As noted in another post I am in the process of reassembling the refinished landing gear on my PA-30. I noticed that on the nose gear fork there is a small hole above the wheel axle. I've attached a picture to show what I am referring to. I noticed the paint shop did not paint it. At first I thought something must bolt in there though I couldn't think what or why. I checked pictures from before dis-assembly of the gear and sure enough - there is the hole just sitting there empty. I thought I ought to paint it. Then I started wondering - is this a connection point for some sort of towbar? Normally I've always seen the aircraft towed by a bar that fits into the axle cups. Not sure I'll be happy with that approach now that my axle cups are nicely painted but that may just be life... anyway... any idea what this hole is for? Pic attached below...
Thanks,
