Default Bird strike wing damage how to fix???

A good buddy had the unpleasant experience of smashing a swallow bird today. Here is the damage. There is no hole, just a good dent just outboard of fuel tank, and ribs seem to be ok.

Any suggestions on how best to fix? He has a few trips planned including wanting to go to KOSH this week. Need to figure out how best to tackle this one quickly and properly.


Thanks.

Default Pull the tank

Best fix, pull the tank and work the dent out...quickest fix, fill it with some bondo and put aluminum speed tape over it...may match the polished skin pretty well. Believe it or not, that's how we do interim repairs on the big jets when birds or hail damage the skin.

I helped a friend fix his 4 following a turkey vulture bird strike earlier this year.
We replaced the skin and several ribs and added a doubler on the outboard spar support. Total cost was about $500.
I did make sure there was no spar damage due to the size of the bird strike. There was no forward or aft sweep. I used the plumb bob procedure.

Planning was much different than the typical building process as we had to use some cherry rivets due to limited accessibility which you don't normally encounter in the building process.

Here's the VAF thread.http://www.vansairforce.com/communit...ht=bird+strike

Find the music store in town that provides all of the brass instruments to the local school system. Call them about using their magnet and metal ball to work out the dent.

Talk to some of the local auto body guys, they might have a good suggestion how to pull the dent out. Then use bondo.

Remove the ball from your trailer hitch, remove the fuel tank, reach in through the rib holes and gently work it out as close as possible, with the ball..then Bondo the remaining small dents.

Works on our ag airplanes

Best,

Magnetic english wheel, outstanding idea! I have some super strong magnets from a 50kw electric motor project, they should be perfect to remove some rivet driver marks on my wing (oops).
