| Subject: | Weak 701 Nose Gear? |
Recently a learned about a new (~30 flight hours) 701 that had its nose gear
collapse on landing, causing considerable damage and was able to obtain two
pictures (see attached). The gear tube buckled and bent back just above the
lower bearing, which bent the lower bearing and firewall. The wheel bent
against the fus and deformed the lower structure behind the gear. The
radiator was pushed up into the exhaust and holed, and the bottom cowling
was damaged. The prop, and possibly the engine were also casualties of this
collapse. The wheel axle was bent up with the bolts holding the axle to the
fork still in place. The fork was bent and the tire pushed upward into the
fork so that the tire tread was cut by a bolt on the inside of the fork. The
upper gear tube and upper bearing did not appear to be affected.
I was able to find out that the plane was not overweight and the pilot and
passenger were not injured. The pilot said the plane was built to Zenith
specs. She was making a, admittedly "hard", short field landing on a paved
strip at a high angle of attack when it happened. The main gear touched
first and was not damaged.
Like most of us, I have made some awful hard landings in my 701 but have
been relieved to find little or no gear damage. Until I learned about this
failure I thought that 701 gear was very resilient. Now I am beginning to
wonder.
Have any of you seen or experienced a similar collapse or speculate as to
its cause?

I too have made some hard landings in my CH701. I would think that if the
main gear properly touched down first, the nose gear would at worst case be
jammed vertically.
These two photos look like the nose gear hit first. Looks like the plane
was in a nose down attitude and just bent the tube. Since the axle was also
bent, that must have been a hard strike.
Just my thoughts.

First I've heard of any problem, have been on the list for 5 years or better. More
info is needed, such as what precisely does built to factory specs mean? The
tube should have been 2" .065 wall 4130. Damage like that I would have suspected
some sort of rupture in the tube. It is curious, I wonder if a substitution
was made.

Les,
I can tell you that it was a very hard landing. Just look at the axle on the
nose gear, it takes a lot to get that to bend. My guess is that it was
either porpoised in and got out of control or it did not hit the mains first and
hit the nose gear first.

Any chance the front wheel bearing was tight or seized? She might inspect

Wow. If anything this reinforces how stout the 701 is.
How do you repair that damage? You would need to build a new floor pan
complete with the frame rails and probably a new firewall as well.
DO NOT ARCHIVE
Is it possible that this was caused by a stall with a break just before the
mains hit?

To all=2C
recently had an event with a 701. Touched down on mains and when th
e nosewheel lowered in a light to moderate manner the aircraft started to v
eer to the left . Right foot had no effect and the rate of turn increased r
esulting in the left wheel lifting and the right wing leading edge slat con
tacting the ground
I was concerned that I may have applied right foot to the left rudder pedal
on the other side which could be a danger with the peddals so close togeth
er=2C but wondered if that was the case why this had not happened before
We dicovered shortly after buying the aircraft that the nosewheel axel was
bent and I am now tending to think that the veering off to the left was due
to failure following a prevous incident or number of incidents.
Any thoughts or theories welcomed . Heck of a feeling when you put an imput
into the controls that you have done for many years and hours and have no
response.

as per Bob
I had similar damage when I lost a GSC propeller and had to land in a
sugar Cane paddock.
I suggest they look harder at the main gear If this landing was that
hard the main gear will be damaged.
The final part of my landing was a stall from approx ten feet.
I had similar damage to front gear, rear gear straightend out damage to
back of cockpit at Wing attach points
wind hit the ground after the initial impact and bounce. Hard
landing!!! distance 30ft.
Aircraft would be considered a write off but being a Ch701 I rebuilt it
2 years ago.
I also have messed up and had some hard landings and never bent any
thing.

It bothered me when I built my 701 that the nose wheel axle was made of
thin wall 4130 tubing with nuts welded in each end. I threw it away and
built a new one out of solid solid stainless steel. A little more
weight, but so what!! It will not bend. Larry, N1345L

Subject: Zenith701801-List: Re: Gasoline smell
I have experienced the described "smell" as well since first flight. I have
inspected the fuel system several times for any leak and found nothing. I
recently ordered new fuel line that is claimed to not out gas through the
side wall, at $5 a foot from AS. I will let you all know if this solves my
fume issue.

Tony.
Two that I know of in California. One got it figured out before landing
and the other went off the runway and hit a walnut tree and then spun
into a fence. Both were right foot left rudder on co-pilots side.

Subject: RE: Zenith701801-List: Weak 701 Nose Gear?
To all,
recently had an event with a 701. Touched down on mains and
when the nosewheel lowered in a light to moderate manner the aircraft
started to veer to the left . Right foot had no effect and the rate of
turn increased resulting in the left wheel lifting and the right wing
leading edge slat contacting the ground
I was concerned that I may have applied right foot to the left rudder
pedal on the other side which could be a danger with the peddals so
close together, but wondered if that was the case why this had not
happened before
We dicovered shortly after buying the aircraft that the nosewheel axel
was bent and I am now tending to think that the veering off to the left
was due to failure following a prevous incident or number of incidents.
Any thoughts or theories welcomed . Heck of a feeling when you put an
imput into the controls that you have done for many years and hours and
have no response.

Les,
I can tell you that it was a very hard landing. Just look at the axle
on the nose gear, it takes a lot to get that to bend. My guess is that
it was either porpoised in and got out of control or it did not hit the
mains first and hit the nose gear first.

I was told by both pilot and passenger that the mains did hit first and the

Maybe the nose came down hard after the mains ( total stall with break the
instant the mains hit, loss of elevator authority, ect )?
