Ground 350 run without blades?

What does the manufacture have to say on this matter. They write the
maintenance manual.


I'm checking the 350 manuals but nothing so far.

The running 315/3180 without blades was shown to us by the factory rep
when
we first bought it.

Factory rep or not, if it isn't in one of the maintenance manuals as
one of the proceedures, you would be wise not to do it. One of the
concerns I would have is the affect on other components without the
inertia of the main rotors in the system. Could you unknowingly
damage something in the driveline? The manufacture is the best source
for figuring this type of thing out.


Yes, there is nothing in either manual.
I've checked with a couple of engineers who worked on Alouettes they all ran
them without blades. It's a standard procedure. (How else are you going to
change a servo in the field?)

Slatts,

From your last posting see UK in the link above. I had thought you
were located here in the US. Sorry.

In the US, to be a standard maintenance procedure it better be in the
current maintenance manual. Short of that, it needs to be in a,
Service Bulletin, Advisory Directive or some type of written process
from the manufacture in order to be acceptable to the FAA. Performing
any maintenance without something acceptable to the FAA and you are
setting yourself up for loss of license and possible legal liability.

Sorry to say I have no suggestion to help you find what you are
looking for.

That is unfortunately is what is starting to happen here. In the past when
one signed on one's licence you took the responsibility for what you did.
Nowadays when one signs on a company approval as you say if it is not in
the book somewhere it can't be done. I guess with old fashioned machines
that was not a problem but now they are too complicated for one person to
use his judgement :-)
I'm talking about machines where the M&O manual was less an inch thick as
opposed to some today where they take up six feet of shelf space!
