We had a blade strike on one of our 350's in november last year. Sent the engine to Turbomeca for inspection and are still waiting to get it back. Will get it back in the end of february they say, together with a big bill. nothing wrong with the engine but they had to do some SB's and such, which is OK, but 4 months! As far as I know Eurocopter is producing five 350's per week which means that Turbomeca has to produce five engines per week so I find it totally unacceptable that they are using 4 months for an inspection!!!

A BA at 4630 + 300 = 4930
A B2 (or B3) is good for 4961 (IGW) You'd save more than the 30 lb difference on just the weight of the engine , I'd expect ?

and like them.work well,need particle seperators though,bleed bands get dirty easy and if kept clean,give no probs.smokeless lines gives a clean tailboom.
quieter machine also.

I heard there was going to be a Super-D "2" as well. Would be a great helicopter.

BA Internal is 4630 lbs and 4988 External.
Soloy BA is the same as the BA.
There is a SB regarding changing a B or D to a B2, you can order a kit from eurocopter that includes 355 Tail & Main blades, Arriel 1D1, and various other parts for $550,000 Approx. All you do is trade in you tx'd 1B and send back the 350 blades. Quite a few Canadian helicopter operators have completed the conversion.
The last two 1D1 1st overhauls I delt with had a turn around of just under 3 months. The last 2nd run 1D1 overhaul took 3 and a half months. The 2 1st run overhauls went to 3000 hrs for the overhaul and the last 2nd run went 2840 hrs when it was sent in for maintenance convienience. There is a 2nd stage wheel replacement to be completed around 1500 hrs now but Turbomeca eats most of the cost for the re & re and pro-rates the wheel based on hours used before replacement. :alien:
I do think an option to the Arriel 1D1 will only help operators in the long run. Having choice makes everyone compete harder. The only concern I would have is if they do certify an Arriel 1D1 equivalent for the B2 is that it is reliable, cost effective, and a true replacement.

Eagle Helicopters who were doing the Super D upgrade with the Lycoming engine said they were planning a B2 equal but have had a pain in the ass dealing with Honeywell re the new engine so that project is moving nowhere fast. Will be great when it finally comes out.

We have one engine where the turbine disk has about 1900 hrs since new. In the SB it says that when the disc reaches 1200 hrs since new you have to check the relative blade position every 150 hrs. So when we received this SB the engine had already passed 1200 hrs so we inspected it immediately and the blades were within limits. We do this check every 100 hrs because you have to be two persons to do the check so its convenient to do it during the 100 hrs inspection.
My understanding of the SB is that if the blades are within limits you can continue to use the engine until november 2006 when the disk and blades has to be replaced. The SB says something about 1500 hrs but the meaning of this is unclear to me. Anyway I asked these guys from Turbomeca if my opinion was correct and after some discussions and telephone calls, they said yes. You can continue to fly as long as the blade position is within limits.
Two days after they left I got a telefax from Turbomeca saying that we have to replace the disk and blades. Which is not exactly free of charge. It is not my fault that that there is something wrong with the engine so I think Turbomeca has to pay for this. But of course they will not. You get a 50% discount which is not bad. Since the Turbine Module now has a TBO of 1500 hrs instead of 3000 you might say that it is the same thing, but it is not.
So now I want an engine conversion on this 350. A PT6 would be the choice of my dreams but since you guys say that the LTS101 is a good one we will give it a try.
Any comments on this?
