R44 Clutch Actuator
Hi all,
My 2008 Raven 2/ 430hrs is in for an Annual.
I am told that the Clutch Actuator has 'failed the switch test', taking 'four seconds as opposed to the allowable two' and needs to be replaced.
The part is well over three thousand pounds.
Does anybody else out there have any similar experiences?

This is does not sound right to me. There is a test that uses a connector you plug in but that only tells you if the limit switches are working correctly. If they are not then they can be replaced.
In terms of the clutch actuator. In the run-up procedures you have 70s for the clutch to fully engage.
Ask them to show you in the maintenance manual where there is 2 s/ 4 s limit is. If they do can you please come back and list the pages.
You also have a PM Hairyplane.

Sounds like another leg lifting exercise, no doubt by one of the big "professional" Part 145 outfits.
R44 MM Page 2.25, describes "Method 2" for testing the actuator (manually depressing the column springs), stating that if the motor runs for more than approximately 2 seconds, stop for a moment then depress the spring again, if motor runs again then replace the opposite switch per Section 7.551.
Switch P/N: C053-2 - List Price $165

His helicopter is new enough that you would not use that method. It will have the link on the harness to insert the switch. Someone is trying to take the piss big style.

Thank you!
Hi all,
Thanks for all the advice/ PM. I am very happy with my CAMO and have remained loyal to them since they trained me and sold me my first brand new machine 9 years ago.
I'm sure they will be perfectly relaxed about their customers sharing their experiences.
I promise to report back.
All the best.

What could cause the alternator light to fail to illuminate in a Raven II?

Re the video posted by 206fan:
Did I see what I thought I saw? He landed hard enough to spread the skids on what looked to like rows of cinder blocks, then got passengers out and simply took off again??
Is that what happened???

Looks like it. It also looks as though his first lift was before RPM was in the 101/102% range (governor not kicked in?). Engine note changes before 2nd attempt, but he looks mighty heavy for a downwind departure..
EASA has proposed the AD for R44 Fuel tanks replacement (24 months):

Proposed AD from the FAA regarding blades as well. Owning an R44 is about to get expensive.

We knew this was coming. It's all well and good for those of us who have been in helicopters for years and who can interpret the previous FAA AD as sufficient warning, but the problem is RHC are selling their products to many first time owners who are suckered into helicopter ownership by their flying school (don't get me going on the lies told of operating costs and free flying with the magic 'leaseback' to the school..). All this with the completely disingenuous 'promise' of fixed costs over a twelve year period between overhauls. I'd laugh if this wasn't so dishonest. I doubt there has been one R44 that hasn't suffered an AD clout like this in its first twelve years. RHC should drop any claim to fixed term costs - they now look ridiculous. This blade AD has effectively written off every non-hydraulic Astro - only 300 left in the world apparently - customer go hang, again. I had the good sense to sell my Raven II and assist another friend in selling his - both went overseas. Good riddance - now happily behind a diesel in my DA40. To the dark side, over and out.

I have to admit that the PAD issued by EASA got me a little bit confused.
Talking about the SB for the fuel bladder tank to my local aviation authority about a year ago they told me that neither them nor the EASA saw any use in turning it into an AD. One year later they suddenly do.
Can somebody please enlighten me how the fuel bladder is attached / installed in the tank. I heard that it's not completly attached to the tank but only at the filler neck and that there have been the first reported cracks on the neck.
What about all those other helicopter in the world flying around without fuel bladder tanks? Our H300 doesn't have one either. Will we have to replace those tanks as well pretty soon?
