Unless you went through Navy electronics schools, current flows positive to negative. Electron flow is negative to positive. It matters not how you...

Maybe it fried an instrument? There are several things that cannot tolerate reverse polarity - the GTR-200 specifically says damage will occur. ...

Yes - my PMI said the same thing. I asked him to put that in writing and he agreed. That was six months ago - he doesn't check his e-mail, but he...

Over on the Champ forum they are discussing 8:50 tires. Turns out that they are not on the type certificate, but the factory says they are on the...

Yes - a huge percentage of IAs do not understand 337s. I am not a full time mechanic, but still I see bunches of 337s for alterations approved by...

Me too - but this is not my aircraft. I am just trying to make it legal. I shouldn't have to force the owner to buy a $3000 kit.

That's true, but if you can show that an STC installation is in fact minor, then you do not have to buy the STC - just make a logbook entry. ...

The actual STC documents leave out the J4 and J5. No idea why. Been on the aircraft for a quarter century.

Nope - cannot find it. Hard copies are at the FSDO, still being ignored. It is out there, and can be copied.

Well, it is in my files as a pdf, but I cannot get it to reproduce here, so just google the Piper part number. This is a 1941 drawing, but I have...

Memory is getting fuzzy, but I think Univair advertises its J3 gear leg as suitable for J5 and PA-18. I'll check back later and if no one else...

I am 200# and have been for most of the last 60 years and 6000 hours in my J3. Door hinge is still ok - cannot get in without sitting on the door...

4-40. I hate to say it, but Piper probably got them in bulk at the local hardware store. You can get better steel from Micro Fasteners, but I have...

Well, me too. I never ask for a short approach, and if I am #1, it is done at idle in almost everything I fly. That includes the Mooney - looks...

That is good to hear. I was fairly good at acrylic enamel, and now am equipped with an external air face mask. I may give it a try.

I may have one of those. I have been using the Graco setup, and so far have avoided catalyzed paint. Let me look.

By golly, you are correct! I sort of thought it was out of the Airplane Flying Handbook, which is not a source of definitions. The Advisory Circular...

Martha Lunken said "half as many of us and five times as many of them." No wonder they cannot return our calls and e-mails - they are too busy...

Back to the short approach. I submit that we now need a definition - a published definition - of a short approach. I suggest anything shorter than...

Yeah. Best not to do any non-pre-briefed formation flying. I refuse to participate in those well-briefed 20 plane holiday fly-overs, because even...

Not ours. They are a major flight training operation for future airline pilots. We have a viable workaround, as described above. I just wish they...

I have had the same experience with Serco towers (contract). I have had some luck calling the tower chief to get his/her folks in line. First,...

Edit: Skywagon's post appeared after I started typing. The "45 degree base leg" is a poorly stated attempt to describe looking over your shoulder...

I of course agree with the above posts. The 1/4 mile point on our airport is exactly at the eastern edge of the pavement. The 45 degree point...

I had one guy flunk because I had not taught him a stabilized approach - in a J3. If the examiner had simply asked for a 60 mph power on approach he...

If it is pretty nice and priced correctly I would go look at it rather quickly with cash in the overnight bag. Yes, take a mechanic with you who...

I respect Mike’s opinion, but my impression of the ACS is a lot like my impression of the Citabria spar inspection - cannot be done properly in any...

I thought so too, until I climbed into the front seat and tried instruction. That was with the horrible original brakes. Back seat? Easy, like a...

Anybody that teaches in a UPF-7 has my admiration. I won't touch that unless the student is an accomplished tailwheel pilot to start with and the...

Aren't these quarter million dollar airplanes? Isn't their main mission to see how gnarly a strip they can get into/out of? If Tac Aero is teaching...
