Ground 350 run without blades?

That is real info. What does balancing a tail rotor have to do with Main
Rotor Blades? I'm a maintenance guy who has bee ground running helicopters
for almost 20 years. By the way Main Rotor Blades is what helps to make it
a HELICOPTER. Which bunch of Yahoos are WE? Any PROFESSIONAL ORGANIZATION
that the PROFESSIONAL avaition community might be familiar with???

You are missing the point. On 3180s & 315s one runs the machine without the
blades to centre a new servo. (If you don't have a hydraulic rig on site)
That is a standard practice. So one might as well do the tail rotor whilst
you are at it. AND Its a hell of a lot quicker than when the MRBs are
fitted. OK those machines have a clutch but I still say it would also be
quicker - and safer - to do maintenance runs on 350/355s, that did not
involve needing the MRBs, without them.

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.
