A gyrocopter crashed at the Nashua NH airport. Looks like he was taking off from the runway then ended up crashed in the grass. No or minor injuries. I was there about a 1/2 hour before this, the winds were funky. Nothing too bad they were advertising about 8 or 9 knots when I was there, but it was a little gusty and funky, you needed to be paying attention. I was in an SR-22.

I'm the pilot. Remember taxiing to the run up area then getting permission to take off, then aligning at the runway threshold. Then, nothing until awaking in the emergency room. They said I went 1000m down the middle, approached 100mph veered onto the grass, then when i hit a slight ramp at taxiway C , that threw me into the air and then tumbled about 200m more. Broke t5and c9 and a small bone in my foot. The plane can get into ground effect at 30mph. Do not know how it stayed aligned and on the ground until I hit the bump.
 
Thank you for sharing your experience Jim D, your accident was a real puzzlement to me.

Good gyroplane, good instruction and good weather.

Wow! That is a pretty wild first ever post.
That's quite a ride and quite a story. Wishing you a complete and speedy recovery Jim.
 
Get better soon. Sorry this had to happen to you.

Probably the worst thing is not remembering exactly what went wrong?
 
I had to be doing something to stay in the middle and be going nearly 100mph. The torque on that plane, about 1000# with a full tank of fuel and me in it would have twisted it left way before it went left slowly. I don't know how well it can hold itself straight with the rudder and rotor on smooth asphalt at 100mph while rolling, normally you'd have been in the air way beforehand. First full day of rehab. Not really looking forward to tomorrow, either.

if things happened a little earlier or later, the end result could have been a lot different. Could have shut down and called for help, or flying around for the next 4-hours or so until it ran out. A lady in Italy around 2-years ago, got hers up over 28k, and this one has over 37 more hp at cruise. Don't know how long it would have lasted at max, where it makes even more for takeoff (914:115hp; 915:141hp).
 
Jim, so sorry to hear of your incident and glad to hear you are OK, although a bit broken. Wishing you a speedy and full recovery.
 
Glad to hear you are “ok”. Sounds like you’ll have some time to be tapping away on PoA. Looking forward to your contribution.

Jim, I was at Nashua in an SR-22 about an hour before you crashed. The wind was funky that day, hard to describe, but it was kind of swirling from about 800 feet down to the runway, not a big wind (maybe 8 or 9 knots) but little gusts in different directions is what I remember. Nothing to really note in the Cirrus, but enough that I noticed it.

Glad you survived, I hope your recovery is going well.
 
wishing you a very speedy recovery for sure!
I've been fascinated by the gyros for a while now. Surprising we don't see more of them around
 
A little update...doctors said I had an embolic stroke that hit both sides of my brain! In reviewing the ATC radio traffic, to me, anyway, the communication I had after getting permission to takeoff sounded a bit 'off', so I think it was starting then. FWIW, I remember lining up at the threshold and starting to pre-rotate the rotor, then nothing until I woke up in the ER maybe 4-5 hours later. From data I was able to pull, the plane hit 115mph (100Kt) before it drifted off the runway and the rotor tach showed enough speed to get off the ground. It appeared that I was just holding the stick full forward, which is why it didn't leave the ground until it hit the bump crossing taxiway C from the grass. Going to get a look at the thing tomorrow, and, hopefully, at least some of the electronics are salvageable. Will need to get a Rotax shop to download the info from the engine controller. Broke all four propellers off (carbon fiber ones) about 10" from the hub. Don't know when the engine stopped or if it over-revved. Ground adjustable propellers were adjusted for max on a hot day in northern Italy...in the cold and low density altitude, it had been maxing out at around 5300 which, with the 915is is plenty to get the thing climbing at close to 2000'/minute. Probably at least the gearbox is going to need major work and the engine may need a major overhaul...only about 10-hours on it. The plane is essentially trashed, otherwise. The airport manager said that when they got permission to move it to storage, the carbon fiber fuselage (the aeronautical steel frame is the only thing structural), it pretty much started to fall apart and his arms were covered in carbon fiber dust. They tried to lift it from the side, and essentially, the engine stayed put (the frame was bent and the boom sheared off)...had to go from the rear where they could get the engine to help lift it. I think that the fuselage acted like a big airbag as it crushed like the shell of a hard-boiled egg, absorbing lots of energy, which is probably one reason I'm still here. If it were something like a Cavalon, that has a much more pointed nose, that would have probably dug in and the g-forces much higher. The CF on the Magni is essentially just there to move the air around you and is flexible if you push on it, and only stiff around the doorframe and windshield because of the creases. FWIW, this airframe is certified most places in the world, but not (currently) in the USA.

Doctors say the probability of another stroke in 5-years, is around 24%. No prior warning signs for this one. If I fly again, it will be with a qualified safety pilot, which, on a gyroplane, is not that easy! It's not worth it to buy another as some of the fun is going places you can't drive to and taking a friend along for the ride.
 
Thank you for the update, Jim D. I'm glad you are OK and have the explanation for "what went wrong;" I'm also sad to hear that your shirttails have been tethered.
Here's hoping you find a good gyro friend! (Perhaps there is one ripe for the making at your airport ... :) )
 
Glad you are recovering and have some answers...hope you do get back to where your back in the air. Flying a gyrocopter is a whole different level of passion in my opinion....or maybe crazy...but I salute you for that.
 
Did some salvage work on the plane today and removed most of the electronics. The two Dynon HDX display screens have some very minor pitting, but otherwise, look okay. The radio, ADS-B and intercom look good. Can't get to the ADHRS box until I start cutting it up as it was forward near where the nose wheel was, and that area is all crushed and collapsed. I'm going to cobble up a connection to one of the displays and see if it powers up properly, and then see what is in its data log. Going to call a Rotax dealer next week to see if they can pull data out of the engine controller. Got that out. I was concerned that the impact might have damaged the oil and coolant radiators, but those are intact. Surprisingly, it took off all of the transponder and ADS-B in/out antennae, but the VHF one looks virgin and it stuck down more than the others!
