    The key is to have all of your build logs with hours detailed, add all those up in a spreadsheet, and ensure that the total exceeds the minimum 4800 hours for all of your airframe and powerplant work. You need that and FAA form 8610-2 filled out. Use your spreadsheet as a continuation sheet for your experience. It also helps to have a recommendation letter from an A&P who is familiar with your work. You make an appt with FSDO maintenance inspector and he will spend an hour or more ascertaining your familiarity with maintenance, then sign off, approving you to take the tests. There are 3 writtens, and oral and practical. Contact me off list if you need more info.

    I built an RV7A. I am now working at Ft. Campbell, KY on Blackhawk helicopters. When I visited my FSDO with my letter from work, It was what I needed to get my tickets, I had worked there a little over 2-1/2 yrs, which is what was required. I asked about the time I spent building my RV7A and was told that does not count at all. But I agree with the other message check with your local FSDO.

    Subject: Sample maintenance log entry
    Greg=2C Your time spent building and maintaining your amateur-built aircraft can co unt towards your 18 or 30 month time requirement. How much will have to be determined by the FAA inspector that will need to sign off your applicatio n. I can tell you that you will need to also get a considerable amount of time working on type certificated aircraft to qualify. And I can also tell you that very little time will be able to count towards the powerplant por tion of the rating. For that side make sure you document any time spent ch anging cylinders and/or anything bolted to the engine as it came from the f actory (i.e. alternators and exhaust systems are airframe compnents). Mike Robertson Das Fed Subject: Re: RV-List: Sample maintenance log entry From: mr.gsun@gmail.com Dear Das Fed=2C I built an RV-9 for 3 years and then bought a finished (and beautiful) RV-7 =2C sold the -9 partially completed (on gear with canopy done=2C firewall f orward was next).

    Subject: primer! yeah, I know...
    so we're trying to get a handle on the whole internal primer thing, and we're having trouble finding the representative arguments. it's easy to find someone who says "hey, you're what, 60? your plane will last longer than you will no matter what you do - build on." we're a bit younger than that, and I hope our kids will fly our RV after we're gone. it's easy to find scores of people saying "I don't want to get into the primer wars, but here's what I did." anecdotes are fun reading, but since they span from "1952 beaver on floats in salt water, and I didn't die" through "1985 C172 in the midwest and you wouldn't believe the mess I found when I pulled the skins", the anecdotes don't really help all that much either. we even find stuff like the eaa1000 articles from the nineties, which seem to say that if you're not going to set all your rivets wet, you're not serious about corrosion control. (and, in passing, that alodining does as much to prevent corrosion as any amount of other prep and prime can.) that sort of sounds like the most credible argument, but I haven't seen a lot of RV build logs talking about setting rivets wet. why not? we also find people pointing out that common primers are porous, and hence useless for corrosion control - primers are for paint adhesion, not corrosion prevention. hmm. so...I don't want to restart the primer wars either. but I'm wishing I could find each of the canonical points of view, as well stated as they each can be, so we could be informed and decide. I feel like we came late to the party and missed the brawl, and now the information is lost. It would be easy to pick somebody and follow their lead, but something a little more rigorous seems in order...

    Subject: Re: primer! yeah, I know...
    Build and fly........or prime, clean up, prime again the fly....depends on you, and only you. Prime is always a good idea but practical experience shows that good old alclad works great. Some folks do go overboard but its there plane and what ever makes them happy is what they should do. Where the airplane lives is a consideration too. Here in Southern California it is pretty dry and warm most of the year. Back when Comanche's were being built they primered all of the structure, when the Lock Haven plant turned into a submarine factory (flooded) they were transitioning to the PA28 line and for economical reasons they no longer primed, (might have been an option though). How many PA28 have been scrapped because of lack of primer?? I am sure a few but not near the numbers to make a huge dent in the choice. Bottom line, either way has its advantages!! You are going to get a ton of answers on this one. ----- Original Message ----- From: "Nate Lewis" <nlewis@wildblue.net> Sent: Wednesday, February 25, 2009 9:14 PM Subject: RV-List: primer! yeah, I know... > > so we're trying to get a handle on the whole internal primer thing, and > we're having trouble finding the representative arguments. > > it's easy to find someone who says "hey, you're what, 60? your plane will > last longer than you will no matter what you do - build on." we're a bit > younger than that, and I hope our kids will fly our RV after we're gone. > > it's easy to find scores of people saying "I don't want to get into the > primer wars, but here's what I did." anecdotes are fun reading, but since > they span from "1952 beaver on floats in salt water, and I didn't die" > through "1985 C172 in the midwest and you wouldn't believe the mess I > found when I pulled the skins", the anecdotes don't really help all that > much either. > > we even find stuff like the eaa1000 articles from the nineties, which seem > to say that if you're not going to set all your rivets wet, you're not > serious about corrosion control.
