Re: Crack in flap

Post by 8281 »

I just looked at a flap and I Believe a Good Sheet Metal Person
can do a repair by placing a doubler on top of the flap !
All of the rivets where the Flap bracket attaches to the place in question are accessible from the outside !
I'm not an A&P or IA , but have worked on Light A/C for several years.
To Me , It would only take 30min. to repair if the flap was off the wing.

But without seeing more of the flap bracket where it attaches to the flap,
there could be more damage than meets the Eye !

So check with an A& P that's good with Sheet metal repair!

You need a view like the one above. Look closely at the relief hole in the spar where it's bent from vertical to horizontal. Also, you can pull the flap down by hand and get a look at the bracket and spar from the forward facing surface.

I haven't looked at one recently, but I think I'd try to put the doubler on the underside of the skin, if only for looks, but I'm thinking you'll need a rivet or two on the "inside" (outboard of the rib) to do it right.

Good Suggestion John C.
Doubler under the Flap Skin Would be neat !

Also, to the owner.
Make sure the bolt that attaches the flap bracket to the flap torque tube is not tighten down!
As it needs to be Loose as a Goose to allow for the difference in angles between the flap torque tube
and the wing Dihedral!

Yes! It's sort of a crude universal joint.

Maybe I didn't state that very well. Look at the area in the circle:

Please show the picture of the same location on the opposite flap. I don'\t want to drive 34 miles just to see mine. :)
