Except for the toe brakes, these were delightful airplanes. Six gallons per hour in a Super Cub! I would only change the brakes and seat pans -...

I would love to justify an MT prop for the Decathlon. One of my buddies reports that he is getting poor results from a 4-bladed prop on his Malibu. ...

Sometimes we get sneaky and think of "minor alterations." I can tell you that dope, rattle can, and Aerothane go really well on small repairs. ...

Well, that is a definite plus. Can you release the components that catalyze it? I have had no blistering on the Eko-fill under dope or Poly Tone....

Popcorn, anyone? if it is non-toxic, how come my buddy wore a full body suit and face mask? You ought to be able to spray it with a bandanna...

I could only find a requirement for brakes in CAR 4a under transport. I now have duplicate hard copy of almost everything imaginable - axial and...

I put 1080HDs on, and realized that you cannot rotate the Hydrasorbs - the bolt holes need to be parallel (of course). I did them with the engine...

If it flies, is in annual, and has no paperwork problems it is probably already sold.

Excerpts from 23-27 and related FAA guidance: AC 23-27 Section 1.a. says “. . . You may use the data in this AC as approved data for...

Yes, Steve - many times. Word for word after your last post. I am ready with excerpts. In fact, maybe I will post the excerpts - they come from...

These are not my aircraft, and I do not make a living doing this. I am trying to bring one into compliance (I usually get rapid help with that sort...

I have been searching! I apparently asked the identical question in 2019, and found a Univair statement saying the 1080s were standard. This year...

I don't think such correspondence goes in the aircraft permanent records. It is just part of a formal process, and apparently they have to give you...

That is nice!

Exactly what I need! Thanks Dave - they were looking at transports (STC) and then helicopters (ENG). I suggested item E1 and they said ok. Still...

I got the “Declination” letter yesterday. I always thought declination was something used in celestial navigation. Main reason - cannot...

Nice breakdown. Only change I would make is repairability - Stewarts can be easily repaired. You cannot blend the finish as with dope, but then you...

If something happens to allow a nut to shear .032, I doubt that .040 will stop it. I agree, loose is better than gone, but there are places where if...

Doubt it. And why is .040 so important? Once those nuts start backing out you are in trouble no matter what size safety wire. The wire is not...

Tailwheel steering on the Citabria can be fixed to be as good as a Cub. Parts are now readily available. Proficiency is everything. If you plan...

Yep. I see less value in that than I do in notifying airmissions. The stall warning horn in my Decathlon was set to go on a full 8 mph before...

A flight review is not a check ride. And my stall sequence is now completely outside FAA requirements. I cannot force a student to go beyond FAA...

Took a CFI up yesterday in a 160 Cub. We had to go to 5000’ before he was comfortable, and after a reasonably good straight ahead stall and recovery...

I have a stall series for the Super Cub. Turns out even experienced instructors need "brush-up." You would think that, given that they have to...

I have done only one Cleveland field approval - 310 wheels and brakes on the UPF-7. I have done two Aeroncas with Grove parts, three Grove master...

The way I see it, "thou shalt not deviate." So you install the approved whatever exactly as shown on the 337, sign the logbook, and then after that...

Taylorcraft used them on the L-2. They are probably overkill on a Cub, although they look nice. Mine are Douglas Fir, ripped from 3/4" planks in...

They can. You pay them and they produce approved data. Or you get an ASI to do them free. I prefer the latter.

I am familiar with 23-27. I just discovered that my offer to bring drawings in was not forwarded to the ASI. That may be part of the problem. The...
