| Subject: | Re: CJ6 gear collapse in Ontario |
To Quell any supposition and or controversial, argumentative postings from the
varia of subject matter experts we have here:
FXMI was completing its 4th night landing (of 5) for the pic's night rating re-currency.
FXMI departed CYRO and due to a low air condition, flew for approximately
20 minutes and then completed a touch and go at CYOW on a 10,000 foot runway.
Upon the touch and go, the pilot was heard to say on the frequency that
there was a strange noise emmanating from the gear and that he was returning
to CYRO.
Upon landing at CYRO, the PIC did not notice any strange noises coming from the
landing gear this time. The PIC usually used an ANR helmet for his flights,
but this flight had been conducted with a non-anr Pilot Headset. The Pic taxied
around the airport at low speed trying to "hear" the strange gear noises again.
The PIC then concluded the noise may have been an anomaly, due to the normal
noises the aircraft produced were usually "squelched" by the ANR.
The PIC, then taxied to position at CYRO and proceeded to complete another take
off and landing. Upon the normal landing and take off, the pilot exited the
runway, taxied back along the taxiways to the threshold and departed again. Although,
this time the pilot noticed a low air condition again (+/- 23atms).
The pilot did not, again, notice the strange sounds he had heard at CYOW. The
pilot during all landings checked for a 3 green condition, as well, when dark,
this pilot uses his flashlight to insure the poles are visible.
The aircraft landed normally, and slowed to a "fast taxi speed", the pilot initiated
right rudder to exit into the taxiway and the right gear leg folded. At
this point the pilot's main concern became shutting down the engine, shutting
off fuel and electrics. While this was being done the aircraft continued under
power, veered to the right whereupon it struck some runway lights. The first
runway light struck folded the nose gear. The second runway light was struck,
and finally the left gear leg collapsed. It is not clear if the geometry
of one gear leg holding everything up and plus the runway light strike, and subsequent
roll into the rough grass area caused the left gear to fold or not.
The aircraft came to rest in the grass area, and the pilot got out. No injuries,
and at first damage to the aircraft didn't look too serious.
This sequence of events was discribed to one of our Nanchang repair "Guru's" and
it was felt that the downlock actuator may have failed, and coupled with a low
air condition the other 2 gear legs may not have "locked" all the way. Again,
there were 3 green, and poles were visible. In hindsight, in the dark, with
only a flashlight to look at the poles, they may not have been "fully" up.
The aircraft was written off by the insurance company. The "straw for the camels
back" was a landing light nearly cut the rear spar on the center section in
half. Expensive fix.
I am the pilot, so I know what happened, there were witnesses, they saw what happened.
This was not a gear up landing.
Any other questions can be directed to me directly.

Elmar,,,,
and anyone else in Canada that wants hull insurance on Yaks, or CJ's.
The copa plan for hull insurance on our birds is useless. They won't even consider
a quotation. Marsh apparently likes to cherry pick all the nice birds.
Until Dec of this year we had no options, and very little competition. Now we
have the EAA plan. Become an EAA member and get awesome (much cheaper than COPA)
insurance. They will insure Changs, and Yaks.

Buongiorno to all.
A short introduction might help YAK/CJ fellows to understand a little more about
GT Propellers products and company mission.
We re in propellers business since 1969 with a family business conduction. 12 employees.
In 42 years of business over 30.000 propellers have been produced.
Fixed pitch ,constant speed ,ground adjustable.
We supply certified or experimental propellers,serial production or customized.
145 maintenance certification and sell of other propellers brands is in progress.
We got a special propellers production dedicated to vintage aircrafts.
Presently the biggest Vintage propellers we produce are : the 2.48,98 fixed pitch
for the Boeing Stearman and the 3.40,134constant speed,4/5 blades, for the
RR Merlin/Spitfire.( various Spitfire models )
The most complex prop we have in production is the controrotating prop for the
Bugatti racer replica.
We are partners in the adventure. www.bugatti100p.com
In house we work on wood ,composite and metal.
Most popular aircrafts/engines fly GT propellers.
We have worldwide sell and good business relationship with international propellers
colleagues as for example :
Sensenich in USA ,Helice Clerici in Argentina ,Ausprops in Australia as well as
many others.
Little GT subsidiary is based in Montreal managed by our partner Mr.Humberto Dramisino.Humberto@gt-propellers.com
During our career we had the pleasure to collaborate with various famous aircrafts
designer,as for example Stelio Frati, known for SF260,Falco,Picchio,ecc.
Ermanno Bazzocchi father of Aermacchi MB 339,still in service with Frecce Tricolori.
Prof. Pascale, founder of biggest european LSA aircrafts company call Tecnam.(
From 1995 over 3000 propellers have been produced for Tecnam)
The GT Yak adventure started 13 years ago when YAK Italia landed locally with the
early YAK52/50, imported from the ex east block.
( Not so far from Italy ! )
Some time later one of these pilot came to our door with his broken V-530 blades
completely damaged.
He said : can you help me? I do not know where to get new one !!
My boss said : NO WE CAN BUILT NEW ONE BUT NOT NOW !
After a long engineering and testing period,8 forced months included all weekends,
the GT YAK blades were ready to take off using the original metal ferrules.
These never seen before metal parts was kindly supplied us By Mark Jeffries @ YAK
UK. ( only sample 0001 and 0002 )
We were the first company to adopt a different blade design and 2.50,98 diameter
on V-530 hubs.( A couple of particular customers fly with 2.75,108 )
At that time we have tried to collaborate with Vperod people, but they were no
longer interested in propellers.
Some experience exchanged with various russian aerobatic competitors and in particular
meetings with the well know unlimited aerobatic champion Kairys Jurgis,
were fundamental to optimize the latest blade version.
( Very nice person to deal with )
The sample 0001 and 0002 had ground cooling problem immediately solved.
>From that time, all new blades are produced with new metal ferrules wich has been
improved internally.
The static blade retention pull test performed on 5 different samples, showed a
safety factor of 13/1.
Our choice of maintain the mixed wood blade construction was adopted for more reasons.
To preserve the proven affordability showed all these years by the original V-530
blades.Of course with an upgrade design .
GT design is different to V-530 in blade twist, airfoils, diameters, surface,
carbon skin, composite leading guard, scimitar tips design, metal ferrule.
Wood blades facilitate the european certification procedures.
Now under negotiation with EASA authority.
Another important point is that WE LOVE WOOD PROPELLERS construction !
We also produce all carbon blades but we do not have same feeling for these as
we have for wood.
The little scimitar tip design gives a modern looking but not too modern .
YAK 52 nose is not properly styled for modern appearance ,we think !
The GT M-14 blades safety, greater YAK performance all round, lower noise, fuel
saving hourly, about 15 liters/4 usg less,low maintenance costs, made us being
in compliance with the severe propeller selection requested by solo worldwide
yak 52 producer: Aerostar.
>From 2008 we supply an interesting M-14 blades numbers yearly dedicated to military
trainers exported in some asian airforces.
The contract was reconfirmed for 2011 some days ago.
Last summer the SN 00400 was produced and delivered to our Australian agent.
We really must say thanks to YAK blades experience because we have extended our
know-how on engineering and production of bigger propellers as for the Hurricane,Spittfire,P-40.YAK
3,ect.
The influence of YAK propellers system is clearly visible in our smaller constant
speed propellers too Rotax/Lycoming/Continental/autoconversions
Spinner.
We made a 480 /19 carbon spinner dedicated to V-530 hub fitted with
V-530 blades or GT.
Nice looking ,perfect cooling .
Different application of the back plate from russian spinner.
Our back plate require a spacer where we allodge it. ( no two halfs ).
A new oil tube longer is required.
The system is very solid and perfect to make a real dynamic balance.
New blades, good static balance, solid back plate spinner and an accurate dynamic
balance made the all prop package very very smooth.
( two samples are in service since last may )
This spinner engineering and rnd made the price little too high compared competitors,
so we have decided to stop the project for the moment.
Actually we are priced at 2.400,00 Euros,3.350,00 Usd.
At this price we found serious interestment only in military application.
All deposite advanced us have been returned or absorbed in new blades purchase.
During the summer we will decide if proceed or not.
AIBB report
Next days Ill be more precise on the AIBB report and the fancy prop failure invented
by a UK. LOM customer.

Buongiorno Alex,
So does all this text you wrote on the Yak-list mean that we will see a set of
those prop blades on a Yak-52 or a CJ-6 at either Sun-n-Fun or Oshkosh? I have
tried to communicate with "Humberto" via email numerous times but something got
lost in translation.
It's not the Talk I'm interested in, It's your prop blades on one of our airplanes
Walking the Talk, that will sell me on this prop. Quotes from your Engineering
department, filtered through Marketing may prove difficult to translate into
sales.

| Subject: | Re: GT YAK blades |
G'Day Craig,
I have found that whilst there is a slight com problem with Alex from GT props
in Italy, with a little bit of patience on both sides it seems to resolve itself
and all works out fine.
I am running a set of GT blades on our 18T and have sold some blades for Yaks here
in Australia.
This came about as I was looking for alternative blades to replace the V-530 blades.
Whilst there were no GT blades fitted to M14P in Australia, plenty of others, I
decided to buy a set as they are less than half the cost of a MT prop.
Turned out to be a good decision.
As I have previously mentioned, there is a notable performance increase and is
very noticeable during aerobatic manoeuvres.
In fact, I sold a set of Blades to replace the original V-530 blades to a bloke
that has built, and is flying, a Culp Special with M14P.
He reports less take off distance, better climb performance and cruise and far
less turbulence around the cockpit area that was created by the vortex of the
old blades.
It is as Richard so nicely explained, be it a set of GT or Whirlwind blades or
whatever, the fact that all these blades are of modern design incorporating modern
technology, there has to be a improved performance, but it would be nice
to see some actual test results.
I have a spare M14P engine and I had intentions of upgrading the supercharger with
a kit supplied by Richard Goode and also replacing the pistons with a set
from Monty Barrett.
This would have given a little over 400hp and I am totally happy running the blades
with that H.P.
Unfortunately I have had to temporarily put this project on the backburner.
These blades, as will the V-530, will also simply disintegrate in the event of
mishap.
It is a shame that there are difficulties with Humberto and in view of that, should
you be interested in a set of blades, I can perhaps circumnavigate sourcing
blades from your North American rep, Humberto, and organize to supply a set
of blades for M14P direct from factory thru my account.
Hope this helps,
Cheers from Downunder,
Chris.

Hi Mike,
thank you very much for your very informative
posting.
I am very sorry having heard what happened
to your beautiful aircraft, the pictures
on your website look devastating.
The reason I am looking into gear related
accidents is that I believe there are some
ways to make the undercarriage operation on
YAKs and CJs safer.
My personal nightmare is that I pull up
the gear accidentally while doing a
touch and go or cleaning up the the plane
at the hold line.
I am currently working on a squat-switch
solution for the CJ and I am waiting now
for better weather conditions to test it
in real time conditions. If you are interested
I will keep you posted.
Thanks again and good luck with your new
bird.
cheers
E.

Once again, My sympathies to my hardy RedStar brothers living up in the Frozen
North. You have suffered much this winter. As a show of solidarity, I worked in
my frigid hanger today dressed in summer shorts. It was tough enduring the bone-chilling
61 degree temps inside the hanger during the morning.
This was a self-sacrifice that was it's own reward when temps went over 75 degrees
but heh, Spring is on the way. I feel your cold :>)
I challenge my California brethren to demonstrate the same sort of solidarity....

G'Day Eric,
Glad to hear that.
Are you running a set of GT Blades? And if so, how do you find them?
I would be interested to know the price of the Whirlwind blades.
Cheers,
