Hi Tim, Thanks for the reply, no offence is taken. We will look at this aspect of the wheel tomorrow. I will let you know what we find. There were only very very faint skids makes on the runway, you had to look very closely to see if they even applied to my situation. As I mentioned , the tires ( ei...

Hi Rick,
AN bolts are correct for normal application,
MS are called for when on Skis.

Tim, That is a very interesting, point you brought up. Thank you. We will certainly look into that possibility, how ever I do know that for certain that the tire did not lockup and skid, as we have very closely inspected the tire for skid indications, and non are evident. George, Yes they are certai...

Has any one ever seen anything like this before ? I landed, in Buffalo, calm wind, a good touch down, NOT hard ! a very slight swing to the right as the tail came down,... I apply left rudder, more right swing, and some left brake, and next thing I know , is I hear a bang, :oops: and I get as hard a...

Getting back onto the topic,.. I find the first notch helpful when trying to "pop it off " "on skis in deep snow " I start with 1st notch, then once I get 40 mph , I can find the flap handle easily, and aggressively pull on 20 degrees and it usually pops out of the snow, and into...

I am certain that the ground clearance is not an issue. Wicks Inc. in Alaska, has an STC for the DM 80 series prop on the 170 Series LANDPLANE . I have this STC , it is well documented. It has instruction procedures , ICA, and an Approved Flight Manual Supplement. The STC does NOT require large tire...

I also purchased the STC from Wick Air in Palmer Alaska. ( SA 632AL ) Which is actually for a DM 80 series prop ( 8 bolt flange ) His STC includes a nice Flight Manual Supplement, the limitations instructions, and ICAs. Also if you look up the Type Certificate for these Props, P-857. On Page 4 near ...

We interrupted it as follows. On my copy of SA7441SW, on page 1of 2 installation procedures, item 4 , which refers to propellers, , section A talks about sensenich an McCauley Props, , then it states , " and1A175/SFC8040 seaplane not to exceed2360 rpms. " It was interpreted as the 1A175/SF...

Hi Go to http://www.mccauley.textron.com/MAG.pdf to down load the PDF, on page #413 , on line # 8 you will see that the 6 bolt prop is listed, ( 1A175SFC 80/40 ) for the 170B with the O-300D. The STC # is SA7441SW owned by the 170 Association. if the link does not work go the McCauley Propeller webs...

Hi I asked the same question, and found the answer through the McCauley website, there is a PDF which has all the STCs holders. In it I found the STC holder is The 170association !!!!!. It is included in the STC for the O-300D in the 170. The 1A175SFC 80/40 is listed. There are several STCs for the ...

Hi David, Yes, Thanks , that is what I was looking for. But that brings into question, how much is ,.. " positive clearance between the propeller and the ground in the level takeoff attitude with the critical tire completely deflated " does that mean the 9 inches ? or just, some clearance ...

Thanks Joe,
I would be interested in hearing about what performance you get ? ?
Are you on wheels only ? What size tires do you run ?

I would really appreciate any paperwork you could share with me ?

Thanks John

Hi I am looking at putting a 1A175SFC 8040 prop on my 170B, for Ski season, I have a O-300D engine. I recall reading some-ones post about the required criteria,... ? Something along the lines of X number of inches required from the prop tip with one main wheel tire deflated ? Also does anyone have a...

Well Done !

I thought that a "dampened Crankshaft " was required for the 35 amp Gen ?
I am not certain if it is required for an alternator or not ?
