Good morning  guys,  

Does anyone know the requirements for the 912 gear box inspection at 600 hrs. ? Someone told us it requires going to a Rotax repair center and costs around 6 or $ 800 ?, and that an A&P can’t do it ?

If you have an experimental airworthiness cert, you or anyone

can do the gearbox inspection. It does require some tooling, a press,

and it would be unwise to perform without taking one of the rotax

courses in which the technique is taught.  I recommend Dean's

course at Sebring (aerotechnicalinstitute.com)



As for price for sending the work out, call your local authorized 

Rotax repair center. Don't ask here, it varies around the country.

Wow, I wonder about "anyone" can do the inspection.

The 600 hr is not the gearbox inspection, but the overload clutch. You can not do this yourself and will only bend your engine mounts. You will need bracing for the engine, a special 5' tool and lever. I hate to say this in writing, but you may want to forgo this if you have no one in your area to do this check, or fly your plane to a distributor, but ask them first if they can handle this inspection..

If you are using 91 octane then you don't need to do this inspection at this time.

Hi Bob,



I seem to recall when mine came due I sent it to Lockwood.  They turned it around in less than a week and I think it was less than a couple of hundred dollars.

Bob,



I do periodic gearbox inspections. Just did one a couple weeks ago and it needed new springs, otherwise it was in great shape. If you ship me the gearbox and pay for return shipping I will do your inspection for $100 plus parts. If it needs springs they are about $20 each. The gearbox with clutch uses three and the one without uses two. If the springs are within new specs, you don't need to change them, which is probably the case if you've been running mostly mogas.



If you want to fly your airplane here, we can turn it around in 1/2 day if no parts are needed but we charge for gearbox removal and installastion too. Since I am a certified power plant mechanic I can do the work on an SLSA. 



Or you can send it to Lockwood. They will change the springs whether needed or not.

Roger,



We've not done one yet but I understand the process and am confident that we can set up an engine brace/support jig for doing so. I spent most of my engineering career doing machine design so this should be pretty straight forward. Since each airplane type is a little different, it will require a slightly different setup for each airplane type.

Re Gearbox inspection:



Hi Roger,



I dunno, but when I took Dean's Maintenance course at SnF 2006,

we took a gearbox apart with a bench press and couple of doodads

which I am too far away to look up at the moment. We inspected the 

dogs, gears and seals.  I don't remember a slipper in the box we

cracked open, but then my engine doesn't have one anyway

Hi Rampil,



We may be talking two different inspections. One is the overload clutch in the engine and the other is the gear box. Two different critters. The gear box one is easy. The overload clutch test can bend and tweak engine frames. Your talking about the gear box and the other one mentioned above is the overload clutch at 600 hours. The gear box is 800 hours with 100LL.
