Just for evaluation...



Group 4 ship, long time in storage.
Picture of area between fuel tank and cockpit. No other info available.

Another subject of "vibration case" ?

 

[9aplus]

Can be single "hard" landing or even simple belt slip too...
Opinions?

 

[akoschier]

Whats the question

Whats the question

I am kooking at a fuzzy picture of the lower right hand fuel discharge fitting and associated plumbing, but am not so sure what the question is about.

White marks on gell-coat on right side, tank or cockpit is traveling or oscillating
against each other, allowing metal parts of plumbing to crash on gell-coat....

What can be the source of such banging?

 

[bryancobb]

Do we know for sure these marks are not from mechanic wrenching or during original assembly? Are you the owner? Is it a smooth machine?

 

[9aplus]

No we do not know.
No.
Do not know.... machine is in storage, long time.

That would be a result not cause. pylon whirl would be a cause, Was the cabin remove for work?

 

[9aplus]

So far I know, no removes after initial build...
Unfortunately, the test pilot is no longer with us,
to testify about performance.

There is no way the tanks and cabin are making contact. The crossover line does not appear to be stabilized and could be moving around. I would bet It is caused be mishandling of the cabin during installation. Stabilize the line and fly it. If there had been pylon whirl, blade shake or any other major issue, these scratches would be the very least of the damage.

DITTO For sure...

 

[9aplus]

Thanks to everyone for the tips so far .
Just trying to assess the level of required works necessary to
bring back in flying condition.
Sources of craft history are limited.
In that case some smart choices of
approach to safety are necessary.

 

[birdy]

9aplus, look at the picture carefuly, the marks you are looking at are just a reflection.

I cant believe noone else can see it.
I thort i was blind.
Apparently not as blind as sun.

 

[9aplus]

Sorry Birdy,
sun is not shining on that real scratches

 

[birdy]

You dont need sun light.
you only need enough light for thr camera to record.
If theres that much light, then theres enough light for a reflection.

in small details ->

Hi Djani - has this machine got a previous registration - I may/may not be able to trace some history.

Cheers

 

[9aplus]

Sorry Steve, not possible...

No known incident or crash record, overall looks like in decent condition,
main blades stored - no dents,
logs available with only short note of some belts slipping from
test pilot, who perished in non related aviation incident.
Logs entry are signed only by that pilot.

My personal opinion is that craft was subject of some level of hard landing,
or even drop - can be from trailer or during hang test by someone else,
which is not recorded in logs.

Thank you for such kind assistance offer...

Those are all just reflections of the ground/shop floor under the tanks. Nice shine on the paint job.

Edit: Looking closer, I think it's the reflection of the cyclic mixer.

 

[hillberg]

have some one hang the ship & put a load in the pilots seat, Won't be the first time a cabin yielded under a load.
