New to the list and I did not find the answer in the archives (RV10 builder now building an Cool.

Asked Van's about cutting out the area between the lower and middle lightening holes to improve access to that area, especially the attach bolts. KenS sent me the following reply this morning: "We know that some builders have done this, but we've never found the need. We have no engineering data one way or another on such a mod so we have no basis for advice."

Have any of the 8 builders done this modification and were you able to do any engineering analysis on resulting tower?

I plan to cover this area with a plate using plate nuts as was described in one of the forums.

Thanks - John Miller (Grumpy)

John,

I wouldn't do it. My experience has been that the gear towers in the -8 are a little underwhelming in terms of strength to begin with. The attached pictures show what happened to my RV-8 when I got it sideways during a high speed taxi incident. I had already landed and was making the turn off the runway onto the taxiway. I wish there was some engineered, accepted way of beefing up these gear towers. It would have been a lot less work than having to rebuild a whole new fuselage...
