The logic of this eludes me but it is not uncommon. I once bought an Exp A/B Titan Tornado 912 that was reasonably well maintained. It was built by an A&P who rebuilds aircraft engines as his main line of work. The only logbook entries for the Titan were oil/filter changes and annual condition inspections, though I'm sure he did a lot of stuff that was not logged. I asked him about it and he said I only record what the FAA requires. Since SBs etc are not required on Exp A/B he never recorded them. Regarding Lucien's comments about expensive annuals: As you know, the inspection is not a maintenance and/or repair activity, except for the engine cleaning and oil/filter change and other minor stuff like gapping plugs etc.. Generally a mechanic/inspector's flat charge is for doing the inspection only. Remedial or corrective work is not part of the inspection but often required for return to service. We always issue an inspection report before doing any corrective work for two reasons. One is that any corrective work should be discussed with the owner so he can choose which (if any) of his options for corrective measures is done. Two, we've not been contracted to do any corrective work until the owner gives us the go-ahead and therefore he is not obligated to pay us for this un-contracted work. One of his options is to not get the work done at all. If the work is elective in nature but not required, then we can return the aircraft to service without it being done. If it is required work, then he can say don't do it and we do not return the aircraft to service and that is part of the logbook entry. If he flies away after paying our inspection fee, then our liability is ended there except to notify the FAA of what we did. -------- Thom Riddle Buffalo, NY Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x31 I have reached an age when, if someone tells me to wear socks, I don't have to. - Albert Einstein Read this topic online here: http://forums.matronics.com/viewtopic.php?p=278778#278778 ________________________________ Message 2 _____________________________________ Time: 05:46:54 AM PST US Subject: RotaxEngines-List: Re: Your Mechanic May have Just Cost You From: "lucien" Thom Riddle wrote: > Some mechanics log as little as possible in the hope that they will avoid some liability.

A couple other thoughts I have on logging and inspections: On an experimental airplane, I don't see the logic of not logging any work or inspections you (the owner/op) do. Unless you're actively trying to evade some rule or law it doesn't make any sense to me. I'm the one risking his neck flying around in the air in the thing, I also don't have a photographic memory so I need some kind of record of the maintenance/repairs/checks I've done and not done on the plane so I can keep track of what's coming up. I usually can't even remember when I changed the oil, what filter I've used, tightening torque used, if I checked the mag. plug etc. So that goes in the logbook when I do it so I have a ready reference for when it needs to be done again. My personal opinion is the logbook is there for _me_ to know what state my airplane is in at a given time. The legal requirements I consider to be minima but I try to maintain a higher standard for myself. As for the legally required inspections, they're well intended but in actual practice they can do more harm than good. I used to live in TX where cars had to have "annuals". A good idea in theory, but in practice one of the cheesiest, snivelling scams ever come up with by a state govt. The intent is not public safety, but more sinister motives like getting a particular type or age of car off the road. For aircraft, the situation is much better but I still believe you need to cover your tail at all times. Like I said, things can be missed and you can't always trust your mechanics. And the rules are inappropriate in some cases, like when you have an LSA/912 class plane like mine in the EAB category - here the rules are unsafe in that they require annual CI's by unqualified/untrained mechanics. Here the owner/op has to be doubly careful. Luck is your only allay here - your AnP may be familiar with your engine/airframe, but they also may not be. But in all cases, IMO, the responsibility for the condition of my plane is ultimately mine so I have to accept that and be willing to do the work to maintain the plane. So that;s what I consider the logbook to be - a record primarily for me to keep track of the state of my plane. The legal requirements are, IMO, a very distant second function to that main function for me. Same with inspections. I don't consider an annual CI to be sufficient, so I do a kind of continuous CI of the plane on my own and record what I do in the logbook, legal or not. I like to be legal, but I far prefer to be safe instead if I have to choose between them and do choose safe every time.

Almost all are SLSA and very few ELSA except for engine work. To be honest, if my plane were ELSA and I lived near you or Thom, I'd still take the plane to one of you guys for at least the first CI (owner-assist of course), so I could see what a typical LSA CI really should look like. And I could benifit from your experience with my type of plane and motor, etc. Like I said, the LSA rule, tho I'm a harsh critic of it in most other respects, is a pretty decent attempt to close the hole in the EAB rule that I talked about earlier. I.e., get LSA class planes maintained/inspected by persons legally qualified to inspect/maintain them. As it is, my plane being EAB, I freely and willingly admit I'd rather the mechanic that signs off the annual CI do as little as possible and stay as far away from my engine with a wrench as I can keep him (unless he's actually trained and experienced with LSA's which is not the case where I am). That's a safety concern, not a rebellious-against-the-law one. Like I said, EAB LSA's where you're not the builder are a kind of edge case in the EAB rules where they actually lead to an unsafe situation that weren't anticipated so it's not really anyone's fault. My friend who has a 2nd hand RV doesn't have to worry as much as most of the plane is already familiar to the typical AnP, but I do have to be very careful. BTW, at my airport I and my friend with the RV seem to be the only nutcases that insist on full owner-assist annuals. Even my AnP noted last year that "yep... you two guys seem to be the only ones...". And even he has given up on owner-assist (an annual on an RV is pretty grueling). So I'm the only mental patient left who seems to want to do his own ;) LS -------- LS Titan II SS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=278786#278786 ________________________________ Message 5 _____________________________________ Time: 06:35:30 AM PST US Subject: RotaxEngines-List: Re: Your Mechanic May have Just Cost You From: "Thom Riddle" Lucien, As you are aware, many (perhaps most) standard category aircraft owners don't really want to understand their airplanes well enough to do even those relatively simple owner-allowed preventative maintenance items listed in the appendix A section C of part 43.

Yep, I'd kill for that. As there's still a lot about my plane and motor I still don't know (in fact I may be PM'ing you again on the carburettor overhaul issue here in a bit, something that still needs to be done). BTW, to my knowledge there's nothing in the rules for standard category that actually prevents the owner/op from participating in or even slap doing maintenance, repairs and even the annual - it's just that all the work and inspections have to be signed off by an AnP (and an AnP with inspector rating on the annual). Tough to find an AnP that'd be that permissive, tho. This year I think I'm actually going to go through the part 43 checklist on my plane myself in Feb. before taking it in. The AnP will still have to do it at annual but I don't think I've actually done the list before on any of my other planes.

Regardless of who does the preventative maintenance item it must be logged. Some owners think they can do it but don't have to log it. Not so; it must be logged to be legal. Some mechanics, if s/he knows you and knows that you do good and contentious work, will sign off on owner-assisted inspections. However, some mechanics will not do any work or inspection at all on experimental aircraft of any kind. In my experience that is much more common than those who will do owner-assisted inspections.

When we inspect an experimental, by the time we're done with it we know it pretty well. The first inspection always takes longer than subsequent ones, due to the learning curve. That's a good point. When I had my Kolb (FS II), I couldn't get an AnP to look at it at all primarily because of the engine (rotax 503). The airframe itself on all the Kolbs is really high quality probably the highest quality you'll see on a light a/c. it uses aircraft grade hardware, materials, fabric etc. throughout the whole plane. There's nothing goofy on it and it's all AN hardware, Stitts fabric and etc. so that's not too big of a deal for a traditional AnP to look at. But the engine just sent em running....... Unfortunately, that eventually led to me having to sell the plane, which fortunately the new owner had access to an AnP that'd be willing to sign off the CI. But I can see it and didn't fault them for it, since they have to put their signature in the logbook. PS: speaking of Rotax, is there a convenient way to check the timing on the 912? At my first annual, the AnP I went to asked how to check it and we couldn't figure it out. I vaguely remember looking in the maintenance manuals for this and couldn't find it..... I'm assuming its similar to the 2-strokes where you position the trigger coils just right in their mounts, but I can't see an easy way to visually check this on the 912?

As long as everything is fastened properly the timing is correct. On Kolbs it is easy to see these by removing the plastic cover. On tractor mounted engines it may be difficult to access this area. Fortunately, this is one area that rarely causes problems on the 912. The electronic modules can fail and the plug connectors must be well secured to the modules to prevent vibration caused problems. -------- Thom Riddle Buffalo, NY Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x31 I have reached an age when, if someone tells me to wear socks, I don't have to. - Albert Einstein Read this topic online here: http://forums.matronics.com/viewtopic.php?p=278795#278795 ________________________________ Message 10 ____________________________________ Time: 12:11:22 PM PST US From: Hugh MCKAY III Subject: RotaxEngines-List: Oil Analysis Report I have a 912 UL engine which had 228 hours on it when the oil was first ana lyzed.

Your oil analysis will fluctuate. Just look for continuing trends. With these readings both my reports stated they were normal. I have others at lower hour samples and they all fluctuate some. I would bet switching oils between analysis might change the results too. I will also depend on who is doing your oil analysis. I have been using Aviation Laboratories that do a lot of Rotax engines. I will say this, my best analysis and my cleanest mag plug checks are with AmsOil motorcycle oil. I use 20-50W in the warm months and 10-40W in the colder months. The mag plugs I see using Amsoil seem to be cleaner for my clients that use the Amsoil over other oils. My mag plug may have nothing at all on it and some of the other oils have mag plugs with fuzz on it. Just an observation from seeing 35 different oil mag plugs a year and at least 2 oil changes each. I use Amsoil in my Honda Goldwing 1800 too and it does make my shifting smoother and quieter. A little fuzz on the plug is normal, but clean seems to work for me, too. -------- Roger Lee Tucson, Az.

My mag plug may have nothing at all on it and some of the othe r oils have mag plugs with fuzz on it. Just an observation from seeing 35 d ifferent oil mag plugs a year and at least 2 oil changes each. I use Amsoil in my Honda Goldwing 1800 too and it does make my shifting smoother and qu ieter. A little fuzz on the plug is normal, but clean seems to work for me, too.=0A=0A--------=0ARoger Lee=0ATucson, Az.=0ALight Sport Repairman - Mai ntenance Rated=0ARotax Repair Center=0A520-574-1080=0A=0A=0A=0A=0ARead this topic online here:=0A=0Ahttp://forums.matronics.com/viewtopic.php?p=2788 =========================0A ==================== ________________________________ Message 15 ____________________________________ Time: 05:28:08 PM PST US Subject: RotaxEngines-List: 912 UL runs rough on 1 "mag" From: "ejessee" My 912 UL runs smoothly on the Right mag but rough on the left. I have checked all the plugs and they seem fine. I have had this problem for a while but it goes away when the engine warms up. I can't seem to get the engine warm flying -------- Ernest Jessee N4931M Read this topic online here: http://forums.matronics.com/viewtopic.php?p=278829#278829 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
