just wondering if anyone else heard of this or has anymore knowledge about the issues.

Here is a bit more information on this:

ya, kinda sux. The Eagle E model demo was cancelled at Randolph AFB this past Sunday because of the grounding. :(
-
You'd never hear of an F-16 breaking up in flight. Of course, the F-15 wasn't designed as a 9-g fighter. It was originally a 7.5g plane that at the last moment they tried to convert into a real fighter. Well at least we still have our F16 fleet to keep us safe.

ya you have you just may not remember

The F-15 that crashed Friday was 27 years old.
- From the article.
That many years of stress on parts, and something is bound to break eventually.
Hopefully from this, they can examine what part(s) in the structure failed and make adjustments.

If it was made in 1980 it was probably close to retirement. We tend to not flight jet fighters that long for this specific reason.

I just did a search, I couldn't find anything about airframe fatigue causing an F-16 crash.
-
I'll find the incidents but IIRC they occurred at homestead AFB something about fatigue in the wing roots, two crashes two fatalities. I don't recall if the F16s were grounded though.
-
the 15 that crashed seperated the cockpit area from the rest of the aircraft if I read it correctly. Let me see if I can find where I read that at.
And it was a 27 year old plane... how many people have a car that was made in 1980 that still runs?

Hah... Funny. BS, but funny.
The last set of F-16s that fell out of the sky... A batch of bad welds in the afterburners caused the AB section to literally fall off the plane. Since it's a single engine piece of..., losing one AB section means the plane fall down go boom.
They lost a few F-16 from this before they grounded the fleet and returned a few dozen megabucks worth of engine parts to the manufacturer.
The F-15 can lose one of pretty much anything and can usually still fly home.
The F-15... What, one inflight breakup in 30 years or so? Big whoopdee do.
Oh yea, the F-15E has demonstrated the ability to take 12+ G's with essentially no damage. One guy did this in my squadron (12ish G's during a bombing run pullup) and after thorough inspections, the plane flew again about a week later.
Even the F-15A and C are pretty durable. An early F-15 pulled about 11 G's and the only thing that flat-out broke was the fwd motor mount. The engines just klonked down to rest on the engine bay floor (the main mounts did not fail), and the plane flew home.

Search for F-16 wing cracks though, and you'll find that hundreds of F-16s were either retired early, or require major wing rebuilds due to wing cracks occuring far before the expected service life expired.
Also, the planes are not as durable as the F-15 so they get retired long before the F-15 service life expires.
Oh yea... Calling the F-15 not a "real fighter" demonstrates that you are amazingly ignorant about modern fighter aircraft. When it first flew, it had a gun and could out-maneuver any production fighter in the world. That makes it a fighter in pretty much anyone's book (except yours apparently).
This makes the second time you've trumpeted your ignorance about aviation in the last couple weeks... You might want to re-think how aggressively you post crap like this since you haven't shown that you have a shred of knowledge about this stuff.
Maybe you should take up gardening or something else where you can read a book or two and impress people with your knowledge.
:p

LOL careful eagl or you'll be Ignored also.:D

werent the navy f-16s retired because of fatigue?
-
I do see some articles by the USAF that say the F-16 has some cracks in its wings and hulls due to excessive use. And I did find some mention of faulty welds causing engine failure. But unlike the Canadian F-18s or the Navy's F-14s, the F-16s haven't been regulated for lower-g flight.
I didn't find any articles mentioning F-16 wings (or nose sections) breaking off in flight.
I think I read somewhere that only about 25% of F-16 losses were due to engine failure. Most crashes (of any plane) are caused by pilot error.

Im thinking your meaning the F-14 tomcats?
if so that is part of the reason.
It all boils down to money. The cost of keeping an F-14 serviced and able to do its job (which it did better than ANY other navy fighter) cost i think 4 times as much as keeping the newer F/A18's flying
The Tomcats were about the same age as the F-15's however due to the immense stresses put on the airframes they cost more to keep flying.
As to the F-16 debate yall might be thinking of a early manufacturing flaw in which the internal wiring wasnt properly secured and would chaff on the inside of the plane. This resulted in shorting out the hud and several flight instruments.
This issue resulted in some crashes one of wich was made into a movie due to the valiant efforts of the deceased pilots wife to FORCE the Air Force to admit the issue and Lockheed to fix all existing F-16's.
Just an FYI the plane had inverted at night in the clouds and the pilot "pulled" up to gain alt. Unfortunately he nosed down into the ground. The original AF report blamed pilot error which IIRC incensed all who knew him since he was reported to have been a very excellent pilot.

Eagl,
We broke an F15 at edwards a few years ago. Broke it good by over G in uncontrolled flight.
Of course it was made in 78 and took about 14 or 15gs. De-milling it was a PITA.
It's now a static display. I think the 15 is a great AC and can't understand this knee jerk but as allways "safety first"
PS you'd get sick to your stomach at how watered down BMT is getting. It sounds all warrior like in "airman's magazine" and such but it's really getting stupid. I'm not sure if I'm going to re-up after this tour.
We are creating a new banch of Airman that have to have somone do their work for them. Blame the NCO first should be our war cry.
-
Lots of guys i know arent reuping due to the southerly direction things are going.
personally I think its gonna end up biting us in da butt before to long.
Wonder how long till the conspiracy theorist decide its some kind master plan to either cripple us or force some more newer ucavs on us?

Well, your thorough objectiveness in the matter is understandable. ;)
Seriously speaking, I think both of these planes have shown to be capable world-class fighter aircraft in their own role if one looks at their service record and performance.
Although thankfully they haven't really had the ultimate baptism of fire against roughly as capable air force flying fighters these two would be competing against.
There always will be technical problems, fatigue and flaws in aircraft...always. In that sense if F-16 would have been too prone to problems I don't think they would still be flying them.
About the grounding...AFAIK it is a standard operating procedure in both civil and military aviation when an accident points to some alarming technical failure which' cause haven't yet been determined.
Does anyone know if there is any eyewitness/pilot reports published about this newest F-15 -accident?

Lol, I could post the most bogus stuff I could possibly think of, and my reputation still wouldn't be 1/10th of what yours is.

Like my reputation to you, much less anyone one a flight simulator BBS means a thing to me.
But watching you make an arse of yourself, repeatedly, its truly entertaining.
Shouldn't you be wooing us with your remarkable knowledge of, well, nothing?
Ah don't bother. I bet your diploma was signed by Sally Struthers.

For a person who spends as much time online as you do, I would imagine that you invest quite a bit emotionally in your online persona. For me, not so much. I can pretty easily recognize who on this bbs is genuine and who isn't. I don't mind agitating the goofballs.

I have a 36 foot 1947 ACF Brill Bus converted to a motorhome. Of course in the 1980's the Hall Scott engine was replaced with a 671 Detroit Diesel.
anybody with a 60+ year old vehicle?
Hell my bus is older than a B-52!

Your assumptions are, like your aircraft knowledge, wrong.
There are many, many others who invest vastly more time on here than I do.
I am certain they are anxious for more of your Madame Cleo/Horse Whisperer predictions of their emotions. Really.
We've all pretty much nailed you're a loser and still swinging.

A while back they flew one into Morristown, NJ on a "training" flight.
I figured the pilot must have given his CO some fine line of BS to authorize
a 3000 mile training flight to go to a family wedding :)
I believe they called it an F-16N, and it's home base was Miramar, Ca. It
was in the desert USSR paint scheme.

From the age when dinosaurs ruled the flightline:
We were at Tyndall AFB for 2 weeks doing some Dissimilar Aircraft Combat
Training in 1983 operating F4e Phantoms. Two interesting things happened
on that TDY. One, the middle weekend was the Tyndall open house where
we got to see the Thunderbirds operate the new F-16. The second was an
F4 that managed to over-Gee the aircraft positive and negative on the same
flight.
I saw the G meter carats at 10 positive and 8 negative in the aft cockpit after
the flight. The damage to the aircraft was extensive but was repaired.
Apparently both engines lost their mount bolts and were only retained by the
doors. An AIM-7 Sparrow launcher decided to depart the aircraft completely,
which is remarkable considering it was INSIDE the airframe! :)
Of course the F4 isn't really an aircraft, it's just an engine demonstrator for
General Electric, so maybe it doesn't matter if it bends like a banana inflight :D

I think my camp had a '58 bus. They chopped off the top of the back of the bus, installed heavy roll bars, and padded them.
I was there for a little party when it completely rolled the odometer over.
