My OshKosh Prop Strike

[apkp777]

I had a similar "strike". My prop hit a wooden runway marker however. Like yours I had tip damage. Mine looked much worse than yours. I sent the prop back to Catto mostly because there was a nickel leading edge defect from installation. Ended up that the tip damage was just paint. He had to replace my nickel leading edge and repaired the tip for free. I'd say yours is mostly cosmetic.

Glad to hear everything appears to be ok with the prop. I saw it happen and my heart sank with yours when it happened. You came over a couple days later and we chatted a bit so I just wanted to shout out and say hi again and glad you posted an update on the topic.

Thanks Brian, It was great to meet you and your family and hear about your trips.

Catto reviewed my photos and wanted a tap test of the nickel leading edge to check for any de-lamination, If no de-lamination is found there is no need to send the prop in.

Walt gave my prop a thorough tap test before I left OshKosh and no signs of de-lamination were found. I also checked the prop tracking prior to leaving OshKosh and found everything straight. This morning I checked the prop bolts for torque and did another tap test on the prop blades. So far everything looks good.

Glad to hear it was not any structural damage. I have the composite Hartzell, so learning the tap sound is in my future.

After a friend's RV suffered a hit and run prop strike by a high wing plane, I always make it a point as I am chocking, walking around etc to turn my prop to the 3-9 o'clock position...it has worked so far

I have always positioned my prop at 6-12 o'clock position, especially while at air shows, since it is a wood prop and I don't want people walking into the tips. I have a friend who several years ago while at Oshkosh had the tip of his prop damaged by someone walking into it.

I guess you can't second guess where the damage might come from.

Andy, Glad to hear that it appears the damage you have is only cosmetic.

I have a three blade. I usually like the one blade straight up high and the two lower split at the bottom in a y, but to hang the eaa sign on, i turned it to 2/10 so one blade was straight down at 6....it was as low as a three blade goes and the idea of high wing taxing into my plane was not even a thought. Its was literately 1/32 of an inch contact....just enough to slow motion turn blade a bit and leave transfer.

I have thought of finding pics of the planes in the row and getting tail number but the dude didnt do it on purpose...and its possible isnt even aware.

This might be OK for short periods, but normally a wood prop should always be left in the horizontal position. Wood has a lot of moisture content and leaving the prop vertical causes the moisture to migrate toward the lower tip throwing the prop out of balance.
