Hello everyone,
I have been flying my IIL for about 21 hours. I had to move airports and rent out a friend's hangar. Long story but my wings had to get taken off to make room in the hangar. I never took photos or even thought to take them when I bought the plane. My A&P buddy and his home builder wife took them off (with permission) while I was out of town. I go to reattach them today and realized I have no clue what I'm doing.
I'm an A&P and could figure it out but after looking at plans I'm even more confused. I'm used to bolts holding wings on and am not ashamed to ask for help. I work on jets primarily so this never comes up.
I see we use taper pins in the plans. I have taper pins with threads on the aft side, a bolt head on the fwd side and about 2-7 washers on each.
Dumb questions:
1. Is the nut head to prevent spinning while attaching the nut which acts as a security measure to prevent it from backing out? Or is the nut being used with washers on the aft side to pull the pin aft (forcing the thicker taper into the smaller hole)?
2. How deep do the pins go in? Buddy swears they were flush. I don't remember the fattest part being flush and remember seeing bolt heads sticking out an inch.
3. Do you hammer these in until the sound changes? His wife brings up a good theory that this would give us our depth. To me it could also damage the spar and the taper profile over time(?)
4. I'll try to get a photo of them, but does my taper pin setup sound correct? The read spar pins are missing so that's another can of worms
Any photos of your setups would be greatly appreciated and speak volumes.
I was hoping to find a post I saw a while ago but can't locate it after hours of searching.
