>The incident took place at around noon and involved an F-35A aircraft from the 61st Fighter Squadron located at Luke Air Force Base, the service said in a statement. No serious injuries seem to have been sustained by the pilot or nearby crew.
>"The pilot had to egress the aircraft during engine start due to a fire from the aft section of the aircraft," Air Force spokesman Capt. Mark Graff said in an email. "The fire was extinguished quickly.

Damage is unknown, but should be relatively minor (there's still a high probability it'll be a Class A mishap though).

Cause is unknown, but it could be a hot start (during the early stages of engine start-up, fuel flow is excessive and when the fuel ignites, temperatures rapidly rise due to the lack of bypass airflow from the engine fan). The FADEC should prevent that though. Overall there's quite a few things that could have gone wrong. F-35s have flown roughly 70,000 flight hours to date; there's a first time for everything, but I think at this stage there's a reasonable chance that human error could have caused the issue, similar to the coolant line insulation issue (which is unlikely to be related to this).

>>
>>31436370
Excessive fuel flow should make it run cooler, though. You're only going to burn as much fuel as you have air available, and the rest evaporates and takes heat with it.
>>
>>31436809
The problem however is that there's plenty more air than fuel (hence why afterburners work); bypass air is critical in keeping the turbine and combustion chamber at acceptable temperatures. If it was a hot start it would have also happened after the fan / compressor had already started moving as well (just not fast enough), so it's not as if the engine would have just filled up with carbon monoxide, etc and self-extinguished.

Really it would be better if unrealistic expectations weren't demanded then correspondingly set at the start. We should recognize we are doing things that have neva been done befo and accept, and communicate, that there will be failures along the way.
>>
>>31437442
Agreed; one thing of potential concern is that this could be a nozzle fueldraulic issue - to preheat the fuel (and make it burn more efficiently), reduce IR signature and eliminate another hydraulic system, fuel is used to actuate the engine exhaust nozzle. That system has been working fine since 2006, but it's possible that either a maintenance error or just a random failure of some component could have leaked fuel at the nozzle.

i swear, only in the F-35 is a hot start national news.

they're unusual, but they're not unexpected. there will probably be some note or warning in a checklist once they figure out that if you have these combination of issues, you can get a tailpipe fire.
>>
I had a hot start/engine fire in a super hornet, and those have probably had millions of starts. The FADEC should have stopped it, but it didn't. I was in the heat of mid day as well as the exhaust of everyone in front of me because I was right in front of the tower. During start the APU over heated and shut down, but fuel had already been introduced. The rpm stopped increasing and I saw the EGT increase rapidly. I was luckily paying pretty close attention, and shut it down. But had to get out to allow an inspection.

The point is: even mature aircraft can have issues like this. We just don't make the news when it happens.

F-35's have flown about 70,000 flight hours so far, with 20,000 having been achieved just since February this year; there's also about 200 F-35s now flying (or grounded heu heu)

To give a comparison, the YF-16, the rough equivalent of the X-35, flew in 1974. Then in 1976 the equivalent of the F-35A, AA-1 (the first test F-35) flew. Then in December 1978 the first production F-16 flew and the F-16 entered service.

From 1976 to 1986, 120 F-16s had crashed - most had been from pilot error or unknown reasons, but at least 32 were attributable to design-related issues (engine failures, EPU failures, fuel pump failures, fly-by-wire sensor failures, etc).
>>
>>31438811
>Hmmm, F-35 hit 50,000 fleet hours in February, which puts A at 2.00 (1 incident), unknown B, Fatal rate of 0.00, and with first flight close enough to 9 years prior, and ~5,555 hours a year, though that'll change as production and entry to service picks up.
Nice get. Comparing this to:
>F-15 at 50,000 flight hours - 7 total Class As, rate of 14
>F-16 at 50,000 - 14 total Class As, rate of 28
>F-22 at 50,000 - 4 Class As, rate of 8
>A-10 at 50,000 - 7 Class As, rate of 14

The F-35 dev program, testing protocols and LRIP plan starts looking really, really good.

We don't. The F-35 had a record at 50,000 fleet flight hours 14 times better than the F-15 at the same point, 7 times better than the F-16 at the same point, 4 times better than the F-22, and 7 times better than the A-10.

See >>31438898

I'd recompute for 70,000 hours, but it'd still be by far the safest modern fighter program in terms of Class A mishap rates in history, and you won't recognize facts anyway.

So it took 10 years of fully operational service for a mass-produced aircraft to crash 32 times because of the design issues. Call me back when F-35 will be mass-produced and in fully operational service for at least 10 years and we'll see its record. I'm sure it will be less than three dozens aircraft lost and I'm sure it will be far from zero.

Once more for the fucking potato, see >>31438898 for a complete comparison between the F-35 Class A mishaps up to 50,000 fleet flight hours and the F-16, F-15, A-10 and F-22 at the same exact points in their service lives.

That was 10 years from the first production test aircraft flying, not from IOC or FOC (speaking of which, the F-16 at FOC was 100x less capable than an F-35 in IOC is today). The first production aka LRIP F-35 flew 10 years ago.
>>
>>31440761
Most reasonable and well-read anons realize that the F-35 project has been remarkable quiet as far as Class-A mishaps are concerned.

How many of these F-16's 50000 flight hours were during mass production in fully operational service? How many of these F-35's 50000 flight hours were during mass production in fully operational service?
>tell me about how the F-35 is falling out of the sky
Tell me about how it is "still basically in the prototyping stages of its life". Or "fully operational". By now it seems like F-35's operational status is changing in regards of the benefits it provides for a fatnik arguing at 4chan.
>>
>>31440800
I think a better question is what impact there is to a jet being fully operational, especially when these losses being counted aren't combat losses?

"still basically in the prototyping stages of its life" isn't the most accurate way to put it, but it's not technically wrong; a prototype is simply something that hasn't been fully developed yet and the F-35 doesn't finish development until around November 2017.

At the same time, a prototype can still see IOC and/or still be used in combat; just look at the XM-25 airburst grenade launcher for example; it was used in combat in Afghanistan in 2010, yet it doesn't officially enter service until next year.

Overall, the F-35 is in service, has reached IOC in two services, is being operationally deployed next year and will likely either see combat later next year or in early 2018, assuming that Syria doesn't suddenly see peace in the next 12-18 months. There are also around 195 F-35s currently flying (technically ~180 if you factor in the 15 that are grounded). The F-35 isn't mature yet (it officially become mature at 200,000 flight hours; right now we're at 70,000 and rising exponentially with the rate right now being roughly 30,000 flight hours a year), so it won't officially be mature until probably some point in 2018.
>>

Why does it keep catching on fire though?
>>
>>31440891
There's quite a difference between the service of a prototype in testing and a fully operational aircraft in mass production. Namely, the more aircraft you produce and the more you operate it the higher is the probability of issues emerging.
The point about it being or not being it its prototype stage is that regardless of how it is in reality fatniks will claim whatever suites them of the sake of supporting their argument. Another day one told me Sukhoi is "struggling to meet deadlines with T-50". When reminded that it has only been 6 years since its first flight, while it took 15 to adopt F-22 in service and with F-35 it is by now 16 and still going he resorted to claiming that "F-35 is fully operational bruh". But as soon as an accident happens a fatnik claims it "still basically in the prototyping stages of its life".
>>
>>31440800
>How many of these F-16's 50000 flight hours were during mass production in fully operational service?
Tell me how this is relevant in Class-A mishap rates. Flight hours are flight hours, and while some testing regimens are markedly low stress, so are standard patrol flights. Not to mention the fact that more F-35s currently being in the air than the total number of F-22s in existence more than makes the argument for this being statistically relevant data. Cycles and hours are what they are. Someone from within the aviation field would recognize this.

>Tell me about how it is "still basically in the prototyping stages of its life".
I never said any such thing, but if we are on the topic, one can argue very successfully that either the F-35A and B are more operationally capable than the F-16, F-15 or F-14 were 5 years into their operational life or they were still prototyping 5 years after service introduction. Both of which are true, by the way, as militaary airframe development and upgrading never really ceases and the only line between "development" and "service" is a nebulous area where basic capability is declared. Which it has been for two variants.

>By now it seems like F-35's operational status is changing in regards of the benefits it provides for a fatnik arguing at 4chan.
See above. Tell me what front line aircraft is ever completely development frozen, and I'll show you an aircraft which is about to be completely retired.
>>
>>31441109
>Namely, the more aircraft you produce and the more you operate it the higher is the probability of issues emerging.
Sure, but you have to also factor in how programs a run - the F-35's test program is far, far more comprehensive and lengthy than the F-16's; partly because of the complexity / more capabilities of the F-35 and partly to reduce the chances of having F-16-like loss rates. Ultimately, however you compare them the F-35 has a considerably safer program of record. For example, assuming every F-16 delivered prior to a year flew 300 hours and the jets delivered in that year flew 150 hours, we'd be roughly up to something like Q2 1981 in terms of flight hours, at which point there had been around 7-9 crashes attributable to design issues.
>>
>>31441109
>Namely, the more aircraft you produce and the more you operate it the higher is the probability of issues emerging.
Which is the entire fucking point of extending the testing and evaluation period with lower production tranches with the LRIP process. By doing so we uncover and address the issues that plagued the F-14, F-15, F-16, F-111, F-22, etc. before the aircraft are fully mass produced and three years into service and require massive refit programs instead of proactive solutions on the front end.

>The point about it being or not being it its prototype stage is that regardless of how it is in reality fatniks will claim whatever suites them of the sake of supporting their argument.
Are we now implying that EVERYONE doesn't do the same? Are we now forgetting that some of the most spectacular examples of doublethink arise from Russian justifications for Ukraine and actions in Syria?

Glass houses. Stones. Throwing. Etc.

>Another day one told me Sukhoi is "struggling to meet deadlines with T-50".
This is manifest and provable fact, just as the F-35 at times has been pressed to meet the program schedule.

>When reminded that it has only been 6 years since its first flight, while it took 15 to adopt F-22 in service and with F-35 it is by now 16 and still going he resorted to claiming that "F-35 is fully operational bruh".
Going by published program dates for the PAK-FA, plus early budgets, it is not completely on the rails. Just ask the Indians. Whataboutism does not change this fact.

>But as soon as an accident happens a fatnik claims it "still basically in the prototyping stages of its life".
Why are you so hung up on this perceived injustice? The aircraft is not yet finished with development. On the otherhand, the aircraft also displays and is certified significant combat capability. If you're trying to imply that it is an absolute black and white in this issue, you do little but show your own ignorance.

No, it's ok. Don't bother with an actual argument or reference to real world facts. Memes and le punning brown trollface will totally salvage a completely bankrupt intellectual position on the relevant matters.

There are not 18 F-16 crashes per year. 2016 has had 2. Out of the roughly 4,000 currently operating. Jesus, it's like anyone can get on the internet and just say whatever they want.

Not who you were replying to but globally, there are usually quite a few serious F-16 incidents a year, even if this year seems not too bad.

egress is the standard term for it in the Air Force. we all know our emergency ground egress procedures, and the command of execution of it is "Egress, Egress, Egress". on the third one, you get the fuck out of the jet.

tl;dr shut the fuck up.

The F-35 will eventually turn out fine, but you have to admit this program was mismanaged to an outrageous degree. Making a stealthy F-16 replacement should not have taken this long. Let's remember that the original X-35 demonstrator flew in 2000, so 16 years later they still are having significant issues.

Can we let this stupid meme die already? The only mismanagement was the stupid planning before the F-35 design was even finalized that have it that timeframe

Do you truly believe that it is acceptable to wait so long for a new fighter jet? Come on man, all the services are being hurt by this: they're losing falcons, hornets, and harriers because the air-frames have reached the end of their lives but they have to keep flying them because the replacement isn't ready yet! And many are saying that the F-35 won't be truly ready until after 2020!
>>
>>31456117
This might come as a shock to you, but the F-35's development time has been comperable to the Eurofighter and Rafale.

And if an airframe has reached the end of its life, it does not fly at all.
>>
>>31456117
>Do you truly believe that it is acceptable to wait so long for a new fighter jet?
Typhoon, Rafale, etc. all took just as long.

It takes a long fucking time to get a modern fighter into service, anon. It's not like it was back in Gen 3, even in Gen 4 they didn't get those completely ironed out with full designed capabilities until well into their service lives. For instance:

>F-14 first flew 1970, didn't finally overcome the compressor stall issues and achieve designed kinematics until the GE F110-GE-400 with the F-14B along with the essential RHAW systems, 1987.
17 years to program defined full capability.
>F-15 first flew 1972, didn't finally overcome the engine issues with concurrent high loss rates until almost 5 years after it was introduced in 1976 and didn't fulfill what would be considered full capability for the F-35 program until the F-15C was introduced in 1979.
7 years to program defined full capability.
>F-16 first flew 1974, didn't fix the engine issues for several years after introduction in 1978, and the horizontal stabilator issue wasn't addressed until Block 15 in late 1981. It didn't achieve full capability all-weather status until Block 25 in 1986, when it also finally upgraded the engines.
12 years to program defined full capability.
>F-111 first flew 1964, didn't come close to achieving program designed goals until the F-111F in 1970, and even then was deficient in some requirements.
6 years to program defined fullish capability.

For reference, the F-35 is so much more complex in numbers of systems per volume, software complexity per aircraft and overall technological risk that comparing it to the Block 0 F-16 is like putting a 1967 Mustang GT next to a current year Porsche GT3 RS. They're both sweet rides, but not even in the same ballpark really.

With modern CAD software and engineering tools the amount of time needed to develop a new aircraft should be shrinking, not growing.

>With modern CAD software and engineering tools the amount of time needed to develop a new aircraft should be shrinking, not growing.
Not when number of systems, systems integration requirements and systems complexity are all growing exponentially it shouldn't. Also, physical design of the airframe is by far the simplest and fastest completed part of the process. The time sinks are the software writing, electronics hardware design and integration, material science across the airframe, VLO features and engine and production flow optimization.
>>
>>31456960

Then at some point the question must be asked if these new features are important to justify the increased complexity. Otherwise you'll end up with a smaller and smaller air force as time goes on.

>if these new features are important to justify the increased complexity. Otherwise you'll end up with a smaller and smaller air force as time goes on.
Considering the capabilities they bring, the demonstrated dominance of the F-22 and the recent displays of A2A and SEAD dominance displayed by the F-35, I'd say that question more than answers itself.

Read the following for an in-depth and well written analysis of low-cost high numbers procurement philosophy VS high-tech procurement philosophy, as it was surrounding the various controversies with the introduction of the Gen 4 aircraft:
http://etd.auburn.edu/bitstream/handle/10415/595/MICHEL_III_55.pdf

Furthermore, the USAF alone is procuring 1,700+ of the F-35s. That means that in F-35s alone the USAF will be larger than any other entire air force in the world. Hardly smaller numbers compared to others. Finally, after a certain point the costs themselves become very close to equivalent between 4+++ gen and 5th gen fighters. See: Eurofighter, Rafale, Gripen NG/E vs current and projected F-35 prices.

TLDR: both the F-22 and F-35 have shown themselves to be massive force multipliers, so the answer to the question is an emphatic yes, it makes sense up to a point.
