Frankenotter Groundlooped!

Recommended Posts

This quote appeared in a weekly DZ newsletter: "So... there I was, beautiful Saturday, getting all geared up for my fourth jump, and someone runs into the hangar yelling "HOLY S**T!!!!!
Frankenotter just groud looped!!!" Picture below... The landing gear snapped on the left side on landing. All is fine, though.
It should be repaired and flying back to CSS today. More importantly, noone got hurt. Mario is an AWESOME pilot for saving it from more extensive
damage....

Anyway, thought I would pass this along since I hadn't seen it anywhere.

That was my quote, and I posted it on here on monday or something... anyhow, here's the pic if you missed it... Damage was minimal, thanks to Mario the pilot.

Why did the landing gear come off in the first place? You know, DeHavilland built the Otter like a tank. The landing gear doesn't "just fall off" randomly. "Shit" does NOT happen all the time.

Anyone care to explain this?

well, driver, i'm no expert, nor am I a pilot, but what the machanic told me in passing is that there was a crack under a weld that "couldn't have been seen". When I went to check it out, it didn't look like it just "decided" to snap off... there looked like the was rust run-off near the break...

That's about all I know. Like I said, I'm no expert...I attached a pic of the gear, this may illuminate someone with a little more knowledge...

Like I said, I'm NO expert!!!!! And the last thing I want is something like this to ruin otter boogies in Canada!

We rarely get the chance to jump an otter here, and now people down south are getting wiser and sending them up during their "slow" season. I hope this won't stop because of what happened!

Dammitt....BLAME CANADA!!! They broke the Frankenotter!!! Those bastards!!!!



Don't blame Canada. Painting it is what cursed it. They should've just left it alone to be ugly. Maybe they used Canadian paint....hmm

Right....it's all because of a big curse. Has nothing to do with inspections. Right.

Chris is correct. The metal skin and welded steel on any airplane will expand and contract to a degree as an airplane ascends and descends. Weld points and attachment points are where most failures will occur, because that is were fatigue from stresses will push the metal to seperate.

An inspection should have caught this. It's not "random" circumstance.

Speaking of fatigue... I wonder if the C-130 crash a couple months ago when the wings folded up could have been prevented beforehand by an inspection.

The only thing you can blame Canada for is Celine Dion.



OH GOD!!! please rid us of the friggin bitch!!!! She's Satan's daughter, I'm sure of it! Quebec (non DZ)trailer trash with a voice and a big ego.

Fuck, one person makes it big from Canada, and people start lobbying for buidlings and streets named after them! it's pathetic! [/rant]

Good lord people. It was a joke. I'm not stupid enough to beleive it was cursed from the paint job. I was feeding off of Clay's joke blaming Canada.

As it happens, I am an expert (Ph.D. in metallurgy/materials engineering, extensive experience in failure analysis). Unfortunately your picture is not clear enough to draw a conclusion. If you could get a close-up of the fracture surface and the "rust" stains, it might be possible to figure out why it happened.

BTW - fatigue cracks can be invisible to the naked eye up until the point that the component breaks, don't expect a 100 hour or annual necessarily to pick them up. That is why ultrasound/X-ray/eddy current/dye-penetrant tests were developed.
