No, I do not,, but I believe the 170 association does.Tom, do you have a copy of the Byer letter mentioned?
We've not seen much of a slowdown,,If you are worried about speed you're in the wrong aircraft.They do slow you down quite a bit, so what is a few MPH to look cool
I believe the letter plainly states the FAA sees no difference in the size of the tires being any problem.I suppose it depends on the contents of conversation and the earlier letter that was referenced.
That's what I though too, so they went on as a minor alteration, noted in the maintenance logs as such.It sure looks like it.
I've got 8.50s on my Citabria (had 7x6 previously and 6x6 with pants before that). Might be a 2-3 knot difference at 2500rpm but none at lower power settings.We've not seen much of a slowdown,,If you are worried about speed you're in the wrong aircraft.
The 8:50s just roll easier in the grass.
If that's what you think, go for it. I feel the letter in your original post summarizes a conversation, and says "as outlined in another letter". Without that other letter, I don't see that you have all the details.I believe the letter plainly states the FAA sees no difference in the size of the tires being any problem.
I have read both letters, which say the same thing. in so many words.If that's what you think, go for it. I feel the letter in your original post summarizes a conversation, and says "as outlined in another letter". Without that other letter, I don't see that you have all the details.
Weight and balance is always changed on a 337.If you are putting them on as a minor alteration why does the letter tell you to file a 337?
Not a matter of "REQUIREMENT" just a matter of how to record the W&B in history records, when it is recorded by 337 you can always recover the data.Empty Weight and Balance changes do not require a 337. That would imply, every revision/amendment, including weighing the airplane, requires filing a 337. Unfortunately, small personal aircraft typically do not have a great place to store the weight & balance records, and are typically terribly organized. Larger aircraft are typically better.
