I just realized my AA1A canopy is backwards thanks to this video. Doh! I've had it for 2 years. It had a new windshield, canopy, and a "fresh annual" when i got it. It was a blatant pencil whip so it doesn't surprise me at all. We're currently in the process of doing a O-290D2 swap on it. I'm assuming it's not reversible since the holes need to be drilled to fit.
Sorry the info in the video applied to you, live and learn they say. Glad you have one of our birds though.
It's a myth that all plane motors rebuild the same. Gentle care and good fluids help. Too much love can backfire. Everything wears out someday.
Correct, but start with the best you can. Being cheap does not work out.
I don't like to make negative comments because they aren't productive, but this time around I have to tell you guys at "Grumman Pilots" a thing or two. Below I commented that I bought AuCountry's nose strut fairing and that it lowered my peak cht by 20 degrees. You made a comment implying that I was ignoring the real problem while the the "disease" goes merrily along. First off I am deeply insulted by that comment. I consider it smug at best and at worst ignorant. I meticulously maintain my Cheetah and over the years five mechanics have praised the care that I give toward all aspects of her care. Engine cooling issues are a real concern and all the mechanics that have addressed my issues see no real,problems with the baffling. You apparently have the magic bullet . I have to add here that you flatlanders probably don't have the challenge of high temp desert flying when temps are often in the 90's. Not all of us have your expertise at hand or can fly a thousand miles for you to bless our humble ships. So to imply that I have been ignoring a problem is elitist for you to say. In fact, I have watched many of the videos you guys have produced and in my opinion, for the most part, the airplanes you work on look like garbage to me. No wonder you have such a cynical view. I would be ashamed to bring an airplane to you that looked like the ones you get. So just to finish I think you folks are snobbish and I wouldn't let you touch my airplane unless I had the many thousands of extra bucks it would take for you to do what you guys "think is right".
Interesting view, I was mentioning that if baffle and seal are in good shape then the plane will be cool enough un the engine compartment, additional tricks not needed.
The photos of the "nice leather interiors" shown early in the video are ours, not theirs, and should be removed. Those photos were pulled from our site.
How can something so simple be so complicated.
An engineer thought he had a better way to make the mousetrap.
I would love to have this installed links for the shops!?
They are no longer available. Ken passed away. FYI
Thank you Roscoe, these are so easily overlooked when chasing over temp engine problems.
can you go over the jacking system used in the video?
Have a video dedicated to all the methods.
I've been using an MT on my 1975 Tiger for a number of years now. Trouble free, quiet, and lots of power for getting out of my grass field.
They are nice to have.
I just bought this fairing which is now $280 plus shipping. While I appreciate what Gary has done I have to say that for the price it might not be worth it. The fiberglas is HARDLY paint ready, is full of pin hole blemishes and to be done right will require alot of prep. It ain’t paint and go. Fine, just sayin’ that for $280 bucks it oughta be. You make your choice. PS. I have flown with the new fairing for a couple of hours now in 80 degree, density altitude of 7,000’ and my warmest CHT is cooler by 20 degrees. I am very pleased with this result and it looks so much nicer than that old boot.
A properly baffled and sealed tiger engine runs fine, these are treating a symptom while the disease goes merrily along.
Can you give me a contact number to purchase? How did you go about purchasing? I need one for my tiger
@@hsilva92 Look up AuCountry in California, that's Gary.
Thanks ❤
Can you buy just the floats? My senders work fine but just found the floats work badly and just about to fall off
No, but you can send them off for rebuild.
@@GrummanPilots thanks. Where can I send them and can I get exchange senders?

Point Of View!! Did anybody review this before posting it? You need to place the camera so a hand doesn't block what you're trying to show. Putting up a defective video like this one is worse than not posting at all!!
Well we have learned a few things since that video 8 years ago.
Eaton makes a great product and their customer support is the best. Ask me how I know! My new Eaton Polar Air 7.5 HP compressor failed when less than 2 years old due to a failure in the pressure lubrication system. Eaton sent me a new pump at no cost and did not even want the old pump back. The replacement pump just started showing signs it might be about to suffer a similar lubrication failure and it is only 10 months old with less than 100 hours of running time on it. Turns out my infrequent use of the compressor is resulting in moisture contamination of the oil from humidity entering the crankcase via the breather. Most of the time, the compressor auto-starts on low system pressure just to make up for slow leaks in the air piping. It only takes around 30 seconds of run time to fully recharge the system and then the compressor stops. It never comes up to any operating temperature above ambient and is thus not heating the oil enough to drive out any moisture. Over time, the oil turns into a milky sludge plugging the oil pump inlet screen resulting in little or no oil pressure. Some of the condensed moisture pools at the bottom of the sump where it is sucked into the oil pump leading to the crankshaft ball bearings being lubricated with water, not oil. Corrosion sets in and the pump eventually locks up and will not turn over at all. This should not be a problem for anyone who runs the machine long enough for it to come up to full operating temperature, but for infrequent users like me, it is a real problem. Eaton is now offering an electric heating pad to affix to the bottom of the crankcase to maintain the pump and oil above ambient temperature even when the machine is left off for long periods. Eaton's service manager advised me that they are seeing this problem primarily in the humid southern states along the gulf coast, not so much in the drier western states. Keep an eye on the oil level in the sight glass. If the oil level appears to increase and/or if it starts looking a bit cloudy, change it immediately. Do not wait until the next scheduled oil change. It may be advisable to do more frequent oil changes than the factory recommended intervals if your environmental conditions and use patterns are leading to premature lubrication failure. Yes, I know the compressor has a great warranty, and Eaton will replace it at no cost if it in warranty, but believe me, it is no fun having to disconnect and lift one of these heavy pumps off the tank and put another one on. Changing oil is a lot easier.
Thanks and good to know, we will watch it.
Can you still buy these vents now for the AA5B 77 model?
Yes, Call Roscoe, they are $50 a set plus 10 dollars postage and insurance. FYI
How comfortable is the AC? It's going to be 100 this weekend at the show.
It was very hot in 2010 and the AC in the text was arctic, very nice and comfortable place. Bathrooms are AC'ed as well.
Hi, Can you tell me what the part number the rivnuts are that go into the spar? Mine have broken out and someone has done some poor attempt at "repairing' it.
Call Fletchair and order the parts. That is where I get them.
I have the KFA prop, does this still apply? If I went to Sensenich, what pitch is the best? I see you can have from 60-65inch pitch.
I had one too, AD does not apply to that prop. In the Sensenich, get a 63, better airfoil.
Gotta love the guy at 9:35 getting absolutely blasted after losing his hat and glasses, then continuing to chill in the propwash lol
Everybody had a good time.
Cylindrical tube spars are equally strong in positive and negative G's. They are easy to build and integrate into wings. The Grumman design can trace its way back to Jim Bede's BD-1.
Yeap, way better than an I-beam.
@@GrummanPilots I commented on the wrong video, was singing the praises of Grummans design though. Have a friend with a tiger who loves it. I appreciate all the content you have about them.
I’m having a heck of a time getting my flap motor out! Were is THAT video?!?!
Not hard, just take your time, welcome to the club for working in the hell hole.
Thanks. Excellent. And only video... I could find on this topic. QUES.... is that spring with the insert that goes into the wire...one piece? and where do i buy those?
Call ElectroAir and ask for parts.
@@GrummanPilots thanks so much!!!
thanks for the video. you said it's important to attach it in the correct orientation.. what is the correct orientation? is it fat side in or out? do you glue it on the door body or the flat part that sticks out over the doorjam?
Fat part on door, slit in seal at the bottom.
Send me an email when we have a fly-in, I would have brought by a brisket if I had known.
Will do, thinking about a day in July.
@@GrummanPilots That sounds wonderful!
The difference in price between those radios is because the Baofeng is a Chinese piece of junk, the Yaesu is a Japanese quality radio. There is no comparison in quality. Of course the Baofeng does not work on the aviation band then the comparison is worthless.
Still not bad for a 25 dollar radio.
Can these spars be replaced? Will this airplane ever fly again? Can you find enough replacement parts?
My guess is it would been more costly to fix than it was worth, I dont see anything saying what happen as it was years ago.
Yes they can figure 4 - 5 man days of work to do.
according to Lycoming Service Instruction 1583 (may 2022) you should be using a locktite aviation gasket sealant ( or permatex no 3 aviation gasket sealer equiv) in addition to dimpling the expansion plug center. Lycoming also requires you to use their Welch plug driver but who is gonna pay 1800 bucks for that. These instructions are also in the engine overhaul manual.
Please note that this video was published May 2018.
Sorry I didn't get a chance to come by yesterday will try to make it to the next meeting 😢
We look forward to it.
Thanks for the trip in the past aa1b owner is there going to be an autopilot for the 2 seater
Treo says they are working on it.
With the incident of a plug failing right after installation at KLUK yesterday, I'm really curious if installing it like this is going to be found as the cause of failure. This is the kind of tutorial video that gets airplanes destroyed.
Funny, followed Lycoming service letter to the 'letter'. Check after engine run for leaks, but usually good to go.
@GrummanPilots You'd better read it again because they specifically say not to drill out the old one and to only use tool 64681 to swell it in place. See accident report ERA21LA006 from 2020 too.
To get the back off: after taking out the 4 screws, use a utility knife blade and gently work the sharp edge between the rubber diaphragm and the metal housing, don’t put more than a 1/4 inch of the blade into the seam. Just enough to create a gap. Cut along the diaphragm and work around the circumference. Go around a couple of times with increasing gap every pass. After getting the back cover off, remove the screws on the front and the hardware. To get the glass off, use a wooden dowel to push the glass from inside, using now open back as an access point. An oval shaped, unsharpened carpenter pensil works really well as a pusher, or use two for even pressure. Hold the housing with glass pointed up with one end of the dowel or pencil resting on inside glass corner and the other end resting on the table. Gently press down on the housing and the glass should start to separate. Move the dowel to opposite corner and the glass should pop off. Do not try to pry the glass off the front with a flat head or similar. Remove any old seal material careful with a razor blade or something like green brillo pad. Clean the inside with brake cleaner if any debris fell in before installing any gaskets. Hope this helps.
Good to know, sometimes they can be a pain. Not for the home pilot to try.
I would rather have rivets my friend, although I do like Grummans!!! Great videos!
You can always add them to your comfort level!
Also need your contact info to set up a pre buy overview please.
Roscoe, Yankee Aviation, 513-519-7008
Can you PM me the cost of this procedure on a 72 Traveler please.
Figure 2-3 days to remove and reinstall.
Hi thks for nice video. Please let me know what is the difference of the -3 and -4. My dealer suggest me a -4?
Just part of David's or the Factory's reference number. Pump was tested and was passed to be scribed.
This will be more useful if you can show the airplane and show the cables! All pictures from golf,e is something we all ca do! But we need some input about what is the master switch is connected and will be easy to understand it!
Master is connected to battery. When the relay is grounded (turning on master) it passes full current and the voltage to the starter via cable. When starter button or key is turned, starter relay is grounded and sends voltage to starter. Relay prevent back magnetic induced voltage when the circuit is energized and prevents backfeed.
What aircraft is that cessna?
Actually a Grumman airplane.
Sooo, what’s the advantage beside prop clearance?
Full RPM on takeoff so 180 ponies not 135 pulling you into the air. Pushes you into your seat and is so smooth when flying.
Out Freakin Standing
Literally!
Estimated total installed cost?
Depending on the shop rate of your facility, figure 20-24 hours total to get it all in and tested and signed off. Hardest part is installing the controller in the panel and the brush block alignment.
Can you get one of these on a PA 28-140?
@@av8tordan514 Call MT and ask them, they service a lot of planes.
Good evening sir , thanks a lot for this crucial information, please sir for the fuel hose, expect brown rubber hoses is there another hose inside ( brown rubber hose) . The purpose of the brown hose is to prevent high temperature? Best regards
No it is a lifetime hose, no time limit.
@@GrummanPilots , hi sir , so on condition. Best regards
Thank you!!
You're welcome!
Thank you!!
You are very welcome. No rest areas to pull over in up there!
Do these fit the 74 traveler?
Yes they do, order a set now.
@@GrummanPilotsdo you have a link to purchase?
@@speezy1414 Sure email [email protected], $60 a set for AA5B which includes postage. Send your mail address as well.
There does come a time when it's okay to say "Crate motor and accessory support kit" or at least a voltage regulator and condenser lol. Fun video.
It did come off and get overhauled. FYI
@@GrummanPilots Oh I imagine. The ole gal deserved (needed) it. Great video.
Yeah, pretty sure you’re supposed to remove the springs!
Actually with this tool setup you do not.
Does any one have the STL file so I can print these. Need one
Contact Roscoe.
Why isn’t anyone building new spars for Grummans?
The factory has not been interested, material cost is high now and the jig for drilling them is missing.
How common is spar corrosion? I’ve been looking at a Cheetah to potentially buy, and now you have me spooked. Between torque tubes, fuel leaks and spars, you have me rethinking this.
Not very, it comes from no one looking there for years.
