Xenon Down at Sebring

When I saw this I called Scott Lewis. Roy (Bensen Days Airboss) is his next door neigbor and he was piloting the Xenon at Sebring.

So here is the skinny. Apparently the exhaust came loose on the turbo and the engine quit. Roy put it down on a sod farm. No damage to the aircraft or the pilot and passenger.

Hector and Juan left early so . . .no way to confirm with them.
Heron (hoping it´s just an emergency landing)
Yes!!!! it was!!! :D great!!!
 
Whew! That is a really strange thing to have happen...WHen I was racing 930 Turbo Porsche GT1, I caught my #1 competitor with his head under the rear hood of my car with a wratchet wrench in his hand as we were prepping the car for a race qualifier!!!!!!!!!!! No Kidding. My pit crew and I ran through the engine as best we could, and couldn't find anything amiss. When my turn came for my 3 laps, she started fine, ran fine, until I hit the boost adjust and turned the wick all the way up to get my 500 ponies pulling that 2000 pound monster down the main straight. The thing went bwAAAAAAAAAAAAAAAAAAAAggggggggghhhhhhhh !!!! and almost died. When I let off the gas, she came back to life and I ran fine again, until I cranked up the boost to 15 psi again on the next lap. Same prob, only this time she died down the front straight, and I coasted her off to the grass after turn 1. I popped the rear hood, and found the intercooler had come off of its stack! I pushed it back down over the O ring seals, jammed a fire extinguisher into engine compartment to hold the plumbing together and finished my 2nd and 3rd lap with no further problems. But the problem forced me to not be able to use the boost control and I started out dead last in the race, and came in 2nd to last overall. But that other idiot never even made it to the green flag! He had made a mistake with building his engine and it tore up his oil pump, ruining his $30,000 engine. What goes around comes around. Ooops, I think I just hijacked this very important thread. Sorry friends. I digress.
 
Joe has the story correct.

We gave a bunch of demo flights on Saturday after the fog lifted. On one late Saturday afternoon Roy landed about 1/2 mile from the airport on a giant sod farm. He did his usual great job of flying. At first the passenger who was on a demo flight thought Roy was just doing a demonstration of an emergency landing. He had a good story to tell later on.
The gyro was back in the booth Sunday though the crowds were pretty small because it was sooooo cold.
Next week will be spent trying to fly the 5 hours off the 6 new machines we have.

Good show Rob!
Sebring is always weather challenged, last time we could barely stand and walk against the wind took some exercise . . .
Are you plannig to stay in Florida? :D (please?)
What a great staff you guys are putting together!
thanks
Heron
(Greg M. do you still race) better go p.message.
 
I'm really glad no one was hurt and the aircraft is OK. Great job.
 
I "thought" about driving down to Sebring yesterday but,tooooooooooooo cold. It's even colder today.

Nice wam Florida, ay. It's sunny tho, not a cloud in the sky. Brrr.


Cheers :)
 
It is in the single digits here this morning.... With a expected high of nearly 38 degrees. Florida HAS to be better!

And Xenon down is a very misleading thread title. It had a engine out landing.... Not a big deal really.
 
You know how people can tend to overreact when they hear something went down.... It's okay though, this apparently was a non event. Hey Fish, whatcha flying these days?
 
Someone can correct me if I'm wrong but I'm almost certain it was a 912 RST Turbo. As far as I know I have the only 914 in the US and it wasn't mine.
 
It was a Xenon RST. David does have the only Xenon RT in the U.S.
 
Hi David,

I see that you have the same model that I am currently building. I got the last kit. I want to know your opinion on the nose wheel without any suspension and would like to modify that. I already made the plans but would like to know what you think ?
 
Jean-Pierre,

I have not flown "or seen" my Xenon yet. I plan to go to Florida in the next week or so to get checked out and transport it home. I will be glad to share my opinions after I've had an opportunity to fly it. All of us in the US purchased our Xenons "ready to fly". There are others in the country already flying their machines and may be better able to reposnd.
 
I don't see any need for suspension on the nose wheel.

Just out of curiosity, why do you think you may need suspension?

Hi Scott,

I heard that on landing on the main wheels and keeping the nose as long as possible in the air creates a sudden and hard drop on the nose wheel, which is not a problem with most gyros, but on the Xenon it shakes things a bit hard up to the point that the battery (which is near the nose wheel shaft) goes through the fiberglass and subsequent re-inforcement is required there.
Also gyros are fun to fly on bush runways and I would not like to limit my flying to tar. In my opinion (hence the question) a suspension would do well there.
 
Hello Jean-Pierre,

I understand the concern now. I haven't found that to be the case for me when landing. I'm guessing that the person who told you that is probably using a technique that leaves them in a very nose-high flare as the energy dissipates and the nose drops.

I have found that if you save a tiny bit of energy at the end, I can stop almost all of the forward motion and gently lower the nose to the ground. If you must do a short field landing and stop as quickly as possible, I could see someone touching down more firm on the nose wheel. Although I would say that even then it should not be hard enough to damage the composite floor where the battery is located.

I hope this helps.

Scott
 
Many thanks Scott, I'll try without the mod first. I am about 2 months away from 1st flight. The mod that I have in mind is a fairly quick retrofit but would put may be another kg or so.
I don't know if the latest xenons come with a permanent rotor brake system and control lock. I have changed the choke as I found unnecessary to have such a big lever on the console that is used only once per day. My choke is a small lever away from the console and I used that lever with cables to lock the controls in the formard position and keep the rotor brake on as well for taxiing.
