In the end there is no smoking gun," Lyon told reporters at the Pentagon Tuesday during a briefing laying out the details of the findings.

The Air Force found four main components to the cause of the problem:

- The upper pressure garment, or vest, that the pilots were wearing

- The oxygen-delivery hoses on the vest

- The valve in the quick connection point in those hoses

- An air filter on the hoses designed to filter out chemical and biological agents

The Air Force had checked each of those parts of the system independently and they all worked as expected. But only once had the service checked the entire system together.

"There was a rudimentary testing that was done on the vest and it said that it inflates early and that it impedes the mobility of the pilot in the cockpit, and that was it. They didn't study the long term physiological impact of having this inflated," Lyon said.

After that rudimentary test was done, the entire F-22 fleet was grounded, but is now flying with limits on how high the planes can fly and how far from a safe landing strip they can go.

Some critics had blamed the dangerous chemicals on the plane's exterior that help make it stealthy to enemy radar, but the Air Force ruled that out.

"How did we eliminate contamination as the root cause? We did this through months of exhaustive testing on flight tests and line operational aircraft. We poured over aircraft involved in incidents. We analyzed thousands of samples of gases, volatile and semi-volatile compounds, solids, liquids and particulate matter. We compared these samples to occupational hazard standards and we checked the levels in incident aircraft and pilots against non-incident aircraft and pilots - we found nothing remarkable," Lyon said.

Blaming the vest and the attachments doesn't answer why six ground maintenance crew members, who don't wear the vest, complained of hypoxia-like symptoms, including dizziness and lightheadedness.

Lyon blamed hunger and thirst.

"If you haven't eaten normally or you haven't fully hydrated, those type of things can begin degrade your personal performance," Lyon said. "These folks had some of these symptoms, which are ambiguous for other things that could happen to them so they reported based on that so there's a chance their diet wasn't right that day, they didn't have the hydration level that they needed."

Lyon also said some of them may have been sickened by exhaust from the jets they were working on.

As for the F-22's future, the hoses, filters and vests will be redesigned before the F-22 returns to fully operational status.

But Lyon warned that the problem will never be entirely solved. "There will be physiological incidents in the future in the F-22 and other aircraft - that goes with the territory of high performance fighter aircraft and flight operations."

El GL06-LL es un modelo que la policía compró el año pasado al precio de 1.800 euros la unidad para tener una alternativa al lanzamiento de las pelotas de goma y con el argumento de que al no rebotar no había tanto peligro de hacer daño.

    Seems like nobody here has heard about the real culprits: the pilot's air supply system, and the fuel additive TCP, a neurotoxin infamous for its use in adulterating alcohol-based medicine (Ginger Jake) during the Prohibition, which killed and paralyzed many people. This accounts for ground personnel, not just pilots, being affected. See WMR.

    This is bleeding edge technology and very complicated when all these systems and methods get combined into a self propelled unit with a pilot at the controls. We're not going to get the details because of security considerations. What we will hear has been through many filters to make sure the words and music are "correct" for public consumption. With tensions high in the world the F-22 might just have its chance to prove itself in actual combat. These problems will be solved and that's how technology advances.

    The Air Force investigation of the problem is inconclusive, incomplete, and hopefully not finished. The real story is about what you get when they are pressured by politicians who have no clue of or appreciation for the complexities of the technology. The Air Force simply gave them a quick answer in terms of something they could understand. Only time will tell if the redesigned vest is the answer obviously, since future O2 problems either will or will not occur, doh.

    Are you serious @Smoking Gun? We don't need a next generation fighter? How blind can you liberals be??... Both China and Russia have equivalent fighters. Maybe we should just drive F15 and F16s around and let other countries rule the world with superior air power. I'm sure Poland thought investment in military was stupid too, then Germany face stomped them and laughed the whole way. I can't stand how dumb anti-military people are. The world is not a 'Nice' place, you have to protect yourself, and the best way to do that is have bigger and better technology. It IS a priority.

    I say to solve budget issues we get all of the people off social security and disability who are actually fine and able to work. They all voted for Obama for a reason. You ever been down south and saw how many worthless people live off the government and are 200% obese? Whats wrong with that picture? Maybe 1% actually WANT to work. Prime example of government hand outs to people who are unwilling to be anything other than worthless.

Yeah lets just get rid of the F22, and all our modern aircraft and go back to flying Sopwith Camel By-Planes to defend our nation. The U.S. wouldn't last a year. The F-22 is the most advanced fighter jet ever built, and the U.S. has a very small number of these jets. Even with the few F-22s that we have the U.S. could take out the entire airforces of any other nation on this planet. Why do we need these? As I said before, the BEST offense is a good defense.

        If it wasn't for those types of people, you wouldn't have a purpose in life. If you look at land around a lot of military bases, or military range, you'll see all kinds of wildlife. Protection of animals on bases and ranges is far more strict (even though we drop bombs on ranges and stuff). We have people from the EPA ensure we follow all kinds of rules. Compare this to any place else other than a dedicated wildlife refuge and you'll find that wildlife is actually protected (indirectly) thanks to the military.

    So the problem with the F-22 a plane that costs billions has been solved? Can anyone offer a logical explanation the mentality that we have to constantly upgrade our weapons systems when the ones we now have are far superior to any other in the world? On the drawing boards somewhere and right now, some large firm and the USAF are developing a fighter plane that will exceed the F-22's capabilities. Nice but even though we do not need it, we are spending billions on this newer version.

      I'm a raggedy ole Navy aviation veteran from the 'Nam era and ALL of our aircaft are designed looking ahead and taking decades. The F-14 started design in the early '60's and it was only with the stealth technology that made the F-22 and F-35 actual realities instead of an aeronautical engineer's dream. It's the price you pay for staying ahead. As we learned during the Cold War, playing Catch Up is a very scary proposition.

        Well said on the need to stay ahead. Using the logic of some idiots here we would be "sending kids to die" in 79's era aircraft . It always amazes me to hear this endless, ill informed, carping about the need for development of leading edge military technology. Those same people would be screaming long and loud without that same leading edge technology at the ready to defend their right to carp about the technology.

        To all the wise men who KEEP saying that thte F15 has been phased out WRONG WRONG WRONG. I read this yesterday and I see it here again. Ifyou are gonna put information out put out CORRECT information. THe F15-C & E models continue in service and will continue. The F-22 was suppposed to be built in numbers around 750 to replace the F15-C but that is not gonna happen now that F-22 production has been stopped @ 175 ships.

        As a former engineer in the employ of the company that built the engines for the F14 / F15 /F16 and now the F-22 and F-35 I wish the same people who enjoy the security provided by our military would just shut up and let the military do their job w/o all the incorrect information and back seat driving these civilian experts spew out about things they don't understand!

      You really should read up on the subject before commenting. We sell our surplus military equipment around the world. That means their are LOTS of countries out there with F-15s and F-16s. Drones are not yet to the point of air-to-air combat fighter jet. Both Russia and China have respectable even comparable aircraft.

      Who says that the cannot put the same radars on the drones, resulting in a smaller, more agile attack aircraft with a significantly smaller radar cross section without the use of more expensive radar absorbant materials? You points are not valid and the only thing a piloted aircraft can do better than a drone is allowing the operator to have a much high level of situation awareness. The force of the future will use a few manned planes and a lot drones.

        If you want to have a drone with the capabilities of a modern fighter, I'd be willing to bet the cost will be about the same. Cost of contractors, maintainers and parts would be about the same. If there are drone pilots or some sort of crew at a ground control station, that would cost the same as pilots. And if our contractors try and squeeze every bit of money out of us, I think they could make it more expensive.

      It is dismissive because it is worthy of being dismissed. Aircraft maintainers work their hands to the bone (figuratively of course) and in all likely hood it has nothing to do with this airframe. I'm sure they merely found the incidents because of the investigation, and if they thoroughly checked maintainers for every other airframe they would find a higher incident rate for more difficult aircraft to work with. Ever fix up a B-52? Didn't think so.

        Exactly! those ground crews experience those symptoms every month, and have been experiencing those symptoms every fourth plane they work on – just it was confidential information on a need to know basis since the 1920s, so we're coming clean on it now....

    They have a chemical warfare filter in the air passage, and no one thought to check if that was the cause until now??

    That's hard to believe. That filter should have been an obvious suspect to anyone with even a cursory knowledge of the system design.

        The filter works perfectly by itself – see, the filter closed, and NO air gets through, and when the filter is open, NO air gets through – it couldn't possibly cause hy-pox-ia since pox was eradicated centuries ago. 🙂

      ... You read a different article? The article says the filters and other components will be redesigned. Such filters often greatly reduce and obstruct airflow and also have extremely limited lifetime before becoming clogged. This failure should have been absolute obvious to anyone familiar with the system. This gives me great pause about the skills and abilities of the people both designing and maintaining the hardware.

    Correlation does not equal causation. If the ground crews were experiencing hypoxia caused by the F-22, it's wrong to assume the hypoxia experienced by the pilots has the same cause. Maybe the ground crews were being affected by toxic fumes and the pilots were being affected by defective flight suits. However, in my opinion, none of the explanations offered by theorists or the government itself satisfactorily explain this mystery.

    fred37ify might have the answer here. If the performace of the plane puts it in the category of something like the SR-71, maybe the pilots should wear the same suit as the SR-71 pilots to handle the stress. The SR-71 pilots wore full astronaut gear.

    I built these things, okay? Most layman simply have NO idea about the capabilities of this aircraft. Frankly, it is easily capable of exceeding the physical limitations of human pilots. What you don't hear much about is the dozens of pilots who love this aircraft and have had ZERO issues with the hypoxia-like symptoms experienced by some. These same conditions have been experienced by fighter pilots since WWI...some guys simply have a higher tolerance to the forces and physical demands of flying a fighter than others. I agree this 'fix' is pretty convenient, but it is easier than simply admitting some of the pilots are not cut out to fly the plane. Most all of these guys have already taken to flying other aircraft, no harm..no foul. Hell, none of us would last TWO SECONDS in the seat of one of these things...lol!

      Building F-22's doesn't mean you know the first thing about flying one. I flew F-14's. There are many, many fighters capable of exceeding the physical limitations of the crew. There is nothing special about the F-22 that puts it in any higher risk category than many other fighters. Hypoxia and G-LOC (G-induced Loss Of Consciousness) are two separate issues and pilots are trained to know the difference. Most of the current F-22 pilots transitioned from other fighters with similar maneuvering capabilities, so your point about not being cut out to fly the plane is incorrect.

    An explosive Congressional investigation revealed horrific new details this week about a U.S. funded military hospital in Afghanistan that kept patients in "Auschwitz-like" conditions.

    The investigation also revealed that Lt. General William B. Caldwell, then commander of the $11.2 billion dollar a year Afghan training program, tried to block the probe and ordered a cover-up.

    There are currently two ongoing investigations looking into the Dawood Military Hospital abuses: one centered around the Military Whistleblower Protection Act, the other concerned with Caldwell’s politically-motivated decision to delay investigations into the hospital until after the 2010 elections.

    What follows is a very disturbing look inside the Dawood National Military Hospital. It was compiled with sworn eye-witness testimony from the three U.S. Army colonels who blew the whistle on the scandal, as well as never-before published photos obtained by BuzzFeed.

    The photos and corresponding descriptions were collected by U.S. military personnel in Afghanistan.

    So, they found the system...as a whole...isn't the sum of its parts. Okay, that's fine. Then, since that didn't account for the ground crew, they made up some other silly answer. In truth, I still don't believe they KNOW anything concrete, but they need to put on a good show. It is possible that several little things merge to create the problem, and, in fact, that's a likely situation. However, since this doesn't account for the ground crews experiencing the same conditions, they're saying it's two different things...one of which we can't quantify at all.

    This is a mess, and at the risk of making it messier, to me this sounds like a certain Presidential campaign, that attempt to spin everything with the hope that you won't notice there's nothing really there in the first place.

      I suspect the ground crew who claimed hypoxia like symptoms were probably suffering from dehydration as the SecDef states. A lot of servicemen love drinking about 50 gallons of monsters and redbulls a day, smoke and don't eat. I've also seen some try to get out of physical fitness by claiming all kinds of lame crap.

        Wrong! The F-22 program is being ended because the plane itself is ineffective in the anticipated mission environment of future wars, having no designed air-to-ground capability. All the aircraft received have been paid for in full and any future funds allotted to the F-22 program are for maintenance and upkeep.

    This result seems somewhat suspect to me. The article states that the vests are decades-old technology. It follows that these vests are used in other fighter planes. Are the hoses, connections and filters newly designed?

    If they are not, why aren't these complaints happening with the F15? If they are, that should be a central point made in the published result, which I don't see in this article.

      No. They will fix this problem, but he is saying there will always be similar types of issues.

      When you maneuver at 4, 5, or higher Gs, then all the blood will rush out of your head or to your head. The vest and other systems compensate for that, but they do not totally eliminate that. The human body is conditioned to operate at 1 G, when you change that environment, there are consequences that no amount of money will solve.
