Overall quality has gone down over the last 20 years, both in metallurgy and heat treatment. This has been driven by a shrinking market and a drive by companies to buy cheap instead of buying quality. My suspicion, if an apples to apples comparison was able to be made, is that overall costs have gone up because drill steel life has gotten so bad.<br /><br />I can easily see this across our economy. The acceptance of repeatedly purchasing cheap disposable junk from places like Walmart instead of spending money once for quality. <br />Mathttps://www.blogger.com/profile/07539193399759840787noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-1735738496170921532017-09-08T15:10:13.301-07:002017-09-08T15:10:13.301-07:00If I had to guess, since this has been happening a...If I had to guess, since this has been happening across all airframes and happening more and more as time goes by, we are looking at the maker of the systems thinking that they could get away with swapping in cheaper parts. Maybe they started going with buna o-rings instead of viton. Maybe they found a cheaper source of steel/aluminum. Maybe they didnt want to spring for Inconel anymore. Companies do this sort of thing all the time once they have locked in their customer base. This is Dow Corning making Pyrex from tempered glass instead of borosilicate and saying all the shattered dishes are in our heads.

Although my old man LOX experience tells me I would NOT want to breath air (O2) that started as jet engine bleed air if I had a choice...Something about that basic design is counter intuitive..<br /><br />Are the pilots over reporting about PA (physiological episodes)? You betcha and I would too if I was still flying...Only the "squeaky wheel in this new millennia Navy gets any grease"......Am I right?<br /><br />Now on the operational side (F-18 all, T-45, T-6 Texan) we have an experienced CARRIER AIR GROUP CAMMANDER(CAG), an O-6 destined for flag officer, who happens to be a woman, leading, what we used to call a PAT team, to solve the issues (there are many), and get this public affairs nightmare to "lie down" as they call it nowadays. YO- This is the best we have to pull the resources together to solve it. BTW, IMO, the root causes are lack of "quality maintenance- O-I-D", poor system knowledge and real lack of technical capability to isolate/troubleshoot... It's got to be, fundamentally the same OBOGS has been used on Hornets and F-16's since the early 1990's..<br /><br />Now let us turn, to VADM Winter's "brain fart" for that is what it is. He is partially correct in some of his points technically and his frustration shows, though that is not the way to handle "customer relations".... BTW, he also is one of those AEDOs (not a real line officer aviator) you hear me always bringing up. His entire operational experience is one 3 year tour as a BN in the A-6E before it retired.. Ever since he has been in acquisition, .... That initial sea tour tour was probably 25 years ago. Also, the A-6 used LOX- let that sink in now.... <br /><br />Personally, I don't think he is the person to describe the color or condition of the kettle or the pot...<br /><br />CNOPs- Look at the congressional hearing yesterday- The VCNO went to provide testimony on the 7th fleet ship incidents in a Mea Culpa appeal... He is a career P-3 pilot only without a ship/CV/tour anywhere in his 30 years.. Never been a watchstander at sea, an OOD or TAO, forget about a CO tour or even a Staff (CSG, numbered fleet, etc.) tour on afloat command.. <br /><br />I rest my point and buttress yours.. about leadership.<br /><br />b2<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-16352390158855892002017-09-08T08:07:06.969-07:002017-09-08T08:07:06.969-07:00Maybe just me since I'm a F35 critic but why t...Maybe just me since I'm a F35 critic but why the hell are pilots stuck in a F35 cockpit for 30 minutes or more?!? Going thru the checklist?!? or clearing faults?!? I thought this was 1 or 2 buttons to push, start the engine, ask for clearance and take off!!! Plus, with all the sim time, not knowing the systems doesn't apply, this isn't the 50s where some guy just walked up to a plane he never flew before and some other pilot gave him the rundown and wished him luck, why are they taking so long?!?NICOhttps://www.blogger.com/profile/14567491909555759918noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-53139914082942970962017-09-08T07:08:55.942-07:002017-09-08T07:08:55.942-07:00Your point is excellent.

I admit I'm baffled by the lack of relevant data collection given the plethora of medical/chemical tests and test equipment available in the civilian world. As you say, there is no need for it to be combat or g-force rated for the purpose of investigations.<br /><br />Good comment.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-57459507530418721872017-09-08T06:54:59.441-07:002017-09-08T06:54:59.441-07:00Quite right!

And I bet they have one you could affix to an ear or a toe that would be less invasive. <br /><br />Then you have real data. OBOGS alarm went off. Pilot is saying he's woozy. Pulseox says that his O2 is low (or not). <br /><br />Maybe they do this. I'm not sure. But it seems like the testing is all on whether the OBOGS is running well; which is really only half of the equation.

Did no one notice the false positives? Did the pilots not panic in response to the false positives as the Navy is trying to claim that they do now? Do we really believe that every case of hypoxia is psychosomatic? If so, we apparently have a Navy an Air Force filled with panic-prone pilots. Are these really the guys we want flying combat? What will happen when they get a threat warning? Will they immediately panic and bail out?<br /><br />OR, IS THE NAVY COVERING UP THE PROBLEM AND MAKING SCAPEGOATS OUT OF THE PILOTS?ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-77500223957895273962017-09-07T16:20:33.834-07:002017-09-07T16:20:33.834-07:00False positives are a real problem in many health-...False positives are a real problem in many health-related fields, specifically for ailments where the symptoms of the phenomenon itself are similar to the psychological effects of suspecting it. This is why every new medicine is tested in a double blind procedure. It's not just a USN idea, the placebo effect is real and well documented.<br /><br />Also, reducing false positives is a good move regardless of the actual flaws of any system- being able to trust your fault indicators is perhaps more vital than the reliability of the system itself.<br /><br />WRT the "inexperienced pilots" section, it does seem to be a CYA statement.Anonymousnoreply@blogger.com
