Canadian R-44 at 2200 hours

01-05-2015 03:40:09

I am aware of the Robinson edicts for overhaul, but what is actually required in Canada to fly a machine that is over 12 years old.

Hello Simon,
Is your R44 at 2200 hrs or 12 years?  RHC has placed the life limits on certain components and you can either perform a 12 year inspection or a 2200 hr inspection (depending on where you are at in the aircrafts life).  I am the DOM for a Canadian AMO (RHC approved service center as well).  We look after private and commercial Robbies.  The Canadian Type Certificate for the R22/R44 is pretty much a carbon copy of the U.S. type certificate so you are pretty much committed to following the life limits laid out by RHC.  Remember, if you choose to fly your aircraft past either an hour or calendar life limit you are leaving yourself wide open for trouble (I'm not saying that at 2200.1 hrs your aircraft will fall out of the sky), but your C of A may become invalid because you chose to fly past a manufacturer's posted limit.  If you would like an official answer, I would call your nearest TC office and talk to an inspector (ask for someone in Airworthiness) and have them explain it to you.  Personally I don't recommend you fly past any posted limits, its just not worth it.

Thanks for that thoughtful reply. That is why we all come here.
My machine is a year away from 12 years but 400 hours away from 2200. I don't fly that much to fly the hours off before the fateful 12 years.
I fly it for fun and my own business ventures. So the life I am saving with proper maintenance, is my own.

I was told from TC (maintenance and manufacturing) a few years back that because the way in which the maintenance manual was written for the R22 that one could still obtain a C of A and fly past the 12 yr recommendation if the main and tail rotors were replaced. This is for private use only. He also said that the same was NOT true for the R44 and that it could not be flown passed the 12 yr / 2200 hrs, again was down to how the maintenance manual is written. Don't phone your local TC office because everyone seems to interpret the written word differently, go right to the top of the food chain if you want the right answer.
Long story short, your SOL with the R44 after 12 years but check it out for yourself.

Yes, when it comes to TC, one does get many different answers sometimes!.  I usually make them (TC) commit to putting it down in writing and then one usually only gets one answer!  The Main and Tail rotors are the only 12 year items listed on the Airworthiness Limitations section of the R22/R44 MM.  My advice is fly the machine till the 12 year limit or the 2200 hr limit (whichever you hit first) and then overhaul the helicopter IAW the RHC manual.  When you order the kit you will get the new M/R blades (no AD), the bladder tanks will be included (if not already done) and the new T/R will also be included.

What I have so far is that there is a 12 year inspection and all the 12 year life limited parts have to be changed, the most expensive of these are the main and tail rotors.
But, the machine still times out at 2200 hours.
So I am looking for a used set of R-44 l  Clipper rotors with about 5 years left on them.
Any one got any leads on those?

Simon, please have a look at the R44 MM Section 2.600, the 12 yr O/H is listed there.  There is more to it than just changing the M/R & T/R blades.  If you then compare the 12 yr to the 2200 O/H, you will see they are not that different in terms of requirements.  Sorry, we do not have any of the C016-2, -5 blades in stock.
