Chuck, in away has done us all a big favor
identifying

this

mode

of engine failure. I think we should all send him a
check for what ever we can afford to help him pay of

his

engine over haul. He is going to need a

new rotor

housing and a new rotor for sure. Probably at least
one new

end

housing.

What is your mailing address Chuck?

    It's going to take time and money to examine damage
and come up with a fix would like to donate too.
    Let us help you (help us) the rotary engine is
evolving,

stuff happens in the process and this seems to be the
forum to

find the answers.  thanks for all the effort everyone, doc

maglaughlin

 Thanks for the offers, but I am in this with eyes wide
open, if

anyone

finds my experience valuable, just consider it a trade for
all

the

tips

and valuable knowledge I get from everyone on this list.

Here are a couple of photos of the damage. The center
housing was untouched, the end housing had a small amount of

metal displaced at

the

edge of the inlet port, may be repairable by enlarging the
ports. The rotor and rotor housing are history. It was a new

rotor housing, rotor and end housing was used parts when I
built

this motor. I had about 80 hours on this motor, with Paul's
TES oil O rings looking like new,

will

likely reuse them.

Chuck have you notified Pineapple Racing about this failure? The

least they could do is help you out with the rebuild.

BTW it far, far better for us to contribute to your engine
rebuilding cost than to the Chuck Dunlap Memorial fund :)

Chuck, let me know if you're in need of any hard parts.  I may
have some here that you can use for your rebuild or can find them
easily.

Also, great news on the TES oil control ring o-rings; I've been
waiting for a practical, positive review to come

out.

They
should be fully re-usable.

Do you have a picture of the end plate that got nicked near the
intake

port? I'll tell you if it can be removed from porting work or not.

7/20/03 I emailed Rob Golden at Pineapple Racing a description of
the failure, no response yet. I have already repaired the end
housing damage, it look OK to reuse. The only photo I took was the
one previously uploaded, endhousing_rotor_damage.jpg it shows the
damage pretty well. I have ordered new rotor housing and seals from
Mazdatrix, should arrive next week. I have always had a spare motor,

I can use a rotor from that but I

would

like to come up with another rotor to keep the spare motor parts

intact.

Brian, can you find a 86 NT rotor for me?
Thanks

Chuck Dunlap

Some of us are profoundly upset by your engine failure and near death
experience. It would make us feel better if you would allow us to help

you out with the rebuild.

Paul Lamar

"Near death experience"? This story is getting better and better :-)
It seems to me that I come that close to death every morning as I
drive to work. Monetary donations will not get me back in the air any
faster, It would make me feel better if people would donate to the
Everett Hatch Memorial fund instead.

Chuck Dunlap

Too late. Check is in the mail. I already donated to the Everett Hatch
Memorial fund as well :)

There is something that is not clear Chuck. Was that motor home coming
towards you? Do you think there was a slight downdraft behind the motor
home causing you to lose a bit more altitude as you just passed over it?
How much did you clear the motor home by?

Paul Lamar

Yes it was a truck pulling a large travel trailer coming toward me. I
did not think about a downdraft, that is possible I suppose. My
instructor always said I invented downdrafts as an excuse for some of my
landings. I must have cleared him by at least 6 feet, probably more. He
said he thought I was buzzing him, playing around. The prop was still
spinning.
