correct me if i am wrong, they just overhauled your old governor, it was not replace. If that is the case chances are you have a Hartzell D-1 governor. parts for the D-1 governor are limited and you will not find new fly weights out there so if yours were not serviceable the prop shop would have been telling you you need to buy a new governor. what that all means is that your governor should be operating like it did before the overhaul, the fact that it is not means that some thing is not completely correct with it and should be checked out. I know that is not what you want to hear but there is nothing that they would have installed or replaced that would tighten the governor up so much that it takes over 1900 RPM to operate the prop. if you do nothing else, call a reputable prop shop and tell them what you have and what is going on and see what they tell you.....I think they will be telling you to pull it.

Bob, you should be able to change them out yourself with no issues, but I recommend you have a few specific tools available: feeler gauge torque wrench anti seize pulling the old plugs is self explanatory but be sure to use 2 wrenches to keep the leads from twisting when you remove them and do not handle the connector or spring. also be careful you don't drop the plugs (you may want a back up set of plugs) when installing the new plugs double check that they are properly gapped (I have never needed to regap a new set of plugs) once again be careful not to drop any or you might as well just throw it out because it will crack the internal ceramic. apply a dab of anti seize to the threads and install the plugs torque to 30 foot LBs then reinstall leads. the leads should be snug but not overly tight about 1/8 turn more then finger tight. found a good slide show that does a better job then I do at explaining the process. http://www.slideshare.net/razdjp/how-to-install-aircraft-sparkplugs Brian

by installing this system you do not automatically become FIKI certified. this system in lancairs and many of the other aircraft it has been installed on is for the inadvertent icing that you might run into along your route of flight. could it be FIKI certified...yes it could but that is a FAA process requiring engineering data to be gathered for the individual model of aircraft requesting certification, and flight test to be performed. the whole process is long and expensive for very little gain. on a side note the FAA recently issued an AD prohibiting some of the cessna 300 and 400 series aircraft that were thought to be FIKI certified from flying into known icing.

Paint has changed a lot over the years and even if you had the brand and codes the paint available today would not be the same and after 20+ yrs the original color would have weathered and faded. The easiest and best thing you can do is just have the paint color matched. Brian

From the added info it does sound like a prop governor issue, that needs to be looked at, glad everything else is normal.

clh I agree with the prop Balance, but i disagree that the 2 bladed have more vibration. the amount of vibration is determined by how well balanced the assembly is not the number of blades, but a three bladed prop will give you a different frequency of oscillation then a two bladed prop. as for being noisier... yea three's are probably quieter but i don't think it would be really noticeable. as for 2 bladed props, they are more efficient then the three.

Bob. have you done a dynamic prop balance?

well at least you provided the flowers

the cover was a little disheartening, why would you put a mooney inverted headed towards the side of a mountain on the cover?

Yes, That is the one Lancair has flown all over the world, It is also the first one to have the termawing installed...actually RDD calls it Therm X (they were involved with the development)

most of the Evo's are turboprop, there are 2 out there with lycoming EI2 piston engines installed. the first one is the prototype with Lycomings prototype engine, the second is has just been finished and as of last week was being test flown. I am not sure if it made it down to sun N fun but the goal was to put it on display.

this just reminded me of an issue we had with a Lancair IVP, the engine was new when installed and had about 60 hours logged, the new owner was flying with an instructor (also a test pilot) doing type specific training. they initiated an emergency decent and had a prop overspeed to 3610 RPM, they pulled power back and never touched it again until they landed. post analysis found the prop could be wobbled on the crank shaft due to the prop bolts stretching, and 2 of them breaking. the engine had to be sent out for overhaul, it required a new crank shaft along with most of the other internal parts. the prop was scrap. the cause of this 100K fiasco.......the original builder of the plane did not remove the shipping gasket before he installed the new governor, the gasket partially blocked one of the oil ports allowing the prop to appear to work but under a sudden load change it was not able to compensate fast enough. Brian

I do not actually install them, there are a couple of shops around the country that do, RDD in oregon does the Lancair installs and I think they run around 27-30K for the install and around 50lbs in loss of useful load. I am sure this could be installed with a field approval but the FAA will probably want to take a close look at the data before signing off on it. if you want to make the investment you my be able to work with the manufacturer to help them get an STC for the mooney model, same wing on so many versions and the factory starting production again it would make economic sense. Brian

yep, that is it, they just pulled that silver cap and installed the probe.

ok, read your post that posted while i was writing mine....why wold your mechanic send you flying with oil pressure that wasn't in normal parameters?...not that you will able to answer that. I highly recommend not flying again until you figure out what is happening, and please post more detailed info on your engine readings during run ups and your previous flights after the overhaul. Brian

Not to beat on you, but if your oil pressure was not up in the proper range during run up you should definatly not have gone flying, especially since the engine was just overhauled. lack of oil pressure will destroy a new engine as it is trying to break in and seat the new components. as for your mechanic being 45 min away and busy....is it worth 25K not to call him?

up stream of the cooler, the down stream side will be returning to the sump Brian

pulled a pic off the net. this is a remote filter installation, you can see the temp probe right on the top

Chris and Bob, the probe is on the back of the engine installed in the filter/vernatherm housing. I'd post pics but I am working at the job that pays my bills.....eerrr well i'm suppose to be working..... Brian

astelmaszek was a little harsh but 100% correct, if the engine/prop is not operating properly don't go flying! you could be dealing with an internal leak, faulty governor, It could have been an external leak the didn't show up during previous runs. the prop is controlled by oil from your oil system, and any issues with that can scrap your engine quickly and make for a very bad day. Brian

We have been putting the Thermwing on the Lancair Evolution and I haven't seen an installation that looks smooth (to the companies credit they are working on new installation techniques), I know they have tried them on other aircraft and I am hoping installation on a metal wing looks better. as for operation they seem to work well from the current feed back I have been getting. as stated above they do need their own power source due to the heavy electrical draw.

I have been experimenting with pulling my RPM's down to 2000, I have done it a few times now and comparing part of the flight at 2500/WOT and 2000/wot the smoothness is about the same the FF is 2 gph less and my airspeed has been dropping by around 4 Kts. as stated above that is not a lot of time difference when taking a trip, but it is a heck of a fuel savings. since I am still in the testing comparing stage I haven't kept the RPM low for the entire cruise portion so I can not do a time comparison for a point A to B trip. I guess the biggest trick to this testing is finding the most efficient blade angle to RPM in order to get the most efficiency out of the engine/prop combo

I like it

I bought my daughter an Ipad 3 wifi at the same time I bought my Ipad 3 with wifi and cellular, since both now have cracked screens I think I have decided to fix both screens and let her have mine. then I'll buy a Mini with cellular to replace mine and use her Ipad 3 as a secondary. every thing I have heard indicates they both have there advantages and I like the idea of yoke mounting the mini more then the full size Ipad. with my full size Ipad mounted I do not have a lot of room by the yoke grips and the mini will correct that. thanks for all the inputs Brian

I already have one on the way but the wife ok'd me replacing it so I have to decide what I am going to replace it with. as for the ZAGG case, they look good, the targus case i was using has done a pretty good job protecting it, I think i just dropped it one too many times. Brian
