Flawed metal & failed communication: Breaking down the Air Force’s fatal Osprey crash

Documents reviewed by The Air Current reveal a persistent manufacturing problem with implications that extend beyond the V-22 Osprey and across military and civil aviation.

Highly recommended!

Yeah, that sounds like a training issue with Osprey crews... a Chip Light is a "land right effing NOW" item for helicopters!

Wut?

Exactly what it looks like

And the internet doesn't know about this, because it's an analog photo. The V-22 Osprey model with the ASC-890 Eireye radar, similar to the one on our Saab 340 AEWs.So what could have gone wrong here?

I mean, it's definitely a concept I've thought about before. But you can see some issues -- the radar beam translates back and up for landing, so the resulting aircraft is going to be extremely long. Maybe you could also slide it forward into the cabin, but you're going to need space in the cabin for operators.

As the comments note, vibration seems like it would be an issue, too. That's not a very rigid-looking structure and the last thing you want is the bean wobbling around. Seems like it would play hell with getting good resolution.

Yeah, that also. I mean, I assume it's within limits, because the beam isn't the only heavy part of the radar. Big chunk of signal processing stuff probably placed as far forward as possible.

I was assuming that the front A frame rolled like 270deg to stick the end of the beam into the cargo bay, then the aft A frame pushed the whole mess forwards.

Yeah, it just looks particularly awful.

Oh, that is possible. I didn't visualize it. but it makes sense.
 
Someone was going to hang, regardless.
 
oft badly made gears?

That will outright RUIN any aircraft design type.

Let allow a sub type of the, 66600 parts flyong in close formation, that are helicopters.

There is a some truth here but "Hunterbrook Media" looks extremely sketchy to me, being affiliated with "Hunterbrook Capitol" , which took a short position on Universal Stainless stock before their Media arm published this tweet and video, two months after the original Military.com story. That feels very much like an attempt to move the stock price to cover their short.

Here is the original article, BTW.

Flaw in Osprey Gears Was Known a Decade Prior to Deadly Japan Crash, Internal Report Shows

The revelations about the history of the gear problems come as family members from the Japan crash, as well as families of Marines who died in a 2022 V-22 Osprey training crash in California, are seeking legal representation.

Great idea!
The Royal Canadian Air Force needs a squadron or three of those Ospreys for the long-range CSAR role in the high Arctic.
They could get by with a simplified, non-folding version to reduce parts-count.

While a non-folding version is simpler, it's also then different than what the US uses and only on a couple dozen airframes. So all the development costs of the fold-less version get applied to those airframes alone. There's probably pins that get installed for maintenance that you could likely leave in place to permanently disable the fold.

I mean, the USAF Ospreys still have all the fold gear of the USN/USMC versions.


But yes, Ospreys, AW609s, or V280s for long range CSAR. That's literally what the Osprey was born to do.

Not much development needed - there would be no changes in the wing shape/structure, and so on - other than the removal of unneeded systems and parts related to swiveling the wing and installing bolts instead of the pins.

The main issue would be what the weight reduction does to center-of-mass etc - which shouldn't be too significant.

That's so they can transport them long distances quickly via C-17 & C-5.

And also stow them aboard ships, based on the lesson of Kitty Hawk acting as a floating SOF helicopter base during the initial invasion of Afghanistan.

Just permanently changing how the wing attaches to the fuselage.

Right now, the Osprey is basically built as two separate pieces, Wing and Fuselage. These then are held together through the fold pin.

You're not saving any serious weight until you get to redesigning the wing-to-fuselage joint into something that bolts the wing spars to the fuselage directly, and that's not going to be cheap to design.
 
About the only thing you could do is make a new wing with ~20 years more advanced composites and structures, with a V-280/FLRAA stationary nacelles. I suppose some of the hydraulic equipment necessary for folding could be removed for some weight saving, but likely less than we might think. But the redesign, build, and testing alone would make the cost unaffordable if there was not hundreds of aircraft being built/refitted.
Personaly I do not think the Canadian government would want to accept MV-22B that are redundant, due to the popular press.

I honestly hope that the US Coast Guard can grab the USAF extras, since they're already set up for nightmare weather SAR.

None of which actually needs to be done.

The Osprey works just fine with the current wing & wing-fuselage joint, the idea is to simply disable the wing rotation mechanism, replace the retractable locking pins with bolts, and remove the motor that rotates the wing.

The stated idea was to reduce maintenance needs, not to drastically reduce weight.
