    --> RV10-List message posted by: "RAS" <deruiteraircraftservices@btinternet.com> hi, Can anyone explain why an AD or SB does not have to complied with because the engine is experimental? It is not the certified status of the engine that dictates issue of an AD or SB, but the parts that have been used to built the particular engine which dictate the issue of an AD or SB. I do not believe that Lycoming does this as a money spinner, whomever has read the SB569 knows that the Crankshaft kit is made available for $2000, this is not even half the normal list price of a four cylinder crankshaft, let alone the price for a six cylinder crankshaft. In addition to the crankshaft itself, the kit comes with bearings, nuts, bolts, etc. In an ideal world engines are built and run 1000hours past their TBO with nothing more than a regular oil change. This is fantasy. This little exercise is costing Lycoming quite a few $$$, and therefore should be treated a bit more serious than some people seem to suggest on this forum. The reality is that a lot of the 500 odd builders haven't even got an engine, and that those who do, have not got to the stage where the engine is actually mounted. It is not that much work to split the crankcase in the overall scheme of building a RV10, and the $2000 for a new shaft doesn't really compare to the investment for the a/c kit and all bits and bobs to be got to complete the project. Another thing to consider, in particular for those who haven't got their engine yet, is to take the SB569 with them when they go and look at an engine, you know what the pitfalls are when you buy one that's on the list! Oh, and yes, our engine is effected and the crankkit is on order, good deal if you ask me, 0 hour overhauled bottom end for $2000..........

    --> RV10-List message posted by: "Rob Kermanj" <flysrv10@gmail.com> Mine is located at the wing tip. I could not fit any more wires to the aft fuselage so I decided to install it in the wing tip. The AHARS is installed in the forward fuselage and leveled with the canopy rail. That way, I will level the magnometer with the canopy rail. I do not have any strobes in the wing tip soI am not sure how it might effect the magnometer. Talk to Todd ot Geff at GRT.

    Subject: Re: GRT AHRS/Magnetometer Location
    GRT AHRS/Magnetometer LocationFor what it is worth, as I have not yet flown, I mounted duel AHRS and duel Magnetometers side by side on a shelf I built behind the baggage compartment. The shelf is anchored to the upper side longeron's and I nutplated the shelf to the cross members so I could remove the entire shelf with the AHRS and Magnetometers in place. Since the wiring comes up from underneath the baggage compartment and the shelf is only 14" wide sitting in the middle of the cross members, it is easy to hook up the AHRS and Magnetometers before screwing the plate onto the cross members. I put the nutplates in so that I could set the shelf on the cross members and then screw the shelf on from underneath.

    From: "Condon, Philip M." <pcondon@mitre.org>
    --> RV10-List message posted by: "Condon, Philip M." <pcondon@mitre.org> Someone posted yesterday that their (or all) of VANS IO-540-D4A5 are NOT subject to this action. A word of caution here....the Lycoming SB/AD DOES mention the IO-540-D4A5 as a possible candidate for the Crank problem. Read the front of the SB/AD, check the number on the crank flange and the serial number to verify. Of course, if a rebuilt engine was done within the time frame indicated by the SB/AD then further investigation is warranted (shop records, part ids, repair billing records, assembly records & log book entries). Total Lycoming bulletin is on Mikes website (Thanks Mike) http://www.mstewart.net/deletesoon/sb569.pdf

    Thanks Rhonda, I was sort of trying to be rhetorical on this comment...I'm sure Van's are a Lyca as who else would build a Lyca and be sold as a Lyca except the folks in Williamsport...but the parts come from the subcontractors and one needs to know more about the various major engine parts, than just who the seller was on the main name plate. I know my buddy recently replaced his cylinders--with ECI Titans...the paper work arrived and ECI had all kinds of errors in the paper work as to the numbers etc...they had sent this out to many repair stations who have similar the repairs...the A&P noticed the problem, discussed it with the FSDO, they took it up with ECI and now ECI is making correction on the Titans...that's only a paper problem. But before a lot of folks on here get thinking "it experimental" so I'm OK...you'd hate to be sitting in the weeds upside down on fire and thinking: hey that crank was ok when it went bust because after all it's an experimental engine and I, with that repairman's licenses, said so...there potentially, may be some really poor cranks out there...IMHO.

    --> RV10-List message posted by: "John Hasbrouck" <jhasbrouck@woh.rr.com> I've been following the thread re: Lycoming crank AD and trying to follow the distinctions between Certificated and Experimental and who can work on what. My question is: can I, as a builder, buy an existing Lycoming and overhaul it without an A/P or I/A being involved, hang it on the airplane and fly it within the current regs? Does this then require a 40 hour fly off or 25? Ignore, for the time being, the wisdom of this move. If the above is within the regs then an A/P could look over my shoulder and not have the liability of having his name in the engine log. As far as the SB/AD question, the point is moot. As has been said before, nobody wants bad parts in their engine. The FARs cause me to fall asleep and when I think I know them someone always comes up with another interpretation.

Mike, can you help me put a boat prop, probably a 23 pitch (top end speed) on it. The only way I figure I'll get to go to the RedBull races is to power the engine over there myself. One good thing about it, the engine would be pretty well broken in by the time it gets there :) Allen Do Not Archive -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Stewart, Michael (ISS Atlanta) Sent: Wednesday, March 22, 2006 1:01 PM Subject: RE: RV10-List: O/OI-540 overhaul question --> RV10-List message posted by: "Stewart, Michael (ISS Atlanta)" <mstewart@iss.net> Of course. You could break down the lyco, install Briggs and Stratton heads, A ford rear end, drive a boat propeller, and attach a kite and go fly. Just make sure your kite has the N numbers properly applied.

My question is: can I, as a builder, buy an existing Lycoming and overhaul it without an A/P or I/A being involved, hang it on the airplane and fly it within the current regs? Does this then require a 40 hour fly off or 25? Ignore, for the time being, the wisdom of this move. If the above is within the regs then an A/P could look over my shoulder and not have the liability of having his name in the engine log. As far as the SB/AD question, the point is moot. As has been said before, nobody wants bad parts in their engine. The FARs cause me to fall asleep and when I think I know them someone always comes up with another interpretation.

I had the prop flange on my O-360 crank fail ..... and the prop, flywheel, and spinner departed the plane as an assembly. There I was, in a glider without the endorsement on my license! I rebuilt the engine using a crank manufactured by Moldex, with a beefier flange! This is definitely an 'experimental' engine, and the 'bogus' crank is in the engine log, along with all the parts replaced or overhauled. > Does this then require a 40 hour fly off or 25? That I can't say. I didn't ask anyone about putting the plane back in service since I hadn't really changed anything except the crank .... which was built to Lycoming's specs and the exception for the thicker prop flange. Actually, I was remiss in not going back to the 30 mile 40 hr. restriction ..... I just flew it locally for a few hours to make sure that the temps, power, oil pressure etc. were OK. > Ignore, for the time being, the wisdom of this move. What's wrong with your scenario??? You need the overhaul and parts manuals (the parts manual is specific to your model engine) and some tools from your toolbox. These engines are rock-simple, and everything you need to know is in that manual. Do you think overhauling your aircraft engine is any different form overhauling your car engione with a "Motors" manual??? > If the above is within the regs then an A/P could look over my > shoulder and not have the liability of having his name in the engine log. This is true. And a good move, in my opinion. I've played mechanic (a financial necessity) most of my life so I'm familiar with tools needed. > As far as the SB/AD question, the point is moot. As has been said > before, nobody wants bad parts in their engine. AMEN! > The FARs cause me to fall asleep and when I think I know them > someone always comes up with another interpretation. I second that!!! They're written that way so the feds can nail you if they want ..... and you haven't done 'anything wrong'. IMHO, of course!
