Do we qualify as 'accident investigators'? One day the investigation may let us know. Yes is good motor kept going etc.

Nope, not at all.

I'm just curious how that which could not faze the F135 motor (assuming birdie went down the intake) could cause the undercarriage to become too scared to want to go to work? Hopefully after the real accident investigators complete their work, we will read about it.

Bird damage? Some combination of creature and velocity sufficient to penetrate structure and damage components critical to the function of the ldg gear system(s). F=ma.

I'm going to have a MOAN. But First.... probably we will see something about this birdstrike.... SADLY we hear nothing about the Tanker/F-35B ARF collision and loss of that aircraft for example. The DoN is very tight-lipped about safety issues these days. We had to hear about other F-35B losses because they affected other users - what's up with the DoN?

If you have a pain, take a pill; personally, I prefer a good Kentucky bourbon.

There are formal processes through which these things are resolved; you know that. No one here is speculating; some (eg steve) only trying to understand how something commented upon by official sources could be causal…because they’ve never flown mil aircraft and don’t understand from experience how some of these things might occur.

Yeah but the USN NavAv culture seems to be closed these days - compared to yesteryear and even beyond (to my time reading ancient but current then USN safety publications). APPROACH magazine is a joke never to be found anymore.

[size=85]14 Jan 2022 YONHAP[/size][/quote]

(I can't read Korean, so I yomped over to some non-Korean sources.)

https://japanese.joins.com/JArticle/286753

2022/01/15:

On 2022/01/04, the ROKAF Major was minding his own buiness in his F-35A when he felt/heard a sudden bang.
Except control stick and engine, his aviation electrical systems failed, decided to emergency land at Seo San AB, and couldn't lower his landing gear.

(Pilot's family name is one of: Bae, Bai, Bay, Pae, Pai, Pay.)

During accident investigation, right engine intake had bird strike evidence.

(BTW, I miss the good old days when the flight engineer could crawl into the landing gear bay, and manually crank down the landing gear.)

Not even its serial number.)

More 'ambulance chasers' per capita these days. Aviation is a gold mine.

Newer generation's solution for something not going their way is a lawsuit. External legal pressure probably tends to stifle or impede military transparency to some extent.

sidebar: I believe there are lawsuits pending in both the T-38 formation landing accident at Vance and the T-6B loss of control accident in Florida.

Thanks for the link. I should have been more clear about RIGHT / LEFT. This is the quote from previous page about the
Bird strike confirmed in connection with F-35A fighter's belly landing: Air Force 14 Jan 2022 YONHAP
"SEOUL, Jan. 14 (Yonhap) -- South Korea's F-35A fighter jet made an emergency belly landing following a bird strike on its left engine intake earlier this month..." whereas your post said "RIGHT INTAKE". quote: "...During accident investigation, right engine intake had bird strike evidence...." witchizit? 8)

(Off-Topic Alert)

FYI, decades ago, even in Japan and Taiwan, after F-86s and F-104s crashed, and their pilots' bought the farm, the pilots' families also sued JASDF or ROCAF.

In recent years, details of some such classic jet fighter accidents became available in public domain Internet, when courts on-line published the verdicts.

For example, I didn't know F-86D electronic fuel controller, its main amplifier and afterburner amplifier circuits had 40+ vacuum tubes.

FWIW, I fed this article into Google Translate.
It's dated 2022/01/05, so it doesn't mention left or right intake.

https://www-yna-co-kr.translate.goog/vi ... r_pto=wapp

OTOH, it has more accident details, and apparently the pilot's ability was sierra hotel.

"The F-35A is a state-of-the-art fighter whose information from all the sensors onboard is fused into one.
As an avionics system malfunction occurred, virtually all electronic system equipment, including the landing gear, did not work.

"According to an Air Force official, it was difficult for the pilot to even recognize the location of the fighter because the navigation system, which is the 'navigation' of an actual fighter, did not work."

I'll guess details will become better known all in good time. No doubting the skill of the pilot :applause: :crazypilot: I'll assume he was at low level (hitting birds) so VFR. He would have known where he was without any navaids but then again he diverted to the emergency field so that would require some local knowledge which he had in spades one would hope? 8) :inlove: :whistle: :mrgreen:

It does beg the question if "virtually all electronic equipment" includes his HMD and the entire panoramic display went tango uniform.
Take an F-16, stir in A-7, dollop of F-117, gob of F-22, dash of F/A-18, sprinkle with AV-8B, stir well + bake. Whaddya get? F-35.
